Note(s): Panel A provides parameters for Eqs. (24) and (26) to simulate the daily returns of the market index, which are taken from Table 1 of Neuberger (2012). Here, denotes the mean of , which follows an exponential distribution; and denote the mean and standard deviation of , which follows a normal distribution; is the correlation between and ; and is the jump intensity of the Poisson process . In addition, we set to ensure that is a martingale under both P and Q measures. Panel B provides parameters for Eqs. (25) and (27) to simulate the daily returns of two individual stocks among 29 stocks listed in Tables 6 and 7 of Gourier (2016). Some parameters in Panel B are modified from the original source. For example, = 0.023 in the first row is obtained from = 5.9 in Gourier (2016) by dividing it by 252 to simulate daily return processes. In addition, while Gourier (2016) assumes that jump intensity is an affine function of the instantaneous variance process, our model assumes a constant jump intensity. Accordingly, we set (%), where and are the intercept and slope parameters, respectively, in Gourier (2016). Finally, we set to ensure is a martingale under both P- and Q-measures
