Liquidity At Risk
The Liquidity-at-Risk (short: LaR) is a measure of the liquidity risk exposure of a financial portfolio. It may be defined as the net liquidity drain which can occur in the portfolio in a given risk scenario. If the Liquidity at Risk is greater than the portfolio's current liquidity position then the portfolio may face a liquidity shortfall. Liquidity at Risk is different from other measures of risk based on total loss, as it is based on an estimate of cash losses, or liquidity outflows, as opposed to total loss. Definition The Liquidity-at-Risk of a financial portfolio associated with a stress scenario is the net liquidity outflow resulting from this stress scenario: The liquidity shortfall in a stress scenario is thus given by the difference between the Liquidity-at-Risk associated with the stress scenario and the amount of liquid assets available at the point where the scenario occurs. The concept of Liquidity at Risk is used in stress testing. It is conditional on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquidity Risk
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. Types Market liquidity – An asset cannot be sold due to lack of liquidity in the market – essentially a sub-set of market risk. This can be accounted for by: * Widening bid–offer spread * Making explicit liquidity reserves * Lengthening holding period for value at risk (VaR) calculations Funding liquidity – Risk that liabilities: * Cannot be met when they fall due * Can only be met at an uneconomic price * Can be name-specific or systemic Causes Liquidity risk arises from situations in which a party interested in trading an asset cannot do it because nobody in the market wants to trade for that asset. Liquidity risk becomes particularly important to parties who are about to hold or currently hold an asset, since it affects their ability to trade. Manifestation of liquidity r ...

Margin At Risk
The Margin-at-Risk (MaR) is a quantity used to manage short-term liquidity risks due to variation of margin requirements, i.e. it is a financial risk occurring when trading commodities. It is similar to the Value-at-Risk (VaR), but instead of simulating EBIT it returns a quantile of the (expected) cash flow distribution. To do so, MaR requires (1) a currency, (2) a confidence level (e.g. 90%) and (3) a holding period (e.g. 3 days). The idea is that a given portfolio loss will be compensated by a margin call by the same amount. The MaR quantifies the "worst case" margin-call and is only driven by market prices.

Value At Risk
Value at risk (VaR) is a measure of the risk of loss for investments. It estimates how much a set of investments might lose (with a given probability), given normal market conditions, in a set time period such as a day. VaR is typically used by firms and regulators in the financial industry to gauge the amount of assets needed to cover possible losses. For a given portfolio, time horizon, and probability ''p'', the ''p'' VaR can be defined informally as the maximum possible loss during that time after excluding all worse outcomes whose combined probability is at most ''p''. This assumes mark-to-market pricing, and no trading in the portfolio. For example, if a portfolio of stocks has a one-day 95% VaR of $1 million, that means that there is a 0.05 probability that the portfolio will fall in value by more than $1 million over a one-day period if there is no trading. Informally, a loss of $1 million or more on this portfolio is expected on 1 day out of 20 days (because of 5% pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Profit At Risk
Profit-at-Risk (PaR) is a risk management quantity most often used for electricity portfolios that contain some mixture of generation assets, trading contracts and end-user consumption. It is used to provide a measure of the downside risk to profitability of a portfolio of physical and financial assets, analysed by time periods in which the energy is delivered. For example, the expected profitability and associated downside risk (PaR) might be calculated and monitored for each of the forward looking 24 months. The measure considers both price risk and volume risk (e.g. due to uncertainty in electricity generation volumes or consumer demand). Mathematically, the PaR is the quantile of the profit distribution of a portfolio. Since weather related volume risk drivers can be represented in the form of historical weather records over many years, a Monte-Carlo simulation approach is often used. Example If the confidence interval for evaluating the PaR is 95%, there is a 5% probabili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematical Finance
Mathematical finance, also known as quantitative finance and financial mathematics, is a field of applied mathematics, concerned with mathematical modeling of financial markets. In general, there exist two separate branches of finance that require advanced quantitative techniques: derivatives pricing on the one hand, and risk and portfolio management on the other. Mathematical finance overlaps heavily with the fields of computational finance and financial engineering. The latter focuses on applications and modeling, often by help of stochastic asset models, while the former focuses, in addition to analysis, on building tools of implementation for the models. Also related is quantitative investing, which relies on statistical and numerical models (and lately machine learning) as opposed to traditional fundamental analysis when managing portfolios. French mathematician Louis Bachelier's doctoral thesis, defended in 1900, is considered the first scholarly work on mathematical fi ...

Financial Risk
Financial risk is any of various types of risk associated with financing, including financial transactions that include company loans in risk of default. Often it is understood to include only downside risk, meaning the potential for financial loss and uncertainty about its extent. A science has evolved around managing market and financial risk under the general title of modern portfolio theory initiated by Dr. Harry Markowitz in 1952 with his article, "Portfolio Selection". In modern portfolio theory, the variance (or standard deviation) of a portfolio is used as the definition of risk. Types According to Bender and Panz (2021), financial risks can be sorted into five different categories. In their study, they apply an algorithm-based framework and identify 193 single financial risk types, which are sorted into the five categories market risk, liquidity risk, credit risk, business risk and investment risk.
