CHANGE IN RATINGS

Best Buy ( BBY) upgraded at Oppenheimer to Outperform from Perform based on attractive valuation as shares are down nearly 20% since early June. Price target was lifted to $42 from $40. Estimates also raised to reflect better sales at BBY in Jan./Feb.

Bank of New York Mellon ( BK) downgraded at Goldman from Conviction Buy to Buy because it will be less of a catalyst compared to the other firms in its sector. Target price set at $39.

Compass Minerals ( CMP) downgraded to perform from outperform and $61 price target withdrawn. Potash pricing appears to be ready to crumble, which would directly impact CMP.

Capella Education Company ( CPLA) downgraded at Credit Suisse to Neutral from Outperform. Cites full valuation from a recent rally and concerns about the sector's legal/regulatory environment. Maintained target price of $61.

Discover Financial ( DFS) upgraded at Goldman to Conviction Buy as consumer delinquencies are improving, capital raise behind its stock, it is trading below tangible book, and the co. should be profitable in 2H09 given reserve builds and loan repricing. Target price set at $12.

Goldman Sachs ( GS) upgraded at Meredith Whitney to Buy. $186 price target. Expect more debt issuance to fund budget gaps, and the company should gain market share in this area.

WW Grainger ( GWW) upgraded at Merrill/BofA from Neutral to Buy. $100 price target. Estimates also raised, to reflect cost-savings.

Intrepid Potash ( IPI) downgraded at Oppenheimer to Underperform from Outperform as potash pricing appears ready to drop sharply. Oppenheimer withdrew their price target.
