Learn about Market Capitalization, its significance, and how it is used to classify companies based on their size and stability.

Market cap is commonly used to classify companies as large, medium, or small, and is a useful metric for investors looking to compare companies within a particular industry.

Understanding Market Capitalization

Formula

The formula for calculating market capitalization is:

Market Capitalization=Current Share Price×Total Number of Outstanding Shares \text{Market Capitalization} = \text{Current Share Price} \times \text{Total Number of Outstanding Shares}

Significance

  • Company Size Classification: Market capitalization categorizes companies into different tiers such as large-cap, mid-cap, and small-cap, reflecting their size and stability.
  • Investor Perception: It offers investors a quick way to gauge a company's size and the potential risk and reward associated with its stock.

Categories Based on Market Capitalization

  • Large-Cap: Companies valued over ₹20,000 crores, perceived as stable and safe investments.
  • Mid-Cap: Companies with market caps between ₹5,000 crores and ₹20,000 crores, known for their growth potential and moderate risk.
  • Small-Cap: Companies valued below ₹5,000 crores, seen as the most volatile with potential for significant growth.

Example: Infosys

Assuming Infosys has a current share price of ₹1,500 and there are 2 billion outstanding shares, its market capitalization would be:

₹1,500×2,000,000,000=₹3 trillion \text{₹1,500} \times 2,000,000,000 = \text{₹3 trillion}

This positions Infosys as a large-cap company, indicating its substantial size and market value.
