I bought linkedin a couple of months ago at like 108 or so... I'm debating whether or not to sell half or all my stock... needless to say the wife is thrilled that I finally did some investing right :)
Since it's a cash deal, you'll miss out on ~$4 share, and since you bought in Feb/March, you'll end up paying your normal tax rate in capital gains. My guess is they approve this deal before Feb/March so no clear advantage holding for that reason.
Perhaps someone else could chime in as well?
