Stock Price Correlation Analysis:

Linear correlation is a statistical analysis tool that can help to show if a relationship between 2 parameters exists. The correlation value is called the correlation coefficient and ranges from -1 to 1. A value of 1 means there is perfect correlation. -1 means perfect anti-correlation. And, a value of 0 means no correlation exists between the 2 parameters.

The default parameter used in the analysis on aistockcharts.com is the daily percentage change in stock prices for the last 60 days. A correlation coefficient value of 0.8 means that the daily percentage stock price changes between 2 stocks has shown a strong correlation. In other words, over the last 60 days the stock prices changed by about the same percentage each day. Keep in mind that correlation may or may not be significant and does not necessarily represent causation. See tool #6 below for a significance test.

HYPOTHETICAL PERFORMANCE RESULTS HAVE MANY INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW. NO REPRESENTATION IS BEING MADE THAT ANY ACCOUNT WILL OR IS LIKELY TO ACHIEVE PROFITS OR LOSSES SIMILAR TO THOSE SHOWN. IN FACT, THERE ARE FREQUENTLY SHARP DIFFERENCES BETWEEN HYPOTHETICAL PERFORMANCE RESULTS AND THE ACTUAL RESULTS SUBSEQUENTLY ACHIEVED BY ANY PARTICULAR TRADING SYSTEM. ONE OF THE LIMITATIONS OF HYPOTHETICAL PERFORMANCE RESULTS IS THAT THEY ARE GENERALLY PREPARED WITH THE BENEFIT OF HINDSIGHT. IN ADDITION, HYPOTHETICAL TRADING DOES NOT INVOLVE FINANCIAL RISK, AND NO HYPOTHETICAL TRADING RECORD CAN COMPLETELY ACCOUNT FOR THE IMPACT OF FINANCIAL RISK IN ACTUAL TRADING. FOR EXAMPLE, THE ABILITY TO WITHSTAND LOSSES OR TO ADHERE TO A PARTICULAR TRADING PROGRAM IN SPITE OF TRADING LOSSES ARE MATERIAL POINTS WHICH CAN ALSO ADVERSELY AFFECT ACTUAL TRADING RESULTS. THERE ARE NUMEROUS OTHER FACTORS RELATED TO THE MARKETS IN GENERAL OR TO THE IMPLEMENTATION OF ANY SPECIFIC TRADING PROGRAM WHICH CANNOT BE FULLY ACCOUNTED FOR IN THE PREPARATION OF HYPOTHETICAL PERFORMANCE RESULTS AND ALL OF WHICH CAN ADVERSELY AFFECT ACTUAL TRADING RESULTS. THE RISK OF LOSS IN TRADING STOCKS CAN BE SUBSTANTIAL.

Stock trading is speculative and a substantial risk of loss exists. Past performance is not necessarily indicative of future results.
