https://www.maplesoft.com/applications/view.aspx?SID=154474&ref=Feed
Some Markov chains have very useful characteristics. Specially in the case of credit risk, we are interested in concept such as the probability of default, the passing of time between an initial state and default and topics such as the setting where we have more than one Markov-driven economic agent and where the credit status of one may affect the others. We will see that for such special cases with a transition matrix that satisfies some well defined conditions, it is possible to compute the alluded probabilities with just a few matrix operations. We use examples to illustrate the application of the most commonly used theorems of Markov Chains.<img src="https://www.maplesoft.com/view.aspx?si=154474/markov.PNG" alt="Frequently Used Markov Chain Models: A Heuristic Approach" style="max-width: 25%;" align="left"/>Some Markov chains have very useful characteristics.

This application explores the use of Machine Learning routines to develop a better sense about the Machine-Learning approach to financial series forecasting. As an exercise, we will investigate whether past performance of the stock market can give us any hints about future performance by simply focusing on the shape of the time series of the Market Index.

https://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.

https://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="https://www.maplesoft.com/view.aspx?si=153994/omega_ratio.png" alt="Portfolio Optimization with the Omega Ratio" style="max-width: 25%;" align="left"/>Traditional investment performance benchmarks, like the Sharpe Ratio, approximate the returns distribution with mean and standard deviation.

https://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.
