Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of renewable energy equipment manufacturer Satcon Technology (Nasdaq: SATC) jumped more than 11% in intraday trading as investors reacted to a public share offering.

So what: As a manufacturer of power conversion equipment for the renewable energy market, Satcon is long on promise and excitement, but short on financial results. The company's financial performance to date has consisted of a ledger full of losses and burned cash, so it's been necessary for the company to continually issue new stock to be able to keep the lights on. Today, Satcon announced that it issued an additional 9 million shares at a price of $3.90 per share.

Now what: If I were to guess, I'd bet that investors are celebrating the fact that the new shares weren't priced at too steep of a discount to yesterday's closing price. And while the new shares will allow Satcon to continue doing what it does for a while longer, the song still remains the same. That is, this company needs to find a way to put some black on its bottom line.
