Exponential Moving Average Stategy

If the 15-week EMA stays less than the 40-week EMA on the S&P 500 by Friday's close, a major bearish signal will be given.  This is the same indicator that flashed a sell signal back in January 2008.  (I believe we all know the consequences of that superb sell signal on maintaining your financial health.)  Therefore, my strategy will be to use any market strength to add to my inverse ETFs, such as DXD, SDS, QID, and TWM.
