Tech Winners & Losers: Verizon, Riverbed

NEW YORK ( TheStreet) - Despite a strong quarter, shares of Verizon ( VZ) fell slightly Friday, while Riverbed Technology ( RVBD) saw its stock soar after earnings.

Verizon's results topped both Wall Street's sales and EPS expectations, but slow wireless subscriber growth compared to rival AT&T ( ATT) pushed the stock down. Verizon shares declined 1.3% to close at $32.09.

Shares of Riverbed Technology climbed over 18% to close at $54.27, after the company announced its third-quarter results after Thursday's closing bell. Revenues skyrocketed 45% over the same period last year to $147.8 million.

The WAN optimization company, which also announced plans for a two-for-one stock split, posted net income of $26.6 million, or 34 cents per share, compared to $14.5 million, or 19 cents per share, in the third quarter of 2009.

Riverbed's earnings performance prompted analysts from Canaccord Genuity, Wedbush and Jefferies to upgrade the stock.

Vicor Corporation ( VICR) also saw a huge trading day Friday, as strong third quarter earnings boosted the stock.

Vicor, which makes power components and systems, increased its revenue to $68.6 million from $47.7 million during the same period last year, and saw profit rise to 38 cents a share from 4 cents a share.

Shares jumped over 16.4% to close at $18.72.

Cirrus Logic ( CRUS) fell almost 4% Friday after a disappointing second quarter. Revenue increased 81% to $100.6 million, and adjusted profit rose to 40 cents a share from 11 cents a share during the same period last year.

However, the results fell short of analysts who expected a profit of 42 cents a share on $101.8 million in revenue.

The stock closed Friday at $13.22.
