Understanding Market Indices: Nifty, Sensex & More

A stock market index is like a scoreboard—it tells you how the market is performing at a glance. But beyond just numbers, indices hold deep insights into market trends, investor sentiment, and economic health. Whether you’re a beginner or an experienced trader, understanding market indices is essential to navigating the stock market with confidence.

What is a Market Index?

A market index is a basket of selected stocks representing a particular segment of the market. These indices track the performance of these stocks to give investors a sense of how the market or a sector is doing overall.

Think of it this way: If you wanted to check how the weather is in a city, you wouldn’t look at just one thermometer—you’d want an average from different locations. Similarly, market indices give a broad picture of market performance rather than focusing on a single stock.
