Symantec

(SYMC) - Get Report

.

Shares lost ground after the Cupertino, Calif.-based security software company predicted non-GAAP earnings would be between 25 cents and 30 cents a share in the fiscal third quarter. That would miss the mean estimate by at least a penny. Second-quarter income of 29 cents a share was

better than anticipated, but shares were still off 11.12% to $18.68.

Cirrus Logic

(CRUS) - Get Report

tumbled 9% to $6.35 after the Texas-based chipmaker swung to a GAAP-based fiscal second-quarter loss of $332,000 vs. last year's $9.3 million profit.

F5 Networks

(FFIV) - Get Report

gave up 9.8% after fiscal fourth-quarter earnings slid 28.6% to 15 cents a share. Excluding a one-time, 16-cent acquisition charge, results come in well over analysts' expectations for 11 cents a share. But F5 shares were still trading down, to $36.52.

The company also announced the

departure of Senior Vice President of Worldwide Sales Tom Hull. Mark Anderson will replace him.

Align Technology

(ALGN) - Get Report

, maker of Invisalign braces, took a hard postclose fall after saying that CFO Eldon Bullington plans to retire in December. He will be succeeded by Kenneth Arola.

Weight-management company

NutriSystem

(NTRI) - Get Report

topped third-quarter profit estimates by a penny a share, but it also projected next-quarter sales to be flat with last year's $133.6 million. Analysts are looking for $143.7 million in revenue. The company also cut full-year sales guidance by at least $34 million, to between $770 million and $776 million.

The Horsham, Pa., company additionally named David Clark as its new CFO to replace James Brown, whose upcoming resignation was announced in August. NutriSystem shares surrendered $2.72, or 9.9%, to $24.78.
