Hillary Clinton has been Wall Street’s presidential darling so far by a large margin, but could be about to face some competition.

“Earlier this year, Wall Street was outright hostile to Trump,” said Greg Valliere, chief global strategist at Horizon Investments and an expert on the Wall Street-Washington nexus. “Now, Wall Street is beginning to warm up to him, especially since it looks like he might have a chance.”

“Will Trump begin to moderate his views toward Wall Street? Maybe, because people on Wall Street have talked to him, or maybe because he needs money from them,” Valliere said. “All of a sudden he’s gone from being a big Wall Street critic to favoring Wall Street very much.”
