AAPL Stock Closes at $100.53, Just Short of All-Time High

It's a good time to have Apple stock. After a couple of years of occasionally precipitous declines, the Cupertino giant's stock is at last back to the dizzying levels we last saw back in 2012. Even better, the stock closed today at $100.53, which almost marks an all-time high for the iPhone maker (adjusted after the recent stock split).

The rumors surrounding Apple's fall lineup have much to do with the long climb to the top, and RBC and Morgan Stanley spread the flames further after releasing reports today that touted its rumored upcoming products.

Looks like billionaire investor Carl Icahn was right, after all. Last year he claimed Apple's stock was vastly undervalued, and he snatched up around $4.4 billion in shares while the stock was at some of its lowest levels. Today he took to Twitter calling AAPL stock a "no brainer," and claiming that "anyone who invested at that time would be up 53 percent (including dividends)."

The last time the stock was this high, Apple was on the eve on releasing the iPhone 5 on September 19, 2012 and shares had reached a split-adjusted record of $100.72. The stock plummeted not long after in the wake of fears that the Cupertino company had run out of good ideas after Steve Jobs' passing.

Now, however, Apple once again seems unstoppable. Its continued success depends on the strength of its upcoming product lineup, however, which is rumored to include two new iPhones with larger displays and the long-rumored "iWatch" (which may not appear until 2015).
