By the end of the Specialization, you will be able to create long-term trading strategies, short-term trading strategies, and hedging strategies.To be successful in this Specialization, you should have a basic competency in Python programming and familiarity with pertinent libraries for machine learning, such as Scikit-Learn, Stats Models, and Pandas. You should have a background in statistics (expected values and standard deviation, Gaussian distributions, higher moments, probability, linear regressions) and foundational knowledge of financial markets (equities, bonds, derivatives, market structure, hedging).By Anupriya Gupta Pairs trading is supposedly one of the most popular types of trading strategy. Hsbc trading strategien. [[In this strategy, usually a pair of stocks are traded in a market-neutral strategy, i.e.it doesn’t matter whether the market is trending upwards or downwards, the two open positions for each stock hedge against each other.The key challenges in pairs trading are to: Statistics play a crucial role in the first challenge of deciding the pair to trade.

The pair is commonly chosen from the same basket of stocks, for instance, Microsoft and Google (technology domain) or ICICI & Axis (Indian Banking) or Nifty Index and MSCI index (market indices).Among each domain, there are thousands of pairs are possible.The best ones are those which are based on mathematical or statistical tests. Dr. beate handel halberstadt. We will learn about two statistical methods in the next section of pairs trading.Though not common, a few Pairs Trading strategies look at correlation to find a suitable pair to trade.Correlation is quantified by the correlation coefficient ρ, which ranges from -1 to 1.

The correlation coefficient indicates the degree of correlation between the two variables.The value of 1 means there exists a perfect positive correlation between the two variables, -1 means there is a perfect negative correlation and 0 means there is no correlation.A perfect positive correlation is when one variable moves in either up or down direction, the other variable also moves in the same direction with the same magnitude while a perfect negative correlation is when one variable moves in the upward direction, the other variable moves in the downward (i.e. The correlation coefficient for the two variables is given by Correlation(X, Y) = ρ = COV(X, Y) / SD(X).

SD(Y)where, cov (X, Y) is the covariance between X & Y while SD (X) and SD(Y) denotes the standard deviation of the respective variables.If the correlation is high, say 0.8, traders may choose that pair for pairs trading.This high number represents a strong relationship between the two stocks. So if A goes up, the chances of B going up are also quite high.Based on this assumption a market neutral strategy is played where A is bought and B is sold; bought and sold decisions are made based on their individual patterns.Just looking at correlation might give you spurious results. For instance, if your pairs trading strategy is based on the spread between the prices of the two stocks, it is possible that the prices of the two stocks keep on increasing without ever mean-reverting.Spread = log(a) – nlog(b), where ‘a’ and ‘b’ are prices of stocks A and B respectively.For each stock of A bought, you have sold n stocks of B. Now, both ‘a’ and ‘b’ increases in such a way that the value of spread decreases.This will result in a loss since stock A is increasing at a rate lower than stock B and you are short on stock B.Thus, one should be careful of using only correlation for pairs trading.

Let us now move to the next section in pairs trading basics, ie Cointegration.The most common test for Pairs Trading is the cointegration test.Cointegration is a statistical property of two or more time-series variables which indicates if a linear combination of the variables is stationary. The two-time series variables, in this case, are the log of prices of stocks A and B.
