Well Made Stock Market Widget Pack
This plugin will make two new widgets available on your widgets menu. One will allow you to show all the information on one single stock while the other will allow you to build a comparison table with as many stocks as you want. All settings are easily handled through the widgets themselves.
Each widget can be used more than once on the same page or on different pages, allowing you to build comparison tables divided by sectors or funds or if you are using widgetized pages build up pages that dive deeper into the numbers of multiple companies.
These widgets will adapt nicely to the design of your current theme with no need for customization. Check the plugin screenshots to see how good it looks on 10 different themes picked at random!
