The SENSEX, short for "Sensitive Index," is India's premier stock market index, representing the performance of the top 30 companies listed on the Bombay Stock Exchange (BSE). Widely regarded as the benchmark index for the Indian equity market, the SENSEX plays a pivotal role in measuring overall market sentiment and economic health.
History
The SENSEX was first compiled on January 1, 1986, with a base value of 100. The index was initially calculated based on the market capitalization methodology. Over the years, the methodology evolved, and in 2003, the SENSEX transitioned to a free-float market capitalization-weighted methodology, which remains in use today.
Calculation
The SENSEX is computed using the free-float market capitalization of its constituent companies, adjusted for corporate actions such as stock splits, rights issuances, and dividends. The index is calculated in real-time during trading hours and is expressed in points.
Constituent Companies
The SENSEX comprises 30 of the largest and most actively traded stocks listed on the BSE. These companies represent various sectors of the Indian economy, including banking, finance, information technology, pharmaceuticals, and consumer goods. The selection of constituent stocks is based on predefined criteria such as market capitalization, trading volume, and liquidity.
Significance
As India's most widely tracked stock market index, the SENSEX serves as a barometer of investor sentiment and market trends. It is used by investors, traders, analysts, and policymakers to gauge the overall health of the Indian stock market and economy. Fluctuations in the SENSEX often influence investment decisions and can impact market behavior.
Historical Milestones
Over the years, the SENSEX has witnessed several historic milestones and significant movements. Notable events such as economic reforms, budget announcements, global economic developments, and geopolitical tensions have influenced the index's trajectory. The SENSEX has experienced periods of rapid growth, sharp declines, and volatility, reflecting the dynamic nature of financial markets.
Impact on Economy
The performance of the SENSEX is closely linked to the broader economy, as it reflects investor confidence, corporate profitability, and economic growth prospects. Positive movements in the index are generally associated with optimism about the economy, while negative trends may indicate concerns or uncertainties.
