An investment perspective Rite Aid might be the hottest investment of the three right now, but if you're looking to invest in the strongest underlying business with the best odds of long-term success, then it's likely to be Walgreen or CVS, with Walgreen holding a slight edge thanks to its Amerisource Bergen deal. Walgreen also offers a dividend yield of 1.90%, whereas CVS yields 1.50%. Rite Aid doesn't pay a dividend. Please do your own research prior to making any investment decisions.
