$5.$"Consider two upcoming IPOs. The Pool Shark Inc.$\text{'}$s IPO is undersubscribed and so all bidders are allocated all the shares they ordered. In contrast, the Drop Dead Corp.$\text{'}$s IPO is oversubscribed and so the bidders receive only $43\%$ of the shares they ordered. Both IPOs are priced at $$32$ per share, but the true value per share of Drop Dead is $$42$ and the true value per share of Pool Shark is $$25.$ JB does not know the true values and, therefore, he has placed orders for $4,000$ shares in each of these two IPOs. Find JB$\text{'}$s first$-$day percentage return assuming the prices on the first day of trading are equal to the firms' true values."
