Green Hornet will be halted tomorrow for the weekend...until adjusts happen on Sunday. So if you want to sell it... you should do it before it halts, if you feel it will not adjust higher than it's current price. If you feel it will adjust UP, then you can hold it for continued profits on the stock when it adjusts.
Beware of anyone who tells you when to buy or sell as stock as they may be trying to manipulate the stock price (which is against the Code of Conduct).
Movies that open each week, will usually have a lot of movement in price prior to when they halt due to players jockying for how they want to hold the stock.
Only you can decide how much of a profit or loss you're willing to accept before you sell or cover a stock.
