Sure some might actually be able to move markets with big positions or exploit insider information, but basically everybody playing in the Great Casino is just gambling. It's not a new original point, but with enough people gambling some will have extended winning runs, convincing themselves in the process that they are truly excellent gamblers. Helps a bit if the ATM next to the roulette table regularly spits out free money from the Fed, Treasury, or the deposits and investment accounts of your clients to let you keep on doubling down.
Until you lose of course.
