As holiday shoppers snap up iPads and raise income for Apple, investors are now stepping back as their industry oracle, Apple's Chief Executive Officer, Steve Jobs is to take further medical leave of absence.

This has triggered a slip of more than two percent in regular trading of Apple shares.

Apple did not give any information beyond Jobs' six-sentence note announcing his leave.

In the note, Jobs says he will continue as CEO and will still be involved in major decisions. Chief Operating Officer Tim Cook will be responsible for all day-to-day running of the company.

It's not known whether the 55-year-old is acutely ill, whether the leave is related to his 2009 liver transplant, or if he is at home or in a hospital.

The news has somewhat reduced investors' confidence, but analysts believe the company is in good hands with the current slate of executives, though facing increasing competition from Google and others.

Clyde monevirgen, Equity Analyst, Stranded and Poor, said, "What Steve Jobs has done is he's created very successful products but in addition to that he has also created a very successful organization that is backed by leaders and engineers and managers that are very capable. One of them being Tim Cook,"

Apple expert Leander Kahney is also confident the company will carry on, even in Jobs' absence.

Leander Kahney, Apple Expert, said, "They have a lot of stuff in the pipeline and just the momentum of the thing. It's a huge snowball rolling up hill, I mean, that's not going to stop. So they are actually going to thrive if he steps down now"

As an industry oracle, Jobs invents products he knows consumers will want even before they realize it.

As a demanding and hands-on leader, Jobs is involved in even the smallest details of product development meaning every bit of news or rumor of his health will affect the share price.
