Why wait? The price if anything will spike if you believe the sale/buyback will be larger than the last sales and even if it isn't bigger AIG is showing progress.
In the past the share price of the common shares has gone down as we approached a sale but this time seems to be showing more strength. The warrants usually hold up much better during a sale/buyback so I would not wait. Remember you could buy warrants for well under 11 bucks in July. Next week we hit $14 Cheers
