What the numbers say

VOO sits inside VTI rather than beside it

The number that matters here is not the 88.1% overlap, it is the asymmetry behind it. Nearly all of VOO, 99.9% of its weight, is inside VTI. Only 88.3% of VTI is inside VOO. VTI is VOO plus a tail: 3483 positions against 504, and the 2981 companies VOO does not hold are mid and small caps that together make up 11.7% of the fund.

The tail has cost about two points in this stretch

That tail is why the two funds are not identical, and also why the difference has been small. Over three years VOO returned 90.4% and VTI 88.6%: smaller companies have lagged large ones over this window, which is a fact about the window rather than about smaller companies. Volatility was 14.2% against 14.4% and the worst fall -16.7% against -17.4%.

What VTI holds that VOO is not allowed to

Where the pair does differ: VTI holds names VOO cannot, because the S&P 500 requires profitability and a committee vote. Snowflake, Cloudflare and Cheniere sit in VTI and not in VOO. The whole US market against the part a committee has admitted is the entire difference, and it weighs 11.7% of VTI.
