Financial engineeringFinancial engineering is a multidisciplinary field involving financial theory, methods of engineering, tools of mathematics and the practice of programming. It has also been defined as the application of technical methods, especially from mathematical finance and computational finance, in the practice of finance. Financial engineering plays a key role in a bank's customer-driven derivatives business — delivering bespoke OTC-contracts and "exotics", and implementing various structured products — which encompasses quantitative modelling, quantitative programming and risk managing financial products in compliance with the regulations and Basel capital/liquidity requirements.
Confidence regionIn statistics, a confidence region is a multi-dimensional generalization of a confidence interval. It is a set of points in an n-dimensional space, often represented as an ellipsoid around a point which is an estimated solution to a problem, although other shapes can occur. Confidence interval#Meaning and interpretation The confidence region is calculated in such a way that if a set of measurements were repeated many times and a confidence region calculated in the same way on each set of measurements, then a certain percentage of the time (e.
Confidence distributionIn statistical inference, the concept of a confidence distribution (CD) has often been loosely referred to as a distribution function on the parameter space that can represent confidence intervals of all levels for a parameter of interest. Historically, it has typically been constructed by inverting the upper limits of lower sided confidence intervals of all levels, and it was also commonly associated with a fiducial interpretation (fiducial distribution), although it is a purely frequentist concept.
Loi du χ²En statistiques et en théorie des probabilités, la loi du centrée (prononcé « khi carré » ou « khi-deux ») avec k degrés de liberté est la loi de la somme de carrés de k lois normales centrées réduites indépendantes. La loi du est utilisée en inférence statistique et pour les tests statistiques notamment le test du χ2. La loi du χ2 non centrée généralise la loi du . Soient k variables aléatoires X, ... , X indépendantes suivant la loi normale centrée et réduite, c'est-à-dire la loi normale de moyenne 0 et d'écart-type 1.
Modélisation financièreLa modélisation financière consiste à représenter une situation financière grâce à un modèle mathématique, en fonction de différents paramètres. La modélisation financière facilite ainsi la prise de décision, en permettant de simuler divers scénarios et d’aboutir à des recommandations. La modélisation s’applique principalement à deux grands domaines de la finance, la finance d’entreprise et la finance de marché.
Ratio distributionA ratio distribution (also known as a quotient distribution) is a probability distribution constructed as the distribution of the ratio of random variables having two other known distributions. Given two (usually independent) random variables X and Y, the distribution of the random variable Z that is formed as the ratio Z = X/Y is a ratio distribution. An example is the Cauchy distribution (also called the normal ratio distribution), which comes about as the ratio of two normally distributed variables with zero mean.
Operational risk managementOperational risk management (ORM) is defined as a continual recurring process that includes risk assessment, risk decision making, and the implementation of risk controls, resulting in the acceptance, mitigation, or avoidance of risk. ORM is the oversight of operational risk, including the risk of loss resulting from inadequate or failed internal processes and systems; human factors; or external events. Unlike other type of risks (market risk, credit risk, etc.) operational risk had rarely been considered strategically significant by senior management.
Loi stableLa loi stable ou loi de Lévy tronquée, nommée d'après le mathématicien Paul Lévy, est une loi de probabilité utilisée en mathématiques, physique et analyse quantitative (finance de marché). On dit qu'une variable aléatoire réelle est de loi stable si elle vérifie l'une des 3 propriétés équivalentes suivantes : Pour tous réels strictement positifs et , il existe un réel strictement positif et un réel tels que les variables aléatoires et aient la même loi, où et sont des copies indépendantes de .
Financial risk modelingFinancial risk modeling is the use of formal mathematical and econometric techniques to measure, monitor and control the market risk, credit risk, and operational risk on a firm's balance sheet, on a bank's trading book, or re a fund manager's portfolio value; see Financial risk management. Risk modeling is one of many subtasks within the broader area of financial modeling. Risk modeling uses a variety of techniques including market risk, value at risk (VaR), historical simulation (HS), or extreme value theory (EVT) in order to analyze a portfolio and make forecasts of the likely losses that would be incurred for a variety of risks.
Diversification (finance)La diversification est, en finance, le processus par lequel un gestionnaire d'actifs alloue ses capitaux à des investissements de différents types. La diversification permet d'éviter d'être exposé aux risques d'une classe d'actifs. En investissant dans un grand nombre d'actifs, le gestionnaire d'actifs assure une moindre volatilité à son portefeuille. La diversification consiste en le choix, par un gestionnaire d'actifs, de multiplier le type d'actifs contenu dans son portefeuille d'actifs, ainsi que de multiplier les actifs eux-mêmes.
Loi normale multidimensionnelleEn théorie des probabilités, on appelle loi normale multidimensionnelle, ou normale multivariée ou loi multinormale ou loi de Gauss à plusieurs variables, la loi de probabilité qui est la généralisation multidimensionnelle de la loi normale. gauche|vignette|Différentes densités de lois normales en un dimension. gauche|vignette|Densité d'une loi gaussienne en 2D.

Professional certification in financial servicesFollowing is a partial list of professional certifications in financial services, with an overview of the educational and continuing requirements for each; see and for all articles. As the field of finance has increased in complexity in recent years, the number of available designations has grown, and, correspondingly, some will have more recognition than others.
