Apple stock is climbing Thursday, up 2 percent and nearing its new threshold for a $1 trillion market cap.

Shares hit an all-time high of $206.58 during early trading, just 50 cents per share short of becoming the first publicly traded U.S. company to hit the record valuation.

The company revealed an adjusted outstanding share count of 4,829,926,000 Wednesday alongside the company's third-quarter results. That factors in hefty stock buybacks and nudged the trillion-dollar per share price to $207.05.
