Facebook stock closes up for 4th straight day

NEW YORK (AP) -- Facebook's stock has had its fourth consecutive day of gains.

The stock increased 50 cents, or 1.6 percent, to close Tuesday at $31.91. That's still down 16 percent from Facebook's IPO price of $38. But now there are as many up days as down days for the stock -- 11 each.

Facebook began trading on May 18. Facebook's stock has traded as low as $25.52 since the IPO.

Investors have been concerned about its ability to keep increasing revenue and make money from its growing mobile audience, though many analysts hold positive long-term opinions.
