Stocks pulled in both directions after the market close Tuesday, and among the gainers was

Applied Materials

(AMAT) - Get Applied Materials, Inc. Report

.

Shares added 4.9% after the Santa Clara, Calif., chipmaking-equipment maker

topped estimates with fiscal first-quarter earnings of 23 cents a share, excluding certain restructuring charges. That's lower than year-ago non-GAAP income of 28 cents a share, but Wall Street was looking for just 20 cents a share, according to Thomson Financial. Revenue also slipped 8.3% year over year to a better-than-expected $2.09 billion. Applied Materials stock was up 89 cents to $18.96, more than taking back all of its regular-session losses.

A particularly big postclose winner was

Buffalo Wild Wings

(BWLD)

, shares of which shot up 12.8% to $26.40 after fourth-quarter income didn't drop nearly as much as analysts had expected. The Minneapolis-based restaurant-chain operator said per-share earnings fell by 4 cents year over year to 34 cents against the 31-cent consensus. The company also reported that same-store sales rose 3.4% at company owned locations and 2.3% at franchises, while total revenue jumped 18.9% year over year -- excluding last year's extra operating week -- to an in-line $91.4 million.

Cephalon

( CEPH) beat handily, as well. The Frazer, Pa., drugmaker swung to a fourth-quarter GAAP-based profit on climbing sales of $450 million, and adjusted earnings came to 83 cents a share. The Street had sought 77-cent EPS on $437.6 million in sales. Shares were tacking on $2.02, or 3.5%, to $60.49 in choppy, light after-hours trading.

And California-based biotech company

Genentech

( DNA) rose 2.3% to $71.50 after it and partner

Roche

announced achieving the primary endpoint in a late-phase trial. The companies said that that Avastin, in combination with chemotherapy, successfully prolonged progression-free survival in patients with metastatic breast cancer who hadn't been previously treated with chemotherapy.

Among the biggest decliners, however, was

Blue Nile

(NILE)

, which dove 21.2% after the online jewelry retailer projected first-quarter income at between 11 cents and 14 cents a share, the midpoint of which is 10.5 cents under analyst targets. Blue Nile beat by a penny for the fourth quarter, but shares were nonetheless plunging $11.42 to $42.43 after hours.

Similarly, chipmaker

Anadigics

(ANAD)

came in a penny ahead for the fourth quarter but estimated current-quarter earnings at a below-par range of 9 cents to 11 cents a share. Analysts are calling for 13 cents a share. Shares lost 5.4% to $9.80 in recent late trading.

Elsewhere, casino-resort operator

Wynn Resorts

(WYNN) - Get Wynn Resorts, Limited (WYNN) Report

was losing ground even though it swung to a GAAP-based profit for the fourth quarter and said adjusted income spiked 44.6% year over year to $82.6 million, or 72 cents a share. That's 4 cents ahead of the average analyst estimate.

Wynn also reported slightly weaker results at its Las Vegas resort. Property earnings before interest, taxes, depreciation and amortization slipped 3.8% vs. a year earlier at $97.3 million, and casino revenues were down by a hair to $160 million, though gross non-casino sales climbed 8.1%. At its Macau resort, meanwhile, adjusted property EBITDA soared more than 70% to $99.6 million and casino sales were up 19.9% to $642.3 million, said the company. Wynn shares were changing hands at $114.06.
