/ˈoʊvər ði ˈkaʊntər ˌdɛrɪvətɪvz/ – Noun
Definition: Các hợp đồng tài chính ngoại trực.
A more thorough explanation: privately negotiated derivatives (=a financial instrument whose price depends on the value of the shares, bonds, raw materials etc that it relates to) that are traded directly between two parties, without going through an exchange or other intermediary
Example: Reporting of OTC amounts are difficult because trades often occur in private, without activity being visible on any exchange.
