🚀 Introducing Duothemes: Thematic Research and Alt Data for Independent Investors

Have you ever spotted a thesis gaining momentum in US stocks, but you’re not sure which companies are part of it?

Or a stock suddenly takes off, and you can’t tell which sector is pulling it along?

📈 Stocks rarely move alone. News, industry trends, and capital flows often move a whole group. Instead of chasing the gainers list, look for themes gaining traction—and companies worth researching.

Meet Duothemes, a website built for US equity theme research.

🤖 You might ask, with AI this capable, why not just ask it to analyze stock themes? Why use a dedicated website?

AI helps us find information, understand concepts, and explore ideas. But using that analysis for investment decisions raises three issues:

⚠️ AI can hallucinate.
🔍 AI's analytical framework is not always transparent or consistent.
⏳ AI carries look-ahead bias in backtesting.

In short, AI helps you explore ideas. Duothemes brings that exploration into a stable, verifiable, reusable data framework.

🧭 The danger is not having too few opinions. It is using different standards every time to justify them.

A consistent framework helps distinguish changes in the market from changes in your own method.

That is why I built Duothemes.

📊 Beyond themes, companies, and institutional holdings, the site includes industry-level data:

Theme lifecycle analysis
A free market overview
Financials for AI-related companies
Hyperscaler CDS spreads
GPU rental prices
AI server-component trends
Macroeconomic datasets and analytical tools
Earnings Hunter

These datasets are often hard to find together in a conventional market-data app.

🔬 They help you move beyond what the market is talking about and ask whether the underlying industry is actually improving.

If you research US stock themes but struggle with scattered information, unclear categories, or where to begin, try Duothemes.

There’s still a lot I want to improve, so I’m especially interested in feedback on two things:

💡 What signals would you want before deciding a theme is becoming investable?
🧩 What would make you trust—or distrust—a platform's classification of companies into a theme?

🙏 Thanks for checking it out — and I'd genuinely love to hear how you research investment themes today.
