### Comment:
Ehhhh... Pretty sure it's about picking stocks at random. It's all about if you were to 'take a random walk down Wall Street, picking stocks at random'. He definitely doesn't say stock prices move at random, just that there's no hope on predicting where they're gonna go (which obviously a lot of cautious investors all say).

### REPLY:
That's not what random walk means. Random walk is not referring to picking stocks at random. It is a mathematical concept about random changes in a system of integers or steps. The stock price is on a random walk, not you as a buyer.
