What does the asterisks symbol * on a stock mean?
BSE uses the asterisk symbol (*) next to the stock name to indicate that it is undergoing an open-market buyback. NSE doesn’t follow this practice.
For details on ongoing buybacks, see Zerodha bulletin .
If you wish to participate in an open market buyback, see How do I participate in an Open Market Buyback? How is it different from a normal buyback?
