Spreads involve the purchase of one futures contract and the sale of a different futures contract in the hope of profiting from a widening or narrowing of the price difference. Because gains and losses occur only as the result of a change in the price difference--rather than as a result of a change in the overall level of futures prices--spreads are often considered more conservative and less risky than having an outright long or short futures position. In general, this may be the case. It should be recognized, though, that the loss from a spread can be as great as--or even greater than--that which might be incurred in having an outright futures position. An adverse widening or narrowing of the spread during a particular time period may exceed the change in the overall level of futures prices, and it is possible to experience losses on both of the futures contracts involved (that is, on both legs of the spread).
