Nokia Corp. (NOK, $9.15, +$0.33, +3.74%), the world's largest mobile phone maker, said profit for the second quarter fell as it struggled to compete with rivals like Apple Inc. (AAPL, $259.43, +$5.19, +2.04%) in the premium smartphone segment, but it expects new devices to spur a rebound later this year. Orbital Sciences Corp.'s (ORB, $14.93, -$0.69, -4.42%) profit dropped an unexpected 27% despite a 25% increase in revenue as the rocket maker said it saw higher costs because of the Galaxy 15 Satellite, which drifted out of its orbit, and because of the cancellation of its Orion spacecraft contract. Penn National Gaming Inc.'s (PENN, $26.69, +$2.59, +10.75%) second-quarter earnings fell 68% as the casino and racetrack operator posted $30.6 million in write-downs and demand remained soft. Still, results beat analysts' expectations. Other casinos trading higher Thursday included Boyd Gaming Corp. (BYD, $8.06, +$0.45, +5.91%), MGM Resorts International (MGM, $10.13, +$0.44, +4.54%) and Wynn Resorts Ltd. (WYNN, $84.93, +$2.97, +3.62%).

Qualcomm Inc.'s (QCOM, $39.30, +$3.14, +8.68%) fiscal third-quarter profit rose 4.1% as shipments of its mobile station modem chips increased 10% to a record 103 million units. The world's largest wireless-chip maker's results topped its forecast and it increased its year earnings forecast again. Citi cut its rating on Quest Diagnostics Inc. (DGX, $45.03, -$1.67, -3.58%) to hold from buy after the clinical laboratory owner posted second-quarter revenue that dropped more than expected, and lowered its 2010 earnings outlook on a further slowdown in physician-office visits. "We find ourselves publishing such significant downward revisions that our growth estimates no longer support a materially higher valuation," Citi noted. Royal Caribbean Cruises Ltd. (RCL, $27.22, +$2.64, +10.74%) recovered from a prior-year loss in the second quarter caused by charges and lower revenue as the cruise operator continued to see more signs of a travel and tourism recovery and topped expectations. The result exceeded estimates and also boosted shares of competitor Carnival Corp. (CCL, $33.68, +$2.25, +7.16%). Safeway Inc. (SWY, $19.79, -$0.43, -2.13%) cut its guidance for the year as deflation continues to hurt profits and sales at the supermarket chain, whose second-quarter profit fell 41%. Sherwin-Williams Co.'s (SHW, $67.35, -$2.21, -3.18%) second-quarter earnings rose 15% as the paint company reported continued sales improvement over last year's slumping levels. While results beat analysts' expectations, the company trimmed back its 2010 profit target from April's boosted level. SolarWinds Inc. (SWI, $13.00, -$3.52, -21.31%) shares plunged Thursday after the network-management software company lowered its expectations for the year, pointing to unfavorable exchange rates, a longer sales cycle and slower growth in Europe. The company also issued a disappointing view for the current quarter. Starwood Hotels & Resorts Worldwide Inc.'s (HOT, $45.42, +$1.62, +3.70%) second-quarter earnings fell 15% on charges as the lodging company continued to see demand improve. Results beat analysts' expectations and Starwood boosted its 2010 forecast again. Other hotels also were trading higher following Starwood's results and a strong showing from LaSalle Hotel Properties (LHO, $23.00, +$1.34, +6.19%). STR Global, an independent research company that tracks the lodging industry, Thursday reported "marked improvement" in first-half and second-quarter U.S. hotel industry performance. Gainers included Marriott International Inc. (MAR, $31.95, +$1.19, +3.87%), Host Hotels & Resorts Inc. (HST, $13.92, +$0.34, +2.50%), Wyndham Worldwide Corp. (WYN, $21.97, +$0.95, +4.52%) and Orient Express Hotels Ltd. (OEH, $8.14, +$0.34, +4.36%). St. Jude Medical Inc.'s (STJ, $35.51, +$0.89, +2.57%) second-quarter profit grew 16% on higher sales across the board. Results topped expectations and the medical-device maker which specializes in cardiovascular products such as heart valves and pacemakers raised its 2010 earnings target. TrueBlue Inc. (TBI, $12.20, +$1.12, +10.11%) more than doubled up the Wall Street consensus estimate for its earnings per share as the staffing company, which specializes in blue-collar work, said it continues to see customers rely on temporary labor so they can remain flexible. Union Pacific Corp.'s (UNP, $73.50, +$4.38, +6.33%) second-quarter profit climbed 53% as the railroad company posted volume growth for the second consecutive quarter and notched freight revenue growth across all business segments. The company's bottom line topped expectations. VF Corp.'s (VFC, $78.30, +$4.34, +5.87%) second-quarter profit jumped 47% as revenue grew across the board. As it posted record earnings in the quarter, the world's biggest clothing maker by revenue raised 2010 guidance. Western Digital Corp.'s (WDC, $28.32, -$1.86, -6.16%) fiscal fourth-quarter profit climbed 35% on double-digit growth in sales and shipments despite demand being softer than expected. The disk-drive maker's results fell short of Wall Street's expectations. -By Dow Jones Newswires; write to [email protected] (END) Dow Jones Newswires July 22, 2010 13:38 ET (17:38 GMT)
