How to Analyze International Stocks (Europe, Asia & ADRs)
Most investors know how to analyze international stocks in theory — it's the same fundamental analysis they'd apply at home. In practice, the moment you look past US markets, three things get harder: finding reliable financial data, choosing between multiple listings of the same company, and reading valuation ratios that mix two different currencies. This guide covers all three, so a French luxury house or a Hong Kong tech giant gets the same rigorous treatment as any S&P 500 name.
The payoff is real. The US is roughly 60% of global market capitalization, which means an all-US portfolio ignores nearly half the world's public companies — including dominant businesses in semiconductors, luxury goods, pharmaceuticals and banking that simply don't have an American equivalent. International diversification also spreads your exposure across economic cycles and currencies instead of tying everything to one economy.
The same 10 criteria apply everywhere
Here's the most important thing to internalize: a good business looks the same in every country. Revenue growing above 10% a year, P/E below 25, PEG below 2.0, ROE above 5%, operating margin above 10%, ROA above 5%, quick ratio above 1.5, debt-to-equity below 1.0, positive free cash flow yield — these thresholds don't care whether the company reports in euros, pounds or Hong Kong dollars. Accounting standards differ in the details (IFRS in Europe versus US GAAP), but the underlying questions — is it growing, is it profitable, is it safely financed, is it reasonably priced? — are universal.
That's why the full research process from our guide on how to research a stock before buying transfers directly to international stocks. What changes is where the numbers come from.
How to analyze European stocks: the data comes from ESEF filings
For European companies, the gold standard is the company's own annual report. Since 2021, EU-listed companies must publish their annual financial reports in ESEF (European Single Electronic Format) — a machine-readable XBRL format — and the UK has its equivalent, UKSEF. These filings are collected in public repositories, which means the revenue, margins, debt and cash flow of a company listed in Paris or Amsterdam can be read straight from the official audited numbers, not scraped from a third-party summary.
This matters because free data coverage for European stocks is notoriously patchy: many popular screeners only carry US listings, or show stale or incomplete fundamentals for anything with an exchange suffix. When Stoxly analyzes a European ticker like MC.PA (Paris), ASML.AS (Amsterdam) or SHEL.L (London), it pulls fundamentals from these official ESEF/UKSEF filings where available and runs the exact same 10-point score it uses for US stocks. Coverage isn't perfect — some countries publish less to the public index than others — but when the filing exists, you're working with the audited source.
Chinese stocks: ADR or Hong Kong listing?
Many large Chinese companies trade in two places: on the Hong Kong exchange (a .HK ticker like 9988.HK) and in the US as an American Depositary Receipt (ADR) — a US-listed certificate representing shares of the foreign company (BABA for the same business). Fundamentally it's the same company either way, so which listing should you analyze and buy?
For most investors, the US ADR is the more practical choice when one exists:
- Better data coverage. US listings are covered by far more data providers, so fundamentals, estimates and news are easier to find and more complete.
- Higher liquidity and easier access. Major ADRs trade with deep volume during US hours, and most brokers charge less for US trades than for Hong Kong ones.
- USD pricing. No board-lot rules or HKD conversion to think about.
The ADR isn't automatically superior — ADRs carry their own structural considerations, and not every Hong Kong-listed company has one. But if you type a Hong Kong ticker into Stoxly and a US dual listing exists, it will point you to the ADR's analysis, because that's usually where the data is richest.
Mind the currency: when ratios can mislead
Currency is the quiet trap in international analysis. Price-based ratios — P/E, price-to-sales, price-to-book, dividend yield, FCF yield — divide a market price in one currency by fundamentals reported in another. If the share trades in pounds but the company reports in dollars (as some large UK-listed multinationals do), naively dividing the two produces a number that's simply wrong.
The fix is discipline: only trust a price-based ratio when price and fundamentals are in the same currency, or have been properly converted. Stoxly handles this conservatively — when the listing currency doesn't match the filing currency, it marks those ratios as unavailable rather than showing a misleading figure. Profitability and balance-sheet ratios (ROE, margins, debt-to-equity, quick ratio) are immune, because both numerator and denominator come from the same filing.
Currency also affects your returns: a stock can rise 10% in euros while the euro falls 10% against your home currency, leaving you flat. That's a portfolio consideration, not a stock-quality one — but know it exists.
Putting it together
Analyzing international stocks isn't a different discipline — it's the same fundamentals-first process with two extra questions: which listing? and which currency? Judge the business with the same ten checks you'd use at home, be skeptical of price ratios that mix currencies, and prefer the listing with the best data and liquidity. And as always, valuation deserves special care across borders — European markets often trade at structurally lower multiples than the US, so read our guide on how to tell if a stock is overvalued before assuming a low P/E abroad is a bargain. If you're still deciding between studying the business and studying the chart, fundamental vs technical analysis explains why fundamentals win for long-term decisions — in every market.
FAQ
Should I buy the ADR or the foreign listing?
If a liquid US ADR exists, it's usually the more convenient choice: better data coverage, deeper trading volume, lower broker fees and USD pricing. The underlying business is identical either way, so the decision is about access and cost, not quality. If no ADR exists, buying the local listing through a broker with international access works fine.
Do the same valuation ratios work for European and Asian stocks?
Yes — P/E, PEG, ROE, debt-to-equity and the rest measure the same things everywhere. Two caveats: make sure price-based ratios use a single currency, and remember that different markets carry different typical multiples, so compare a company against its regional peers as well as against absolute thresholds.
Can I analyze non-US stocks with free tools?
Increasingly, yes. European fundamentals are published in machine-readable ESEF/UKSEF filings, and Stoxly reads them directly to score tickers with suffixes like .PA, .AS, .L and .HK with the same 10-point framework as US stocks. Coverage varies by country, so expect the occasional "N/A" — an honest gap beats a wrong number.
