Again, suppose silver is currently selling at $4.23 per ounce in the spot market. Assume as well that the current risk-free rate (implied repo rate) is 3.75% and that silver contracts involve 5000 ounces each. Also, now assume that carrying costs (storage and insurance) for silver are accessed at .31% (0.0031) per ounce price.

b. If the 6 month (180 day) futures contract for silver is selling for $4.18 per ounce, what should you, as an investor, do?
