How the look-through works

An ETF has no fair value of its own like a single stock. We build it bottom up: every holding has a fair value and a quality score on our pages. Weighted by portfolio share, that gives Vanguard Mid-Cap Index Fund ETF Shares an average of how cheap or expensive its companies currently sit versus fair value, and how high their average quality is.
