What the numbers say

One sector, two universes

Both funds hold the information technology sector and nothing else. XLK draws it from the S&P 500, which gives 74 positions; VGT draws it from an index that also covers mid and small caps, which gives 319. All 73 of XLK's companies are in VGT, so 100.0% of XLK's weight is shared, and 87.8% of VGT's.

What the 246 extra companies weigh

Snowflake, Cloudflare, Astera Labs, Credo, Okta, Twilio and MongoDB are the largest positions VGT holds that XLK does not, and with the rest of the small-cap tail they come to 12.2% of VGT. The gap between 81.3% and full overlap is 18.7% of weight; the tail accounts for 12.2% of it and weighting for the rest, since Nvidia and Apple are heavier in VGT than in XLK. The ten largest positions are 62.5% of VGT and 61.4% of XLK.

Returns that differ by window, risk that does not

Volatility was 23.4% against 23.9% and the worst falls -25.6% against -24.0%, with betas of 1.49 and 1.5 against the S&P 500. XLK charges 0.08% against 0.09%, $1 a year on $10,000.

Correlated at 0.99
