I haven't followed up with them, but I went to an Xmas party on Thursday night, and got into a conversation they initiated about stocks/investments. These were two guys that are both quite wealthy (and I KNOW one of them recently received a half mil+ inheritance). After listening to them babble about their investments, I mentioned PTSC and the current state of affairs. They were appropriately intrigued, and actually wrote down the symbol on napkins. Of course I strongly recommended they do some serious DD before doing anything, but emphasized that time may be very short, so don't dilly-dally.
So, allowing time for DD Friday morning, at least some of our action Friday afternoon may have been one or both of these guys, having done DD to their satisfaction, jumping in.
It was the first time in a very long time that I've recommended any stock. Due to past experience, I provided all the caveats and warnings I felt necessary to feel "comfortable" when suggesting they take a look.
Word of mouth could be all the explanation needed for Friday's action, IMO.
But I KNOW nuttin'!
