Wall Street kicked losses to the curb again as more gains led stocks to post their best two-day run in two months. Crude boosted equities after nearing $50 a barrel and ending the session at its highest settlement since October 9. Best Buy (BBY) - Get Report bounced back from a selloff suffered a day earlier following a disappointing quarterly performance, and not even a downgrade from Deutsche Bank could squash gains. Analysts cut their rating to HOLD, citing concerns over recently-announced changes to the C-suite. Western Digital (WDC) - Get Report , meanwhile, was upgraded to OVERWEIGHT at Barclays. The firm said the move was a valuation call. Express (EXPR) - Get Report tumbled after falling short of earnings and sales estimates in its first quarter, while comparable store sales dropped 3%.
