need to revise the s & p earings to be a adjustable (5, 10, 20, 50)
The 50 day moving average for s&p earnings is too long of a period.
It lags the market by too many days. You need an S&P earnings that is adjustsable 5,10, 20, 50 - would be much much better as a gauge to
see the trend of the stock market which follows earrnings almost exactly.
