Wall Street is giving Apple’s post-Steve Jobs transition a thumbs-up, at least so far. The company’s shares rose 2.78% today to close regular trading at $411.63, an all-time high for Apple. The surge gives it a market valuation of $381.6B, making it the most valuable company on the stock market. Exxon Mobil had held the top market cap at $358.3B. The stock is up 10.14% since the day after Jobs stepped down as CEO and was replaced by Tim Cook nearly a month ago.
