Two weeks ago Tom Winnifrith and Lucian Miers recorded a series of four videos which first appeared on their Nifty Fifty website. This video covers Globo (GBO), blinkx (BLNX), Avanti Communications (AVN), Iofina (IOF) and Quindell (QPP).
The other two videos cover companies including Gulf Keystone (GKP), Mothercare (MTC) and Naibu (NBU) but can be accessed only on the Nifty Fifty.
