A 67 percent increase in profits drove up shares of Torrance-based computer seller PC Mall in early trading Thursday.

Earnings for the second quarter were $1.36 million or 11 cents a share, up from $815,000 or 6 cents a share in the same period last year. Revenue for the quarter was $317 million, up from $261 million.

“Our year-over-year growth rate significantly accelerated from the first quarter,” Chief Executive Frank Khulusi said in a statement. “We believe that this growth was driven by both an improving demand environment and by the investments that we have been making in our businesses.”

Specifically, Khulusi cited recent acquisitions that complement PC Mall’s main business as an Internet reseller of information technology hardware.

In late morning trading, PC Mall gained 24 cents or 5 percent to $4.50 per share on the Nasdaq Stock Exchange.
