DEFINITION of 'Eighthed'

A slang term used to describe when one trader undercuts or outbids another's ask or bid by one-eighth of a dollar. This term carries a derogatory connotation, as it implies an attempt to steal a trade by a small change in price.


The term is no longer used in the equity markets, as stocks are no longer quoted to an eighth of a dollar. A trader may use the term in the context of "being eighthed" or claiming that someone topped or cut them "by an eighth."
