Trading costs(redirected from Trading Cost)
All commissions and other expenses related to the trade of a security. When an investor buys or sells a security, he/she must usually pay a fee to his/her investment adviser and/or broker. Research and other indirect costs informing investment decisions are not usually considered trading costs unless they directly relate to or result from a specific transaction. The investor accounts for these expenses when calculating whether an investment earned a profit or loss. See also: All in cost.
