You can still make quantitative predictions with uncertainty. Note that beating the market isn’t impossible (someone has to make the market efficient) and even if you don’t have enough data to beat the market, that just means you make your confidence intervals larger. The point of Bayesian epistemology is that even large uncertainty can be quantified.
