money managers are buying into the rally because they have to. What is their exit plan?

I heard money managers are chasing performance and buying stocks at high prices, window dressing, magnificent 7, like monkeys with a broken sell button.

Maybe they bought AAPL at $190 and NVDA at $500, adding fuel to the rally.

They must know they are paying too much.

those of you who are familiar with how money managers behave, what do you think is their exit plan after buying this high?

Would you bet they're gonna dump it all in the new year?
