FAQ
- How is volatility calculated?
- Take daily closes, compute log returns, then multiply their standard deviation by √365. Most services use this for a market that trades every day.
- Is high volatility bad?
- It measures the size of moves in both directions, not the direction of price. Not investment advice.
