BS() is the Black-Scholes formula for pricing a call option. In other words, ˙(K;T) is the volatility that, when substituted into the Black-Scholes formula, gives the market price, C(S;K;T). Because the Black-Scholes formula is continuous and increasing in ˙, there will always4 be a unique solution, ˙(K;T). If the Black-Scholes

Black-Scholes Equations 1 The Black-Scholes Model Up to now, we only consider hedgings that are done upfront. For example, if we write a naked call (see Example 5.2), we are exposed to unlimited risk if the stock price rises steeply. We can hedge it by buying a share of the underlying asset. This is done at the initial time when the call is sold.
