I decided to devote the next few materials to correlations.

The most important thing for all traders of the Russian stock market is the correlation between the Russian market, the S&P500 index and oil prices. There are semi-automatic systems (I saw one of them with my own eyes), when our traders intuitively buy or sell contracts on the RTS index, looking only at the movement of oil prices and S&P500 futures.

In fact, fundamentally, equity markets are primarily a reflection of the interest rate market (bond markets). Interest rates determine in which direction money flows. Everything in the financial world depends on the interest rate market: both currencies (through interest rate differentials) and commodities markets and equity markets. In this financial world, everything is interconnected.

The US interest rate (bond) market is the largest in the world and therefore has the greatest influence on what happens in other financial markets.

However, this relationship is very complex and difficult to track. It is much easier to track other interactions that are more clear and explicit.

The Russian market, in a “rough approximation,” can be considered a derivative of the S&P500 futures (index) and oil prices.

In general, little depends on what is happening here in Russia. It is rare that any event in Russia will cause any noticeable reaction on the entire market. I don’t mean corporate news, although here, too, an accident at some Lukoil enterprise does not always affect its shares, but the same accident at an Exxon plant (paradox) will cause a fall in Lukoil shares. But bad employment data in the United States can cause a real collapse in the Russian market. The financial market is full of such paradoxes.

However, we are not alone. Almost every stock market in the world is closely related to the American stock market and reacts primarily to what happens there. And here, in addition to the fundamental reasons for the interaction of capital markets, the widespread use of automated trading tools also has a strong influence.

This manifests itself especially clearly at the micro level (tics). Each tick movement of the S&P500 index up or down is immediately responded to by a corresponding change in the FTSE, DAX, MICEX, Bovespa indices. This kind of correlation exists everywhere and is the basis for traders’ decisions.

How does this show up on the graphs?

Next are several graphs that show how the S&P500 index, RTS index and oil prices interact with each other. These charts show the change in the S&P500, the RTS index and oil prices as a percentage since the starting point specified on the chart.

The figure highlights the situation in March, when the RTS index followed oil, and not the S&P500 index. This was a period of aggravation of the situation in North Africa and the Middle East. Higher oil prices had a negative impact on the American stock market, but at the same time led to a rally in the Russian stock market.

Pay attention to one more fact: a reversal on the Russian stock market almost always occurs a little earlier than oil prices do.

The following chart shows the same correlations since Ben Bernanke spoke at Jacksonhall where he announced the upcoming QE2 program.

As we can see, almost until the New Year, the S&P500, the RTS index and oil moved almost synchronously. In January-February, there was a seasonal correction in oil, but the Russian market continued to grow along with America, absorbing the money that is usually allocated to investment funds at the beginning of the year.

The following chart shows the same correlations since the peak of the US stock market in 2007. The impressive parabolic rally in oil was still only slightly able to drag down the Russian stock market.

What is noteworthy in this graph is the stability of the spread between oil prices and the RTS index.

The following graph shows us the correlations since January 2004. Investing in the American stock market did not bring any profit during this period.

And finally, the most impressive graph from this series: since the beginning of 2000

As we can see, while oil and the RTS index showed very strong growth during this period, 450% and 1500%, respectively, the American stock market practically did not leave the negative zone during this time.

Undoubtedly, there are other factors that influence the Russian stock market. For example, the ruble exchange rate. The strengthening of the ruble exchange rate leads to an influx of money into the Russian market. An increase in the refinancing rate leads to an increase in the ruble and, accordingly, contributes to the growth of the Russian market (usually it is won back in advance by insiders).

When the dollar becomes cheaper relative to the ruble, then, if we assume that asset prices in rubles remain unchanged, they should therefore rise in price relative to the dollar and other currencies.

Perhaps the dependence of the Russian market on oil prices expresses the relationship of the market with changes in the exchange rate of the national currency with some correlating coefficient.

Therefore, although there is also a certain correlation here, there is no point in identifying the interaction of the RTS index with the exchange rate of the ruble or some other currency.

In short, the following conclusions can be drawn:

The interaction of the Russian stock market with the S&P500 index reflects global market sentiment towards stock markets in general

The interaction with oil prices reflects both the traditional dominance of oil and gas stocks in Russian indices, and much of the interaction with changes in exchange rates.

There are other correlations that need to be taken into account when investing in the Russian stock market: for example, the interaction of the Russian market with the inflow/outflow of foreign capital.

RTS Index was a key indicator of the “Russian Trading System” - a platform formed in 1995 in Moscow. After the merger of the RTS exchange with the MICEX in 2011 and the emergence of a new legal entity, the index came under the management of the created Moscow Exchange.

RTS index rate right now on the stock exchange online

The oldest stock index, the RTS, reflects the dynamics of 50 companies trading on the Russian market with the largest capitalization. The list of instruments until December 2011 was compiled by the RTS stock exchange. After the merger with the MICEX, the list began to be formed by the Moscow Exchange.

• There is also an index RTS ─ 2, including second-tier securities;
• RTS Standard, reflecting the dynamics of the 15 most liquid shares of the domestic market;
• RVI, which is a volatility index and seven sectoral indices.

The RTS index, calculated in dollars, has been experiencing a permanent decline since 2011, when it reached 2,134.23 points. Economists see several reasons for this: the gradual displacement of domestic companies from the global market, the gradual replacement of the dollar in interbank and international settlements, the intensification of trade in the ruble-yuan pair and the transformation of the ruble into the reserve currency of trade in the CIS.

The introduction of the RTS index coincided with the birth of the exchange of the same name: on September 1, 1995, it was introduced at 100 basis points. Like the competitive one at that time, it showed a dizzying rise until 2008, reaching 2,498.10 points on May 19. True, by October 28, when the American mortgage bubble collapsed and the crisis began, the RTS Index fell to 549.06 points.

Beginning in 2010, the index position began to recover and lasted until 2011. On the eve of Cosmonautics Day, on April 11 it reached 2,134.23 points, after which the upcoming

merger of the RTS and MICEX exchanges, and it went down. If in this year the maximum quote exceeded 2,100 basis points, then by 2015 the peak was 1,092.52 basis points. 2016 started in minor - 730 points.

To add shares to the RTS index, certain conditions must be met:

• Securities must be traded on
• The liquidity threshold should remain at the level of the 50 most traded instruments for a long time.
• After the initial public offering of the company's shares on the market, at least six months must pass

Before December 2010, changes in participating shares occurred on the 15th day of the last month of the current quarter - in March, June, September and December. Since 2010, the dates have been shifted by one day in order to unify them with the MICEX indices - the composition changes on March 16, June, September and December. The selection of shares is carried out by the index committee of CJSC MICEX Stock Exchange, which includes analysts and professionals.

Calculation of the RTS index

The methodology for calculating the RTS index is similar to that of the MICEX, with the only difference being that the basic formula contains a cross rate, which means the value of the quoted share in rubles.

• I сn– the value of the dollar index at the moment n;
• MC cn– the total value (capitalization) of all shares at the time n;
• D cn– value of the divisor at the moment n;
• The divisor is 148,870,001.744.

The capitalization of companies is calculated using the following formula, where:

• N– total number of shares;
• P ci - the price of a particular share, expressed in US dollars;
• Q i– the total number of shares of one category (type) of one issuer;
• FF i– correction factor taking into account the number of securities of the same type in free circulation (free-float);
• W i– coefficient limiting the share of capitalization of a particular stock (weighting coefficient).

The share price in US dollars is calculated using the formula where:

• P i– share price in rubles;
• K n– exchange rate of the US dollar to the Russian ruble at the moment.

Advantages of the RTS Index

• calculated in dollars;
• is the second most important index of the post-Soviet space;
• has been under pressure from bears in recent years;
• reflects the state of a large number of participants - 50;
• is an indicator of the participation of the American currency in settlements.

The RTS index is strongly tied to the commodity sector - oil and gas production enterprises account for over half of the capitalization. The second most important segment is financial, it occupies 17%, followed by metal mining - just under 10%. Consumer sector - less than 9%, telecommunications - less than 7%. Transport and mechanical engineering - less than 1%.

Considering the desire of the United States and OPEC to squeeze Russia out of the world hydrocarbon market and replace oil and gas with shelf products, constant disputes regarding Arctic oil and opposition to the construction of “streams” - northern, blue, Turkish and “Power of Siberia” - the role of the RTS as a significant indicator of the domestic economy, under pressure.

Recently, the leaders in decline have become not oil sector companies, but financial institutions: the same Sberbank, which has always shown stable results, is capable of losing up to 2-3% per day. Quotes from Yandex, Norilsk Nickel and RusHydro are not always successful. Although the last two companies are included in the first echelon of the MICEX and attract stable interest from serious investors.

Interest in shares included in the RTS index is due to the fact that these assets have maximum liquidity and the greatest attractiveness from both investors and speculators. The total capitalization is $117.4 billion. This amount, of course, cannot be compared with the American stock market, but nevertheless it is a very impressive figure.

Dependencies

• commodity index, tied to oil and gas prices;
• is losing ground due to Moscow’s refusal to pay in dollars;
• depends on the global situation more than on the situation in Russia;
• is in the shadow of the MICEX, which seriously hinders development.

Buy RTS index

To make money on index movements, you need to buy or sell a futures, option or CFD contract on the RTS. At the same time, it is important to understand that these are already instruments of the derivatives market and they all have one or another lifespan (usually several months). This has a particularly strong impact on futures and options trading.

Both stocks and indices are often used to forecast the foreign exchange market. It’s not surprising, in this world of speculators, everything is interconnected one way or another. Of course, the stock market is the most frequent guest of financial news on TV and on the Internet. Shares this, shares that... Apple shares rose by 5%, well, great, I just love my iPhone.

Here we can immediately see the connection between stocks and currencies. For example, if you want to buy shares of a Japanese company on the Tokyo Stock Exchange, you can only do this in the national currency. As a result, your rubles or whatever you have in your stash will need to be converted into yen (JPY), which naturally leads to an increase in demand for it. The more shares are purchased on the Tokyo Exchange, the more in demand the yen is. And on the contrary, the more currency is sold, for any purpose, the less its value.

When a country's stock market seems tasty and nutritious to investors, they begin to flood it with money. Conversely, if a country's stock market is in ruins, investors flee it headlong, looking for more attractive places to invest.

BO and Forex traders, naturally, do not buy shares (except perhaps CFDs on them), although many BO offices accept bets on their quotes. Despite this, the state of the world's leading stocks should be of primary interest to you.

If one country's stock market performs better than another, capital from one country will flow to the other. This will have an immediate impact on their currencies. Where there is money, the currency is stronger, and where the stock market is weak, the national currency weakens.

• A strong stock market means a strong currency.
• A weak stock market means a weak currency.

In other words, there is often a direct correlation between the state of the stock market and the exchange rate of the national currency. The yuan fell - before that the Shanghai Stock Exchange collapsed. MICEX (Moscow Exchange index) is growing - the ruble is following it.

The easiest way to track the state of the stock market is to put a special index on the chart. It has a price, like every asset, and it is very convenient to monitor it.

Major world indices

Let's look at the key world indices that interest us. As you will immediately notice, many of them correlate and complement each other.

Dow Jones Index

The oldest and most famous index in the world. In fact, there are several of them, but the most popular is called the “Dow Jones Industrial Average”, also known as the Dow Jones Industrial Average (ticker DJIA).

A key US stock index of 30 companies with publicly traded shares. By the way, despite the name, these companies are not particularly connected with industry, because it is not in favor now. There are simply 30 of the largest companies in America.

This index is closely watched by investors around the world. It is an excellent indicator of the overall state of the American economy and reacts to local and foreign economic and political events. The index tracks incredibly wealthy companies, you've heard of most of them. McDonald's, Intel, Pfizer - it's all there.

S&P 500 Index

The Standard & Poor 500 Index, also known as the S&P 500, is one of the most famous indices on the planet. This is a weighted average index of stock prices of the 500 largest US companies.

In fact, this is a key indicator of the entire American economy and its condition is judged by it. S&P 500 Index (ticker SPX) is the most popular index in the world in terms of trading volumes after the Dow Jones Industrial Average.

There are entire funds, be it ETFs or pension funds, whose main task is to track the performance of the S&P 500, in which hundreds of billions of dollars are invested in trading.

NASDAQ Composite

This is the NASDAQ stock index (National Association of Securities Dealers Automated Quotations) - the largest electronic market in the United States, in which more than 4,000 companies and corporations participate.

It is one of the most liquid stock markets in the world. Ticker on the chart NASX.

Nikkei

The Nikkei index is like the Dow Jones Industrial Average, but for the Japanese. It averages out the performance of the 225 largest companies in the Japanese stock market.

Typical Nikkei representatives are Toyota, Mitsubishi, Fuji and others. Ticker on the chart NKY.

DAX

Stands for Deutscher Aktien Index - a German stock exchange index that includes 30 blue chips - the largest companies whose shares are traded on the Frankfurt Stock Exchange.

Germany is the most powerful economy in the EU, so if you are interested in the fate of the Euro, you should look beyond the DAX. The index includes companies such as Adidas, Deutsche Bank, SAP, Daimler AG and Volkswagen. Ticker on the chart DAX.

DJ EURO STOXX 50

The Dow Jones Euro Stoxx 50 Index is one of the key indices in the eurozone, reflecting the success of the largest EU companies. The index includes 50 enterprises from 12 EU countries.

Created by Stoxx Ltd., which is a joint venture of Deutsche Boerse AG, Dow Jones & Company and SIX Swiss Exchange. Ticker on the chart MPY0.

FTSE

Stands for Financial Times Stock Exchange, also known as “footsie” - an index of shares of the largest companies listed on the London Stock Exchange.

There are several varieties of it (this often happens with indexes). Let's say the FTSE 100 includes 100 companies, and the FTSE 250, respectively, the 250 largest companies in the UK. Ticker on the chart FTSE.

Hang Seng

The Hang Seng Stock Index for the Hong Kong Stock Exchange reflects changes in the prices of companies that are listed on the Hong Kong Stock Exchange.

The index includes the 50 largest companies with a capitalization of 58% of the total volume of the exchange. Ticker on the chart HSI.

RTS Index

Our native Russian index (ticker RTS), taking into account the 50 largest domestic companies whose shares are listed on the Moscow Exchange. By the way, it is calculated in US dollars. The list of companies whose shares are included in the index is reviewed every 3 months. The index appeared on September 1, 1995 and received a base value of 100.

The RTS index includes companies such as AFK Sistema, Aeroflot, Bashneft, Lukoil, RusHydro, UralKaliy, Tatneft and many others. There are also varieties of this index - RTS-2, RTS Standard Index and others, but the good old RTS index is the most popular.

As you can see, indices are a simple and very useful thing - they allow you to immediately obtain complete information about the state of not just a single stock market, but also the entire economy of the country as a whole. After all, the state of the largest companies is a key indicator.

The relationship between the stock and foreign exchange markets

Now let’s figure out whether it’s worth taking all these indices into account when working with currency pairs in FX/BO. Of course, it’s worth it - to determine general market trends on higher timeframes (remember).

In general, to be honest, when the stock market is on the rise, investors are more willing to invest in it, buying up the national currency for this. Which naturally leads to its strengthening.

If the stock market falls disconsolately, investors withdraw their money, converting it back into their currency and the national currency weakens. This is exactly the story that is happening here now; just look at the terrifying state of the RTS index, which has been falling since 2011.

However, there are two exceptions - the USA and Japan. The growth of the economies of these countries often leads to the weakening of their national currencies - such a funny paradox associated, however, with certain economic mechanisms.

Let's take a look at how the Dow Jones Industrial Average interacts with the Nikkei.

As you can see, the DJIA and Nikkei 225 index follow each other like a couple in love. At the same time, please note that sometimes the movement of one index anticipates the movement of another, which makes it possible to use such a miniature time machine for forecasts.

USD/JPY and Nikkei index

Let's see how the Japanese index affects the dollar/yen currency. Before the global financial crisis began in 2007, when the world's major economies fell quarter after quarter, there was an inverse correlation between the Nikkei and USD/JPY.

Investors were confident that the performance of the Japanese stock market directly affected the country's economic condition, so the rise of the Nikkei led to a strengthening of the Japanese yen. The opposite situation is also true: if the Nikkei falls, the yen is not doing well either.

And everything was fine until the financial crisis struck. That's when everything turned upside down. As a result, on the chart the index and the currency began to move in the same direction. Miracles, and that’s all: the Nikkei strengthens, the yen weakens and vice versa.

Nevertheless, the correlation remained more than transparent - its polarity simply changed.

USD/JPY and DJIA

Dow Jones index and dollar/yen, are they friends or so, spent the night together and “bye, I’ll call”? It would seem that there should be a clear correlation between them. However, judging by the graph, the situation is not at all so clear-cut. Although there is some correlation, it is not absolute.

It can be seen that after the financial crisis everything got mixed up again and there were periods when, instead of interaction, the chart was like hell.

Well, no one promised it would be easy. It's clear that we need to use technical and fundamental analysis, not to mention tools like , to get the most out of the indices.

EUR/JPY and stock indices

As we have already discussed, in order to buy shares of a company on the stock exchange, you need to exchange your papers for national currency. Let's take the German DAX index. In theory, if the index grows, then the euro also strengthens, because everyone is recklessly buying European shares. And such a correlation does exist, although it is not absolute.

What’s even more interesting is that EUR/JPY also has a correlation with other global stock indices. Not surprising, since the yen, like the US dollar, is considered a “safe haven” in times of economic crises. If the world economy is down and traders are in fear, they often take money out of the stock market, which causes the DAX and S&P 500 indices to fall. As a result, the price of EUR/JPY falls as traders buy the yen.

When everything is good, the girls are beautiful, and the sun is shining, investors pour money into the stock market, then the price of EUR/JPY rises. This is how correlation occurs.

Let's compare EUR/JPY with the S&P 500:

But with DAX:

We see, if not a mirror image, but quite a clear correlation. So be sure to take your favorite currency pair and see if it has any correlation with stock indices or other assets?

Let's say I took my favorite pair GBP/JPY and compared it with FTSE. What do we see? They are clearly interested in being together, what naughty people.

Well, this is from the category of “it’s better to see once.” Correlation of USD/RUB and Brent oil prices. Oil painting, almost Picasso: these guys will obviously kiss and get together, as has happened to them before.

Everything is interconnected

Correlation can be regarded as an additional indicator of the global market trend. If the indicators of two interrelated assets diverge, the trends of each are much easier to determine using technical analysis methods. And you already know what to do with trend lines.

Let's look at a few popular correlations between commodities and currency pairs.

• Gold up, dollar down . During economic crises, investors often buy gold for dollars, which is always in price.
• Gold up, AUD/USD up . Australia is the third largest supplier of gold in the world, so the value of the Australian dollar is largely related to the demand for gold.
• Gold up, NZD/USD up . New Zealand also produces a lot of goldfish.
• Gold up, USD/CAD down . Canada is the 5th largest gold supplier in the world. So if gold prices go up, USD/CAD moves down (because everyone is buying CAD).
• Gold up, EUR/USD up . Both gold and the euro are considered “anti-dollars”. Therefore, an increase in the price of gold often leads to an increase in the EUR/USD rate.
• Oil up, USD/CAD down . Canada is the world's largest oil producer, exporting more than 2 million barrels per day, mainly to the United States. If oil prices rise, the pair on the chart goes down.
• Interest on bonds up/national currency up . Everything is clear here: the more interest government bonds give, the more they are bought for national currency. As the demand for it grows, so does its exchange rate.
• DJIA down, Nikkei down . The economies of the US and Japan are very closely linked and go both up and down together.
• Nikkei down, USD/JPY down . Investors often choose the yen as a "safe haven" during periods of economic troubles.

The stock market, the state of which can be analyzed through indices, most directly correlates with currency pairs. By studying their interaction, you can often find situations where these data diverge in such a way that one indicator acts as a “time machine” for another. In this case, the important fact is not only the correlation itself, but also the change in its polarity from positive to negative and vice versa.

Finally, almost all brokers have the opportunity to work directly on these indices, both in BO and in Forex. Which can be used, even with correlations, even without them.

• Back:
• Forward:

In this topic, I present the results of my study of the dependence of various markets, in particular fRTS and S&P500, and also try to apply the information obtained to directly analyze trading results.

Let me make a reservation again, this is not a scientific article. I am an eternal student, like many others, I just find some of my research particularly interesting.

It’s no secret that our market “follows” Western markets, oil and much more. In general, in modern conditions of globalization, financial markets are much more strongly correlated with each other than they were, say, 20-30 years ago. It is traditionally believed that our Russia mainly depends on American indices, with dependence on oil in second place.
I am a system trader. And I became interested in how the behavior of my systems changes during periods when the Russian market decides to show character and stops following Western platforms. In other words, what is the relationship between the performance of my systems and the change in the correlation coefficient of the RTS futures and the S&P500 index.

But everything is in order. First, let's compare daily data. Correlation coefficients for daily changes (current close to previous day close) on average over the last year. I had to fudge the dates here and there so that most of the days would coincide.

Let me remind you that correlation only reveals the relationship between two data sets, but does not tell us “who is following whom.” The coefficient takes a value from -1 to 1. A complete lack of connection is 0.

The table shows that European markets are highly correlated with each other, are quite similar to the US market and have almost no regard for oil.

Russia “follows” the United States to a greater extent than European markets, and is least correlated with oil.

To be honest, this data is a little unexpected for me. I expected to see the coefficient value for the RTS and S&P more than 0.8. Well, such a weak correlation with Brent also seems strange. But it is interesting to look not just at the correlation coefficient of data for the last year, but at its dynamics.

Here I took several periods, as, for example, in calculating the moving average indicator. The 30-day period turned out to be more interesting for consideration (with a period of less than 15 days, strong outliers of values ​​appear, since on one particular day the markets can move in completely different directions).

Chart for Russia and S&P500 over the last year (30-day correlation):

The indicator shows how similar futures on the RTS index and the S&P500 index have moved in the last 30 days. In the first days of December 2011 - the behavior is on average for November. At the beginning of January 2012 - average behavior for December 2011, etc.

Thanks to the graph, it becomes clear why the correlation coefficient over the past year is not very high: at the beginning of the 4th quarter of the previous year, “similarity” was at the usual high level, but by the end of the year the coefficient dropped from almost a complete repetition of the actions of Americans to extremely average and not representative values<0,6. И очень интересно посмотреть, что же там было раньше:

Chart for Russia and S&P500 based on data from 09/01/2010. to 10/16/2012 (30-day correlation):

What benefit can be derived from all this?

I took the data from this system, namely, the coefficient of the average daily increment for the last 15 transactions. And compared it with the correlation coefficient of the RTS and S&P500:

It is clear from the graph that these two data series are not particularly similar, however, in some areas the coefficient graph moves with the change in the average daily increment. And of course it’s late. Conclusion: it is impossible to use the correlation coefficient to determine when a given trading system “shuts off”.

So what is it, I was counting everything in vain? (Did you read all this in vain? :)) I think there is still some benefit from this data. I suggest that the correlation coefficient can be used as a measure of the nature of the market. If the system begins to produce one loss after another, and at the same time the traditionally high correlation coefficient with America also begins to fall, this indicates that it is not the system that has broken, but the market itself has changed. If the market behavior has returned to its normal state, and the system continues to drain, then this is a reason to think...

What else can you check? For example, I'm going to look at the hourly charts of the RTS and Siploy from 17:30 Moscow time to 00:00 Moscow time. I will also be sure to check the dependence on the amers of my other systems. If you are also interested in this topic, with data for the last year. Use it :)

P.S. By the way, the graph of the correlation coefficient with oil changes along with the “similarity” to the S&P500, and is, presumably, a leading indicator for changes in the correlation coefficient of the RTS and the S&P500...
