Used to refer to the forced sale of a security by an investor because of the action of another party. For example, the writer of a call option has the underlying stock called away when the call owner exercises the option. Likewise, a bondholder may have bonds called away by the issuer if interest rates decline and the issuer decides to redeem a portion of the issue before maturity. In nearly all cases, a call works to the disadvantage of the owner of the security.
