The Econ 101 is the complete opposite. Bonds usually have fixed rates, whereas stock prices are in principal tied to revenues, and nominal revenues should increase with inflation--companies increasing prices is literally how most people experience inflation. But Econ 101 also suggests that in the short term things will be more complex than all that because price adjustments won't be instantaneous. Fear and volatility will create demand for bonds, which could offset to some extent the clearly diminishing nominal value of fixed-rate bonds.

Note that a key factor here isn't inflation, per se, but the rate of change in inflation. From an Econ 101 perspective 2% inflation is no different than 20% inflation if things are otherwise steady-state. Stocks are the better bet because in principal they should respond more quickly to changes in the inflation rate. If inflation is steady, bonds in principal are the simpler, cheaper instrument.
