You are responsible for managing the risk of a portfolio of assets whose value is sensitive to changes in the value of gold. Your portfolio is currently delta neutral. However, your portfolio currently has a gamma of -20 and a vega (per %) of -20,000.

There are put and call options written on gold. For simplicity, assume that the options are for cash settlement on the expiration date, where each contract is for $100 times the amount the value of gold is in the money relative to the exercise price at expiration; that is, each contract is like you have 100 options written on 1 share (i.e., ounce) of gold. The current value of gold is $1300 per ounce. The annual volatility of gold is currently estimated to be = .21 (i.e., 21 percent). The current annualized risk-free rate of interest is 2.0 percent at all maturities over the next year.

Below is some data on a few of the options available in the market currently. The values are per share; the values per contract are 100 times the values shown below. All values are for European call options.
