Someone called this shakeout a while back, I don't remember who but it's not anything unusual even with a catalyst as big as this. In this case it's reminiscent of a bio pharma or biotech event with weak hands getting cold feet and bailing. Classic buy the rumor, sell before the news move. Zion's a perfect target for this type of short attack being a microcap and a wildcat play. That being said it's now the perfect setup for an epic squeeze if Zion delivers the goods. This could run in the hundreds of percents in the first pop.
