Short sellers even love Apple (AAPL)

When the short interest in companies that are as robust as Apple (NASDAQ: AAPL) increases, it is a sign that investors are willing to bet against almost any firm in this market. For the period ending October 31, shares hold short in the big consumer electronics firm were up 16% to 28.1 million shares. The figure compares with short holdings as of the middle of October.

There is little obvious reason to think Apple will go lower. Its shares are below $94 already, down from almost $203 a year ago. By almost any measure, Apple is one of the most successful companies in the world, with a clean balance sheet, $33 billion in cash, growing sales, and the best products in its market segments.

The theory behind shorting Apple is that its holiday quarter will be weak. But that may be a fool's gamble. Most evidence points to Mac sales continuing to grow sharply even with most PC sales falling. The iPhone is taking market share from all other smartphones. The overall handset category may be down for the rest of the year, but Apple's product is almost certain to pick up sales.

By moving into Apple, a lot of short sellers will get burned.
