I started shorting SPLM after the volume spikes in March. The price ran near $3.70 and the stock (due to an apparent old fashioned snail mail promotion) began to look ready to roll over. Shares were sometimes available (you actually had to short pre-market to get any). Since then the stock has rebounded several times and I was able to get shares on some of those occasions. The stock pulled back and then bounced four different times. The possible return on each drop was +40% +30% +50% +50%. On a side note, although I never went long this stock, tremendous profits could have been made by covering shorts and going long for the rebound each time. The trading strategy is called "playing the bounce" and with a good eye for level II you can be a success at it (I seem to have more patience on the short side).
