This article provides a guide to the Excel volatility formulas and their applications, helping users to understand and utilize this powerful tool in their financial analysis.
Excel Volatility Formulas
There are several Excel volatility formulas available, each with its own characteristics and applications. The most common formulas include:
1. Historical Volatility (HV)
The historical volatility (HV) formula calculates the historical price movement of a security or market over a specified time period. It is often used to estimate the future volatility of a security, as well as to value option contracts and make investment decisions. The HV formula is calculated using the following formula:
HV = SQRT(VAR)
where VAR is the average annual volatility of the security or market over the specified time period.
2. Future Volatility (FV)
The future volatility (FV) formula calculates the future price movement of a security or market over a specified time period. It is often used to value option contracts and make investment decisions based on expected future price movements. The FV formula is calculated using the following formula:
FV = HV * (STD/HW)^(1/2)
where HW is the high price of the security or market over the specified time period, STD is the standard deviation of the security or market over the specified time period, and HV is the historical volatility of the security or market over the specified time period.
3. Option Volatility (OV)
The option volatility (OV) formula calculates the volatility of a put or call option contract based on the volatility of the underlying security or market. It is often used to value option contracts and make investment decisions based on the volatility of the option contract. The OV formula is calculated using the following formula:
OV = SQRT(N(DSQRT(KW/HP) + (HW - KW)^2/4))
where KW is the strike price of the option contract, HP is the current price of the underlying security or market, and HW is the high price of the underlying security or market.
