NEW YORK (TheStreet) -- Dell(DELL) shares climbed 5.78% to $13 in premarket trading on Tuesday as buyout speculation again swirled around the beleaguered tech giant.

Bloomberg reported on Monday that the No. 3 PC maker, once the world's largest, is in buyout talks with private-equity firms.

Dell hasn't yet responded to TheStreet's request for comment on this story, although the company's shares surged on the media report, closing up 12.96% on Monday.

The Texan firm was also the most active premarket Nasdaq stock on Tuesday on share volume of 1,158,531.

Facebook(FB) , which hosts a major press event at its headquarters in Menlo Park, Calif., on Tuesday, was another gainer in premarket trading.

Shares of the social networker rose 1.14% to $31.30 before market open on Tuesday, after closing down 2.44% on Monday. Facebook was also one of the most active premarket Nasdaq stocks on share volume of 296,165.

There has been plenty of speculation about Facebook's likely announcement, with rumors swirling around possible search engine news or a streaming video deal with Netflix(NFLX) .

Mellanox(MLNX) was another gainer on Tuesday, rising 4.81% to $52.94 after UBS upgraded the storage specialist to buy from neutral and raised its price target to $65 from $56.

"We believe the risk-reward for Mellanox is compelling," wrote UBS analyst Steven Milunovich, in a note released on Tuesday. " We are above consensus for 2013 and believe the stock downside is limited."

The network infrastructure specialist's shares rose 8.74% to $11.07.

Apple(AAPL) , which saw its shares lose 3.5% during Monday's trading, crept up 0.39% to $503.7 on Tuesday.
