Lexicon - Finance
  • Equity: A stock or any other security representing an ownership interest.

  • Futures Contract: a type of derivative instrument, or financial contract, in which two parties agree to transact a set of financial instruments or physical commodities for future delivery at a particular price.

  • Fixed-income Security: An investment that provides a return in the form of fixed periodic payments and the eventual return of principal at maturity. Unlike a variable-income security, where payments change based on some underlying measure such as short-term interest rates, the payments of a fixed-income security are known in advance.

  • Security: a tradable financial asset. It is commonly used to mean any form of financial instrument, but the legal definition of a "security" varies by legal and regulatory jurisdiction.

  • Derivatives: A derivative is a security with a price that is dependent upon or derived from one or more underlying assets. The derivative itself is a contract between two or more part

Lexicon - CS
  • algebraic data type: a kind of composite type, i.e. a type formed by combining other types. Two common classes of algebraic type are:
    • product types i.e. tuples
    • records and sum types, also called tagged or disjoint unions or variant types

Algebraic" refers to the property that an Algebraic Data Type is created by "algebraic" operations. The "algebra" here is "sums" and "products":

  • "sum" is alternation (A | B, meaning A or B but not both)
  • "product" is combination (A B, meaning A and B together)
