Trading sideways with sudden drop in volume probably translates to MM's and "big money" having the price right where they want it for now with push/pull fluctuations provided by retail.
Just waiting for catalyst(s), news, events, buyout, financials, etc for the train to leave for the next station... (or "big money" to get a wild urge or catch wind of a rumor)
They drive the train, we just ride it til our stop shows up. :-)
