  1. Stock markets cannot be truly random as long as people without understanding of statistics are buying any meaningful amount of stocks. I've been thinking for years that stock markets are about betting about what other people believe to be correct value for the stocks in the future. There's a lot of psychology in that equation and a lot of superstitious behavior (e.g. stock value graph having 3rd spike changes the overall direction of the stock because many enough people believe that 3rd time the charm; similarly, many people believe in special numbers such as 10, 100, 1000 and if stock value ever gets close to those numbers, many enough people suddenly change behavior again).
