New holder filed today, Renaissance Technologies. This is probably the single most successful HF of all time, all based on computer algo's, so their computers see something here (google them). Would rather it be a fundamental guy, that I think would give other investors confidence/cause more fundamental guys to do the work, and would qualify as one of my "squeeze extenders." But this is at least corroborative of something has changed here in the way this stock is trading, so may not bring new money to name to extend a squeeze, but I think big point that a low volume squeeze may be beginning. Again, we shall see...

This is an article that talks about Renaissance cutting back... maybe they are selling more? Are you certain they were buying?
I subscribe to a service that sorts through all the 13-F's, but if you want confirmation (I'm not lying by the way), you can go to sec gov, filings, search company filings, click on company or fund name link, enter "renaissance technology", then click on latest 13-F
