In 1973, Fischer Black and Myron Scholes published an equation that changed finance. Its strange achievement wasn’t predicting where a stock would go. It showed that an option could be valued without knowing the future path of the stock. The model starts with things you can observe: Price. Strike. Time to expiration. Interest rate. Volatility. From those inputs, it estimates a theoretical option value. But there is a subtle lesson here. A model doesn’t need to predict the future to be useful. Sometimes its job is to translate uncertainty into a common language. That idea quietly transformed derivatives trading. Instead of asking only “What will happen?” finance gained another question “What is the market currently charging for the possibility that it happens?” Prediction asks for an answer. Pricing asks you to put a number on uncertainty. Those are very different intellectual problems. #OptionsTrading# #Trading# #Finance#
