By watching the asks for a thinly traded stock they may be able to scoop up anyone who has in place a stop-loss. I remember a few years ago when EPMN was trading in the $3.00 (?)range that within minutes of the end of trading the price suddenly went down to $.28 where, as I recall, 25,000 shares were grabbed. (I may have my facts wrong, but you get the picture.)The next day it was back up to normal pricing. The lesson? Never put in place a stop-loss for a stock like IDMI.
We may see something like this happen in the next few weeks.
