There are several posts regarding Sigma Designs today (here, here and here). The best summary of the company's prospects comes from the Fool's article:
"So the stock took a 16% fall on Friday and is down a staggering 75% from a December peak of $72.17 per share. But the company has $138 million in cash equivalents with no debt, just released a significantly faster version of its flagship product, and sees new markets opening up in early 2009. Exciting business and a massive discount on the stock -- what's not to love?"
This stock is still a MF Rule Breakers recommendation.
