Webb18 jan. 2024 · Random walk theory is a practical tool and has proven correct in many cases. Thus, it suggests people not waste money hiring fund managers to handle their portfolios. If some fund managers could provide better returns than the broader market, it could be due to luck, and it’s tough to sustain in the long run. Basic Assumptions of ... WebbAnother hypothesis, similar to the EMH, is the Random Walk theory. Random Walk states that stock prices cannot be reliably predicted. In the EMH, prices reflect all the relevant information regarding a financial asset; while in Random Walk, prices literally take a ‘random walk’ and can even be influenced by ‘irrelevant’ information.
