SAN FRANCISCO (Reuters) – Leading cellphone chipmaker Qualcomm raised its full-year revenue forecast as demand for smartphones continues to grow, but its estimate for full-year earnings was shy of expectations and its shares fell sharply.

San Diego-based Qualcomm is benefiting from strong demand for smartphones and a shift by network operators worldwide to a high-speed wireless technology known as long-term evolution (LTE), where the chipmaker is ahead of rivals.

SAN FRANCISCO (Reuters) – Broadcom’s first-quarter results beat expectations and the chipmaker said much of its growth this year would come from selling more components to smartphone makers.

Broadcom’s quarterly earnings report pushed the chipmaker’s shares up after hours as company executives said they expect their baseband chips to appear in upcoming handsets.

SAN FRANCISCO (Reuters) – Chipmaker Broadcom (BRCM.O: Quote, Profile, Research, Stock Buzz) posted first-quarter profit and revenue above expectations and its revenue forecast also topped estimates, despite investors’ worries about slower growth at key customer Apple (AAPL.O: Quote, Profile, Research, Stock Buzz).

Broadcom, whose chips are used in products ranging from television set-top boxes to Apple’s iPhone, posted first-quarter revenue of $2.01 billion, up 9.7 percent from the year-earlier period.

April 22 (Reuters) – Texas Instruments Inc posted
first-quarter results slightly ahead of Wall Street expectations
and it forecast growth for the current quarter on improving
demand for its chips.

global economy, orders for Texas Instruments’ chips have picked
up, although manufacturing customers remain cautious, Chief
Financial Officer Kevin March told Reuters in a telephone
interview.

(Reuters) – Advanced Micro Devices Inc forecast current-quarter revenue above Wall Street’s expectations as it rushes to find new markets to offset its declining core business of PC chips.

SAN FRANCISCO, April 18 (Reuters) – Apple Inc’s
shares fell below $400 on Wednesday for the first time since
December 2011 after a U.S. chip supplier’s disappointing revenue
forecast fanned fears about weakening demand for the iPhone and
iPad as competition intensifies.

The surprise warning by Cirrus Logic Inc knocked
down shares of key component suppliers like South Korea’s LG
Display Co Ltd and Japan’s Toshiba Corp on
Thursday in Asia, a region that supplies the lion’s share of
chips, cases and displays for the Cupertino, California-based
company.

SAN FRANCISCO (Reuters) – Apple Inc’s (AAPL.O: Quote, Profile, Research) shares fell below $400 on Wednesday for the first time since December 2011 after a chip supplier’s disappointing revenue forecast fanned fears about weakening demand for the iPhone and iPad as competition intensifies.

The stock dropped below $400 briefly before bouncing back to end 5.5 percent lower at $402.80, losing more than $22 billion of market value in a single day.

SAN FRANCISCO, April 17 (Reuters) – U.S. memory chipmaker
SanDisk on Wednesday posted quarterly results above

SAN FRANCISCO (Reuters) – Apple Inc’s shares fell on Wednesday below $400 for the first time since December 2011, after key supplier Cirrus Logic’s disappointing revenue forecast fanned fears that weakening demand for the iPhone and iPad are pressuring margins more than anticipated.

Apple, which fell through $400 briefly before bouncing back to stand 5.5 percent lower at about $403, has lost more than 40 percent of its market value since a September 2012 peak, battered by worries about intensifying competition and its effect on the company’s industry-leading margins.

SAN FRANCISCO (Reuters) – Intel Corp said its current-quarter revenue would decline as much as 8 percent and trimmed its 2013 capital spending plans, as personal computer sales drop due to the growing popularity of tablets and smartphones.

Shares in the world’s largest chip maker rallied as much as 3 percent after hours but quickly gave up the gains. The stock had been battered over the past week after researcher IDC revealed that PC sales notched a record quarterly decline in the first quarter.
