What are the Future 90-Day S&P 500 Performance Statistics shown in the Members Area?
Since our ‘Weighted Composite Index’ leads the S&P 500 by over 140 days, we have found it useful to measure how the S&P 500 has performed historically over the 90-day period that immediately followed each ‘Weighted Composite Index’ date. The data collected by this process allows us to update Members daily on the risk associated with the S&P 500 over the next 90 days. The daily updates include the current 91-Day Growth Index, the average 90-day performance of the S&P 500 following a day when our 91-Day Growth Index was within a point of the current level, the standard deviation of those 90-day S&P 500 returns, and finally the probability (based on those historical statistics) that the S&P 500 will give a net positive return over the next 90 days. This data should allow our Members to assess for themselves the risk associated with their market investments over the next 90 days.
