Consider the following statements: 1. Sensex is based on 50 of the most important stocks available on the Bombay Stock Exchange (BSE) 2. For calculating the Sensex, all the Sensex stocks are assigned proportional weightage. 3. New York Stock Exchange is the oldest stock exchange in the world. Which of the statements is/are correct?

1. Statement 1 is incorrect. The Sensex, the benchmark index of the Bombay Stock Exchange (BSE), is based on 30 prominent stocks, not 50. The Nifty 50 index of the National Stock Exchange (NSE) is based on 50 stocks. 2. Statement 2 is correct. For calculating the Sensex, a free-float market capitalization methodology is used, where stocks are assigned proportional weightage based on their market value available for trading. 3. Statement 3 is incorrect. The New York Stock Exchange (NYSE) was founded in 1792. The Amsterdam Stock Exchange (now Euronext Amsterdam) is older, founded in 1602. Therefore, NYSE is not the oldest stock exchange in the world. 4. Thus, only statement 2 is correct.
