SEI Investments

(SEIC) - Get Report

upgraded at Oppenheimer. Rating raised to Outperform from Perform. Establishes $22 price target. 2009 EPS estimates raised to $0.93 from $0.86.

Safeway

(SWY)

upgraded to Buy at Jefferies from Hold and price target increased to $26 from $20. Stabilization of the macro climate could really add some sizzle to the Safeway story. SWY's home turf has been battered with cities like Portland and San Jose seeing unemployment spike by over 500 bps in the last year, much more than the national average of 390 bps. Jefferies believes that Safeway should see an outsized benefit if the economy improves. The valuation is compelling at 9x below-consensus FY10 estimate and a free-cash-flow-yield of 11%. DCF places the intrinsic value at roughly $36, using a relatively conservative long-term EBIT estimate of 4.0%.

Valeant Pharmaceuticals

(VRX)

downgraded at Wachovia. Rating lowered to Underperform from Market Perform. Valuation range lowered to $15-$17 from $15-$18. 2009 EPS estimates lowered to $1.16 from $1.26.

US Steel

(X) - Get Report

upgraded at Morgan Stanley from Equal-weight to Overweight. $45 price target. Fundamentals are improving and a pick-up in US demand could soon follow. Following a recent sector rally, thr company appears to have the most upside potential.
