Regions Financial (RF) upgraded to Buy from Neutral at BofA/Merrill with analyst Erika Najarian saying the market is undervaluing a "significant capital return story" following the year-to-date underperformance relative to peers.

Wells Fargo notes that a group of seven domestic solar product makers, including First Solar (FSLR), filed a petition to levy anti-dumping and countervailing duties on solar imports from Cambodia, Malaysia, Thailand and Vietnam, looking for duties ranging from 70.4% to 271.5%. The firm, which included the "important reminder" that "this is just a petition," says the uncertainty created by the petition is "incrementally positive" for First Solar and negative for Canadian Solar (CSIQ), Array Technologies (ARRY) and Nextracker (NXT).

Bunge is down -6.6%, or -$7.20 to $102.42.
