Drawdown of Historical Stock Prices
http://www.maplesoft.com/applications/view.aspx?SID=153624&ref=Feed
<p>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.</p>
<p>This application:</p>
<ul>
<li>downloads historical stock prices from Yahoo Finance for a chosen ticker symbol (this requires a connection to the Internet),</li>
<li>defines a procedure that calculates the drawdown of the historical stock price</li>
<li>and plots the drawdown against the adjusted close price of the asset</li>
</ul>
<p>By changing the ticker symbol and the two dates, you can examine drawdown of any stock between any period.</p>
<p>The application uses Maple 18's improved Internet connectivity; you can now download data from a URL into a matrix using <span><a href="/support/help/Maple/view.aspx?path=ImportMatrix">ImportMatrix()</a></span>.</p><img src="/view.aspx?si=153624/2def9a8f2111f9b47d0bee568aed6035.gif" alt="Drawdown of Historical Stock Prices" align="left"/><p>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=153516&ref=Feed
<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.

http://www.maplesoft.com/applications/view.aspx?SID=121119&ref=Feed
<p>This application examines how floating exchange rates affect the macroeconomic performance of an economy. In particular, it shows how an economy can maintain its internal and external balances with a floating exchange rate regime. The macroeconomic performance under the floating exchange rates is analysed in the framework of internal shocks to it from govenment marcroeconomic policies, such as monetary policy (money supply changes) and fiscal policy (government spending changes). Namely, the developed application from a set of sample data shows that the overall effect of these two policies to the macroeconomic performance of the country is different. The monetary policy proved to be more effective under the floating exchange rate and it increased real domestic production when the money supply was increased. On the other hand, fiscal policy proved to be effective under the floating exchange rates only when capital mobility is low. With higher capital mobility, the fiscal policy tended to be less effective than the monetary policy. </p><img src="/view.aspx?si=121119/384814\f10ad4ab24fcc5bdb42df2c8d27b4676.gif" alt="Floating Exchange Rate and Internal Balance" align="left"/><p>This application examines how floating exchange rates affect the macroeconomic performance of an economy.

http://www.maplesoft.com/applications/view.aspx?SID=120866&ref=Feed
<p>This application demonstrates how international trade occures in a simple case between two countries and in one product market. The application starts with given supply and demand functions in two separate countries, country A and country B. Then it proceeds to identify domestic equilibrium prices and quantities in these two countries for a given product market. The difference between the domestic prices plays a role in determining the direction of trade flows, i.e. exports and imports. In this given application, country A imports and country B exports products as the domestic price is lower in country B than in country A. Then the application shows how equilibrium international price and international quantity (exports and imports) can be identified given specific domestic supply and demand functions of the two countries. Moreover, this application also demonstrates interactively how setting import tariff and import quota in country A can restrict international trade and how this will affect import price, quantity, and welfare of economic agents in importing country. The application is created for study purposes of international trade model by using Maple program.</p><img src="/view.aspx?si=120866/384396\3d8359703bf9dcce1b49dfbc4fccfc5d.gif" alt="International Trade Model" align="left"/><p>This application demonstrates how international trade occures in a simple case between two countries and in one product market.

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.

Financial engineers and quantitative analysts often exploit network services to retrieve stock quotes. A large number of services exist, including paid-for real-time feeds from Bloomberg and Reuters. Yahoo, however, provide a free service that is delayed by fifteen minutes.
The Interactive Stock Quote Importer in this worksheet will import quotes (including historical data) from Yahoo for a series of user-specified NYSE stock symbols. This application
provides text fields for specifying up to five ticker symbols,
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.
