Price Discovery
The process by which the interaction of buy and sell orders produces a price that reflects the market's aggregate view.
How it is identified
Test: price emerges from competing orders rather than being set administratively or by a single participant
Unit
qualitative
In depth
Price discovery is the exchange's core social function: it aggregates information dispersed across thousands of participants into one number that no individual possessed. It works better where participation is broad, information is disclosed and trading is continuous, and degrades badly in thin, closely held or circuit-locked securities. A price is not a truth claim — it is the point where the marginal buyer and marginal seller happened to agree, and it can be wrong for long stretches. Where price discovery is absent, such as in unlisted shares or a locked circuit, the quoted number carries very little information.
Worked example
A stock locked at the lower circuit with no trades has no price discovery that session: the quoted price is a band limit, not an agreement. The next session's opening auction is where discovery actually resumes.
Illustrative figures, chosen so the arithmetic is easy to follow. Not a live price and not a valuation of any company.
Educational reference only
This entry explains what “Price Discovery” means. It is not investment advice and not a recommendation to buy or sell any security. Any numbers above are illustrative, not live prices, and nothing here predicts price direction or rates a stock. Consider your own circumstances and consult a SEBI-registered investment adviser before acting.
