This is a passive ETF that tracks a proprietary index selecting non-US large- and mid-cap stocks with solid financials, favorable growth prospects and strong fundamentals relative to share price. It adjusts the weighting between growth and value depending on market conditions.

It suits international diversification investors who want to spread money across developed-market stocks outside the US on a quality basis and are willing to accept currency risk.

It is a passively managed (index-tracking) ETF run by American Century.

The fund tracks a proprietary index that combines financial soundness, growth prospects and fundamentals relative to share price among developed-market large- and mid-cap stocks excluding the US. It focuses on companies that are relatively large and less volatile, and it tries to manage risk by shifting weight between growth and value depending on market conditions.

• International stock selection combining quality, growth and value
• Risk management through adjusting growth and value weightings

Assets under management (AUM) stand at $758.8M, and the total expense ratio is 0.34% per year.

Unlike market-cap-weighted international ETFs, this fund selects stocks on quality criteria, so its performance can diverge from the market, and relative returns vary depending on how favorably quality stocks are viewed.

International quality stocks are affected by each country's economy, exchange rates and preferences for quality and style. They can perform relatively steadily when quality is in favor or volatility is high, but they may lag when risk appetite is strong or the dollar is strengthening sharply.

Money tends to flow into quality international ETFs when interest in international diversification and quality investing rises, and inflows may slow relatively when preference for US stocks or dollar strength intensifies.

Its strength is diversification across developed markets outside the US on a quality basis, while currency exposure, style deviation and regional risk are its drawbacks.

The TOLL, OEFA and WBIL shown in the table invest in durable quality, international quality dividend and active quality strategies, and their selection methods differ. For more exposure to international quality, you can also compare IQLT (international quality), EFG (developed-market growth) and VEA (broad developed markets). They differ in selection criteria, style and fees, so it is best to choose according to your investment profile.

These are the points to review before investing in QINT. As an international quality ETF, it is important to check currency exposure, style deviation, regional risk and fee level in advance.

Exposure to multiple currencies means returns converted into Korean won can swing with exchange rates, and quality-based selection can create performance gaps versus market-cap-weighted benchmarks. Exposure to each country's economy and policy uncertainty should also be considered.

It is a passive ETF suited to international diversification investors who want to spread money across developed-market stocks outside the US on a quality basis. If you want simple market-cap weighting, a general international ETF may be the better choice, and if you want quality-based diversification, QINT can be an alternative.
