- 1. Diversty or be Sued! An investor with a stock portfolio worth several hundred thousand dollars sued his broker because lack of diversification in his portfolio led to poor performance (low returns) The table below gives the rates in percentages for the 39 months that the account was managed by the broker. An arbitration panel composed these returns with average of the Standard and Poor's stock index for the same period. Consider the 39 SRS monthly returns the broker would generate if he managed the account forever. Are these returns compatible with a population mean of .95%, the S&P 500 averaged over 35 years?
