random walk isn't picking stocks at random, but rather that the price movement of a particular stock is random

 but it really isn't. there has been a ton of dissent about that book. not least the fact that firms consistently have traders that gain in the long term above the stock market.

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).
