On July 20, 2011 Apple filed with the Securities and Exchange Commission (SEC) its Form 10-Q for the quarterly period ended June 25, 2011.

According to the document, which looks at Apple Inc.’s figures in detail, Steve Jobs received zero reimbursements for his corporate jet for the second quarter in a row.

Coincidentally, AAPL is trading a record high of $387.29.

CNN Money’s Fortune has been keeping a close eye on AAPL ever since Morgan Stanley analyst Katy Huberty encouraged investors to buy Apple stock based on how much time the CEO was airborne.

Her theory was that big jet fuel reimbursements were a direct result of Jobs being "integral to negotiations with international carriers and supply chain partners."

However, that assumption turned out to be false.

In fact, this is not the first time Apple’s stock reaches for the sky at the same time as Jobs’ jet stays grounded, gathering dust.

According to Fortune, Apple's shares did even better the last time Steve Jobs attended to his health problems.

As Jobs was recovering from a liver transplant, the stock rose nearly 114%, from January to September 2009, the paper notes.

Where the Fortune report ends, we begin to speculate that Jobs staying grounded is still a reason for concern.

AAPL may be performing well for investors now, but Jobs’ health is a key factor in maintaining the profitability of Apple stock.

As he is still to confirm his return as CEO full time, Jobs not using his private jet may just as well be a reason for concern.

Even if the Apple boss has fellow execs that are well trained to carry out some of his tasks, investors and Apple partners alike still identify Apple with the iconic Steve Jobs.
