Information and calculation tools by Rachid Asen. Not investment advice or research.

Disclaimer. Information tool. Compiles data published by NSE and BSE and calculations from the exchanges' published ESM and ASM criteria. Prices are end-of-day, not live: updated each evening after trading ends. Ethical business criteria are matched by AI, which can make mistakes; this is a criteria match, not a certification, fatwa, rating or advice. Check the company's filings. Not investment advice, research or a recommendation to buy, sell or hold any security; not SEBI-registered as an Investment Adviser or Research Analyst. Calculated dates are the earliest a security could become eligible; inclusion, stage changes and exit are decided solely by the exchanges. ESM, ASM and GSM shortlisting are surveillance measures and not an adverse action against the company. Data may be delayed or inaccurate; verify with the exchange.
