Why exclude the most recent month in momentum?

The most recent month shows short-term reversal (microstructure noise). Momentum is typically calculated using 12 months return minus the most recent month (12-1 momentum) to avoid this reversal.

What is the momentum crash risk?

Momentum strategies can crash violently in sharp reversals (2009, 2020 recovery). After severe selloffs, prior losers bounce dramatically, causing momentum portfolios to lose 30-40%+ in short periods.
