This video is for everyone who sees a stock at new highs and immediately thinks it should be shorted. That is not a good idea. Stocks that are at 52 week highs tend to keep going up. I like shorting things that go up, but only if they go up a lot very quickly (like 100% in three days) and then I will only short once they start to fade (I particularly like to short once they go red on the day in the afternoon after fading gradually).
