- This book popularized the ideas that the stock market is efficient and that its prices follow a random walk.
- For example, the path taken by an individual molecule in a gas is very well modeled as a random walk, entirely probabilistic in its nature.
- Much later Donsker gave a full proof of the convergence of random walks to Brownian motion.
- This means that these variables follow random walks, but they could be related to each other in meaningful long-run relationships.
