On ESG/SRI: fair, excluding sectors comes at a cost, and we make that trade-off knowingly.

On stock picking: the system is rules-based and mechanical, not discretionary. The "folly" argument applies most strongly to human judgment calls, which this attempts to remove. I literally wanted to reduce bias and get a better vantage point.

On beating the index: 14 years of backtested data with walk-forward validation suggest it's possible for this specific strategy. Whether it holds going forward, nobody knows. We publish the ten best and worst precisely because we're not claiming certainty.
