The daily 10.4 stochastics indicator for the QQQ is now in oversold territory, at 9.91. That means that the Nasdaq 100 index is probably set to bounce within a few days. 
I wrote about HITK on September 19 when it broke out to a new all-time high. HITK still keeps rising, as shown by this weekly chart. But it is dangerous to buy a strong stock in a market down-trend.
