That move is where the arbitrageur makes money. The opposite works as well. An arbitrageur may short an overpriced call, taking a bearish stance, but at the same time offsets the risk of a bull move by entering an offsetting position on the other side of the market.

Arbitrageurs do this by constantly searching for commodities that are overvalued or undervalued. Then they pounce! Their market activity bids up the prices that are too low and pushes down those that have become too high.
