Morgan in the fifth paragraph and updated shares price.NEW YORK ( TheStreet) - Apple ( AAPL) shares hit $500 for the first time on Monday, as the iPhone maker pushes towards a $500 billion market cap, but should traders and investors take pause after Apple's recent run-up? It depends on your time-frame, according to a variety of traders and analysts. Every stock has ebbs and flows, and Apple is no different, having soared 23.4% year-to-date. This far outpaces the broader NASDAQ, which has returned 12%. Competitors such as Research In Motion ( RIMM) and Google ( GOOG) have returned 4.9%, and -5.4%, respectively.
