Established Markets Are Mostly Efficient.
Established markets — public equities, IG bonds, and major FX — are optimized systems designed to erase mispricing. High-frequency algorithms and institutional coverage ensure that any informational edge collapses instantly.
In these environments, "alpha" is often just beta rebranded or luck back-dated. Once an asset class matures into ETFs and passive indexing, the discovery premium vanishes. Capital density kills outperformance. Sustainable edge does not exist where markets are optimized; it exists only where optimization is absent.
