LCK: pros love a stock that gaps up hard on a strong catalyst and draws in lots of retail, especially if the pros aren't initially holding as much as they'd like. They're forced to buy the spike if they believe the growth will follow, but not before they take from the retailers by using a big push down with their newly acquired spike shares. The gap is their trick as they know retail falls for it every time, so the pros have the psychological advantage, and the muscle to get the price to where they want it, knowing that they'll collect most retail shares bought into the spike.
