Kerkorian is noted for doing what Warren Buffett, Eddie Lampert, and others have done. Buy up a floundering business, sell off the surplus assets and real estate, and drive up the stock price of the remaining bits. Buffett took a moribund shirt company and spun it into a huge moneymaker.
In Lampert's case (he's the brains behind the Sears / Kmart merger), he took Kmart stock from from $15 a share to over $100 before leveraging the Sears buyout (he was already the largest Sears shareholder before the deal). Since then, Lampert's MO has been to sell off closed stores in urban areas where retail space is at a premium, versus do anything creative or visionary with the stores that remain open. His 'innovative' idea of offering a limited selection of Craftsman tools at Kmart stores hasn't had much of an impact.
Buffet didn't tinker with the management of the companies Berkshire Hathaway bought. Lampert tinkers quite a bit more, and the results have not been as strong. I think Kerkorian is more likely to emulate Lampert than Buffett. I expect he'll play puppet master, installing and firing managers at a whim, selling of assets, etc.
