The NASDAQ Biotech Index ($ NBI) is currently evolving in a well-marked down channel formed by DR1 and suppoty DS1 resistance. In a few days, sellers should test the very strong resistance of $ 3200. This resistance was broken sharply during the fall of the end of 2018, which made it very fragile. The most likely scenario (72%) would be that the resistance of $ 3200 cracks to let sellers get the weekly support of $ 2,800 (WS2). A very interesting trade short offering a risk / reward greater than 2 can be opened on the $ NBI. The target will be set at $ 2,800 and the stop-loss is set to the current value of the 50-day moving average. The trade yields 388 points, a little more than 12%.
