The GMI declined to 5, as only 63 of the 142 stocks in my universe that hit a new high 10 days ago closed higher than they did 10 days ago. Stocks hitting new highs should be moving up in a strong market. When breakouts fail it can be an early sign of a weakening market. However, there were 290 new highs in my universe of 4,000 stocks on Monday. 60-69% of the stocks in the Nasdaq 100, S&P 500 and Dow 30 indexes advanced. Monday was the 61st day in the current QQQQ up-trend. The GMI-S, a measure of short term strength in four indexes, rose to 81 because all 4 indicators for the QQQQ are now positive. The Nasdaq 100 stocks are leading the market up. 66% of the IBD 100 stocks from 10/16 rose and 11 stocks hit a new high (PRFT,SIM,DRIV,PHLY,HXM,INFY,AXR,VIP,ICLR,ADS,AEOS).
