IGV vs VGT: Which ETF Is Better in 2026?

The Verdict
IGV and VGT compete directly — both are Technology funds chasing the same job in a portfolio. That makes this a genuine either/or: the index each tracks, what it costs, and how it has handled drawdowns are what separate them, not the broad exposure they give you.
On ETFValuer's overall model — which blends return, risk-adjusted performance, cost, drawdown, size and volatility — VGT scores higher: 76.0 (Grade B+) versus 34.7 for IGV. That doesn't make IGV a bad fund; it means VGT currently edges it out on this specific mix of factors. Read the metric-by-metric breakdown below before deciding which matters more for your own portfolio.

Bold marks the better value in each row. "Better" is directional only (e.g. lower cost, higher return) — it isn't a recommendation by itself. See the full methodology.
Cost

Performance & Risk

On risk, VGT has held up better historically, with a shallower max drawdown (-27.23% vs. -36.61%). VGT currently has the better risk-adjusted return (Sharpe ratio of 1.18 vs. -0.91), meaning it delivered more return per unit of volatility taken on.
How Closely Do They Track Each Other?
Over the last 3.0 years of daily returns (752 shared trading days), IGV and VGT show a strong correlation of 0.768 — clearly related, with room to diverge. There is some genuine differentiation here, but not enough to call these complementary holdings. Pairing them mostly concentrates risk rather than spreading it.
| Measure | Value | What it means |
|---|---|---|
| Daily return correlation | 0.768 | Strong — clearly related, with room to diverge |
| R-squared | 59.0% | 59.0% of IGV's daily moves are explained by VGT's |
| Tracking error (annualised) | 17.20% | Typical yearly spread between the two funds' returns |
| Annualised return over 3.0y | IGV +6.88% · VGT +26.85% | VGT ahead by 19.97 points a year |
Correlation alone understates how far these can drift. Across every rolling 12-month window in the period, IGV finished as much as +20.9 points ahead of VGT at the best extreme and -71.1 points at the worst — a 92.0-point spread between the best and worst year of relative performance. Two funds can correlate tightly day to day and still deliver very different outcomes over any single year you happen to hold them.
Calculated from daily total returns over the trailing 3-year window, recomputed every day this site refreshes. Correlation of 1.00 means the two funds moved in lockstep; 0.00 means their daily moves were unrelated.
Holdings Overlap
IGV and VGT hold 2 of the same companies among their top 10 positions. Those shared names make up 17.6% of IGV and 11.9% of VGT. That's modest duplication — the funds are mostly distinct at the top, so holding both can still add diversification.
| Shared Holding | IGV Weight | VGT Weight |
|---|---|---|
| Microsoft Corp. | 8.55% | 10.30% |
| Palantir Technologies, Inc. | 9.03% | 1.57% |
Compares the top 10 reported holdings from each fund's most recent SEC N-PORT-P filing, so it understates total overlap — funds tracking similar indexes overlap far more deeply than the top 10 alone can show. Search any company across all tracked funds with the Stock Overlap tool.
Which One Should You Pick?
Lean IGV if…
- You prefer to keep holdings under one roof at iShares
Lean VGT if…
- You want the lower running cost — 0.09% vs 0.39%, about $30 a year less on a $10,000 position
- Current income matters to you — it yields 0.36% against 0.02%
- It has been the calmer ride (23.6% volatility vs 28.9%) with a shallower worst-case fall (-27.2% vs -36.6%)
- You care about return per unit of risk — its Sharpe ratio of 1.18 beats -0.91
Whichever you pick, holding both at full weight is usually the wrong answer — see the overlap and correlation sections above.
