SENSEX

Sensex, officially known as the S&P BSE Sensex, is a stock market index that tracks the performance of 30 of the largest and most actively traded companies listed on the Bombay Stock Exchange (BSE). The name is a portmanteau of "Sensitive" and "Index," coined by analyst Deepak Mohoni in 1989. Launched in 1986, the Sensex is widely regarded as the benchmark indicator for the Indian equity market and is the oldest stock index in India. It uses a free-float market capitalization-weighted methodology, which means only shares available for public trading are considered, and larger companies have a greater impact on the index value. The base year for the Sensex is 1978–79, with a base value of 100. Sensex serves as a crucial barometer of the Indian stock market and economy, reflecting the overall health and direction of the market. Its movements are closely watched by investors, analysts, and policymakers both in India and internationally
