Hi Skol, I'm not talking about manipulators of gold or silver, those markets are so big that you'd think it would be difficult. But insiders in even reasonably large listed companies can stage the release of data to the market, can alter the price of two shares before a pre-arranged merger date to meet a magic multiple, buy shares in an unannounced merger target, pursue policies to shake out disaffected or smaller investors, etc. Dig a bit deeper into company politics and board members' other interests, and you will find these situations that are just too coincidental.
