It's often difficult for me to discuss this since I do automated trading. I've been doing this for over 10 years now, have grown a company out of it that has 30 employees, and I maybe lose money 2 or 3 days out of the entire year and often times due to technical reasons... Either daily movements of stocks are not at all like a random walk, or I am just one heck of an astronomically lucky guy. Now I do consider myself fortunate and privileged, for sure... but the amount of luck it would take to repeatedly make money on the market day after day that can fund a decently sized team of high paying engineers, data center costs/hardware costs, so on so forth... it's unthinkable. The stock market, at least to the degree that I am involved in it, very short term market microstructure, doesn't behave anything like what economists say it does.
