Tight(redirected from a tight corner)
Also found in: Dictionary, Thesaurus, Legal, Idioms, Encyclopedia.
A market or security with high trading volume and a small bid-ask spread. However, an investor can profit in a tight market, especially if he/she trades large numbers of securities. When the bid-ask spread is narrow, an investor may have difficulty making more than a small return for each trade, but sheer numbers can make returns add to a substantial amount.
