The performance of Stock Market Indices shows how the entire market behaves. The indicators provide market movement directions while showing investor mood through their market movements. The Nifty 50 Today and Sensex serve as the primary indices which people monitor throughout India.
What Are Stock Market Indices?
A stock market index is a collection of chosen stocks which represent a specific market segment. The selection process requires stock selection based on three criteria including company size and liquidity and sector coverage.
The National Stock Exchange and the Bombay Stock Exchange operate as the institutions which control market indices throughout India.
For example:
Nifty 50 includes 50 companies listed on the NSE
Sensex includes 30 companies listed on the BSE
ow Are Indices Calculated?
In India, Stock Market Indices are calculated using the free-float market capitalization method. The method calculates the market value of shares which can be sold by investors.
Simple Formula:
Free-Float Market Cap = Share Price Ă— Total Shares Ă— Free-Float Factor
Share Price: Current market price
Total Shares: Number of shares issued
Free-Float Factor: Portion available for trading
Step-by-Step Process
1. Selecting Stocks
The process of stock selection involves choosing stocks based on their trading volume and market capitalization and liquidity. This process guarantees that the index represents the actual market conditions.
2. Assigning Weight
The index assigns weight to stocks according to their market value which is based on their floatable market capitalisation. Larger companies have greater influence over index performance.
3. Setting a Base Value
Every index has a base year and base value.
Nifty 50 uses 1000 as its base value.
4. Calculating Index Value
Index Value = (Current Market Cap / Base Market Cap) Ă— Base Value
The base year data shows the market growth status since that time.
What Happens During Corporate Actions?
Corporate actions lead to stock price movements which require index adjustments for maintaining accurate measurements.
Examples:
Stock Split: The number of shares grows while the share price decreases
Bonus Issue: Shareholders receive additional shares at no cost
Mergers: Two businesses merge into one
The index undergoes necessary adjustments to maintain its actual value during those events.
