Many traders lose their initial capital on stock exchange. This isn’t always because of inefficient stock buying and selling strategy speculate participants frequently ignore a number of risk management rules or don’t follow them whatsoever. Loss trades are members of work with every trader and it’s important to manage possible reduction in each trade. I won’t talk about necessity to put together stop-loss and restrict amount of each trade by a few percentage worth of your buying and selling balance. The assumption is that it’s an axiom for each trader. In the following paragraphs we wish to know how the stock correlation could make the danger management more efficient.
Stock Correlation is really a floating number between -1 and 1. It shows amount of similarity between two stocks within their cost changes. “1” means the stocks are absolutely identical within their cost changes. Practically 1 isn’t achieved. A share has correlation 1 with itself. “-1” implies that shares relocate absolutely opposite directions. It’s also merely a theoretical value, but stocks might have correlation that converges to -one in practice. “” implies that no any dependencies between two shares. “” is extremely rare, almost theoretical value since it is impossible to locate absolutely independent shares. All shares rely on entire market mood and as a result always correlate to one another.
Just how the correlation pertains to risk management? Traders tend not to trade just one stock. They keep opened up positions for many stocks. This number of stocks is generally known as “buying and selling portfolio”. And this is an excellent practice since it is uncommon to take a position the money in just one stock.

Only within this situation, once the correlation between two shares within the portfolio closes to , you’re hedging your assets. Opposite to low correlated stocks, high correlated stocks, with correlation value near to 1, relocate exactly the same direction the majority of the some time and you lose advantages of portfolio usage. Such situation could be in contrast to purchasing one tell the summarized portfolio volume. But there’s a bad risk to get rid of the money when the share drops lower considerably. Therefore we can conclude that certain have to check correlation values before adding new stock within the buying and selling portfolio.
