Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Mosaic (MOS) upgraded to Neutral from Underweight at Atlantic Equities. 2. CDW (CDW) upgraded to Outperform from Neutral at Baird with analyst Jayson Noland saying he believes the company is well positioned to take market share given its breadth, scale, culture, and ability to execute. Noland raised his price target to $71 from $63 on CDW shares. 3. LyondellBasell (LYB) upgraded to Buy from Hold at Vertical Research with analyst Kevin McCarthy citing recent share weakness. He believes risk/reward is turning more favorable given the likelihood of a more balanced and opportunistic approach to M&A, a "spring loaded" operational profile with various maintenance and expansion projects now complete, and attractive valuation with the highest dividend yield among US chemical stocks at 4.2%. 4. DXC Technology (DXC) upgraded to Conviction Buy from Buy at Goldman Sachs with analyst James Schneider saying DXC has sustained earnings momentum driven by margin expansion and cost synergies and raised estimates to reflect upside to synergy targets and share repurchases. 5.
