Shares of Intel Corp. INTC advanced 3.31% to $21.84 Friday, on what proved to be an all-around mixed trading session for the stock market, with the Dow Jones Industrial Average DJIA rising 0.09% to 42,063.36 and the S&P 500 Index SPX falling 0.19% to 5,702.55.

Intel stock closed up 3.3% on the news, after jumping as much as 9.5% when the story first broke. Qualcomm closed down 2.9% after sinking 6% earlier, showing Qualcomm investors didn't like the idea of a tie-up between the two chip giants.

A late-Friday report that Qualcomm recently made a "takeover approach" to Intel sent the latter company's shares higher.
