After a 53% gain over the last year, shares of Walgreen Company (NYSE: WAG ) are seeing a pullback after earnings. The stock, currently trading lower by almost 8%, follows Rite Aid Corporation (NYSE: RAD )'s 11.5% loss during the last five sessions. However, make no mistake about it, this is a pullback, not the start of a large trend lower, and these stocks are still a buy. Lousy Stock Performance Does Not Indicate Bad Quarters I always tell people, read the quarterly report first, listen to the conference call second, and by that time the stock will have found a steady trading range. In the meantime, make an assessment of the quarter based on the information in the conference call and in the quarterly report, not based on the stock's performance. With that said, here is how I assess the quarterly reports of both Walgreen and Rite Aid Corporation (NYSE:RAD). Walgreens missed quarterly expectations and saw a horrible decline in store traffic of 3.9% year-over-year.
