What 89stocks is, who runs it, and what it is not.

89stocks is a research terminal for Indian equity markets, built on proprietary analytics engines and backed by an AI verification layer. It synthesises publicly available financial data, including exchange filings, quarterly results, ownership histories, peer comparisons, and price action, into structured, citation-backed analysis notes.

The flagship product is the Deep Dive: type any NSE or BSE ticker, get a twelve-section institutional-grade briefing in under a minute. Around it sit a cyclical scanner for trough-of-cycle setups, a seasonal scanner for calendar-based patterns backtested over sixteen years, and an in-house undervaluation engine with an AI red-flag check on every top pick.

Every verdict is logged forward and scored against what actually happens, so the platform holds itself accountable for its own calls over time. We do not manage your money. We do not execute trades. We do not hold custody of any funds or securities. 89stocks is a research tool: the equivalent of a fast, opinionated analyst who shows their work.

89stocks is built and operated by Tatsat Shah as a sole proprietorship based in India. Founded in 2026.

Product, analytics, infrastructure, and support all run through one operator directly. Replies to tatsat@89stocks.com land with Tatsat.

• Not a SEBI-registered investment advisor. 89stocks does not provide personalised investment advice and is not authorised to do so under SEBI (Investment Advisers) Regulations, 2013.
• Not a SEBI-registered research analyst at the time of writing. All output is positioned as educational and informational research, not formal research analyst recommendations under SEBI (Research Analysts) Regulations, 2014.
• Not a broker, depository participant, or custodian. We do not place trades on your behalf, hold your money, or have access to your demat account beyond the optional read-only quote feed you authorise yourself.
• Not affiliated with any listed company, broker, or exchange. Coverage decisions and analysis outputs are independent.

Output is produced by our proprietary analytics engines and verified by a layered AI judgement check. It will be wrong sometimes. Markets carry risk. Past patterns do not guarantee future returns. Treat every output as a starting point for your own work, never as a final answer.

All input data comes from publicly available sources. No third-party data vendor is involved in the pipeline. No leaked, paid-private, or proprietary information is used.

Optional broker connection ("bring your own account") is read-only and uses your own broker entitlement, so your live quotes are served to you alone and never redistributed to other users.
