What's better than momentum? Mo' momentum.

Let's take a closer look at five of this past week's biggest scorchers.

Imperial Sugar was the market's sweetest victor, nearly doubling after revealing that it's in the late stages of exploring the potential sale of its valuable interest in Wholesome Sweeteners.

O'Charley's is serving up an exit strategy to its shareholders. The restaurant operator agreed to be acquired by a title insurance for $9.85 a share, a 42% premium to where the stock is now.

Guidance Software shareholders were glad to unravel last week's mystery. The provider of forensics and investigations software took off after delivering better-than-expected guidance for the year ahead. Guidance is eyeing a profit between $0.35 and $0.42 a share on $126 million to $131 million in revenue for 2012. Analysts were targeting net income of $0.30 a share on $113.9 million in revenue.

DryShips turned in a strong performance on encouraging news out of Greece. The Greek dry bulk shipper has been one of the market's more volatile stocks in recent months. Between the cyclical nature of its industry and the turmoil in Greece, that's likely to continue.

Trina Solar and several of its solar energy peers rallied last week on reports of strong global demand. The sector had a rough 2011 for a myriad of reasons, but the prospects for key players are starting to brighten.
