| 研究実績の概要 |
We investigates the daily share prices of Japan NIKKEI 225 Stock Market Indexes and the Dow-Jones industrial average for long term observations and identifies pure jumps using a Merton model, which consists of the Black-Scholes model and a compound Poisson process with a stochastic volatility. The financial data is observed in the 30 years period from 25/May/1985 to 2/May/2015. Furthermore, a robustness of the scheme with respect to selecting observation periods is also shown to investigate three periods of each 10 years in the 30 years. To resolve the above problem we focus on that the number of big jumps of returns of stock indexes which follows Poisson distribution since such returns are generated from the compound Poisson part of the Merton model.
