Sensex and Nifty are India&#8217;s two most widely followed indices, representing the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE), respectively. They help investors assess market trends, compare returns, and make informed investment decisions.<\/p>\n\n\n\n<p>In this blog, we will explore what Sensex and Nifty are, how they function, their key differences, and which index is more relevant for investors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is Sensex?<\/strong><\/h2>\n\n\n\n<p>The Sensex (Stock Exchange Sensitive Index) is the Bombay Stock Exchange (BSE) benchmark index.
