You have to know yourself with respect to ARIA, i.e. know whether you are a trader, investor, or both, meaning that you trade the stock frequently, bought it and will hold it until you get out, or trade part, hold part.
I suspect that you, like me, and probably most of the longs on this board, buy and hold as investors. Unless you are a gifted trader, trading this stock exposes the risk you point out, missing the moves, or part of it.
The current trading in the stock is near meaningless. A few hundred thousand shares bought or sold pushes us 2, 3 4% in a blink. We are shorted, traded in a near cyclical fashion. Few can compete with trading by a coordinated pack of attacking hyenas on some massive trading floor.
News and meaningful, sustainable revenues and earning will mow us, in that order. So if you can, hold on like you have in the past, and sell at a point you determine to be your sell point.
Selling is hard, sell bits here and there once the big pop occurs. Pay yourself. My advice.
