Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. McDonald's (MCD) upgraded to Outperform from Market Perform at Wells Fargo analyst Jeff Farmer saying margin and return on invested capital improvement with refranchising activity should drive accelerating multiple expansion into 2018. Further, McDonald's first mover advantage across digital, specifically mobile order and pay, should bring the return of market share gains, the analyst contends. Farmer believes restaurant consumers are "aggressively gravitating toward concepts that offer the greatest level of convenience and control across ordering, payment and distribution." He expects McDonald's to establish a first-mover advantage among the hamburger players in digital. 2. Cummins upgraded to Outperform from Market Perform at Wells Fargo with the firm saying the company's first quarter results could beat expectations and that it could raise its guidance slightly above consensus levels. The firm says that the company's cost reductions and improvements in its end markets should enable its profit to beat expectations. Wells expects the company's 2017 revenue and EBIT margin to exceed the top ends of its current guidance ranges. 3. PNC Financial (PNC) upgraded to Neutral from Underperform at Hilliard Lyons with analyst Andrew Stapp citing valuation. 4. Constellation Brands (STZ) upgraded to Conviction Buy from Buy at Goldman Sachs with analyst Judy Hong citing valuation and best-in-class growth. The analyst believes concerns about the recent slowdown in beer sales is overdone and said the company's lower production costs, favorable below-the-line items and share buybacks point to earnings upside potential. 5. Quotient Technology (QUOT) upgraded to Buy from Neutral at BofA/Merrill with the firm noting that no retailer has left the company's Retailer IQ platform after three years and new partners increase the firm's confidence that the platform can keep growing. The firm also sees the company's mobile first approach allowing Quotient to build on its position as the digital coupon distribution leader.
