Does someone want Nabisco Group Holdings more than Carl Icahn? Mr. Icahn last week bid $16 per share for the 90% of NGH he doesn't own. NGH has invited other bids. Investors bid up the price of NGH stock, but it hovered below $16 in late-week trading. NGH's top managers have been warmly praised by food analysts for their turnaround efforts, but NGH stock has fallen from more than $20 last summer to under $10 per share this year. In trading Friday, NGH closed at $15.13, up 25.38% for the week.
