Sina, Rambus, Shutterfly: Tech Winners and Losers

NEW YORK ( TheStreet) -- Rambus ( RMBS) shares soared 15.1% to $8.43 Friday after it reached an agreement with Broadcom ( BRCM) over the use of patents.

The five-year patent agreement covers the use of Rambus patents used by Broadcom in its integrated circuit products. In addition, both companies have settled all previous outstanding claims.


Sina ( SINA) shares were up nearly 4% to $55.70 as rumors continued for a second day that Russian venture capital firm Digital Sky Technologies has invested in the company.

Sina owns a Weibo, a site similar to Twitter, which allows users to post messages of 140 characters.

Shares have fallen from a high of $147.12 earlier in the year to current levels, and are down 19.2% year to date.


Shutterfly ( SFLY) shares were sharply lower, off 5.3% to $23.77, after the photo sharing Web site cut fourth-quarter revenue guidance.

The company said it expects fourth-quarter revenue to be between $259 million and $264 million. It previously saw revenue coming in at a range of $270.5 million to $275.5 million.

Analysts polled by Thomson Reuters expect revenue of $267.8 million.

Tech stocks were generally rising Friday, with the Nasdaq up 12 points, as durable goods surged in November, led by orders for transportation equipment.
