Q: Hi,

I have all of my international equity in XEF with a small amount of VEE. I noticed that IDV has performed extremely well this past year and better than XEF. Can you please explain why?

And are the two different enough that it would make sense to own both or is this too much diversification with both being broad market ETFs?

thanks

Q: Could you give me your opinion on which you prefer out of this list ? If one was to combine 3 or 4 of these what would be a good combination ? You may take more than 1 credit if you wish.

Q: Hi, I was made aware of a gap (The "Korea Gap") in my international ETF strategy based on your ETF Update model portfolios that I believe is worth sharing.

The "Korea Gap" occurs when an investor mixes ETF providers that use different index benchmarks (specifically MSCI and FTSE). Because these two providers categorize South Korea differently, an investor can inadvertently end up with 0% exposure to the world's 10th-largest economy.

MSCI (Used by iShares XEF): Classifies South Korea as an Emerging Market. Therefore, it is excluded from XEF (Developed Markets).

FTSE (Used by Vanguard VEE): Classifies South Korea as a Developed Market. Therefore, it is excluded from VEE (Emerging Markets).

The result is if you hold only XEF and VEE, South Korea effectively disappears from your portfolio!

In 2025, this meant missing out on the massive "HBM (High-Bandwidth Memory) Craze" led by Samsung and SK Hynix, which drove the KOSPI to record highs.

Portfolio Combo | Provider | Where is Korea? | Avg. MER
XEF + VEE | Mixed | Missing (0%) | 0.24%
XEF + XEC | MSCI | XEC (Emerging) | 0.25%
VIU + VEE | FTSE | VIU (Developed) | 0.24%

I'll personally be replacing my VEE with XEC to hold the MSCI Blackrock combination.

In the XEF + XEC combo, South Korea makes up about 12-13% of the Emerging Markets (XEC) slice. In the VIU + VEE combo, it makes up about 5-6% of the Developed (VIU) slice. This means the iShares combo actually gives you a "heavier" bet on Korea.
