Billionare Joseph Lewis Raises Stake in Bear Stearns

Bear Stearns said on Friday that shareholder Joseph Lewis raised his stake in the company to 8.01 percent.

The billionaire, who made his fortune trading currencies, took a 7 percent stake in Bear Stearns in September, snapping up $860.4 million worth of the investment bank's sagging stock to become one of its largest shareholders in less than a month.
