Nasdaq is down 2.5% today and the ATR trend line has triggered intraday Sell Signals on multiple time frames. QQQ has also triggered short-term Sells and a close below $325.00 would be very bearish (currently $327.55). There is so much potential for a deep sell-off this summer that its time to establish initial index put positions. Intermediate Term Sell Signal: QQQ (327.55) Option: Jun 18th $315P (6.60-6.65)
