Stock Alert - Tablet Edition is a android tablet app that has real time quotes from stock exchanges around the world. You can set price alerts from currencies to commodities.
I have been using Stock Alert for the phone. This Tablet specific version is amazing. This has to be in the Top 10 Apps for the Android Tablet. It gives current news for a stock, charting of the stock's activity for the day.
