The GMI remains at one. Only 24-34% of the stocks in the Nasdaq 100, S&P 500 and Dow 30 indexes advanced on Thursday. There were 54 new highs and 77 new lows in my universe of 4,000 stocks. Only 43% of the stocks in my universe closed above their 10 week averages. 
The real reasons behind the markets plunge may be yet to be disclosed. Time to stay in cash.
