Frequently asked

How much do SMH and VGT overlap?

SMH and VGT overlap 42.2% by portfolio weight — moderate overlap. They share 20 holdings. The figure comes from current issuer holdings files (SMH as of 2026-03-31, VGT as of 2026-06-30).

How is the overlap between SMH and VGT calculated?

As the sum of the smaller weight in each fund, over every holding both funds own: Σ min(wA, wB). If SMH holds a stock at 6% and VGT 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 SMH and VGT?

That depends on your goals — we state facts, not advice. At 42.2% overlap, each fund still contributes meaningfully distinct exposure.

What does SMH own that VGT doesn't?

SMH holds 26 positions and VGT holds 322; 6 of SMH's positions don't appear in VGT at all, and they are 19.8% of SMH by weight.
