Research Project 8

RP8. Financial models, volatility risk, and variable annuities (Hanxue Yang)

Leading Partner: TUT. Supervisor: Prof. Juho Kanniainen

Before the recent financial crisis, change in the volatility of the equities market has typically not been hedged for variable annuities. Consequently, a sharp rise in volatility led to a dramatic increase in the cost of hedging variable annuities, and hedging against changes in volatility became necessary for successful operation with variable annuities, a topic considered in the present RP. This  RP takes a closer look at the hedging performance of different stochastic volatility models, incorporating Lévy jump components in both stock price and volatility processes, and the valuation and risk management strategies will be discussed using these advanced models.  This RP has clear connections with RPs 1-5 and 6, 7. Specifically, whereas RP 7 focuses on modelling and estimating volatility risk, this RP, as applied research, analyzes ways of taking the volatility risk into account in managing financial risks for variable annuities. On the computational front the researcher will collaborate with WP5 (RP 11-14).
