Smile Interpolation and Extrapolation
In this paper, we review techniques for smile interpolation and extrapolation, and compare numerical results across the different methodologies. Examples of smile interpolation include spline interpolations, mixed lognormal model and SABR model together with various volatility approximation formulas. For smile extrapolation, we introduce two methods: shifted lognormal model and elementary-function-based approach.
An Introduction to Caplet Stripping
This paper is neither a primer on vanilla interest rate derivatives or numerical optimisation. It is, as its name suggests, an introduction to caplet stripping, i.e. inferring caplet/floorlet prices from the market prices of interest rate caps and floors. This of course required some numerical optimisation. We present several techniques (of different levels of sophistication) to achieve our goal.
