Freeport-McMoRan Copper & Gold Inc. (NYSE: FCX ): Freeport-McMoRan Copper & Gold increased 26 cents (or 0.80%) to last market closing price US$32.59 with 15.80 million shares traded, compared to average volume 16.28 million shares. Copper advanced for the first time in five days, rallying from the lowest level in more than five months, amid speculation global policy makers will take steps to stimulate economic growth. Freeport halted production at Grasberg, which has the world's largest recoverable copper reserves, for more than two weeks in February and March after violence flared following a three-month strike last year over pay that hurt global supply and boosted copper prices. Academic studies have shown that insiders traditionally make higher investment returns than ordinary investors. Want to trace the activities of company insiders from now on?
