What is market cap or market capitalisation?

Also known as market cap or m cap, market capitalisation is one of the ways to calculate the value of a listed company. It represents the total value of a company based on the current market value of its stocks.

How to calculate market capitalisation?

Now that you know what is market cap, the following is the formula to calculate the m cap of a company,

MC = N x P


MC is for market capitalisation

N is the number of outstanding shares

P is the current market price per share

Let’s calculate the market cap for XYZ Co. It has 10 lakh shares of market value Rs 10 per share. As such, the m cap of XYZ Co. is Rs 100 lakh.

You can also use the market cap method of valuation to value a stock exchange. As per Wikipedia, NSE had a total market capitalisation of over $2.27 lakh cr as of Apr 2018.

What is free-float market capitalisation?

The market cap of listed companies considers the total outstanding equity shares—the total number of shares—issued by a company. These include shares held by the promoters, management, employees of the company, institutional investors, and the public. Of these, the equity held by investors other than the public is called ‘restricted shares’, which can’t be traded by the public.

On the other hand, the shares held by the public are called free-float stocks because these can be traded on the bourses without restrictions. Depending on the shares available for the public, a company can have low or high free-float stocks. We suggest you read more on free-float stocks and its impact on your investments before proceeding.

So, the point we driving home is that market cap considers the total equity of a company, irrespective of who holds it. This means you can’t ascertain how liquid a stock is. To overcome this shortcoming of the market cap method of valuing a company, a called free-float market cap was introduced. This method considers only the free-float stock of a company however excludes shares owned by the entity’s executives.

Categories of market capitalisation

There are three types of market cap:

  • Largecap
  • Midcap
  • Smallcap

Categories of companies based on market cap

Based on the market capitalisation of an entity, listed companies in India are broadly classified into 3 categories. The stocks issued by such companies are also categorised accordingly.

Smallcap companies

These are relatively newer or younger companies that may have recently been listed on the stock market. Since these are fairly new in their industry and the market, smallcap companies are risky and have lesser financial resources and smaller balance sheets. These features make them highly volatile and relatively more vulnerable to economic turmoil.

Fortunately, their newness gives smallcap companies a bigger room for growth, which is why they have the potential to become more profitable with time. But if they fail, they would do so equally badly.

Stocks issued by smallcap companies are called smallcap stocks.

Midcap companies

These listed companies are matured when compared to smallcap businesses and so have relatively lesser potential to grow. However, midcap companies are more stable than smallcap businesses, which makes them less risky. But this is not true in all cases.

Some midcap businesses face the challenge of beating competition from largecap companies in order to survive. Moreover, some midcap companies may have formerly been largecap businesses that couldn’t weather economic conditions and lost to their competitors. Yet others may be operating in a smaller niche and have little growth prospects.

Stocks issued by midcap companies are called midcap stocks.

Largecap companies

Among all three categories, largecap companies are the most matured, which leaves relatively the least scope for growth. As such, the returns of these businesses are also lower than the midcap and smallcap companies. Typically, largecap companies are market leaders because they may have overcome tough economic and market conditions and emerged stronger. These features also make largecap companies less risky and the most stable of all.

Largecap companies have larger balance sheets and ample financial resources, which make them better positioned to survive an economic downturn. Generally, largecap companies generate more cash than what’s necessary for their business and so distribute it as a dividend to investors. That’s why you can find the best dividend stocks in largecap companies.

Stocks issued by largecap companies are called largecap stocks.

Which stocks should you have in your investment portfolio?

After familiarising yourself with the types and features of listed companies based on market cap, you may be wondering stocks of which category(ies) you should include in your investment portfolio. Well, the answer is to have a diversify your portfolio. Doing this would help minimise the risk.

When doing so, invest in a combination of smallcap, midcap, and largecap stocks based on these factors:

  • Goals
  • Risk appetite
  • Return expectation

For instance, if you are looking to invest for retirement, you can consider investing a larger portion of your portfolio in largecap stocks as they are stable. On the other hand, if you can stomach high risk and are looking to create wealth over years, you can consider allocating the majority of funds in smallcap and midcap stocks.

Using Tickertape to pick stocks based on market capitalisation

To pick stocks based on the market cap, head to and filter stocks by either selecting largecap, midcap, smallcap options under “Market Cap” section. Alternatively, you can also set the numeric limit to the m cap by manually punching in your desired figures or moving the toggle bar.

Shortcomings of market cap as a method to evaluate a company

Though the market cap of a company indicates the risk associated with its stock and potential returns it can generate, this method is not versatile. This is mainly because the market capitalisation is influenced by various factors:

  • Demand for a company’s products and the ability to meet it
  • Fluctuations in the market
  • Reputation and reliability of a company
  • Change in the stock prices
  • Exercising the warrant on stocks
  • Performance of competitors
  • Change in the number of outstanding shares due to buyback of shares, issuance of new and bonus shares

Alternative to value a company: Enterprise value

Since market cap only considers the equity value of a company, the method doesn’t show a fair picture of the entity. Ergo, some investors use the ‘Enterprise value’ to evaluate an entity. This method not only considers the market cap of a company but also its short- and long-term debts, which shows a truer picture of an entity. Here’s the formula.

EV = MP + D – C


Enterprise value = EV

Market cap = MP

D = Short- and long-term debt

C = cash and cash equivalents, liquid assets of a company but not marketable securities​

Now that you know what is market capitalisation and how listed companies are classified based on the same, it is time to do your homework and plan your investments smartly. Most financial advisors swear by one rule of investment–diversification. It is recommended that you don’t park all your funds in:

  • Large-cap stocks to dodge risks
  • Midcap stocks to be average returns
  • Smallcap to earn high returns at the cost of high risk

Instead, analyse your risk appetite, return expectation, and goals before investing in stock(s) of largecap, midcap, and smallcap companies. As mentioned before, diversifying your investments is the best way to optimise your returns. A tip is to use Tickertape’s stock screener to pick stocks smartly.
