CM Earnings Day: Another Surprise in Line with History?

Canadian Imperial Bank Of Commerce (CM) announced its earnings today, and the stock responded with a 1.9% bump, pushing its latest price to $76.61. But for anyone following the options market, this move might feel muted—traders had priced in an expected move of ±4.5%. Was the reaction underwhelming, or does it hint at a bigger story just beneath the surface?

What Happens After Earnings? Trend Shifts and Post-Event Drifts

For traders and investors wondering whether to stick around after the earnings pop, history offers mixed clues.
