Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. FedEx (FDX) upgraded to Outperform from Peer Perform at Wolfe Research, citing increased confidence in higher earnings growth driven by continued Express profit growth, market share gains, accretion from TNT, buybacks, and a meaningfully lower tax rate. 2. Square (SQ) upgraded to Neutral from Underperform at Wedbush based on valuation. 3. Aimco (AIV) upgraded to Buy from Neutral at UBS, with analyst Nick Yulico saying the company's fundamentals will be less exposed to new supply than peers given its exposure to Class B assets. 4. Genesis Energy (GEL) upgraded to Buy from Neutral at Citi, with analyst Faisel Khan saying the company's growth story is underappreciated and its cash flow cliff is likely exaggerated. 5. Weingarten Realty (WRI) upgraded to Buy from Neutral at UBS, with analyst Jeremy Metz citing the company's "defensively positioned" portfolio and attractive valuation relative to peers.
