Local Volatility and Implied Volatility
http://www.maplesoft.com/applications/view.aspx?SID=4878&ref=Feed
This application explores two different methods of exploring financial data. The first example examines fitting an implied volatility surface based on data from S&P 500 call options. The second computes option prices and models the local volatility for simulated market data.<img src="/view.aspx?si=4878/volatility.png" alt="Local Volatility and Implied Volatility" align="left"/>This application explores two different methods of exploring financial data.

http://www.maplesoft.com/applications/view.aspx?SID=153993&ref=Feed
This application calculates the fair value of a stock, given the current market prices and several growth assumptions. Simply pick an industry, stock exchange, and then a company.
<BR><BR>
Maple then downloads the current market share price, EPS (for the trailing 12 months) and dividends (for the trailing 12 months) from Yahoo Finance (hence a connection to the web is needed). Given a series of growth assumptions, a fair value is then calculated. The valuation process is described at the bottom of this application, and is most appropriate for stable companies with a history of dividend payments.
<BR><BR>
The stock is undervalued if the fair value is greater than the current market price, and vice-versa.
<BR><BR>
This application comes with an Excel spreadsheet with a list of over 25000 companies across multiple industries and international exchanges, and their corresponding ticker symbols.<img src="/view.aspx?si=153993/stock_overvalued.png" alt="Is a Stock Overvalued or Undervalued?" align="left"/>This application calculates the fair value of a stock, given the current market prices and several growth assumptions.

http://www.maplesoft.com/applications/view.aspx?SID=153992&ref=Feed
The drawdown of a stock indicates how much time it's spent "underwater" - it's essentially the percentage drop of its price from a peak to a trough, with the drawdown resetting to zero if a previous high is reached. The drawdown of a stock is a valuable risk measure and is employed by traders to gauge volatility.

This application:

<LI>downloads historical stock prices from Yahoo Finance for a chosen ticker symbol,
<LI>defines a procedure that calculates the drawdown of the historical stock price,

By changing the ticker and the dates, you can examine drawdown of any stock between your chosen dates.<img src="/view.aspx?si=153992/Drawdown.png" alt="Drawdown of Historical Stock Prices" align="left"/>The drawdown of a stock indicates how much time it's spent "underwater" - it's essentially the percentage drop of its price from a peak to a trough, with the drawdown resetting to zero if a previous high is reached.

http://www.maplesoft.com/applications/view.aspx?SID=153994&ref=Feed
Traditional investment performance benchmarks, like the Sharpe Ratio, approximate the returns distribution with mean and standard deviation. This, however, assumes the distribution is normal. Many modern investments vehicles, like hedge funds, display fat tails, and skew and kurtosis in the returns distribution. Hence, they cannot be adequately benchmarked with traditional approaches.
<BR><BR>
One solution, proposed by Shadwick and Keating in 2002 is the Omega Ratio. This divides the returns distribution into two halves the area below a target return, and the above a target return. The Omega Ratio is simply the former divided by the latter. A higher value is better.
<BR><BR>
This application finds the asset weights that maximize the Omega Ratio of a portfolio of ten investments, given their simulated monthly returns and a target return.
<BR><BR>
This is a non-convex problem, and requires global optimizers for a rigorous solution. However, a transformation of the variables (only valid for Omega Ratios of over 1) converts the optimization into a linear program.
<BR><BR>
This application implements both approaches, the former using Maple's Global Optimization Toolbox, and the latter using Maple's linear programming features. For the data set provided in this application, both approaches give comparable results.<img src="/view.aspx?si=153994/omega_ratio.png" alt="Portfolio Optimization with the Omega Ratio" align="left"/>Traditional investment performance benchmarks, like the Sharpe Ratio, approximate the returns distribution with mean and standard deviation.

<p>The application presents and definition, creation and handling of jump-diffusion processes. In general, jump-diffusion is an extension to the theory of stochastic processes where the underlying parameters exhibit shocks and "jump" to their new values. Stochasticity with jumps is well recognised in several scientific branches including physics, chemistry, biology, but also economic and finance. The application looks at the example of the last-mentioned fields where the theory of jump-diffusions has been particularly actively researched and applied.</p><img src="/view.aspx?si=153516/Jump_image1.jpg" alt="Jump-diffusion stochastic processes with Maple" align="left"/><p>The application presents and definition, creation and handling of jump-diffusion processes.

allows the user to pick those quantities they want to import with check boxes,
summarises the data in a table,
assigns the values to variables for further processing and analysis.<img src="/view.aspx?si=103805/thumb.jpg" alt="An Interactive Stock Quote Importer" align="left"/>Financial engineers and quantitative analysts often exploit network services to retrieve stock quotes.

http://www.maplesoft.com/applications/view.aspx?SID=103793&ref=Feed
The Finance package is new in Maple 15. It contains many tools for advanced financial modeling, as well as accessible tools for personal finance. On the personal finance side, there are tools that can be used for computing with mortgages or retirement packages. The financial modeling tools include a wide range of stochastic processes that can be used to model option prices, such as Brownian motion, Ito processes, an SVJJ process, and more. It also includes tools to compose complex processes out of these building blocks. You can also create, manipulate, and analyze many types of financial instruments, such as American, Bermudan, and European options and swaptions and several types of bonds; short rate models; term structures of interest rates; and cash flows. The instruments can then be priced using analytic methods, lattice methods or Monte Carlo simulation - all using one of many date arithmetic conventions. Finally, the processes occurring in the package can be visualized in several ways.<img src="/view.aspx?si=103793/thumb.jpg" alt="Financial Modeling in Maple" align="left"/>The Finance package is new in Maple 15.

http://www.maplesoft.com/applications/view.aspx?SID=100528&ref=Feed
<p>Copula is a constructor function for multivariate distribution from univariate marginals. It is a method to link univariate samples, not necessarily from identical distributions, into joint multivariate distributions. In this way, copulas are more generic and flexible functions to study dependency arising from multivariate distributions.</p>
<p>Conceptually, copulas are based on transformation of the underlying marginal into new derived variable with uniform distribution. Consequently, any multivariate distribution can be expressed in the form of copula function. If each marginal is continuous then copula is unique. Sklar in 1959 was the first to point this out.</p>
<p>Copulas represent a broad set of functions and they generally differ by (i) number of dependency factors and (ii) construction complexity. The choose of copula depends on the nature of the multivariate study and fitting objectives to an underlying data.</p><img src="/view.aspx?si=100528/maple_icon.jpg" alt="Copula function in multivariate dependency analysis" align="left"/><p>Copula is a constructor function for multivariate distribution from univariate marginals.

<p>In this application we show how Maple can handle financial options models that have become popular in commodity finance. The financial trading of commodities has dramatically increased over past years as finance community started to look for non-standard instruments uncorrelated with the traditional financial products such as stocks, bonds, rates and currencies. Commodities, unlike their financial counterparts, require different approach to the process modeling: (i) commodities exhibit seasonality effects, (ii) commodity futures are exposed to many deformation modes, (iii) futures volatility is driven by the "Samuelson" effect that causes its drop as the expiry time shortens.</p><img src="/view.aspx?si=35126/thumb.jpg" alt="Maple for Commodity Finance" align="left"/><p>In this application we show how Maple can handle financial options models that have become popular in commodity finance.
