Quote from dougcs:
One of the extra things I'm doing is watching JH stocks that also have a high short interest ratio (SIR) defined as shares short/float. BOOM has an unusually high SIR, about half its float.
Sometimes these stocks really pop if a short covering rally gets going as the shorts get scared and buy to cover.
We will see how it does today.

ps-Marty, is this something that your Spyderfilter.jar could calculate ?
