Research In Motion, Yahoo!: After-Hours Trading (Update 1)

Updated from 6:02 p.m. ET for latest share prices, information about Research In Motion, Xoma.

NEW YORK ( TheStreet) -- Shares of Research In Motion ( RIMM) slumped in Tuesday's extended session after Samsung said it's not interested in acquiring the struggling Blackberry maker.

James Chung, a spokesperson for Samsung, was quoted by Reuters as saying: "We haven't considered acquiring the firm and are not interested in (buying RIM)."

The stock had gained 8% in the regular session to close at $17.47 with volume reaching nearly 60 million, nearly three times the issue's trailing three-month daily average of 21.6 million, following speculation on a blog that Samsung was targeting a deal for Research In Motion.

In after-hours action, the shares gave back 97 cents, or 5.6%, to $16.50 on volume of around 650,000.

Linear Technology

Shares of Linear Technology ( LLTC) rose in late trades Tuesday after the chip maker topped Wall Street expectations with its latest quarterly results and gave an above-consensus revenue view for its fiscal third quarter.

Milpitas, Calif.-based Linear reported non-GAAP earnings of $104.9 million, or 45 cents a share, for its fiscal second quarter ended Jan. 1 on revenue of $294.3 million. The average analysts' estimate was for a profit of 39 cents a share in the latest three-month period on revenue of $294.3 million.

For its fiscal third quarter ending in March, Linear forecast sequential revenue growth of 4%-8%, which implies a range of $306.1 million to $317.9 million. Wall Street's current estimate is for revenue of $302 million in the quarter.

The stock was last quoted at $32.20, up 7.8%, on volume of more than 75,000, according to Nasdaq.com. Based on Tuesday's regular session close at $29.87, the shares were down more than 15% in the past year, scraping a 52-week low of $25.41 on Aug. 9.

Linear also said it's increasing its quarterly dividend by 4% to 25 cents a share from 24 cents a share. That brings the forward annual yield on the shares to 3.3% before factoring in the after-hours move.

"This was an encouraging quarter in a difficult global economic environment," said Lothar Maier, Linear's CEO, in a statement. "We met the mid point of our guidance and we believe that we are at an inflection point in our business. Bookings, which started slowly, strengthened in December and continued strengthening in January."

Wall Street was skeptical on Linear ahead of the news with 14 of the 23 analysts covering the stock at either hold (11), underperform (2) or sell (1) and the 12-month median price target at $32.50.

Yahoo!

Shares of Yahoo! ( YHOO) got a boost after the bell following news that co-founder Jerry Yang has resigned from the company's board.

Yang has also resigned from the boards of Yahoo! Japan and Alibaba Group. He cited a need to "pursue other interests outside Yahoo!" for the decision.

Is Yang Really Gone From Yahoo!

"My time at Yahoo!, from its founding to the present, has encompassed some of the most exciting and rewarding experiences of my life," Yang said in his letter of resignation, according to a company statement. "As I leave the company I co-founded nearly 17 years ago, I am enthusiastic about the appointment of Scott Thompson as Chief Executive Officer and his ability, along with the entire Yahoo! leadership team, to guide Yahoo! into an exciting and successful future."

The news could be a sign that Yahoo! is getting ready to make a deal of some sort. The company has been examining its strategic options for months now, and media reports of what it plans to do run the gamut between the sale of the whole company to the divestiture of certain assets.

Scott Thompson was named to the CEO role on Jan. 4, replacing Carol Bartz, who was ousted in September. Thompson previously served as president of PayPal, eBay's ( EBAY) electronic payments business.

Yahoo! shares were last quoted at $15.89, up 2.9%, on volume of 3.1 million, according to Nasdaq.com. The stock is down roughly 6% in the past year with revenue growth stalled.

Also active in Tuesday's extended session were Cree ( CREE), whose shares lost more than 5% to $22.10 on volume of more than 800,000 after the LED company disappointed with its quarterly report; and Xoma ( XOMA), whose stock rose more than 8% to $1.82 on volume of less than 20,000 after the company said it's agreed to acquire the U.S. rights to Aceon, a treatment for hypertension, and that it's establishing commercial operations to sell the product.
