Decoupling

A situation in which returns on two assets or asset classes that normally move together move separately. For example, oil and natural gas prices usually move together: when one goes up, so does the other, and vice versa. Likewise, stocks and corporate bonds usually behave the same way. Decoupling in both cases occurs when oil moves in one direction while natural gas moves in the opposite, or when stocks' and corporate bonds' returns diverge.
