The lead dog (Nasdaq 100) has now followed every other major stock index to print a daily close below the critical “flashpoint” support levels & with Facebook making the expected post-earnings face-plant, with the stock closing down nearly 9% in the after-hours session following their earnings report & conference call, we now have about as good as a sell signal can get on the US stock market. Some of the likely key support levels/downside target shown here with some specific price targets & possibly some official swing short trades on the broad market tracking ETFs to come as soon as tomorrow.
