Beta (finance)

In finance, the beta (β or market beta or beta coefficient) is a statistic that measures the expected increase or decrease of an individual stock price in proportion to movements of the stock market as a whole. Beta can be used to indicate the contribution of an individual asset to the market risk of a portfolio when it is added in small quantity. It refers to an asset's non-diversifiabl

Finance

Call option

In finance, a call option (often simply a "call") is an option contract that gives its buyer the right, but not the obligation, to buy an agreed quantity of a particular commodity, security, or other financial instrument from the seller at a specified price. The asset or instrument to which the option relates is known as the underlying, and the specified purchase price is known as the st

Capital asset pricing model

In finance, the capital asset pricing model (CAPM) is a model used to determine a theoretically appropriate required rate of return of an asset, to make decisions about adding assets to a well-diversified portfolio. The model takes into account the asset's sensitivity to non-diversifiable risk (also known as systematic risk or market risk), often represented by the quantity beta (β) in t

Fiat currencies

Debasement

A debasement of coinage is the practice of lowering the intrinsic value of coins, especially when used in connection with commodity money, such as gold or silver coins, while continuing to circulate them at face value. A coin is said to be debased if the quantity of gold, silver, copper or nickel in the coin is reduced.

In monetary economics, the equation of exchange is the relation:

Fiscal theory of the price level

The fiscal theory of the price level is the idea that government fiscal policy, including debt and taxes present and future, is the primary determinant of the price level or inflation as opposed to the quantity theory of money. The theory is one of the strongest advocates in the debate among mainstream economists for combatting inflation primarily through fiscal policy instead of monetar

Gold standard

A gold standard is a monetary system in which the standard economic unit of account is defined by a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971, when the United States unilaterally terminated convertibility of the US dollar into gold, effect

Finance

Implicit contract theory

In economics, implicit contracts refer to voluntary and self-enforcing long term agreements made between two parties regarding the future exchange of goods or services. Implicit contracts theory was first developed to explain why there are quantity adjustments (layoffs) instead of price adjustments (falling wages) in the labor market during recessions.

Finance

Margin at risk

The Margin-at-Risk (MaR) is a quantity used to manage short-term liquidity risks due to variation of margin requirements, i.e. it is a financial risk occurring when trading commodities. It is similar to the Value-at-Risk (VaR), but instead of simulating EBIT it returns a quantile of the (expected) cash flow distribution.

Finance

Market depth

In finance, market depth is a real-time list displaying the quantity to be sold versus unit price. The list is organized by price level and is reflective of real-time market activity. Mathematically, it is the size of an order needed to move the market price by a given amount. If the market is deep, a large order is needed to change the price.

Finance

Market microstructure

Market microstructure is a branch of finance concerned with the details of how exchange occurs in markets. While the theory of market microstructure applies to the exchange of real or financial assets, more evidence is available on the microstructure in the financial field due to the availability of transactions data from them. The major thrust of market microstructure research examines

Monetae cudendae ratio

"Monetae cudendae ratio" (also spelled "Monetæ cudendæ ratio"; English: "On the Minting of Coin" or "On the Striking of Coin"; sometimes, "Treatise on Money") is a paper on coinage by Nicolaus Copernicus (Polish: Mikołaj Kopernik). It was written in 1526 at the request of Sigismund I the Old, King of Poland, and presented to the Prussian Diet.

Monetary-disequilibrium theory

Monetary disequilibrium theory is a product of the monetarist school and is mainly represented in the works of Leland Yeager and Austrian macroeconomics. The basic concepts of monetary equilibrium and disequilibrium were, however, defined in terms of an individual's demand for cash balance by Mises (1912) in his Theory of Money and Credit.

Finance

Odd lotter

An odd lotter is an investor who purchases shares or other securities in small or unusual quantities. Stocks are typically traded in increments of 100 shares, a quantity known as a round lot or board lot. The cost of 100 shares of a security may be beyond the means of an individual investor, or may represent a larger investment than the investor wishes to make. Thus, the investor purcha

Finance

Option (finance)

In finance, an option is a contract which conveys to its owner, the holder, the right, but not the obligation, to buy or sell a specific quantity of an underlying asset or instrument at a specified strike price on or before a specified date, depending on the style of the option.

Proof of stake

Proof-of-stake (PoS) protocols are a class of consensus mechanisms for blockchains that work by selecting validators in proportion to their quantity of holdings in the associated cryptocurrency. This is done to avoid the computational cost of proof-of-work (PoW) schemes. The first functioning use of PoS for cryptocurrency was Peercoin in 2012, although its scheme, on the surface, still r

Quantity theory of money

The quantity theory of money (QTM) is a hypothesis within monetary economics which states that the general price level of goods and services is directly proportional to the amount of money in circulation (i.e., the money supply), and that the causality runs from money to prices. This implies that the theory potentially explains inflation. It originated in the 16th century and has been pr

Trading basics

Real bills doctrine

The real bills doctrine says that as long as bankers lend to businessmen only against the security (collateral) of short-term 30-, 60-, or 90-day commercial paper representing claims to real goods in the process of production, the loans will be just sufficient to finance the production of goods. The doctrine seeks to have real output determine its own means of purchase without affecting

Volume risk

Volume risk, also known as quantity risk, is the risk of production or sales volumes materially and adversely deviating from their expected quantities. The term has context-specific applications.
