ETF Blindness

Also: ETF-Blindheit

ETF blindness (German: ETF-Blindheit) describes the state in which investors, by holding a few broad ETFs, accumulate exposure to hundreds or thousands of individual securities without being able to see what they actually own, why it is performing the way it is, or how it could be improved. Apparent diversification replaces actual control. Portfolio DOC dissolves ETF blindness by documenting, justifying, and individually steering every position.
