1. The Black-Scholes Bond Price Volatility Formula
The Black-Scholes bond price volatility formula is the most widely used and recognized method for calculating the price volatility of fixed income securities. It was developed in the 1970s by Myron S. Black and Robert M. Scholes and has since been used by investors, analysts, and portfolio managers to value and manage fixed income portfolios.
The Black-Scholes formula for bond price volatility is as follows:
√ó = (√ó2√ó√ó√ó√ó)1/2
where:
√ó = Bond price
√ó = Bond face value
√ó = Term to maturity (in years)
√ó = Annual coupon rate
√ó = Current interest rate
√ó = Time to expiration (in years)
√ó = Dividend yield (if applicable)
