Arbitrage-free implied volatility surfaces for options on single stock futures

摘要

The current method employed by the Johannesburg Stock Exchange1 (JSE) to determine implied volatility is based on trade data and a linear deterministic approach. The aim of this paper is to construct a market-related arbitrage-free implied volatility surface, by using a quadratic deterministic function, for two stock indices and ten single stock futures (SSFs). Actual traded data is used and we show practically how all no-arbitrage conditions are implemented and tested.
