Frequently asked

How much do VO and XLY overlap?

VO and XLY overlap 8.8% by portfolio weight — largely distinct portfolios. They share 25 holdings. The figure comes from current issuer holdings files (VO as of 2026-06-30, XLY as of 2026-07-23).

How is the overlap between VO and XLY calculated?

As the sum of the smaller weight in each fund, over every holding both funds own: Σ min(wA, wB). If VO holds a stock at 6% and XLY holds the same stock at 4%, 4% counts as shared. The result is bounded between 0% and 100%, and it is computed after looking through any fund-of-funds to the underlying holdings.

Is it redundant to hold both VO and XLY?

That depends on your goals — we state facts, not advice. At 8.8% overlap, each fund still contributes meaningfully distinct exposure.

What does VO own that XLY doesn't?
