Most retail investors in India make decisions based on tips, social media, and gut feeling โ not data.
QuantAlpha fixes that.
It is a free, no-login, fully browser-based stock intelligence platform that gives any investor โ whether they're just starting out or have years of experience โ the same analytical toolkit used by professional fund managers. Enter any stock ticker from the Indian (NSE) or US market and receive a complete financial analysis in under 10 seconds.
No Bloomberg terminal required. No expensive subscription. Just a ticker and a browser.

- ๐ Retail investors in India tired of making decisions without proper analysis
- ๐ผ Professionals who want a quick sanity check before investing

A proprietary normalized scoring engine evaluates every company across 5 dimensions:
- Profitability โ ROE, Net Margin, ROA, Gross Margin
- Valuation โ P/E, P/B, EV/EBITDA
- Growth โ Revenue & EPS year-over-year growth
- Financial Health โ Debt/Equity, Current Ratio, Interest Coverage
- Cash Flow โ FCF positivity and FCF growth
Scores are normalized โ meaning if data is unavailable for some metrics, the score is calculated fairly based only on available data. No more artificially low scores due to missing fields.
A two-stage Discounted Cash Flow model estimates the intrinsic value per share using historically observed FCF growth rates, a 10% WACC, and 2.5% terminal growth. Displays full projection table, present values, and margin of safety label.
A collapsible panel on every analysis page explains what each metric actually means for this specific company โ using the real numbers, in plain English. Designed to teach, not just display.
Curated stock lists for 4 proven investment strategies across both US and Indian markets:
- Value Investing โ Low P/E, low P/B, strong FCF
- Growth Investing โ High revenue growth, expanding margins
- Dividend Investing โ Consistent dividend payers
- Quality Investing โ High ROE, strong moats, low debt
Add up to 8 stocks (US or Indian), compare AI scores side by side, view market cap weight distribution, and get a combined portfolio score. Includes 6 preset portfolios across both markets.
