The term was popularized by the 1973 book A Random Walk Down Wall Street by Burton Malkiel, a professor of economics at Princeton University, [2] and was used earlier in Eugene Fama's 1965 article "Random Walks In Stock Market Prices", [3] which was a less technical version of his Ph.D. thesis.
Price discovery is a summation of the total market's sentiment at a point in time: a multifaceted, aggregate view on the future. It is how every price in every market is determined.

During the 1930s-1950s empirical studies focused on time-series properties, and found that US stock prices and related financial series followed a random walk model in the short-term. [8] While there is some predictability over the long-term, the extent to which this is due to rational time-varying risk premia as opposed to behavioral reasons ...
