Standard & Poor's upgraded the quality ranking on the stocks noted below. S&P's quality ranking looks at a company's growth and stability of earnings and dividends over the past 10 years.

Over the long run, higher quality stocks tend to outperform lower quality ones. In the short run though, lower quality stocks can achieve higher performance. This has been the case so far in 2009.
