I have some UL shares. I got these in late 2008, never traded them as I keep them as one of the dividend payers. Don't look at them much even. I have got a good gain on these, buying really low, but they have not been hot lately.
On Friday, it jumped 14%. So, that caught my attention, and I had to find out what happened. Good earning reports don't do this to a company like this (they cannot have surprises like biotechs or technology companies). The price at close was $48.53, still less than the $50 buyout offer. So, apparently investors were not sure that the deal would go through.
Now that the offer is canceled, the price will certainly drop back down. Oh well.
What is interesting is that shares of Kraft also jumped 11% on the news of the attempted takeover. Apparently, the failed merger was taken as a would-be good synergy.
