FYI: The month of May brought near-record asset outflows from equity ETFs totaling about $16 billion. This massive exodus—the biggest single-month outflow since at least early 2014—suggests investors are panicked, trimming their exposure to risk assets at an impressive rate (read: Largest Monthly ETF Outflow Of 2019 In May).
Asset flows are, after all, a good indicator of investor sentiment, even if a laggard one.
