Probably bad things, which is why I feel (marginally) safer in VTV, Vanguard's large cap value fund, focused on consumer staples, insurance companies, holding companies like Berkshire, defense contractors...basically large companies with the lowest P/E and P/B ratios. I'm not saying it won't hurt when the bubble collapses, but it intentionally excludes the FAANG and overpriced tech.

It ain't perfect by any stretch, but it at least tries to capture profitable and (relatively) underpriced companies with proven records instead of market darlings.

VXUS for exposure to foreign markets. BNDW for the ginormous market of bonds.

The crash will hurt. It'll be a good buying opportunity for anyone with cash. I have a few more decades to weather the storm, so I'm just staying steady. I've already tried my hand at picking stocks (gambling) and learned the hard way (because I ignored the books telling me what not to do) that I suck at gambling. Technically, any normal person is supposed to suck at gambling, otherwise it wouldn't survive as a venture.
