NEW YORK (

TheStreet

) --

Yahoo!

(YHOO)

was a big gainer in premarket trading on Tuesday, rising 3.68% to $16.35 following the company's strong

third-quarter

results on Monday.

Despite

underwhelming recent results

from tech heavyweights such as

Microsoft

(MSFT) - Get Report

and

Google

(MSFT) - Get Report

, the Internet giant comfortably beat Wall Street's top- and bottom-line estimates.

"Yahoo! had a solid third quarter, and we are encouraged by the stabilization in search and display revenue," said Marissa Mayer, the company's CEO. "We're taking important steps to position Yahoo! for long-term success, and we're confident that our focus on quality and improving the user experience will drive increased value for our advertisers, partners and shareholders."

Western Digital

(WDC) - Get Report

, however, was a big loser, tumbling 7.2% to $32.74. On Monday, after market close, the hard disk drive maker reported

strong fiscal first-quarter results

but offered weak guidance.

Shares of

Texas Instruments

(TXN) - Get Report

dipped 0.5% to $27.65 after the chipmaker released

third-quarter results

and investors responded to the firm's weaker-than-expected guidance.

The Dallas-based company cited ongoing weakness in the economy and the semiconductor market.

Facebook

(FB) - Get Report

, which reports its third-quarter results on Tuesday, slipped 0.47% to $19.23 before market open.

Shares of

Apple

(AAPL) - Get Report

, which is expected to launch the iPad Mini at a

press event

on Tuesday, dipped 0.57% to $630.4.

TheStreet

will be live-blogging the Apple event, starting at 12:30 p.m. EDT.
