oversubscription(redirected from Over-Booked Issue)
A situation in which investors show so much interest in a new issue of a security that demand exceeds supply. Before a new issue, underwriters canvass potential investors, who may or may not book an order to buy a portion the new issue. If investors order more shares than there are shares being issued, the security is said to be oversubscribed. This may affect the price when the security is actually issued.
