  • Why are these companies valued at highest market capitalisation? – Detailed company analysis

There are more than 5,400 listed companies on the Bombay Stock Exchange (BSE). Around  2,000 companies are listed on the National Stock Exchange (NSE). Out of these companies only a handful companies enjoy the status of being the top companies in India. Knowing such companies in general is helpful in making good investment decisions. Therefore, here’s a list of top 10 companies with highest market capitalisation in India.

Now before I reveal the list of top 10 companies in India with highest market capitalisation, let us first understand what is market capitalisation. 

What is Market Capitalisation? – Decoding Market Capitalisation

Market capitalisation is simply the total value of issued share of a particular company. These shares are issued by the company and currently held by retail investors, institutional investors and promoters. 

Market capitalisation is also known as market cap. It essentially helps us understand the size of a company and assess its true value. 

Market Capitalisation Formula 

Market Capitalisation = Current market price (CMP) of a stock X Total number of issued share 

To calculate market capitalisation, you simply have to multiply a company’s current market price with total number of issued shares. 

Let us take a simple example and calculate market capitalisation.

Suppose the current market price of a company is Rs 500. The total number of shares issued by the company are 10 crores. So, the market capitalisation of the company will be Rs 5,000 crores (Rs 500*10 crores).  

Let us now learn how market capitalisation helps in assessing the value of a company.

1. Market capitalisation negates the noise:

 Which company is bigger?  – A company with 1 crore issued shares and a market price of Rs 10,000? Or a company with 100 crore issued shares but a market price of Rs 100? 

It may seem that the first company is the bigger one. But after calculating the market capitalisation, you will realise that both the companies are same in stature.  This is why, it is important to factor in market capitalisation while analysing stocks. 

2. Market Capitalisation aids Diversification 

Market capitalisation helps you bifurcate between large, mid and small cap companies. This is the first step in diversifying your investment portfolio. Similarly, market capitalisation also helps you invest according to your risk appetite. Companies are typically divided on the basis on market capitalization as:

  • Large-cap companies 
  • Mid-cap companies 
  • Small-cap companies 

A large-cap company has a market capitalisation of more than Rs 20,000 crores The market capitalisation of a mid-cap company is between Rs 5,000 – Rs 20,000 crores. Small-cap companies have market capitalisation of less than Rs 5,000 crores. 

Generally, large-cap stocks are considered to be less risky than mid-cap or small-cap stocks. A company with small or medium market capitalisation tends to be younger and serves niche markets or new emerging industries. Hence, these companies are considered higher risk investments rather than a larger market capitalisation company.

3. Market Cap to Gross Domestic Product (GDP) ratio 

GDP ratio determines whether the market is overvalued or undervalued as compared to historical averages.

Market Cap to GDP ratio Formula = 

[Market Cap / Gross domestic product (GDP) ratio] * 100

Practical example

The current Indian market cap is close to Rs. 257.67 lakh crores, the country’s GDP is Rs. 135.13 lakh crores

Therefore, the market cap to GDP ratio = 

[257.67 lakh crores/ 135.13 lakh crores] *100

The market cap to GDP ratio would be approximately 191.42%

This would mean that the stock market are currently overvalued. Given that 191% of GDP represents the stock market value.

With this market cap to GDP ratio, investor can create an investment strategy and try to time the markets. Smart SIP by RankMF is one of the best tools to invest as per market valuations.  In SmartSIP, experts assess the current market conditions and invest larger chunks whenever markets fall.
