IMP will drop as long as platinum is dropping. Commodities are dropping because of fears of global recession. Such fears will continue until AIG has been stabilised - and that is the best-case scenario.
The government gave them a loan (at a very high interest rate compared to what the Americans are used to) to give them time to sell their assets. AIG is failing in an orderly manner rather than a disorderly manner. I really can't understand why the Dow went up yesterday (with the biggest gainers being financials) and I'm too baffled to offer an opinion on what will happen in the future.
