What is the Sensex?
The Sensex, or the S&P BSE Sensex as it is officially known, is the 151 index of the Bombay Stock Exchange (BSE) and a market capitalization weighted index that captures the movement of the stocks of 30 of the largest and most heavily traded companies across India and different industries.
The Sensex is intricately linked with core sectors like IT, banking, pharmaceuticals, energy, and consumer goods, which enables them to draw important conclusions on the economy’s health and sentiment from investors. Thus, the Sensex acts like an investor’s health yardstick and enables them to understand the overall sentiment and the important trends prevalent in the market.
The word Sensex is a blend of the word Sensitive and Index, which in itself gives the importance the index serves in the stock market. As the stock market in India has several indices, the Sensex is the most popular index and is the most referred to index in the stock market news.
The Sensex – Its History and Evolution
The first milestone in the Sensex economy commenced on the 1st of January 1986 at a value of 100 base points. A stock market analyst, Deepak Mohoni, synthesized the index in order to target a dependable benchmark of the Indian stock market. From then, the BSE has been referring to it primarily as the BSE Sensex.
The Sensex, like other indices, has encountered many critical points over the years. July of ‘90 saw the Sensex breach 1,000 points, a milestone that would then see February ‘06 almost effortlessly grace the 10,000 point mark. This greatly displayed the already existing confidence in investors, as well as the economy in India. The recent years saw no difficulty in crossing the 60,000 point milestone.
The index composition has evolved significantly since its inception. The Sensex imposes strict criteria such as market capitalisation, trading volume, and financial performance to determine which companies can enter and exit the index. As such, this dynamic characteristic ensures the index remains representative of the top companies in India.
Understanding the Calculation Methodology
Base Year and Base Value
The Sensex is pegged to the year 1978-79, and the base value for it is 100. This foundation enables the investors to evaluate the market for the long periods and for long periods. The selection of this year corresponds with the year of the first major economic reforms in India, which is why it is chosen.
Free-Float Market Capitalization
The index operates with a methodology of free-float market capitalisation, which only takes into account the shares offered for public trading. This method is specifically designed to more accurately reflect the capital market sentiment as it removes the shares owned by promoters, the government, and other strategic investors.
The calculation is performed by taking the free-float shares of a company and multiplying it by the current market price of each share, together with a proportionate movement of the total. The companies that are more highly capitalized, that is, have a larger market capitalisation, have a larger impact and weigh more for the movements of the index.
Index Maintenance and Adjustments
The relevance and representation of Sensex is maintained through regular updates, which index committees do every quarter, along with reviewing composition, taking into account the rankings, trading activity, and representation of sectors of companies in the market. Automatic adjustments to price continuity are maintained for stock splits, stock bonuses, and stock spin-offs.
Factors Influencing the Sensex
Macroeconomic Factors
The level and growth rate of GDP, inflation rate, interest rate, and government fiscal policies have a considerable bearing on the performance of the Sensex. Strong fundamentals and the economy drive the index appreciation, while uncertainties in the economy lead to volatility.
Policies of government spending with relation to taxation, domestic market, and foreign investment with regard to regulation all affect the sensitive movements of the market. There are also budget announcements, payments, forthcoming monetary policies with the Reserve Bank of India, and structural policies of the government that lead to great movements in the market.
Global Market Trends
The advancement and evolution of foreign and external markets affects the Sensex and more so in recent times, because of India’s integration into the world financial markets. Investments from foreign institutional investors, along with other global commodity prices and other international events, have a cascading effect on the Indian markets.
In particular, the movement of the dollar and international markets, along with the USD INR exchange in the Indian markets, has a high bearing on the international bound companies. The globally spread abnormal conditions, along with the global recession and geopolitical movements, coupled with trade and other international relations tensions, can lead to a movement in the emerging markets, and more so with India.
Company-Specific News and Events
The financial performance of individual companies listed in the Sensex has a bearing on the performance of the index as a whole. Changes in the corporate governance structure, mergers and acquisitions, along with the performance indicators of the entities, tend to impact stock prices and thus the index levels.
With only 30 companies listed on the Sensex, movements in stock prices of Reliance Industries, TCS, or HDFC Bank would greatly affect the index. Because of the concentration effect, the stock price movements of these companies make the developments in their fundamentals highly relevant in evaluating and forecasting the performance of the index.
Liquidity conditions prevailing in the financial systems tend to correlate with market behavior. When the liquidity conditions are very poor, the valuation of the stock index is highly sensitive to the inflow of foreign portfolio investments.
