There have been multiple objective short entries on QQQ since the July top with the first highlighting what I identified as a ‘blow-off top’ back on July 18th (also highlighting the blow-off top in MSFT, AAPL backtesting the primary uptrend line which it recently broke below, and subsequently, the bearish engulfing candle & divergent high that SPY put in on on July 27th:

Again, the case to short or add to existing (additional sell signals on the magnificent 7, semiconductor sector, etc..) was highlighted incrementally & fairly steadily as the bearish technical developments in both the equity markets as well as Treasuries yields & crude oil (i.e.- the re-emergence of inflation) continued to emerge.

QQQ topped on July 19th (end of that blow-off top) with SPY topping on July 27th.
