Here are the biggest percentage gainers and losers in pre-market trading among companies with a market cap between $50 million and $750 million:

Biggest percentage gainers:

• Fuel Systems Solutions, Inc. (Nasdaq:FSYS), up 19% after reporting first-quarter results after Monday’s close that beat the street and raised full-year revenue guidance.
• Kenexa (Nasdaq: KNXA), up15% after the global provider of talent acquisition and retention services reported first-quarter earnings after Monday’s close that trumped the consensus on Wall Street, while revenues met. The company also issued full year guidance above analysts’ estimates and second-quarter revenues above the Street.
• Ultrapetrol (Bahamas) Ltd. (Nasdaq:ULTR), up 13% after the industrial transportation company reported first-quarter results Monday evening that beat the consensus on Wall Street. The small cap attributed the robust results to strong demand in all of its main lines of business.

Biggest percentage losers:

• ShopNBC (Nasdaq:VVTV), down 10% after the 24-hour TV shopping network said after Monday’s close that it expects to report a decline in first-quarter revenues below the consensus on Wall Street, as the company grappled with a difficult consumer economy and a slowdown in discretionary spending.
• Hoku Scientific, Inc. (Nasdaq:HOKU), down 7% after reporting fourth-quarter results this morning that fell short of the consensus view on Wall Street.
• Comverge, Inc. (Nasdaq:COMV), down 5% after reporting a first-quarter net loss that was wider than Wall Street expected, but narrower from the year-ago quarter.
