A declining 30 week average is a major sign of weakness and could portend a Stage IV decline. That is when I used to transfer to cash in my university pension mutual funds. I already have done so.
Blog post: Day 27 of $QQQ short term down-trend; $SQQQ up 27% since Day 1 of $QQQ short term down-trend, beating more than 98% of stocks in major indexes.
Since I called the first day of the QQQ short term down-trend on January 6, the 3x inverse bearish QQQ ETF, SQQQ, has advanced +27%. SQQQ has advanced more than all but 5 of the 350 stocks in my recent IBD/MS watchlist, and all but one of the Nasdaq 100 stocks (ATVI) and the S&P500 stocks (ATVI again). I wish I had had the courage to hold SQQQ all of this time.
