Seasonal Variance among Light Sweet Crude and Corn Futures Caleb Seeley 3/16/08
Introduction Examine Light Sweet Crude futures prices at 5 minute intervals over 20 years (1987-2007) Examine Corn futures prices at 5 minute intervals over 25 years (1982-2007) Begin by looking for significant jumps and then continue by examining variance monthly and weekly Using Bardorff-Nielson and Shephard model of jump testing.
Background Mathematics Realized Variation: Realized Bi-Power Variation:
Background Mathematics Part 2 The relative jump is defined: RJt = (RVt – BVt) / RVt In order to studentize the RJt one needs to estimate the integrated quarticity
Background Mathematics Part 3 Tri-Power Quarticity Z-statistic – used .999 significance level (3.09)
