In economics and finance, arbitrage is the practice of taking advantage of a difference in prices in two or more markets; striking a combination of matching deals to capitalise on the difference, the profit being the difference between the market prices at which the unit is traded. When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit after transaction costs. For example, an arbitrage opportunity is present when there is the possibility to instantaneously buy something for a low price and sell it for a higher price.
In finance, a derivative is a contract that derives its value from the performance of an underlying entity. This underlying entity can be an asset, index, or interest rate, and is often simply called the "underlying". Derivatives can be used for a number of purposes, including insuring against price movements (hedging), increasing exposure to price movements for speculation, or getting access to otherwise hard-to-trade assets or markets.
In finance, a futures contract is a standardized legal contract to buy or sell something at a predetermined price for delivery at a specified time in the future, between parties not yet known to each other. The asset transacted is usually a commodity or financial instrument. The predetermined price of the contract is known as the forward price. The specified time in the future when delivery and payment occur is known as the delivery date. Because it derives its value from the value of the underlying asset, a futures contract is a derivative.
A credit risk is risk of default on a debt that may arise from a borrower failing to make required payments. In the first resort, the risk is that of the lender and includes lost principal and interest, disruption to cash flows, and increased collection costs. The loss may be complete or partial. In an efficient market, higher levels of credit risk will be associated with higher borrowing costs. Because of this, measures of borrowing costs such as yield spreads can be used to infer credit risk levels based on assessments by market participants.
Mark-to-market or fair value accounting is accounting for the "fair value" of an asset or liability based on the current market price, or the price for similar assets and liabilities, or based on another objectively assessed "fair" value. Fair value accounting has been a part of Generally Accepted Accounting Principles (GAAP) in the United States since the early 1990s, and is now regarded as the "gold standard" in some circles. Failure to use it is viewed as the cause of the Orange County Bankruptcy, even though its use is considered to be one of the reasons for the Enron scandal and the eventual bankruptcy of the company, as well as the closure of the accounting firm Arthur Andersen.
An exchange-traded fund (ETF) is a type of investment fund and exchange-traded product, i.e. they are traded on stock exchanges. ETFs are similar in many ways to mutual funds, except that ETFs are bought and sold from other owners throughout the day on stock exchanges whereas mutual funds are bought and sold from the issuer based on their price at day's end. An ETF holds assets such as stocks, bonds, currencies, futures contracts, and/or commodities such as gold bars, and generally operates with an arbitrage mechanism designed to keep it trading close to its net asset value, although deviations can occasionally occur. Most ETFs are index funds: that is, they hold the same securities in the same proportions as a certain stock market index or bond market index. The most popular ETFs in the U.S. replicate the S&P 500, the total market index, the NASDAQ-100 index, the price of gold, the "growth" stocks in the Russell 1000 Index, or the index of the largest technology companies. With the exception of non-transparent actively managed ETFs, in most cases, the list of stocks that each ETF owns, as well as their weightings, is posted daily on the website of the issuer. The largest ETFs have annual fees of 0.03% of the amount invested, or even lower, although specialty ETFs can have annual fees well in excess of 1% of the amount invested. These fees are paid to the ETF issuer out of dividends received from the underlying holdings or from selling assets.
Over-the-counter (OTC) or off-exchange trading or pink sheet trading is done directly between two parties, without the supervision of an exchange. It is contrasted with exchange trading, which occurs via exchanges. A stock exchange has the benefit of facilitating liquidity, providing transparency, and maintaining the current market price. In an OTC trade, the price is not necessarily publicly disclosed.
An equity swap is a financial derivative contract where a set of future cash flows are agreed to be exchanged between two counterparties at set dates in the future. The two cash flows are usually referred to as "legs" of the swap; one of these "legs" is usually pegged to a floating rate such as LIBOR. This leg is also commonly referred to as the "floating leg". The other leg of the swap is based on the performance of either a share of stock or a stock market index. This leg is commonly referred to as the "equity leg". Most equity swaps involve a floating leg vs. an equity leg, although some exist with two equity legs.
Liquidity risk is a financial risk that for a certain period of time a given financial asset, security or commodity cannot be traded quickly enough in the market without impacting the market price.
In finance, a contract for difference (CFD) is a legally binding agreement that creates, defines, and governs mutual rights and obligations between two parties, typically described as "buyer" and "seller", stipulating that the buyer will pay to the seller the difference between the current value of an asset and its value at contract time. If the closing trade price is higher than the opening price, then the seller will pay the buyer the difference, and that will be the buyer’s profit. The opposite is also true. That is, if the current asset price is lower at the exit price than the value at the contract’s opening, then the seller, rather than the buyer, will benefit from the difference.
Prime brokerage is the generic name for a bundled package of services offered by investment banks, wealth management firms, and securities dealers to hedge funds which need the ability to borrow securities and cash in order to be able to invest on a netted basis and achieve an absolute return. The prime broker provides a centralized securities clearing facility for the hedge fund so the hedge fund's collateral requirements are netted across all deals handled by the prime broker. These two features are advantageous to their clients.
In finance, margin is the collateral that a holder of a financial instrument has to deposit with a counterparty to cover some or all of the credit risk the holder poses for the counterparty. This risk can arise if the holder has done any of the following:
In finance, a collar is an option strategy that limits the range of possible positive or negative returns on an underlying to a specific range. A collar strategy is used as one of the ways to hedge against possible losses and it represents long put options financed with short call options. The collar combines the strategies of the protective put and the covered call.
Options Clearing Corporation (OCC) is a United States clearing house based in Chicago. It specializes in equity derivatives clearing, providing central counterparty (CCP) clearing and settlement services to 16 exchanges. Started by Wayne Luthringshausen and carried on by Michael Cahill. Its instruments include options, financial and commodity futures, security futures and securities lending transactions.
Concentration risk is a banking term describing the level of risk in a bank's portfolio arising from concentration to a single counterparty, sector or country.
A central clearing counterparty (CCP), also referred to as a central counterparty, is a financial institution that takes on counterparty credit risk between parties to a transaction and provides clearing and settlement services for trades in foreign exchange, securities, options, and derivative contracts. CCPs are highly regulated institutions that specialize in managing counterparty credit risk.
Collateral has been used for hundreds of years to provide security against the possibility of payment default by the opposing party in a trade. Collateral management began in the 1980s, with Bankers Trust and Salomon Brothers taking collateral against credit exposure. There were no legal standards, and most calculations were performed manually on spreadsheets. Collateralisation of derivatives exposures became widespread in the early 1990s. Standardisation began in 1994 via the first ISDA documentation.
Credit valuation adjustments (CVAs) are accounting adjustments made to reserve a portion of profits on uncollateralized financial derivatives. They are charged by a bank to a risky counterparty to compensate the bank for taking on the credit risk of the counterparty during the life of the transaction. These most common transaction types are interest rate derivatives, foreign exchange derivatives, and combinations thereof. The reserved profits can be viewed mathematically as the net present value of the credit risk embedded in the transaction.
The European Market Infrastructure Regulation (EMIR) is an EU regulation aimed at reducing systemic counterparty and operational risk and thereby prevent future financial system collapses. Its focus is regulation of over-the-counter (OTC) derivatives, central counterparties and trade repositories. It provides steer on reporting of derivative contracts, implementation of risk management standards and common rules for central counterparties and trade repositories.
An X-Value Adjustment is an umbrella term referring to a number of different “valuation adjustments” that banks must make when assessing the value of derivative contracts that they have entered into. The purpose of these is twofold: primarily to hedge for possible losses due to other parties' failures to pay amounts due on the derivative contracts; but also to determine the amount of capital required under the bank capital adequacy rules. XVA has led to the creation of specialized desks in many banking institutions to manage XVA exposures.
