"Insider trading is part of my investment strategy," one defendant boasted on an internet message board. : The SEC charged six people with insider trading this week, busting a Silicon Valley ring that had generated $1.7 million in illicit profits. At the center of the SEC's actions was Nathaniel Brown, a revenue officer for San Jose-based Infinera, a publicly listed network equipment manufacturer. Brown is alleged to have passed insider information to his best friend, Benjamin Wylam, who in turn tipped off four others to make illegal trades.
