It depends on how close you are to retiring. If you are more than 10 years away, you are probably better off doing nothing differently. Look at the inevitable dip as a buying opportunity.

Even if you are close, you still need to be careful. Yes, the market is probably due for a 40% haircut at some point. But if it takes another 3 years to get there, then the market might increase more than that before then.

There are funds that track the entire S&P 500, but omit those 7 large Tech companies, and their performance has consistently lagged behind the whole index. If you thought years ago that the Tech sector would be do for a correction and backed out of those 7 companies while keeping the rest, you would be objectively worse off.

You could do what the wealthy will do: wait until your neighbour is really struggling, buy their house for cheap, rent it back to them, and bribe local government to make it easier to evict them when they can't pay.

I'm largely staying out of the stock market, and what I invest I have invested in renewable energy. Most of my savings are in a high interest bank account. Once the economy collapses I plan on investing the money in (green) investment funds, not all at once but buying in gradually month by month while the economy is in panic. That way I don't gamble on any particular moment being the bottom, I just gamble that the economy will not be fucked forever. If it is we have bigger problems.

Sell high, buy low, basically. Except I'm not wealthy enough for the "sell high" part.

Participating in any of it feels dirty, but I'm not in a position to buy myself a house so I guess I have to do something with my savings.

I dumped all of my risky stocks prior to the SpaceX IPO and reallocated my 401k to bonds. Im about 90% bonds at the moment.

On my active trading account I’m in bonds funds like BIL and SGOV and dividend funds like SCHD. I have some individual stocks in relatively safe industries that should bounce back.

You can never predict the future but it feels like a lot of headwinds on a market who’s gains are concentrated in only handful of companies. I’m ok with sitting out for 12 months or until there is some clarity in the market. I have a major renovation going on right now so spending my cash on property improvements is ok with me.

I'm considering moving much of my 401K to the emerging markets equity fund. Not much exposure to AI there.

If you aren't trying to "time the market" why worry about moving things around? Just buy the dip and keep your auto contributions going. It'll come back eventually right?

Check what funds it's invested in, most US or Global indexes/funds will have significant AI/tech exposure as it's so valuable.

Proper investment platforms will have an "x-ray" view that shows you what you actually own between all of your funds, this can be useful to understand what you are currently invested in.

Look for regional or industry specific funds and spread money between them. (You want quite a few if your doing this to spread risk)

Bonds (loans for countries and big companies) are traditionally safer and drop less in recessions, however many governments are already in a lot of debt and the risk of another bank crisis could effect their value significantly. Bonds also lose value when interest rates go up, so if inflation continues to go up they become dangerous too.

Cash is fine unless your bank goes bust, and if it's that tits up, do you trust your government's deposit guarantee?

Gold can be ok short term, but it's already up a massive amount and could drop like a stone if things DON'T go bad.

Nothing is foolproof, otherwise everyone would be doing it, best is to spread your risk so your not all in on something.
