Nice trade. The ABBV.WI/ABT.WI ratio has increased to about 54/46. If these proportions hold when the real shares begin trading, I may sell some (or all) of the ABBV I get from my pre-existing ABT shares.
On the other hand, ABBV may have some good stuff to report at JPM, so I'll probably wait at least until then to sell.
