Apple's Improbable Math

Apple's (NASDAQ:AAPL) original corporate logo depicted Isaac Newton reading under the shade of a tree, an apple dangling from a branch overhead. The story goes that the young Newton was inspired to his theory of gravity when the apple dropped on his head. Four centuries later, investors in Apple Inc. are about to re-discover that gravity can still leave a bruise.

It was in late August that Apple became the most valuable U.S. company ever, surpassing the $620 billion market cap that Microsoft (NASDAQ:MSFT) reached in 1999 during the tech stock mania. Far from becoming nervous about the record price, Apple enthusiasts were cheered by sales of the iPhone 5, prospects for the iPad mini, the potential of a breakthrough TV service, and the seemingly unlimited growth potential in emerging markets. Doubts about the stock were mollified by a seemingly low price-earnings ratio and near-unanimous "Buy" ratings by Street analysts. There was even some comfort - oddly - in the observation by S&P Capital IQ that Apple would need to reach $900 per share before it would exceed the "inflation-adjusted" price of the old, bubble-induced Microsoft record.

Shares have pulled back from recent highs, but bullish investors see this as another opportunity to buy. Can the stock really provide a decent return at today's price? After seeing shares leap 38% year-to-date, it's hard to imagine new Apple shareholders being satisfied with a pedestrian gain of 10% in the coming year, but achieving even this would require a Herculean effort.

To gain that 10%, Apple would need to add $52 billion in market value. In the jumble of trillion dollar deficits and hundred billion dollar bailouts, we've become so used to big numbers that we've lost sight of just how big they are. That additional $52 billion is more than the current market cap of more than 85% of the companies in the S&P 500. So, Apple would need to add value in the coming year greater than the current market cap of such giants as Honeywell (NYSE:HON), Colgate Palmolive (NYSE:CL), Ford Motor (NYSE:F) and Costco (NASDAQ:COST). Don't even think about how hard it will be to do this the year after that.

The vaunted Apple ecosystem of devices, content and apps provides real business advantages, but the extraordinary profit the company enjoys invites intense competition that will make it harder and harder to stay ahead. Improvements to the iPhone and iPad are already becoming more evolutionary than revolutionary. And the expansion of open platforms like HTML5 promise to give consumers access to content and apps without the need to buy the high-priced devices sold by Apple. This may prove especially appealing as a chronically weak economy prompts buyers to look for ways to save money.

Doubtless the spectacular popularity of Apple products has led to a halo effect for the stock. Despite the popularity of books that highlight the dangers of letting emotion override rationality when making decisions, investors are still most comfortable going along with the crowd. That goes double for professional investment managers, who feel pressure to own a stock like Apple that bulks large in the S&P 500 and has posted big price gains. As Newton said in another moment of insight, "I can calculate the motion of heavenly bodies but not the madness of people."
