Stock Market's Momentum Trade Faces a Risky July Unwind
Momentum trades historically struggle in July, and one strategist warns this year's unwind could be especially volatile.
Every summer, Wall Street's momentum trade — the strategy of buying what has already been rising and selling what has been falling — faces a well-documented seasonal headwind.
