Energy sector will continue to suffer | In the first nine months of 201314, India imported a little over 3.8 million barrels of crude oil a day – overtaking Japan in import volume. This makes India the third- largest oil importer in the world, behind China and the US.By 2020, the International Energy Agency ( IEA) estimates India will become the world’s largest oil importer. The Indian government, meanwhile, hopes it will achieve energy sufficiency by 2030, making imports unnecessary. It is very unlikely that IEA and the government are both correct in their projections.Note that China has roughly 4.5 times India’s GDP and the US GDP is almost nine times as much as India. India’s oil consumption will rise inevitably as its economy grows larger. By the 2030s, India will need about eight million barrels a day, going by expected GDP and population growth.As of now, India produces slightly less than 0.5 million barrels of crude a day and ramping up domestic production 16 times in the next 15- 20 years would border on the miraculous.It is also difficult to imagine an energy substitution process that drastically reduces the need for crude. This would require major technological breakthroughs.Most likely, India’s import dependency will rise substantially, to around 95 per cent of consumption. This is likely even if domestic sources are tapped efficiently; unconventional shale and coal- bed- methane are developed; massive substitution results via renewable, etc. Most First World nations are net oil importers. None of the importers offer subsidies on acommodity they must import. All ensure fuels are priced at market prices and most add punitive taxes to ensure there isn’t wasteful utilisation. Indian policy should have gone the same way. There should have been an attempt to empower Indian oil and gas explorers and producers.Policy should also be designed to encourage...

Implied Volatility

...yield to maturity as risk-free rate. Data are from Yahoo Finance. 2) Calculating preliminary statistics Using the data, the daily log return was calculated Daily log return = ln (△close pricei+1/close pricei) We assumed that the stock price follows Geometric Brownian Motion with constant mean[pic] and standard deviation[pic]. Therefore, the return of the stock was assumed to be normally distributed with mean [pic] and standard deviation [pic]. So we picked up n-days samples of stock prices and estimated the annualized volatility as follows. Next, we calculated the recent historical volatility. Here, n denotes the number of observations (business day), Si denotes the stock price at the end of the i-th interval (i=0, 1, … , n), [pic] denotes the length of the time interval in years (For daily observations, 1/252(business day)) [pic][pic][pic] [pic] = [pic] Estimated daily volatility S = 0.01042889 Estimated annualized volatility [pic] = 0.1655535 Continuous dividend yield (calculated from the notification) q = 0.028 (Dividend payment= $0.57/share...

Stochastic Volatility

...Supervisor: PETER LØCHTE JØRGENSEN Author: QIAN Zhang (402847) Pricing of principle protected notes embedded with Asian options in Denmark ---- Using a Monte Carlo Method with stochastic volatility (the Heston Model) Aarhus School of Business and Social Science 2011 2 Acknowledgements My gratitude and appreciation goes to my supervisor Peter Lø chte Jø rgensen, for his kind and insightful discussion and guide through my process of writing. I was always impressed by his wisdom, openness and patience whenever I wrote an email or came by to his office with some confusion and difficulty. Especially on access to the information on certain Danish structured products, I have gained great help and support from him. 3 Abstract My interest came after the reading of the thesis proposal on strucured products written by Henrik, as is pointed out and suggested at the last part of this proposal, one of the main limitations of this thesis may be the choice of model. This intrigues my curiosity on pricing Asian options under assumption of stochstic volatility. At first, after the general introduction of strucutred products, the Black Scholes Model and risk neutral pricing has been explained. The following comes the disadvanges of BS model and then moves to the stochastic volatility model, among which the Heston model is highlighted and elaborated. The next part of this thesis is an emricical studying of two structured products embbeded with Asian options in Danish......

Volatility Index

...Exploiting Volatility In the times of recession and variability with the market getting volatile with very far glimpse of normalcy being stored, it would not be a good suggestion to just sit and watch rather it would be a better strategy to make ways to scale up the investment by learning to exploit volatility by diversifying asset allocation, rebalancing portfolio and option strategies. High return volatility definitely increases the fluctuation of the asset class weightings around the target allocation and increases the risk of significant deviation from the target but greater volatility also results in compounded returns . It is substantiated by the situation when the government is spending trillions of dollars to stimulate the growth in the economy and the corporate world is moving ahead with aggressive restructuring. Volatility can be exploited by diversifying the portfolio with bonds as bonds and equities are well correlated and the bonds in the portfolio also dramatically reduces the risk during financial crises. There would be loss but by a lower percentage than in the situation of all equity or lower bond ratio portfolios. The second situation is to avoid risk of market concentration when there is subsequent rise in equity market and then sudden collapse. For this systematic rebalancing is very advantageous as it reduces the downside risk by reducing volatility and investors increase long term portfolio performance by creating alpha and reducing risk. This......

Beta Case

...1) Using Excel’s standard deviations function to calculate the variability of the stock returns of California REIT, Brown Group, and the Vanguard Index 500. Standard Deviation Vanguard 500 4.61% California REIT 9.23% Brown Group 8.17% Brown Group and California REIT stock returns both have large variability compared to the Vanguard 500. Brown Groups variability is substantially larger that of the Vanguard 500, and California REIT variability is even larger as it is double that of the Vanguard 500. While both Brown Group, and California REIT are more risky then the Vanguard 500, California REIT is the most risking of all as the variability of the stock return is the largest of the three. 2) To compare the two portfolio options Beta is offering portfolio 1 containing 99% of equity funds invested in Vanguard 500, and 1% in California REIT, and portfolio 2 containing 99% Vanguard 500, and 1% in Brown Group. Using Excel function’s to find standard deviations and Excel functions to find covariance. First we calculated the monthly return of portfoilio1, and portfolio 2. After doing that we used Excel function standard deviation to find the variance of each portfolio. Standard Deviation Portfolio 1 4.57% Portfolio 2 4.61% Looking at the two portfolios it is apparent that the portfolio containing Brown Group is riskier, because it adds more variability to the portfolio. This contradicts the answer in question...

Volatility Truecrypt

...One of the disclosed pitfalls of TrueCrypt disk encryption is that the master keys must remain in RAM in order to provide fully transparent encryption. In other words, if master keys were allowed to be flushed to disk, the design would suffer in terms of security (writing plain-text keys to more permanent storage) and performance. This is a risk that suspects have to live with, and one that law enforcement and government investigators can capitalize on. The default encryption scheme is AES in XTS mode. In XTS mode, primary and secondary 256-bit keys are concatenated together to form one 512-bit (64 bytes) master key. An advantage you gain right off the bat is that patterns in AES keys can be distinguished from other seemingly random blocks of data. This is how tools like aeskeyfind and bulk_extractor locate the keys in memory dumps, packet captures, etc. In most cases, extracting the keys from RAM is as easy as this: $ ./aeskeyfind Win8SP0x86.raw f12bffe602366806d453b3b290f89429 e6f5e6511496b3db550cc4a00a4bdb1b 4d81111573a789169fce790f4f13a7bd a2cde593dd1023d89851049b8474b9a0 269493cfc103ee4ac7cb4dea937abb9b 4d81111573a789169fce790f4f13a7bd 4d81111573a789169fce790f4f13a7bd 269493cfc103ee4ac7cb4dea937abb9b 4d81111573a789169fce790f4f13a7bd 0f2eb916e673c76b359a932ef2b81a4b 7a9df9a5589f1d85fb2dfc62471764ef47d00f35890f1884d87c3a10d9eb5bf4 e786793c9da3574f63965803a909b8ef40b140b43be062850d5bb95d75273e41 Keyfind progress: 100% Several keys were identified, but......

Volatility Markets.

...Introduction When the stock market goes up one day, and then goes down for the next five, then up again, and then down again, that’s what you call market volatility. Historically, the volatility of the stock market is roughly 20% a year and 5.8% a month, but volatility keeps on changing, so we go through periods of high volatility and low volatility. Analysts and experts have different opinions about what you should do in volatile markets, and how to scope with stock market volatility or the tendency for share prices rising and falling. Analysts. Justin Stewart, co-founder of Seven Investment Management says: “ Crashes happen. If you are a longer-term investor, you should look straight through them and remember the power of compounding dividends, or in cone arising on income.” Andrew Humphries, a director of St James Place Wealth Management, thinks that Diversification is very important and having a portfolio that is solely exposed to one asset class- be it equities, bond or property- is dangerous and all investors should ensure they hold an appropriate range of assets” Andrew Bell, the chief executive of Witan Investment trust advised: “ It is better to buy into fear and cheapness and sell into euphoria and high valuation, as long as you can endure the period before trends reverse. Investors should have this tattooed somewhere to prevent natural human psychology from making them do the opposite. Bill Mott, the manager of PSigma income, said “ in an uncertain world,......

Crisis Period Forecast Evaluation of the Dcc-Garch Model

...for their invaluable direction, patience, and guidance throughout this entire process. Abstract The goal of this paper is to investigate the forecasting ability of the Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroskedasticity (DCC-GARCH). We estimate the DCC’s forecasting ability relative to unconditional volatility in three equity-based crashes: the S&L Crisis, the Dot-Com Boom/Crash, and the recent Credit Crisis. The assets we use are the S&P 500 index, 10-Year US Treasury bonds, Moody’s A Industrial bonds, and the Dollar/Yen exchange rate. Our results suggest that the choice of asset pair may be a determining factor in the forecasting ability of the DCC-GARCH model. I. Introduction Many of today’s key financial applications, including asset pricing, capital allocation, risk management, and portfolio hedging, are heavily dependent on accurate estimates and well-founded forecasts of asset return volatility and correlation between assets. Although volatility and correlation forecasting are both important, however, existing literature has dealt more closely with the performance of volatility models – only very recently has the issue of correlation estimation and forecasting begun to receive extensive investigation and analysis. The goal of this paper is to extend research that has been undertaken regarding the forecasting ability of one specific correlation model, the Dynamic...

...Ibrahim Nasser Khatatbeh May, 2013 Q1: Explain how the option pricing formula developed by black and scholes can be used for common stock and bond valuation. Include in your discussion the consequences of using variance applied over the option instead of actual variance. Its generally known that Black and Scholes model became a standard in option pricing methods , with almost everything from corporate liabilities and debt instruments can be viewed as option (except some complicated instruments), we can modify the fundamental formula in order to fit the specifications of the instrument that will be valued. An argument done by Black and Scholes which was based on the past proposition of Miller and Modigliani a well as assuming some ideal conditions, States that value of the firm is a sum of total value of debt plus the total value of common stock. As well as the fact that in the absence of taxes, the value of the firm is independent of its leverage and the change of debt has no effect on the firm value. V = E + Dm V: value of the firm. E: shareholders right (common stock values). Dm: market value of the debt. As the above equation impose that Equity (common stock values) can be viewed as a call option on the firm value (due to the shareholders limited liability and with consideration that firm debt can be represent as a zero-coupon bond), where exercising the option means that equity holders buy the firm at the face value of debt (which is in this case will......

...Market Volatility: Measures and Results Gary E. Mullins, Ph.D. University of Wisconsin - Stevens Point |   | IntroductionVirtually everyone who is interested in financial markets seems to agree on two things: that markets are now more volatile than ever, and that volatility causes many problems.  Let's look at some recent and not-so-recent articles concerning volatility.   This week turned out to be slower than expected on the IPO  market, as intense volatility on U.S. exchanges prompted many companies to put off much-anticipated debuts.  I am writing to you today to address my concerns about trading in a fast market, a current issue of extreme importance to me. I want to give you my perspective and let you know the steps we at Schwab are taking to support investors during this time of market volatility.  In recent months, there has been a marked increase in price volatility and volume in many stocks, particularly of companies that sell products or services via the Internet (Internet issuers).  In the above quotes, there are two implicit assumptions: that volatility is higher now than it has been in the past, and that this volatility is somehow bad.  In the first article, it assumes that (obviously) increased volatility has caused firms to delay their Initial Public Offerings (IPO's).  Next, Schwab believes that investors need special support because of the high volatility inherent in today's market.  Finally, Barrett appears to be more concerned about volatility......

A Novel Simple but Empirically Consistent Model for Stock Price and Option Pricing

...model for stock price dynamics and option pricing, which not only has the same analyticity as log-normal and Black-Scholes model, but can also capture and explain all the main puzzles and phenomenons arising from empirical stock and option markets which log-normal and Black-Scholes model fail to explain. In addition, this model and its parameters have clear economic interpretations. Large sample empirical calibration and tests are performed and show strong empirical consistency with our model’s assumption and implication. Immediate applications on risk management, equity and option evaluation and trading, etc are also presented.

Medeiros2 2 School of Economics and Commerce, University of Western Australia Department of Economics, Pontifical Catholic University of Rio de Janeiro, Rio de Janeiro, Brasil 1 Downloaded At: 15:53 5 September 2008 This article reviews the exciting and rapidly expanding literature on realized volatility. After presenting a general univariate framework for estimating realized volatilities, a simple discrete time model is presented in order to motivate the main results. A continuous time specification provides the theoretical foundation for the main results in this literature. Cases with and without microstructure noise are considered, and it is shown how microstructure noise can cause severe problems in terms of consistent estimation of the daily realized volatility. Independent and dependent noise processes are examined. The most important methods for providing consistent estimators are presented, and a critical exposition of different techniques is given. The finite sample properties are discussed in comparison with their asymptotic properties. A multivariate model is presented to discuss estimation of the realized covariances. Various issues relating to modelling and forecasting realized volatilities are considered. The main empirical findings using univariate and multivariate methods are......

However, the implied volatility surface also changes dynamically over time in a way that is not taken into account by current modelling approaches, giving rise to ‘Vega’ risk in option portfolios. Using time series of option prices on the SP500 and FTSE indices, we study the deformation of this surface and show that it may be represented as a randomly fluctuating surface driven by a small number of orthogonal random factors. We identify and interpret the shape of each of these factors, study their dynamics and their correlation with the underlying index. Our approach is based on a Karhunen–Lo` ve e decomposition of the daily variations of implied volatilities obtained from market data. A simple factor model compatible with the empirical observations is......
