How can Implied Volatility estimate potential range of movement on a stock
- Expressed as percentage of the stock
- Indicating one standard deviation move for T = 1
stock XYZ is trading at $50, and the implied volatility of an option contract is 20%. -> implies that
- consensus in the marketplace that a one standard deviation move over the next 12 months will be plus or minus:
($50 x 0.20) = $10
Percentage of one standard deviation on normal distribution
68%
Percentage of two standard deviation on normal distribution
95%
Percentage of three standard deviation on normal distribution
99%
How much percentage of the time will stock be above $60 and how much percentage of the time still stock be below $40
16% of the time above $60
16% of the time below $40

the probability that a stock will wind up at any given price at the end of a 12-month period
