A reversal is just anything that's a surprise. It's a way of keeping the audience interested.NEW YORK ( TheStreet) - Every week I run a screen on my list of over 1,000 ETFs/ETNs to identify which areas of the investable landscape are showing extreme movement. The idea behind doing this is to get a sense of what opposite ends of the performance spectrum may be signaling about investor sentiment going forward. Take a look below at those ETFs furthest above (extreme winners) and furthest below (extreme losers) their respective 20-day moving averages.
