Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. U.S. Steel (X) upgraded to Buy from Neutral at Citi with analyst Alexander Hacking saying he sees "good value" at 10% free cash flow yield in 2018-2019 and "considerably higher" in 2020 and beyond. 2. Schlumberger (SLB) upgraded to Buy from Hold at SunTrust with analyst Ken Sill saying that the company is typically "one of the best stocks to own in down markets" to maintain exposure to oil field services based on its diversification in product and geography. 3. Baker Hughes (BHGE) upgraded to Overweight from Neutral at Piper Jaffray with analyst Bill Herbert citing relative valuation, balance sheet strength and the company's capital light business model for the upgrade. 4. Robert Half (RHI) upgraded to Overweight from Equal Weight at Barclays with analyst Manav Patnaik saying he views the company's positioning in the U.S. as strong and he favors the shares to Manpower (MAN), which he downgraded this morning to Underweight. 5. Cognex (CGNX) upgraded to Neutral from Underweight at JPMorgan with analyst Paul Coster saying he believes the current valuation is justified by growth expectations for fiscal 2018 and recommends those short take profits following the recent pullback.
