Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Regeneron (REGN) downgraded to Neutral from Buy at Goldman by analyst Terence Flynn, citing valuation with the stock within 9% of his unchanged $417 price target. The analyst sees less upside potential relative to Regeneron's large-cap peers Amgen (AMGN) and Alexion (ALXN), he said. 2. GoDaddy (GDDY) downgraded to Hold from Buy at Summit Redstone by analyst Jonathan Kees, who notes that management brought down growth expectations for its three segments. Kees believes the integration of HEG may be long as personnel need to be trained on GoDaddy products, sales, and service before market expansion begins and believes shares could pullback similar to Web.com (WEB) and Endurance (EIGI) as they went through their acquisitions. 3. Wells Fargo (WFC) downgraded to Neutral at Credit Suisse by analyst Susan Roth Katzke, citing valuation. 4. Angie's List (ANGI) downgraded to Sell from Neutral at Roth Capital by analyst Darren Aftahi, who lowered his price target for the shares to $4.75 from $6.50 following the company's Q4 results. 5. Groupon (GRPN) downgraded to Neutral from Outperform at Wedbush by analyst Aaron Turner, saying shares have achieved his $4.50 price target.
