San Francisco: Steve Jobs built Apple Inc. into the world's most valuable technology company with easy-to-use products that transformed the computing, wireless and music industries. The company will look for overseas growth to extend that legacy and remain an investor favourite.

Apple aims to maintain its expansion in markets such as China, fuelling sales of the iPhone and iPad. The company also stands to gain from updated versions of those best-sellers and the new iCloud service, which makes it easier for its gadgets to share information — and harder for users to switch to rival devices.

For chief executive officer Tim Cook, the challenge will be developing Apple's next generation of hot sellers and facing down competition in the markets Jobs pioneered. Google Inc.'s Android has emerged as one of Apple's biggest threats after gaining momentum in phones and tablets.

Cook, who last week led the debut of the iPhone 4S, will lean on a cadre of fellow veteran executives who have long worked together under Jobs.

"He created an infrastructure that this management team can build on for a long time," said Tim Bajarin, a technology analyst at Creative Strategies Inc. "The bigger question is how fast will they innovate and take advantage of that infrastructure for things like new devices, applications and services."

Jobs had resigned as Apple Inc. chief executive officer on August 24. He was diagnosed in 2003 with a neuroendocrine tumour, a rare form of pancreatic cancer, and had a liver transplant in 2009.

Shares fluctuate

Investors have had mixed reactions since Jobs stepped down as CEO. The shares rose more than 7 per cent in the month after he resigned, and have since slipped back to little changed. The stock fell 88 cents to $377.37 (Dh1,386) in New York on the Nasdaq Stock Market on Thursday.

The shares are recommended by 49 analysts, with no sell ratings, according to Bloomberg data. On average, analysts predict the shares will rise another 32 per cent to $499.40.

"Steve Jobs has set up the company for the next few years to have some more blockbuster products," said Giri Cherukuri, an Apple investor with Oakbrook Investments who has been following the company since the late 1980s. Updated models of the iPhone and iPad, as well as potential new products like a television, will keep the company growing, he said.

Apple's stock price has risen more than 9,000 per cent since Jobs returned to the company in 1997. The stock has more than doubled in the past two years, while Microsoft Corp. has gained 5.1 per cent and Intel Corp. has risen 14 per cent. Hewlett-Packard Co. is down 48 per cent.

While analysts once predicted that Apple shares would plunge when Jobs left the company, investors have grown more comfortable with other executives since he first went on medical leave in 2004. In 2008, Piper Jaffray Cos. analyst Gene Munster estimated that Apple shares would tumble 25 per cent if Jobs departed.

Profit doubles

Munster, who now has a target price of $607 for the stock, said Jobs' "final great act" was grooming Cook as a successor.

Apple benefited from record purchases of iPads and iPhones in the quarter that ended in June, helping profit more than double to $7.31 billion. Sales climbed 82 per cent $28.6 billion.

"For now, people are comfortable, but that could change if there are signs to the contrary," said Mike Abramsky, an analyst at RBC Capital Markets in Toronto.

In addition to Cook, Apple's executive team includes Jonathan Ive, senior vice-president of industrial design; Scott Forstall, who is in charge of the iOS software that powers the iPhone and iPad; and Philip Schiller, who leads product marketing.

Additionally, Bob Mansfield heads Mac hardware engineering; Eddy Cue runs iTunes, the App Store and iCloud; Bruce Sewell is chief counsel, putting him at the helm of the company's patent disputes; and Chief Financial Officer Peter Oppenheimer is tasked with overseeing Apple's more than $75 billion in cash and long-term holdings.

While Apple has turned its website into a memorial to Jobs, the company will quickly have to shift its focus back to the looming release of the iPhone 4S. The device, unveiled on Tuesday, goes on sale October 14.
