👉 A "equerry" is a type of financial instrument that is designed to provide investors with the ability to buy and sell securities at a predetermined price, without having to wait for an established market to develop. Equities are often used as part of a portfolio or in a structured investment vehicle, such as a mutual fund or exchange-traded fund (ETF). They can be bought and sold on exchanges, which allows investors to trade their equities directly with the company they invest in.
