Introduction: What Are Stock Market Indices?
Indian Stock Market Indices are essential tools for understanding the performance of the market. In India, major indices like Nifty 50 and Sensex offer valuable insights into how the market is doing.

What Are Stock Market Indices?
A stock market index is a statistical measure of the performance of a group of stocks. Indices are a great way to gauge how well the stock market or specific sectors are performing. They represent the collective performance of a selected group of stocks.
When the index moves up, it typically indicates the market is doing well. Conversely, when it drops, it signals that the market is underperforming.

India has several important indices, but Sensex and Nifty 50 are the most widely followed. These indices give investors a quick overview of the performance of the broader market. Additionally, there are sector-specific indices, such as Nifty Bank and Nifty IT, which focus on specific sectors.
Let’s explore the major indices in more detail:
