As per usual, the postbell spotlight was on tech stocks, as companies issued yet more stacks of earnings reports.

One of the most heavily traded names was

Apple

(AAPL) - Get Report

, which climbed 7.9% on

impressive fiscal third-quarter results

. Earnings totaled $818 million, or 92 cents a share, vs. year-ago earnings of 54 cents a share. That beats Thomson Financial's estimates by 20 cents. Shares of the Cupertino, Calif. computer giant traded choppily after the close, but were recently up $10.84 to $148.10.

Baidu.com

(BIDU) - Get Report

, a Chinese Internet-search company, soared 19% to $217.50 after

earnings rocketed

to 54 cents a share, from 33 cents a share a year ago. Wall Street had pegged earnings at 43 cents a share.

Software company

Symantec

(SYMC) - Get Report

bounced 9.4% to $21.83, after

careening past

second-quarter targets, and wireless-equipment maker

Qualcomm

(QCOM) - Get Report

gained 2.3% at $43.41 on

positive results

for that quarter. This includes a 3-cent EPS beat with surging pro-forma income of 55 cents a share.

Elsewhere, business-software firm

Omniture

( OMTR) and

Affymetrix

(AFFX)

, which makes genetic-analysis systems for the health care sector, each swung to higher-than-expected second-quarter profits. Omniture shares lifted by 6.3% to $22.53 as Affymetrix added $1.14, or 4.6%, to $26.

Akamai Technologies

(AKAM) - Get Report

was on the downswing, however, even though the Cambridge, Mass. internet-software company posted

better-than-anticipated revenue

of $152.7 million, and "normalized" in-line earnings of 30 cents a share, for the second quarter. Shares sank 12% to $41.69.

Communications-equipment maker

Arris Group

(ARRS) - Get Report

of Suwanee, Ga., predicted a below-par third-quarter profit of 19 cents to 22 cents a share. The consensus calls for 23 cents. Even though the company also achieved a penny EPS beat in the second quarter, shares were sliding 84 cents, or 4.9%, to $16.25.
