Fundamental analysis is the process of evaluating a company’s financial health, profitability, growth potential, competitive strength, and valuation using financial statements and market indicators.

The main objective is to determine:

• Whether the stock is undervalued or overvalued
• Whether the business has strong long-term growth potential
• Whether the company can survive economic downturns
• Whether investing in the company is suitable for wealth creation

Type	Approximate Size	Risk Level
Large Cap	Above ₹20,000 Cr	Lower Risk
Mid Cap	₹5,000–20,000 Cr	Moderate Risk
Small Cap	Below ₹5,000 Cr	Higher Risk

Interpretation

• Large-cap companies are usually stable and financially strong.

For long-term beginners, a portfolio with quality large-cap and selected mid-cap stocks is generally safer.
