The purchase or sale of securities in quantities of fewer than the standard trading lot - 100 shares of stock or $1,000 worth of bonds - is considered an odd lot.
At one time, trading an odd lot might have cost you a slightly higher commission, but in the electronic trading environment that's generally no longer the case.
