One use for futures markets is "price discovery," i.e., futures price mirrors current consensus of future price of commodity. Current price of gold is $ 950 but you expect price to rise to $ 1,000. If futures price were given as $ 990, what would you do? If expectation is fulfilled, determine profit? If futures price were $ 1,018, what would you perform? Find what futures price cause to take no action? Explain why?
