speculating on a stock halt tells a lot about your poor understanding of this market, because that won't happen here
if you plan to short it, fine, but let's be objective and realistic with your statements.
It is obvious that there's money to be made both sides, but you don't have a crystal ball to guess the peak price, and unless you have tones of cash to cover an eventual margin call, you could get burned big time if you short RAYS too early.
technically, a short seller has more risk than a long, since you can lose much more than your original capital, while a long can't lose more than a 100%
good luck with your trading decisions.
