Weights are fractions of each fund, not of any portfolio. Direct holdings only — a fund-of-funds holding WLK through another fund is not listed here, because it would double-count against the fund it holds.

Which funds hold WLK?

Why do I own WLK if I never bought it?
Index funds hold whatever their index holds. If WLK is in the S&P 500, every S&P 500 fund owns it, and so does every total-market fund, every large-cap fund and most target-date funds — which hold those funds in turn. Owning several funds that each hold WLK means owning it several times over, which is only visible once every fund is looked through to the companies underneath.
How much WLK do I actually own?
That depends on which funds you hold and in what proportion — the weights on this page are fractions of each fund, not of your portfolio. Adding up your own exposure means looking through every fund you own at its current holdings, which is what the free X-ray on this site does.
Are indirect holdings counted here?
No. This page lists direct holdings only. A target-date fund that holds a total-market fund also holds WLK at one remove, but counting that here would double-count it against the fund already listed. The portfolio X-ray resolves those nested funds properly, because it knows how much of each fund you hold.
