Real Goods Solar (NASDAQ:RSOL)

Ok. So I checked Real Goods Solar out.

RSOL has a nice little business model to grow faster than their organic growth rate by buying small regional companies to become a leading US distributor/ implementer for residential and small commercial solar installs, and for us us old hippies and children of hippies, Real Goods is an awesome brand.

On the fundamentals, current PE is 9. They have $15m in cash per last 10q. Growing earnings at 15% yoy per last 10q. Short interest is at an annual low relative to daily volume. Doing the math, that's about $4.34 per share, discounting the cash by 50%, $5 if you fully value the cash.

Last, a major shareholder - who acquired stock by having her company be acquired by Real Goods (guess she was disgruntled since there a lawsuit that was thrown out etc etc) - finally ran out of stock to dump this last Spring. She sold off about 2.6m shares - or about 1/3 of the current float - over the course of the previous 12 months or so.

Not looking for fu money out of this stock, just reasonable value. There's been ridiculously low volume, so the stock's been swinging all over the place. I can live with that. But there's also been continued downward pressure which I'm not getting. Can somebody provide insight into what's going on here?
