I thought u go with the wave. Here's a fact and not a guess, twitter will pull back and every major trader knows this it's just once some more shares become avail it will happen, but then I think it is a good buying opportunity. Fb will move two steps forward and one step back from here more or less, that will be the trend or "wave". I like twitter as a company but as a stock it needs to pull back and show good management execution for just a few quarters prove itself and show that it made smart moves with its new capitalization and the stock comes back to 44 and on to 50- with that said I don't think it pulls back as far as fb because there are less shares but i would gather that it goes down to 38 but prob not much more. I think as long term investments both are good but I def would not short fb and long twitter as the companies r in different innings of the game.
