Nifty serves as an essential benchmark for the Indian equity market and is widely used by investors and fund managers to assess market performance.

SENSEX

Similar to Nifty, the SENSEX is used to track the performance of the Indian stock market and serves as a barometer for investor sentiment.

Purpose: Like Nifty, the SENSEX is a vital tool for assessing the Indian stock market's performance. By being a representative of the top 30 companies, it provides valuable insights into the market. The SENSEX is widely reported in both domestic and international markets, making it an essential tool for monitoring market trends.
