I dont think that 100 shares transactions look suspecious at all. That's pretty typical. Just randomly checked the FMCN quote and see a lot of 100 shares as well. You can try to check other stocks with similar daily volume and PPS. http://www.nasdaq.com/aspx/NLStrades.aspx?pageno=2&&symbol=FMCN&selected=FMCN&time=13
