What is Volatility?

Volatility measures how much prices move. It's the statistical dispersion of returns — how spread out the price movements are.

Measuring Volatility

Historical Volatility


Calculated from past price movements, typically using standard deviation of returns.

Implied Volatility


Derived from options prices, reflecting the market's expectation of future volatility.

ATR (Average True Range)


The average range between high and low prices over a period, commonly used by traders.

Volatility Regimes

Markets cycle through volatility regimes:

Low Volatility: Small daily moves, tight ranges, trending markets often precede increased volatility.

High Volatility: Large daily swings, wide ranges, often occurs during fear/uncertainty.

Trading Implications

Position Sizing


Increase size in low volatility, decrease in high volatility to maintain consistent risk.

Strategy Selection


Some strategies work better in different regimes — trend following often struggles in low volatility while mean reversion may struggle in high volatility.

Stop Placement


Wider stops in volatile markets, tighter in calm markets.

Volatility as Opportunity

Many traders specifically seek volatility:

  • Options traders trade volatility itself

  • Day traders need movement to profit

  • Mean reversion strategies like Delorean's often find opportunities during volatility expansions
  • Sources:

  • Nassim Taleb, volatility research

  • CBOE VIX documentation
  • Risk Disclosure: Trading involves substantial risk of loss. Past performance is not indicative of future results. Only trade with capital you can afford to lose.

    Frequently Asked Questions

    What is volatility in trading?

    Volatility measures how much prices move over a given period. High volatility means large price swings (up or down), while low volatility means prices stay relatively stable. Volatility is typically measured using standard deviation of returns or indicators like ATR.

    What is the VIX?

    The VIX (Volatility Index) measures expected volatility in the S&P 500 over the next 30 days, derived from options prices. Often called the 'fear index,' the VIX rises when markets are stressed and falls during calm periods. A VIX above 30 indicates high fear; below 15 suggests complacency.
