Please explain how to do the question 2 (a+b). Please provide the calculation and explain why.

Calculate the P/L for the following futures trades: A short wheat futures contract sold at a contract price of exist4.00/bushel and closed out at a contract price of exist4.50/bushel. Contract size is 5,000 bushels. -exist2, 500 A short wheat futures contract sold at a contract price of exist4.00/bushel and closed out at a contract price of exist3.80/bushel.

A silver-mining company wants to hedge the risk associated with the price of silver and sells 10 futures contracts. Calculate the net cashflow for the company if the company mines and delivers 55,000 ounces of silver on the date of the expiration of the silver futures contracts if the silver spot price is exist13.50/ounce or exist16.75/ounce. The net cashflow should include the revenue from the sale of silver as well as the profit/loss on the futures contracts. Explain the difference in net cashflows across the two outcomes considered. @13.50/ounce CF = exist822, 500: @exist16.75/ounce CF = exist838, 750 A solar panel company is planning to purchase 15,000 ounces of silver as part of their production operations. The company hedges by purchasing 3 silver futures contracts. Calculate the net cashflow for the company from the direct purchase of silver as well as the silver futures contracts if the spot price at expiration is exist13.50/ounce of exist16.75/ounce. @exist13.50/ounce and @exist16.75/ounce CF = -exist26, 500 The current e-mini S&P 500 futures contract (3 months to expiration, multiplier 50) price is 2,009. Determine the appropriate position to take in the futures market to accomplish the stated goal Speculate on a decrease in the price of oil with a position size of 15,000 barrels. Current futures contracts with an expiration of 6-months have a contract price of exist40.75 and contract size of 1,000 barrels.
