Mark
1. (n) A gullible fool; one easily persuaded of the merits of complex final products, whether or not they have any. A dupe. A patsy. One who instinctively likes the sound of leveraged alpha, and whose residual doubts about it can be easily assuaged by deft backtesting.
2. (n) One who does not answer to Matthew, Luke, John, Arthur or Martha. And that’s the gospel.
