From what I've read, small cap funds have dropped more than large caps during these downturns the last few years and generally have risen more during the rebound months. So when buying in after a downturn, wouldn't it be better to prioritize small cap funds over large cap? Diversify to mitigate risk of course, but I would think that putting more into small cap than normal during a downturn makes sense. It can't be that easy though, otherwise everyone would do it, so are there other factors that make this a bad move?
