TheStreet Ratings team rates APPLE INC as a Buy with a ratings score of A+. TheStreet Ratings Team has this to say about their recommendation:
"We rate APPLE INC (AAPL) a BUY. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that we rate. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures, notable return on equity, expanding profit margins and solid stock price performance. Although the company may harbor some minor weaknesses, we feel they are unlikely to have a significant impact on results."
