Quote from Butterball:
You're wrong.
You asserted markets were random and market returns mirror random coin flips. That implies a perfectly efficient and random market that doesn't allow any extraction of alpha. How can edges exist when market returns are perfectly random as you claimed? That is a blatant contradiction.
Either you have to retract your theory that market behavior can be modeled with coin flips or you have to admit that market benchmarks can't be beaten. You can't have both.
I disagree. market returns can be random, yet some can find an structural edge to exploit, or simply get lucky. Can one extract alpha from a casino? if the average is most lose.....Clearly, some people do. Individuals extracting alpha does not mean they were not simply lucky in being at the right place at the right time within an efficient system.
If you have 50 bettors and they all keep betting on a coin flip, one will eventually emerge as the winner, therefore said to have "alpha" in that time series of bets. This winner clearly beat the "average" returns of the others. It's all relative which takes us back to my initial point.
Good Luck!
