Louis BachelierLouis Jean-Baptiste Alphonse Bachelier (baʃəlje; 11 March 1870 – 28 April 1946) was a French mathematician at the turn of the 20th century. He is credited with being the first person to model the stochastic process now called Brownian motion, as part of his doctoral thesis The Theory of Speculation (Théorie de la spéculation, defended in 1900). Bachelier's doctoral thesis, which introduced the first mathematical model of Brownian motion and its use for valuing stock options, was the first paper to use advanced mathematics in the study of finance.
Alternative investmentAn alternative investment, also known as an alternative asset or alternative investment fund (AIF), is an investment in any asset class excluding stocks, bonds, and cash. The term is a relatively loose one and includes tangible assets such as precious metals, collectibles (art, wine, antiques, vintage cars, coins, musical instruments, or stamps) and some financial assets such as real estate, commodities, private equity, distressed securities, hedge funds, exchange funds, carbon credits, venture capital, film production, financial derivatives, cryptocurrencies, non-fungible tokens, and Tax Receivable Agreements.
Quantitative behavioral financeQuantitative behavioral finance is a new discipline that uses mathematical and statistical methodology to understand behavioral biases in conjunction with valuation. The research can be grouped into the following areas: Empirical studies that demonstrate significant deviations from classical theories. Modeling using the concepts of behavioral effects together with the non-classical assumption of the finiteness of assets. Forecasting based on these methods. Studies of experimental asset markets and use of models to forecast experiments.
Single-stock futuresIn finance, a single-stock future (SSF) is a type of futures contract between two parties to exchange a specified number of stocks in a company for a price agreed today (the futures price or the strike price) with delivery occurring at a specified future date, the delivery date. The contracts can be later traded on a futures exchange. The party agreeing to take delivery of the underlying stock in the future, the "buyer" of the contract, is said to be "long", and the party agreeing to deliver the stock in the future, the "seller" of the contract, is said to be "short".
StockbrokerA stockbroker is an individual or company that buys and sells stocks and other investments for a financial market participant in return for a commission, markup, or fee. In most countries they are regulated as a broker or broker-dealer and may need to hold a relevant license and may be a member of a stock exchange. They generally act as a financial advisor and investment manager. In this case they may also be licensed as a financial adviser such as a registered investment adviser (in the United States).
Index (economics)In statistics, economics, and finance, an index is a statistical measure of change in a representative group of individual data points. These data may be derived from any number of sources, including company performance, prices, productivity, and employment. Economic indices track economic health from different perspectives. Examples include the consumer price index, which measures changes in retail prices paid by consumers, and the cost-of-living index (COLI), which measures the relative cost of living over time.
T-modelIn finance, the T-model is a formula that states the returns earned by holders of a company's stock in terms of accounting variables obtainable from its financial statements. The T-model connects fundamentals with investment return, allowing an analyst to make projections of financial performance and turn those projections into a required return that can be used in investment selection.
Model riskIn finance, model risk is the risk of loss resulting from using insufficiently accurate models to make decisions, originally and frequently in the context of valuing financial securities. However, model risk is more and more prevalent in activities other than financial securities valuation, such as assigning consumer credit scores, real-time probability prediction of fraudulent credit card transactions, and computing the probability of air flight passenger being a terrorist.
Forward rate agreementIn finance, a forward rate agreement (FRA) is an interest rate derivative (IRD). In particular it is a linear IRD with strong associations with interest rate swaps (IRSs). A forward rate agreement's (FRA's) effective description is a cash for difference derivative contract, between two parties, benchmarked against an interest rate index. That index is commonly an interbank offered rate (-IBOR) of specific tenor in different currencies, for example LIBOR in USD, GBP, EURIBOR in EUR or STIBOR in SEK.
Two-moment decision modelIn decision theory, economics, and finance, a two-moment decision model is a model that describes or prescribes the process of making decisions in a context in which the decision-maker is faced with random variables whose realizations cannot be known in advance, and in which choices are made based on knowledge of two moments of those random variables. The two moments are almost always the mean—that is, the expected value, which is the first moment about zero—and the variance, which is the second moment about the mean (or the standard deviation, which is the square root of the variance).
