Critical Insider Trade Reports for CIENA, AK Steel, Gilead Sciences, RF Micro Devices, & MannKind; Reported by Insiderslab.com

VANCOUVER, BC--(Marketwire - December 17, 2010) - Insiderslab.com today issued reports highlighting the respectable insider trade for CIENA (CIEN), AK Steel (AKS), Gilead Sciences (GILD), RF Micro Devices (RFMD), & MannKind (MNKD).

Besides reporting direct ownerships and transactions, corporate insiders have to file their indirect holdings made by their relatives as well. SEC even further indicates that insiders also own indirect ownership of the partnership they participated in. However, insiderslab.com suggests investors pay more attention to those direct holding trades, since insiders are more likely to practice more discretion when they registered the shares under their own names.
