The Verdict
IDEV and SCHF are close to the same fund wearing different labels. Both sit in the International Developed category and their daily returns move almost identically, so this is not really a question of which fund is better — it is a question of which one is cheaper to own and easier to trade in your account. Everything below is about finding the small, structural edges, because the investment exposure is a wash.
On ETFValuer's overall model — which blends return, risk-adjusted performance, cost, drawdown, size and volatility — SCHF scores higher: 80.4 (Grade B+) versus 72.3 for IDEV. That doesn't make IDEV a bad fund; it means SCHF 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
On cost, the two are essentially tied — IDEV charges 0.04% a year versus SCHF's 0.03%. A difference this small (about $1.00 a year on a $10,000 position) isn't a reason to choose one fund over the other. That matters more than usual here: when two funds track the same exposure this closely, fee is normally the whole argument — and with the fees this close, there is no argument left. Liquidity and whichever one trades commission-free in your account become the tiebreaker.
What IDEV's Fees Cost You
IDEV charges an expense ratio of 0.04% a year, deducted automatically from the fund's value. Small percentages compound into real money — adjust the figures below to see the impact on your own numbers.
Assumes a constant gross return and no additional contributions — a simplification, but it isolates exactly what the expense ratio costs. Try the full fee calculator to model contributions and compare any two funds.
Performance & Risk
Over the trailing 3 years, SCHF returned +61.51% versus +55.61% for IDEV — a gap of about 5.9 percentage points. On risk, SCHF has held up better historically, with a shallower max drawdown (-13.41% vs. -13.41%). SCHF currently has the better risk-adjusted return (Sharpe ratio of 1.07 vs. 0.87), 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), IDEV and SCHF show a extremely high correlation of 0.986 — very close substitutes. Holding both would add very little diversification: when one falls, the other almost always falls with it. Treat these as alternatives to each other, not as complements in the same portfolio.
| Measure | Value | What it means |
|---|---|---|
| Daily return correlation | 0.986 | Extremely high — very close substitutes |
| R-squared | 97.2% | 97.2% of IDEV's daily moves are explained by SCHF's |
| Tracking error (annualised) | 2.66% | Typical yearly spread between the two funds' returns |
| Annualised return over 3.0y | IDEV +16.23% · SCHF +17.59% | SCHF ahead by 1.37 points a year |
Correlation alone understates how far these can drift. Across every rolling 12-month window in the period, IDEV finished as much as +1.8 points ahead of SCHF at the best extreme and -9.9 points at the worst — a 11.7-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
IDEV and SCHF hold 6 of the same companies among their top 10 positions. Those shared names make up 5.8% of IDEV and 5.7% of SCHF. That's meaningful duplication. The funds aren't interchangeable, but a good share of your money would be riding on the same companies twice.
| Shared Holding | IDEV Weight | SCHF Weight |
|---|---|---|
| HSBC HOLDINGS PLC | 1.09% | 1.08% |
| Roche Holding AG | 0.99% | 0.99% |
| ASTRAZENECA PLC | 1.01% | 0.93% |
| Novartis AG | 0.97% | 0.97% |
| ROYAL BANK OF CANADA | 0.87% | 0.90% |
| SHELL PLC | 0.90% | 0.80% |
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 IDEV if…
- It has been the calmer ride (15.1% volatility vs 17.2%)
Lean SCHF if…
- You want the lower running cost — 0.03% vs 0.04%, about $1 a year less on a $10,000 position
- You care about return per unit of risk — its Sharpe ratio of 1.07 beats 0.87
- You weight recent results heavily — it returned 61.5% over 3 years against 55.6%
Whichever you pick, holding both at full weight is usually the wrong answer — see the overlap and correlation sections above.
