I would argue that parts of the economy should (hopefully) remain healthy. I mean, AI bubble or not, people need medicine, food, internet access, energy, ... . Invest in that.

Also (not a financial advisor), when a crash occur there is a so called "flight for quality" where people move money they made by cashing out the assets to stable (A+ assets). So look for companies that have solid financials and can weather the storm.

Finally, diversify not only on the industry, but also geographically. EU, Swiss, Asian. I personally stay a bit away from emerging markets stuff as I don't have enough knowledge to make informed decisions (I don't even consider Emerging Market ETFs which should be run by SMEs).
