Must be a warrant but can find no information. Anybody know?
You want to know why? Its b/c as I stated in an earlier post the IACIW are merely Expedia warrants that became IACI warrants in the acquisition.
There's no such thing as iaciw. There is iaciz, trading at 41.73. I'm holding some, this is an option to buy iaci stocks at a futute date with a strike price. Make sure you know what you are doing before buying warrants.
One more thing...it's not an even exchange ratio, 1 iaciz = X iaci (X > 1).
