Tracinda to Boost Chrysler Stake: Billionaire investor Kirk Kerkorian, who received tenders for 58.4 million Chrysler Corp. shares--many more than he can buy--said he will purchase about 24% of them starting today. Kerkorian’s Tracinda Corp. will stick to plans to buy 14 million shares for about $700 million. The other 44.4 million shares tendered in Tracinda’s $50-a-share offer, which expired July 25, will be returned to shareholders, the company said. With the purchases, Tracinda will directly own about 13.1% of Chrysler’s outstanding shares.
