When Apple passed the giants–General Electric , Johnson & Johnson , Procter & Gamble , and even Google –in terms of stock-market value this week, we started wondering: What company in the universe has the highest stock-market capitalization per employee?

We ran the number and it turns out to be…Google!

Even as Apple has surged on the heels of Monday’s blowout quarterly earnings report–and news of upcoming products like its Tablet computer/e-reader–Apple’s $187.7 billion stock-market value translates to $5.8 million per employee.

That’s certainly impressive. It surpasses the market cap/employee of Exxon Mobil , Microsoft and Wal-Mart , which happen to be the only three U.S. companies whose total stock-market capitalization is higher than Apple’s today.

But Google is the champ in terms of human capital: Its current $175.5 billion market value translates to $8.6 million per employee.

How thrilling–or maybe frightening–to know that this level of investor confidence is riding on Googlers worldwide.
