Well, they’re not going to hit 65 and then sell it all in one day. They’ll be more likely to transfer their assets slowly into lower risk funds. That’s one theory at least… And besides, we can’t complain that boomers don’t have enough in retirement stocks AND refer to a “massive” selloff, both at the same time.
Also, you’re assuming that these people will even *think* about risk. Just take a look at what people of retirement age did during the .bomb Nasdaq crash. They were busy buying tech stocks because “prices can only go up”, just like housing can only go up! 😉
