UPDATE - Massive gap down on Jan earnings on very high volume (historically accompanies poor price). But after substantial decline to date, could it signal exhaustion gap or capitulation?
Key to note now is that if the price continue to drift lower, it should be on substantially low volume or actually attempt to rally and then fall on lighter volume and retest low or make higher low. That could suggest the selling is over and possible long position could be considered with defined stop loss. Better to trade this bu using directional out of money with Oct-Dec time view for recovery but far out of the money to keep the risk low which should pay well even if we only bounce for 50%-61.8% retracement of the overall decline. Or similar Option spread trade, depending on your view and acceptable risk.
