Some institutional favorites, most significantly Amazon, couldn’t rally to save their lives yesterday. Our #1 bellwether was down almost $20 at the intraday low, causing the entire stock market to sag. Google arguably looked even worse, since its $24 plunge exceeded several prior lows on the intraday charts. If these stocks and a few other Nasdaq world-beaters can’t turn things around on Tuesday, it’s going to pull the broad average down hard before the week ends.
