Three 2020 Democratic candidates are "generating most of the buzz" among Wall Street donors: Joe Biden, Sen. Kamala Harris and Pete Buttigieg, the New York Times reports.

Driving the news: Nine candidates over nine days will hold fundraisers in New York, racing to bring in cash ahead of a June 30 filing deadline.

Between the lines: "[T]hose who care most about picking a winner are gravitating toward Mr. Biden and Ms. Harris, while donors are swooning over Mr. Buttigieg enough to open their wallets and bundling networks for him," per the Times.
