The problem: three markets, zero unified tools
You invest across US, Japanese, and Vietnamese markets because you see opportunity that domestic-only investors miss. Toyota trades at 8x earnings while Tesla trades at 60x. Vietnam's GDP is growing 6% annually while developed markets struggle for 2%. You know there is alpha in going global.
But the tooling is brutal. To research a cross-market opportunity, you are juggling Yahoo Finance for US stocks, Kabutan or Nikkei for Japan, and CafeF or VNDirect for Vietnam. Each platform has different data formats, different financial reporting standards, and different currencies. Comparing Toyota's P/E ratio to Tesla's requires you to manually convert between US GAAP and Japanese GAAP reporting. Comparing Vinfast's valuation to either requires navigating Vietnamese accounting standards.
The currency layer adds another dimension of complexity. Is that Japanese stock cheap, or does it just look cheap because the yen weakened 15% this year? Is your Vietnamese position up 20% in VND but only 8% in USD terms? Most investors do this math in spreadsheets, if they do it at all.
The solution: one conversation, every market
Journely pulls real-time and fundamental data from US, Japanese, and Vietnamese exchanges and normalizes it into a single analytical framework. Ask a question in English, and get an answer that spans all three markets with consistent metrics, currency-adjusted comparisons, and market-specific context.
No tab switching. No manual currency conversion. No reconciling different data sources. Just ask what you want to know.
- Normalized financial data. Journely adjusts for differences in reporting standards so you can compare a US company's margins to a Japanese or Vietnamese company's margins on equal footing.
- Real-time currency awareness. Every comparison factors in current exchange rates. See returns in USD, JPY, or VND -- or all three side by side.
- Market-specific context. Journely understands that Vietnamese market hours, settlement rules, and foreign ownership limits are different from US markets. It factors this into its analysis.
- Cross-listing detection. For companies listed on multiple exchanges (like Vinfast on NASDAQ), Journely can compare valuations across listings and flag arbitrage-relevant discrepancies.
What a real conversation looks like
Here is how an overseas Vietnamese investor based in Tokyo uses Journely to evaluate an automotive investment thesis across three markets.
Three very different companies at three very different stages. Here is how they stack up:
Toyota (7203.T) -- The profit machine
Market cap: 42.8T JPY ($285B USD). P/E: 8.4x. Dividend yield: 3.1%. Revenue grew 12% last year driven by hybrid demand. Net margin: 8.9%. They produce 10M+ vehicles annually and generate massive free cash flow. Trading near historical lows on valuation despite record profits. The yen weakness makes their exports even more profitable.
Tesla (TSLA) -- The growth bet
Market cap: $780B USD. P/E: 62x. No dividend. Revenue growth slowed to 8% as EV competition intensified. Net margin: 9.2% but declining from 15% two years ago. Deliveries of 1.8M vehicles last year. The valuation prices in massive future growth from autonomy and energy storage, not just cars.
Vinfast (VFS) -- The emerging play
Market cap: $9.2B USD. P/E: negative (not yet profitable). No dividend. Revenue of $1.8B with deliveries of 77K vehicles. Burning approximately $600M per quarter. The thesis is Vietnam and Southeast Asian EV adoption. Parent company Vingroup provides financial backing, but the path to profitability is still unproven.
The key contrast: You can buy Toyota at 8x earnings with a 3% yield, Tesla at 62x earnings for its growth potential, or Vinfast at a pre-profit stage for emerging market EV exposure. These are fundamentally different risk-reward profiles.
Given that you are heavy in US tech, the diversification math favors Toyota. Here is why:
Correlation factor: Tesla correlates 0.72 with the NASDAQ -- it moves with your existing tech holdings. Toyota correlates only 0.18 with NASDAQ. Adding Toyota actually reduces your portfolio's overall volatility. Vinfast at 0.31 is in between but with much higher standalone volatility.
Currency diversification: Toyota gives you JPY exposure. With the yen near 30-year lows against USD, you are buying Japanese earnings at a discount. If the yen reverts even partially, you get a currency tailwind on top of the equity return.
Income component: Toyota's 3.1% dividend yield is paid in yen but converts to meaningful USD income. Tesla and Vinfast pay nothing.
My assessment: Toyota is the strongest diversifier for a US-tech-heavy portfolio. If you want emerging market auto exposure specifically, consider a small Vinfast position as a satellite holding alongside a larger Toyota core position.
Currency-adjusted returns matter more than you think
A stock that gains 15% in local currency but loses 10% on the exchange rate only returned 5% in your home currency. Journely automatically calculates and displays currency-adjusted returns so you always know your real performance, not just the headline number.
Built for investors who think globally
- US, Japan, and Vietnam market data. Real-time quotes, fundamental data, and technical analysis across all three markets. More markets coming soon.
- Cross-market sector analysis. Compare the semiconductor industry across US (NVDA, AMD), Japan (Tokyo Electron, Renesas), and Vietnam (FPT) in a single query.
- Foreign ownership tracking. Vietnamese stocks have foreign ownership limits. Journely flags when a stock is approaching its FOL so you do not get blocked from buying.
- Multi-currency portfolio view. See your total portfolio value in any base currency. Understand how currency movements impact your overall returns.
- Market hours awareness. Journely knows when each market is open and factors in pre-market, post-market, and overnight session data where relevant.
Why these three markets?
The US offers the deepest, most liquid equity market in the world. Japan offers value opportunities in world-class companies that Western investors overlook. Vietnam offers frontier-market growth rates with improving market infrastructure. Together, they cover developed, mature, and frontier market exposure -- a powerful combination for long-term wealth building.
