Beta and volatility both measure risk, but they capture different aspects. Understanding each helps you build a portfolio aligned with your risk tolerance.

What Is Volatility?

Measures how much an asset's price fluctuates over time.

Usually calculated as standard deviation of returns.

Higher volatility = larger price swings in both directions.

What Is Beta?

Measures an asset's sensitivity to market movements.

Beta of 1.0 = moves with the market.

Beta > 1.0 = more volatile than market; Beta < 1.0 = less volatile.

Key Differences

Volatility is absolute; beta is relative to a benchmark.

A stock can be volatile but have low beta if its movements are uncorrelated with the market.

Beta is useful for understanding systematic risk; volatility captures total risk.

Example: Comparing Two Stocks

Stock A has volatility of 40% and beta of 0.8. Stock B has volatility of 25% and beta of 1.3.

  • 4.In a market decline: Stock B loses more
