Well if you were following sound financial advice and understand the economics from an Austrian perspective you'd likely be diversified into several equal buckets with one of those buckets designed to offset the losses. You do this when it doesn't matter because you can never time the market. No one can.

In the case of inflation/stagflation it would be physical assets that increase in value under such circumstances. Gold/Silver meet this, as do many other assets. Under such environments counterparty-risk must be carefully evaluated.

All of your mentioned standard strategies have opaque and significant banking counter-party risk. There are also details such as the YTM loophole where the assets you hold may not have been marked to market (when interest rates go up).

This is particularly true of any bonds, or bond backed securities, and the leverage involved in many such markets is next to impossible to discern, and as a result the average advice of passive investment breaks down towards losses in the near term but not long-term.

None of this is financial advice, just reiterating things people should already know about. The stock market's synthetic share problem coupled with dark pools, and the commodity market's (COMEX) fail to delivers and failure to loadout (physical delivery), are things to know about. Unspecified risk from bad actors.

Its all paper with substantial counter-party risk until you hold it in your hands.
