Alternative trading system
Alternative trading system (ATS) is a US and Canadian regulatory term for a non-exchange trading venue that matches buyers and sellers to find counterparties for transactions. Alternative trading systems are typically regulated as broker-dealers rather than as exchanges (although an alternative trading system can apply to be regulated as a securities exchange). In general, for regulatory
Trading basicsBid–ask spread
The bid–ask spread (also bid–offer or bid/ask and buy/sell in the case of a market maker) is the difference between the prices quoted (either by a single market maker or in a limit order book) for an immediate sale (ask) and an immediate purchase (bid) for stocks, futures contracts, options, or currency pairs in some auction scenario. The size of the bid–ask spread in a security is one m
Trading basicsBlock trade
A block trade is a high-volume transaction in a security that is privately negotiated and executed outside of the open market for that security. Major broker-dealers often provide "block trading" services—sometimes known as "upstairs trading desks"—to their institutional clients. In the United States and Canada a block trade is usually at least 10,000 shares of a stock or $100,000 of bo
Securities & exchangesCross listing
Cross-listing (or multi-listing, or interlisting) of shares is when a firm lists its equity shares on one or more foreign stock exchange in addition to its domestic exchange. To be cross-listed, a company must thus comply with the requirements of all the stock exchanges in which it is listed, such as filing.
FinanceCrossing network
A crossing network is an alternative trading system (ATS) that matches buy and sell orders electronically for execution without first routing the order to an exchange or other public displayed market such as an electronic communication network (ECN). Such crossing networks are a type of dark pool that employ computerized systems to match buyers and sellers of large blocks of shares with
FinanceDirect market access
Direct market access (DMA) in financial markets is the electronic trading infrastructure that gives investors wishing to trade in financial instruments a way to interact with the order book of an exchange. Normally, trading on the order book is restricted to broker-dealers and market making firms that are members of the exchange. Using DMA, investment companies (also known as buy side fi
FinanceElectronic trading
Electronic trading, sometimes called e-trading, is the buying and selling of stocks, bonds, foreign currencies, financial derivatives, cryptocurrencies, and other financial instruments online. This is typically done using electronic trading platforms where traders can place orders and have them executed at a trading venue such as a stock market, either directly or via a broker.
FinanceFlight-to-quality
A flight-to-quality, or flight-to-safety, is a financial market phenomenon occurring when investors sell what they perceive to be higher-risk investments and purchase safer investments, such as gold and government bonds. This is considered a sign of fear in the marketplace, as investors seek less risk in exchange for lower profits.
FinanceFloor trader
A floor trader is a member of a stock or commodities exchange who trades on the floor of that exchange for their own account. The floor trader must abide by trading rules similar to those of the exchange specialists who trade on behalf of others. The term should not be confused with floor broker.
FinanceJensen's alpha
In finance, Jensen's alpha (or Jensen's Performance Index, ex-post alpha) is used to determine the abnormal return of a security or portfolio of securities over the theoretical expected return. It is a version of the standard alpha based on a theoretical performance instead of a market index.
Securities & exchangesListing (finance)
In corporate finance, a listing refers to the company's shares being on the list (or board) of stock that are publicly listed. Some stock exchanges allow shares of a foreign company to be listed and may allow dual listing, subject to conditions.
FinanceMarket anomaly
A market anomaly in a financial market is predictability that seems to be inconsistent with (typically risk-based) theories of asset prices. Standard theories include the capital asset pricing model and the Fama-French Three Factor Model, but a lack of agreement among academics about the proper theory leads many to refer to anomalies without a reference to a benchmark theory (Daniel and
FinanceMarket 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.
FinanceOdd 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
FinanceOpen outcry
Open outcry is a method of communication between professionals on a stock exchange or futures exchange, typically on a trading floor. It involves shouting and the use of hand signals to transfer information primarily about buy and sell orders. The part of the trading floor where this takes place is called a pit.
FinanceOrder book
An order book is the list of orders (manual or electronic) that a trading venue (in particular stock exchanges) uses to record the interest of buyers and sellers in a particular financial instrument. A matching engine uses the book to determine which orders can be fully or partially executed.
FinancePrimary market
The primary market is the part of the capital market that deals with the issuance and sale of securities to purchasers directly by the issuer, with the issuer being paid the proceeds. A primary market means the market for new issues of securities, as distinguished from the secondary market, where previously issued securities are bought and sold. A market is primary if the proceeds of sal
FinanceReturns-based style analysis
Returns-based style analysis (RBSA) is a statistical technique used in finance to deconstruct the returns of investment strategies using a variety of explanatory variables. The model results in a strategy's exposures to asset classes or other factors, interpreted as a measure of a fund or portfolio manager's investment style. While the model is most frequently used to show an equity mutu
FinanceSwing trading
Swing trading is a speculative trading strategy in financial markets where a tradable asset is held for one or more days in an effort to profit from price changes or swings. A swing trading position is typically held longer than a day trading position, but shorter than buy-and-hold investment strategies that can be held for months or years. Profits can be sought by either buying an asse
