Use the Deriva Gem Application Builder functions to reproduce Table 15.2. (In Table 15.2 the stock position is rounded to the nearest 100 shares.) Calculate the gamma and theta of the position each week. Calculate the change in the value of the portfolio each week and check whether equation (15.6) is approximately satisfied. (Note: Deriva Gem produces a value of theta "per calendar day". The theta in equation (15.6) is "per year".)
