Shares of Apple (AAPL 0.53%) have been on somewhat of a tear lately, which is something that been hard to say about the Cupertino giant over the last 12 months. Many observers agree the company's stock price finally found a floor in the wake of Apple's increasing its capital return plan during its last quarterly earnings report. And while the shares aren't as cheap as several weeks ago, investors would be mistaken to think there isn't plenty of upside from today's levels. In fact, shrewd investors should be keenly aware of the signals management is sending to them loud and clear.
