Stock Investment Guide (SIG) lets you obtain information for any stock quote and analyze its performance over a period of time. The analysis tab will give you forecast and calculate estimates for expected prices and buy/sell risks. SIG does this automatically, using the data you imported from Internet. SIG provides three graphs to read your stock info: performance, growth and data. You can adjust and scale graphs and move factors up or down. Disappointingly though, you'll have to make with the factors at hand, as there is no way of adding new ones to your graph. We found it very easy to generate and print reports like company performance or stock summary. Even though we came upon a few glitches in the app and the application was prone to crashing, especially when adjusting graphs, SIG is a good tool to preview in seconds quote information, analysis and forecasts.
