"Pick a diverse basket of unhyped, sane stocks" sounds like "my trading strategy" because it's not at all specific or repeatable. It also just sounds like a homemade index fund that never rebalances.

In gambling, a few people beat the house. That's a guarantee of probability. In aggregate, the house always wins.
