Abstract

We document that investors lack conviction as to what the stock market price should be, absent seeing it. Through experiments, we find that online participants, MBA students, and asset-management professionals cannot identify extreme deviations from market prices. When asked, asset-management professionals and LLMs do not think it is possible to reliably estimate the level of the market within 10\%. This suggests that return expectations and investment decisions are generally made without conviction about the prevailing market price level. We call this price agnostic demand which can help explain a number of puzzling patterns in asset prices.
