A stock symbol ticker is a unique code assigned to publicly traded companies, serving as their identifier on stock exchanges.
These symbols, commonly called tickers, help investors quickly recognize and track stocks.
For example, TCS represents Tata Consultancy Services on the NSE, while AAPL stands for Apple Inc. on the Nasdaq.
Some exchanges, like the BSE, use numeric codes (e.g., 500325 for Reliance Industries).
