If I were to open a market position on TWTR, is the stock price still hyped and would it be a good time to short to stock?
Looks like the stock could reverse it's uptrend from the previous months and reach the 10-15 range again.
If you want to short something like this, take a look at put options instead as your liability is explicit.
That depends. How confident are you that you have information, or a source of information, that has not been priced in by the market yet?
