International stocks & currency risk

An overseas investment's return to a home-currency investor includes both the security's local-market performance and the currency exchange-rate change, less costs and taxes. A currency gain can help or hurt. Currency hedging can reduce some foreign-exchange exposure, but it costs money, may be imperfect, and changes the portfolio's risk profile.

International companies can operate globally, and home-market companies can earn foreign revenues, but company revenue exposure is not a complete substitute for owning foreign markets. Country and sector weights, accounting standards, market hours, liquidity, capital controls, and political or governance risks vary.

A total-world fund, a developed-markets fund, an emerging-markets fund, and a regional ETF have different coverage and concentration. Check the index methodology, country weights, top companies, foreign-currency exposure, domicile, securities-lending policy, expense ratio, and tracking difference. The label “international” does not guarantee broad global representation.

Foreign dividends may face withholding taxes, and the ability to claim a credit or treaty benefit depends on account type, fund domicile, country, and personal tax circumstances. American depositary receipts (ADRs) represent foreign shares through a depositary structure; they can involve fees, currency conversion, custody, local-market, and regulatory risks. Read the deposit agreement and disclosures.

• Know which countries and emerging markets the fund includes or excludes.
• Distinguish unhedged currency risk from hedged share classes.
• Check trading hours, spreads, tax treatment, and any foreign ownership restrictions.
• Treat foreign exposure as diversification, not a guaranteed hedge or short-term forecast.
