Quantify and understand the exact sources of pricing uncertainty.
Computed prices for exotic derivatives often come with some degree of uncertainty.
In order to quantify price uncertainty, LexiFi Price Uncertainty tool provides a confidence interval for a given price. The certainty level is measured by a volatility indicator that we define as the Confidence Interval Equivalent Volatility (CIEV).
Let us suppose you compute the price of an Autocall. Then, you calculate its uncertainty score with LexiFi Apropos methodology; here is a summary of the output result:
Figure 1: Results of the price uncertainty estimation for an Autocall on NIKKEI 225, EURO STOXX 50 and S&P 500. The overall uncertainty is moderate.
The choice of the pricing model is a significant contributor (75%) to this price uncertainty as shown in the graph “Per Category.” Uncertainty related to the underlyings' market data represents 6.37%.
