Recently I've been fascinated with short sellers. Specifically the daytrading types. While there are a lot of big talking lambo owning con man types like Madaz, Verma, Sykes, Dux, Grittani, et al. Some of the strategies that they use have some weight, especially if they apply serious statistic analysis to back their trades ala Dux. I tried to search the web and even on ET but surprisingly come up short on information. Searching for FRD and GUS don't show up so they are not popular terms. I'll bet a lot of long time ET guys don't even know what those acronyms even mean. Some of the vernacular and strategies surrounding short selling daytraders - Gap Up Short (GUS) or First Green Day (FGD). Stock goes parabolic with large volume. Typically low float small caps that churn 50x, 60x, 100x volume than the float. - First Red Day (FRD). After the big GUS/FGD, the first day when the bubble bursts. Consider to be a high percentage play as stocks that are multi day runners will deflate rapidly resulting in >50% drops. - Dollar block analysis. Determing average consolidation price typically using VWAP on large volume days to determine if a small cap has exhausted its pump. - Market maker manipulation. As these are low float stocks, some as low as 2 mil float, some MM with large share size have great control over how strongly the pump up will be and also how sharply the drop will be. Continually pushing prices higher or lower. - Death candle. A big volume flush on the 1 or 2 minute chart. Typically signifying that a turning point is coming ie the pump is done. - Gamma squeezing. Using options to force MMs to buy or sell shares in order to be market neutral. This strategy gained spotlight when AMC/GME went parabolic. Simple short squeezing shares wasn't the only catalyst to make AMC/GME go supernova since short selling firms like Melvin Capital will quickly unwind their positions. Gamma squeezing proved effective in continually pumping even fairly larger cap stocks like AMC. - Share dilution. Part of the small cap game when pumping stocks especially biotech ones is to then have a secondary shelf offering. A way for cash strapped small caps to stay alive. So sketchy headlines like a successful cancer saving phase 3 trial helps pump up stock prices as eager greedy daytraders pile in.
