The answer is NO.
There is no compelling reason to be long UPS other than perhaps day trading. If the TNT deal becomes a go you'll get some buying and lift in share price, but I believe savvy investors will use that as an opportunity to sell into.
Enjoy your very nice dividend. That's nice to have, better than cd's!
my guess is no! Not this year! It will take time to adjust tnt & world economy into stock increase to $80. How long depends on several factors! Good luck!
