Advantages Of The EGARCH Model
The EGARCH model has a number of advantages over the GARCH (p,q) model. The most important one is its logarithmic specification, which allows for relaxation of the positive constraints among the parameters. Another advantage of the EGARCH model is that it incorporates the asymmetries in stock return volatilities. Another advantage of the EGARCH model is that it successfully captures the persistence of volatility shocks. Based on these advantages, we apply the EGARCH model for estimating the volatility of the Emerging equity market. Table 11 and 12: Here the null hypothesis states that coefficients are not significant. From the above two tables it can be seen that all Coefficient are significant for India, China, Mexico and Turkey. For Brazil …show more content…
VaR models were developed to estimate the exposure of a portfolio to market risk (Jorion, 2007). VaR has also emerged as standard quantitative measure of market risk within most financial institutions; moreover, this method also forms the basis for a host of risk controls (e.g., position limits and margin requirements) (IMF, 2007). There are various methods, or approaches, to measure VaR. Differences among these approaches arise from the model applied to the estimation of the expected changes in prices. Table 16 in annexure presents the VaR failure rates for the emerging equity markets, reported at the 95 percent probability …show more content…
Ten years data of six emerging equity markets namely Brazil, china, India, Mexico, turkey and Russia has been taken for study purpose. VaR is calculated to estimate the probability of risk in the portfolio of these nations. Initially for data checking purpose, ADF and PP tests were applied to check the stationary of data, the result of which indicated that the data was stationary at level. Further descriptive statistics were applied to check the normality of data. This included Skweness, kurtosis and Jarque Bera. The ARCH (LM) test i.e. Lagrange multiplier (LM) test for autoregressive conditional heteroskedasticity in residuals was applied. The data was normally distributed. The arch effect was found in all the emerging equity markets which implied that there was impact of previous day’s returns on the present

We could successfully conclude that our null hypothesis of the urine having no effect on the mice was wrong. This is because of P-value is <0.05 and represents that are data was statistically
Calgary-Cambridges Model
293 Words | 2 PagesThe following is a case study focusing on the assessment and examination of a female patient presenting with symptoms of abdominal pain and vaginal bleeding during pregnancy to an emergency gynaecology and pregnancy assessment clinic. Names have been changed to maintain anonymity in line with the Nursing and Midwifery Council (NMC) (2015). The Calgary-Cambridge model of assessment (Kurtz and Silverman 1996) was used to guide the practitioner through the health assessment process. The guide provides an easy-to-use structure that complements nursing 's traditional holistic assessment approach.
Summary: Share Of EOG Resources
941 Words | 4 PagesEOG Resources – Share of EOG Resources (NYSE:EOG) picked up approximately 18%, since its 52 weeks of low of $60.24 a share on January 20, due a 7% increase in the oil price so far this year. This should have a positive impact on its financial performance in the first-quarter of 2016, considering the fact that EOG is taking various steps to survive this downturn efficiently. This includes, reduction in costs & capital spending, improving operational efficiencies through continued focus on innovative technology, shifting focus to premium locations that generates 30% rate of return at $40 per barrel of oil prices and improving balance sheet. Let us look at these initiatives in details. Reduction in costs and capital expenditure
In The Gloaming Analysis
584 Words | 3 PagesIn this short story, “In the Gloaming” by Alice Elliott Dark, the main characters learn that you should spend as much time as possible with family, make and never forget memories together, and how to accept death. Although the characters learn these lessons the hard way, in the end they come to understand the value of them. People will always tell you how valuable time is, but I didn't realize how true this statement is until reading this short story. In the story, it is mentioned how Laird’s dad and mom didn’t spend a lot of time with him. In the story, it states, “She had as much of him now as she had when he was an infant.”

Similarities And Differences Between The Single Index Model And Capital Asset Pricing Model
1217 Words | 5 PagesOutline the similarities and differences between the Single Index Model (SIM) and the Capital Asset Pricing Model (CAPM). Justify which of the two models makes a better assessment of return of a security (25 marks). To reduce a firm’s specific risk or residual risk a portfolio should have negative covariance or rather it should have no variance at all, for large portfolios however calculating variance requires greater and sophisticated computing power. As such, Index models greatly decrease the computations needed to calculate the optimum portfolio. The use of such Index models also eliminates illogical or rather absurd results.
The ABC-E Model
1795 Words | 8 PagesThe purpose of this assignment, I will critically discuss and analyse the use of the ABC-E model, when assessing and engaging with a new client. The ABC-E model of emotion is known by a bio-psychosocial model of mental health care which enables a client to understand there autonomic, behavioural and cognitive symptoms in their environment to get a much deeper insight, into how the client may be feeling. Nursing assessments are a key component to mental health nursing care. It is a decision-making process based on the collection of information that gives an overall estimation of the consumer and their circumstances (Barker 2004).
Pros And Cons Of Decision Making Model
789 Words | 4 PagesThere are four major decision-making models- rational, bounded rationality, incremental and garbage can models. In the following, pros and cons of each model will be discussed and explain why Incremental and Garbage Can Models can best describe the decision made during the Cuban Missile Crisis. Rational model is a cognitive process, which the decision-makers run through rational steps. The steps refer to definition of problems, identification and evaluation of alternative policies, implementation of the best policies among all and finally monitoring of effects, ran through a unitary decision-maker (Taylor, 1998). Theoretically, the model can search for the best solution to the problem based on the comprehensive consideration.
Advantages Of Risk Metrics
919 Words | 4 PagesGiven the risk considerations provided in the RCD tool and the Portfolio Theory, the next step should be understanding the available risk/return metrics and determining an optimal mix of assets. Risk Metrics and Advantage/Disadvantages There are two risk metrics used in the model, Conditional Tail Expectation (CTE) and Value at Risk (VaR). These two metrics both look at the tail of the distribution. VaR is a measure of particularly poor outcomes in a stochastic projection. Its major shortcoming is its lack of statistical coherency.
Lehman Brothers Red Flags Case Study
985 Words | 4 PagesIn order to identify red flags for risk management from various financial risk ratios, models, and traditional ratios for Bear Stearns and Lehman Brothers, we list our calculation results below. Based on our calculation, Bear Stearns got 15 red flags, which occupied 68% of total red flags, while Lehman Brothers 12 red flags, occupying 55% of total red flags. These two numbers were high even compared with other investment banks, and companies committed fraudulent activities. In summary, both Lehman Brothers and Bear had high possibility of going bankruptcy.
