The Fool has an article which notes that significant insider buying took place last week with Sigma Designs shares. From the article:
"Foolish newsletter associate advisor Stan Huber, in the April 2008 issue of Hidden Gems Pay Dirt. "I think Sigma is likely to trade close to $40 by the end of 2008," Stan said. "Management was willing to issue more equity at $46 some months ago, and that is usually a sign of where it considers the stock to be fully valued.""
