Monday's Tech Winners and Losers

Updated from 1:45 p.m. EST with new stock prices

Tech stocks were down Monday on broader market concerns about the strength of the financial services industry, following a Goldman Sachs(GS Quote) analyst's sell recommendation for Citigroup(C Quote) and continued worries about consumer spending.

EchoStar Communications(DISH Quote) rose more than 19% on news that it is in the final stages of negotiating a $29.5 billion buyout deal with telecom giant AT&T(T Quote).

EchoStar's Dish Network could help AT&T expand outside its largely Southwestern markets and give it the video expertise and programming agreements to operate on a national level, say analysts. The final price for the satellite-TV operator, still under negotiation, is likely to be range from $64 to $68 a share, according to a story in TheStreet.com. EchoStar was up $7.66, or 19.2%, to $47.49. Meanwhile AT&T was down $1.80, or 4.6%, to $37.75.

Vasco Data Security(VDSI Quote) jumped 4.1% after a Friedman, Billings, Ramsey group analyst upgraded the stock from market perform to outperform. Analyst Daniel Ives said the recent sell-off in Vasco's stock is overdone and represents a buying opportunity.

Vasco's business remains strong in Europe, where the company gets most of its revenue. Also, the recent turmoil in the company's financial services segment, where there is a significant customer base, should not affect it extensively, Ives said in a research report. Vasco shares have fallen 40.5% in one month. The stock was up 87 cents to $22.14.
