These are judgement calls I personally never want to face since the best answer should've been buy yesterday and the days & weeks before that, just as all the other longs had done.
Nevertheless, I personally believe that the stock is a little inflated at its current price level. Will it go down? Yes, IF no news comes out. We're trading at a premium because of the anticipation of something big, something soon. It's as simple as this: If you think news is coming out soon & you think other people think so too, buy now. If you think news is not coming out soon & other people think so too, buy later.
