Shares in Diodes Inc. jumped nearly 8 percent Thursday after the semiconductor maker raised its third-quarter revenue guidance.

The Westlake Village-based company said that it now expects as much as 10 percent growth for the quarter but didn’t give any specific reason.

Diodes said it expects revenue to rise by between 8 percent and 10 percent compared to the same period a year earlier, meaning sales could reach as high as $102 million versus the $93 million reported last year.

Wall Street is expecting third-quarter sales of $103 million, according to Thomson Financial.

This is an increase from the company’s guidance issued in August, of growth between 6 percent and 9 percent.

Shares in Diodes rose $2.27, or 7.8 percent, to $31.41 in afternoon trading Thursday on the Nasdaq.
