Netflix (NASDAQ: NFLX), a DVD-rental business that competes with Blockbuster (NYSE: BBI), was upgraded yesterday by Michael Pachter, an analyst with Wedbush Morgan Securities. He sees good tidings ahead for the company. He believes that Netflix will see higher margins and a healthy stream of earnings. His thesis centers on the fact that the subscriber base is likely to grow and that streaming movies will lower the cost of delivery.
Upgrades are tricky beasts. Ideally, an investor or, more likely, a trader, wants to be in the stock before the upgrade occurs. Buying a company after it's been upgraded requires a lot of due diligence. And you have to get over the fact that you might be buying at a high price.
