Further, in the next section, throwing some light on how to calculate Nifty and Sensex. Let’s get started.
How to Calculate Nifty?
The Nifty calculation occurs according to the free-float market capitalization-weighted methodology. It presents the total market value or price of the 50 Nifty constituents from the day it was founded, i.e., 3 November 1995.
The companies that will be calculated must be in the Nifty top 50 companies trading actively with NSE. Moreover, Nifty 50 constitutes a 0.5% or less average impact cost for over six months for a portfolio of Rs.10 crore.
To calculate the Nifty index, obtain the market capitalization by multiplying the number of shares by their price. In simple words, use the formula:
Market Capitalization = Shares * Prices
To calculate the free-float market capitalization, multiply the Investable Weight Factor (IWF) with the market capitalization.
IWF stands for the percentage of the shares that investors can freely trade in the stock market. Simply put, this is the percentage of the shares not maintained by any company or director.
Suppose you need to calculate the index value by dividing the current market value by the base market value and multiplying by the base index value, 1000.
Below is the formula for the same:
Index Value = Current Market Value / Base Market Capital*1000
(the base market capital of Nifty is Rs.2.06 trillion)
The index value indicates the profit an investor can earn if they invest in a specific portfolio.
How to Calculate Sensex?
Sensex also follows the same method as Nifty. Like Nifty, it also presents the total market value or price of the 30 top constituents from the day it was founded, i.e.,1978-1979.
Each constituent must weigh 0.5% of the stated index. Moreover, a stock should have a trading history of at least 1 year and must have traded on every trading day, then only it will be considered a constituent.
To calculate Sensex, first, calculate each company’s market capitalization using the same formula mentioned above. Then, to calculate the free floatation capitalization, you need to multiply the derived market capitalization with a free float factor.
The free-float market capitalization of the 30 companies is divided by the index divisor of 100.
Index Value = Free Float Market Capitalisation / Index Divisor
The index divisor is the relationship between the base period and the current period. Just like Nifty, Sensex also reflects the returns you can earn by investing in the portfolio.
In the last segment, we will talk about the factors affecting the performance of an Index:
Factors Affecting Indexes
Sensex and Nifty are very touchy to the Economy. When the economy is flourishing, it gets reflected in the share market’s performance, and the indexes will be upward. A few factors that affect the performance of these indexes are:
Change In The Rate Of Interest: interest rate and share market move opposite always! When the interest rate increases, the loan becomes expensive. Therefore, the companies reduce their expenses, putting pressure on the stock market, which results in a decrease in indexes.
Inflation: rising inflation portrays a circumstance in which the value of money experiences an immense fall. When inflation is high, investors have little money to invest, and the companies will also suffer because of the rising cost in the economy and lead to a fall in the share market.
Global Economy: the global economy and politics are also responsible for the downfall of Sensex and Nifty. Recession is the best example that impacts the global economy, so the performance of indexes.
In the end, we can conclude that the Nifty and Sensex are the two major indices of the stock market in India. Both these indexes tell the strength of the share market with many similarities.
Though the difference between Sensex and Nifty is that they are designed to predict 30 and 50 companies’ performance, respectively, the base value of the index for Sensex is 100 and for the Nifty is 1000.
Sensex is the part of the older exchange which is the Bombay Stock exchange whereas Nifty is the part of the National Stock Exchange. Understanding the difference between the two gives you an idea to enter or exit the market.
