Churr Software (http://churr.com) has announced Stock Investment Guide 3.1.3, an update of the stock analysis tool for Mac OS X. The update adds the ability to print portfolio listings, a calculation of the sustainable growth rate. Other new features include a new price history graph, automatic updating of dividend yields in portfolio views, and more.

It provides investors with tools to analyze a company’s earnings history to help forecast what earnings could be in five years. The Stock Investment Guide can then tell the investor if the current PE ratio is in-line with its historical price range.

Churr Software will be having a Black Friday & Cyber Monday sale. Customers will be able to purchase the Stock Investment Guide during the sale for a 15% discount. The normal price of the Stock Investment Guide is US$80, but will be available during this limited time sale for $68.
