Volatility

A measure of how much an asset's price fluctuates over time. Higher volatility means larger price swings.

What is Volatility?

Volatility measures the degree of price variation over time. In crypto, it's typically expressed as a percentage showing how much the price deviates from its average.

Bitcoin's volatility is famously high compared to traditional assets, which creates both opportunity and risk.

Types of Volatility

Historical Volatility (HV)

Calculated from past price data. Shows how volatile an asset has been.

Implied Volatility (IV)

Derived from options prices. Shows expected future volatility.

Realized Volatility

Actual volatility that occurred over a specific period.

Measuring Volatility

Standard Deviation: Most common measure

  • Low: Under 2% daily moves
  • Medium: 2-5% daily moves
  • High: 5%+ daily moves

Bitcoin Average: ~3-4% daily volatility (vs ~1% for S&P 500)

Why It Matters

  1. Risk Assessment: Higher volatility = higher risk
  2. Position Sizing: Adjust size based on volatility
  3. Options Pricing: IV directly affects option premiums
  4. Stop-Loss Placement: Wider stops needed in volatile markets

Volatility Patterns

  • Volatility Clustering: High vol tends to follow high vol
  • Mean Reversion: Extreme volatility returns to average
  • Weekends/Holidays: Often lower volatility
  • News Events: Spike volatility around announcements

Trading Volatility

  • High Vol: Reduce position size, widen stops
  • Low Vol: Breakouts may be coming, prepare for expansion
  • Vol Crush: After events, IV drops rapidly (affects options)
