Model Risk
In 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. Here, Rebonato (2002) defines model risk as "the risk of occurrence of a significant difference between the mark-to-model value of a complex and/or illiquid instrument, and the price at which the same instrument is revealed to have traded in the market". However, model risk is increasingly relevant in contexts other than financial securities valuation, including assigning consumer credit scores, real-time prediction of fraudulent credit card transactions, and computing the probability of an air flight passenger being a terrorist. In fact, Burke regards failure to use a model (instead over-relying on expert judgment) as a type of model risk.http://www.siiglobal.org/SII/WEB5/sii_files/Membership/PIFs/Risk/Model%20Risk%2024%2011%2009%20Final.pdf Types Derman describes various types of model ...

Mark To Market
Mark-to-market (MTM or M2M) 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. 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. Mark-to-market accounting can change values on the balance sheet as market conditions change. In contrast, historical cost accounting, based on the past transactions, is simpler, more stable, and easier to perform, but does not represent current market value. It summarizes past transactions instead. Mark-to-market accounting can become volat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illiquid
In business, economics or investment, market liquidity is a market's feature whereby an individual or firm can quickly purchase or sell an asset without causing a drastic change in the asset's price. Liquidity involves the trade-off between the price at which an asset can be sold, and how quickly it can be sold. In a liquid market, the trade-off is mild: one can sell quickly without having to accept a significantly lower price. In a relatively illiquid market, an asset must be discounted in order to sell quickly. A liquid asset is an asset which can be converted into cash within a relatively short period of time, or cash itself, which can be considered the most liquid asset because it can be exchanged for goods and services instantly at face value. Overview A liquid asset has some or all of the following features: it can be sold rapidly, with minimal loss of value, anytime within market hours. The essential characteristic of a liquid market is that there are always ready and wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark-to-model
Mark-to-Model refers to the practice of pricing a position or portfolio at prices determined by financial models, in contrast to allowing the market to determine the price. Often the use of models is necessary where a market for the financial product is not available, such as with complex financial instruments. One shortcoming of Mark-to-Model is that it gives an artificial illusion of liquidity, and the actual price of the product depends on the accuracy of the financial models used to estimate the price. On the other hand it is argued that Asset managers and Custodians have a real problem valuing illiquid assets in their portfolios even though many of these assets are perfectly sound and the asset manager has no intention of selling them. Assets should be valued at mark to market prices as required by the Basel rules. However mark to market prices should not be used in isolation, but rather compared to model prices to test their validity. Models should be improved to take into a ...

Financial Securities
A security is a tradable financial asset. The term commonly refers to any form of financial instrument, but its legal definition varies by jurisdiction. In some countries and languages people commonly use the term "security" to refer to any form of financial instrument, even though the underlying legal and regulatory regime may not have such a broad definition. In some jurisdictions the term specifically excludes financial instruments other than equity and fixed income instruments. In some jurisdictions it includes some instruments that are close to equities and fixed income, e.g., equity warrants. Securities may be represented by a certificate or, more typically, they may be "non-certificated", that is in electronic ( dematerialized) or "book entry only" form. Certificates may be ''bearer'', meaning they entitle the holder to rights under the security merely by holding the security, or ''registered'', meaning they entitle the holder to rights only if they appear on a security ...

Financial Model
Financial modeling is the task of building an abstract representation (a model) of a real world financial situation. This is a mathematical model designed to represent (a simplified version of) the performance of a financial asset or portfolio of a business, project, or any other investment. Typically, then, financial modeling is understood to mean an exercise in either asset pricing or corporate finance, of a quantitative nature. It is about translating a set of hypotheses about the behavior of markets or agents into numerical predictions. At the same time, "financial modeling" is a general term that means different things to different users; the reference usually relates either to accounting and corporate finance applications or to quantitative finance applications. Accounting In corporate finance and the accounting profession, ''financial modeling'' typically entails financial statement forecasting; usually the preparation of detailed company-specific models used for deci ...

Collateralized Debt Obligation
A collateralized debt obligation (CDO) is a type of structured finance, structured asset-backed security (ABS). Originally developed as instruments for the corporate debt markets, after 2002 CDOs became vehicles for refinancing Mortgage-backed security, mortgage-backed securities (MBS).Lepke, Lins and Pi card, ''Mortgage-Backed Securities'', §5:15 (Thomson West, 2014). Like other private label securities backed by assets, a CDO can be thought of as a promise to pay investors in a prescribed sequence, based on the cash flow the CDO collects from the pool of bonds or other assets it owns. Distinctively, CDO credit risk is typically assessed based on a probability of default (PD) derived from ratings on those bonds or assets. The CDO is "sliced" into sections known as tranche, "tranches", which "catch" the cash flow of interest and principal payments in sequence based on seniority. If some loans default and the cash collected by the CDO is insufficient to pay all of its investors, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaussian Copula
In probability theory and statistics, a copula is a multivariate cumulative distribution function for which the marginal probability distribution of each variable is uniform on the interval , 1 Copulas are used to describe / model the dependence (inter-correlation) between random variables. Their name, introduced by applied mathematician Abe Sklar in 1959, comes from the Latin for "link" or "tie", similar but only metaphoricly related to grammatical copulas in linguistics. Copulas have been used widely in quantitative finance to model and minimize tail risk and portfolio-optimization applications. Sklar's theorem states that any multivariate joint distribution can be written in terms of univariate marginal distribution functions and a copula which describes the dependence structure between the variables. Copulas are popular in high-dimensional statistical applications as they allow one to easily model and estimate the distribution of random vectors by estimatin ...

David X
David X ( ka, დავით X) (c. 1470s or 1480s –1526) was the second king ('' mepe'') of the Kingdom of Kartli from 1505 to 1525. Associated with the throne as a child, he became king on the death of his father and from then on had to endure invasions from the Kingdom of Imereti and Kingdom of Kakheti. A reformer, he succeeded in subduing the army and destroying the power of the nobles by abolishing the semi-independent principalities that were ruining the unity of the country, before uniting eastern Georgia under a single sceptre. David X is also known to have survived another invasion by Persia, and is thus considered to be the first in a series of eleven kings who fought against their Safavid neighbours over the next two centuries. Life David was born after 1473.. He was the eldest son of King Constantine II of Georgia and his wife, Queen Tamar. In 1488, in the midst of war against the Turkomans, he was associated with his other brothers to his father's throne, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2008 Financial Crisis
The 2008 financial crisis, also known as the global financial crisis (GFC), was a major worldwide financial crisis centered in the United States. The causes of the 2008 crisis included excessive speculation on housing values by both homeowners and financial institutions that led to the 2000s United States housing bubble, exacerbated by predatory lending for subprime mortgages and deficiencies in regulation. Cash out refinancings had fueled an increase in consumption that could no longer be sustained when home prices declined. The first phase of the crisis was the subprime mortgage crisis, which began in early 2007, as mortgage-backed securities (MBS) tied to U.S. real estate, and a vast web of Derivative (finance), derivatives linked to those MBS, collapsed in value. A liquidity crisis spread to global institutions by mid-2007 and climaxed with the bankruptcy of Lehman Brothers in September 2008, which triggered a stock market crash and bank runs in several countries. The crisis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
