Tiivistelmä: | The authors propose new tests to examine whether stock index futures affect stock market volatility. These tests decompose spot portfolio volatility into the cross-sectional dispersion and the average volatility of returns on the portfolio's constitent securities. The authors' tests show that for Nikkei stocks spot portfolio volatility increased and cross-sectional dispersion compared with average volatility when Nikkei futures began trading on the Osaka Securities Exchange. |
