Among leading gainers, cell phone game maker Jamdat Mobile Inc. rose 44.6 percent, to $24.22, after a strong quarterly earnings report and forecast for next year. Temporary personnel company On Assignment Inc. was up 21.4 percent to $4.88 after reporting decreasing quarterly losses and greater-than-expected revenues.
