Nasdaq serves up Twitter stock buzz on iPhone

The QFolio App is designed for the average novice investor to the active trader, says Nasdaq. It offers access to real-time pre-market, regular session and after hours trading data alongside a stock search facility.

Users can monitor the performance of their portfolio and set up watch lists to track particular stocks of interest.

The app also comes with a built-in StockTwits feature for users to drill down into the real-time Twitter buzz on particular stocks.
