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 76 positions; VGT draws it from an index that also covers mid and small caps, which gives 316. All 75 of XLK's companies are in VGT, so 100.0% of XLK's weight is shared, and 86.7% of VGT's.

What the 241 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 13.3% of VGT. The gap between 83.9% and full overlap is 16.1% of weight; the tail accounts for 13.3% of it and weighting for the rest, since Nvidia and Apple are heavier in VGT than in XLK. The ten largest positions are 59.4% of VGT and 64.6% of XLK.

Returns that differ by window, risk that does not

Over the past year XLK returned 27.7% against 25.2% for VGT; over three years VGT led at 134.8% against 126.6%; over five years XLK led again at 137.2% against 127.8%. Volatility was 23.4% against 24.0% and the worst falls -25.6% against -24.0%, with betas of 1.55 and 1.56 against the S&P 500.

Correlated at 0.99

Weekly returns correlated at 0.99 over three years and 0.99 over five, about as close to one as two different funds get. Owning both is one technology position of 317 companies, with the small caps at half the weight VGT alone would give them.
