Definition of Volatility

Volatility refers to the degree of variation in the price of a financial asset, such as stocks, bonds, or commodities, over time. It is often measured using standard deviation or beta and indicates how frequently and sharply prices fluctuate.

A high-volatility asset experiences significant price swings, while a low-volatility asset moves more steadily.

For example, a technology stock may have high volatility, experiencing sharp increases and decreases, while a government bond typically exhibits lower volatility due to its stability.

Causes of Volatility

Several factors contribute to market and asset volatility, including:

• Economic Events – Inflation rates, interest rate changes, and GDP growth impact price movements.
• Market Sentiment – Investor confidence and speculation drive price swings.
• Political and Global Events – Elections, policy changes, and international conflicts create uncertainty.
• Corporate Performance – Earnings reports, leadership changes, and mergers influence stock prices.
• Supply and Demand – Changes in supply chains or demand fluctuations affect commodity and stock prices.

How Volatility Is Measured

Standard Deviation

Standard deviation measures the dispersion of asset prices from their average over a period. A higher value indicates greater price fluctuations.

Beta

Beta compares an asset's volatility to the broader market. A beta above 1 means higher-than-market fluctuations, while a beta below 1 suggests lower risk.

VIX (Volatility Index)

The VIX, or "fear index," measures expected volatility in the stock market. A rising VIX suggests increasing uncertainty.

Example: A stock with a beta of 1.5 is 50 percent more volatile than the market, meaning it experiences larger price swings.

Types of Volatility

Measures past price fluctuations over a set period to analyze trends.

Implied Volatility

Reflects future price expectations based on options market data.

Market Volatility

Represents broad market fluctuations influenced by economic and geopolitical events.

Asset-Specific Volatility

Refers to price movements in a particular stock, bond, or commodity.
