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
