I would defintely add shares here. I read your blog, I think we would be very hard pressed to see low 40's again, let alone 30's. If your looking at buying future earnings, or even better buying the company as a whole why not buy now? 5% yield, huge ROE, excellent earnings growth, consistent dividend growth, room for expansion overseas, excellent management, share buy backs.
I dont see too much out of the above list to make the share price drop. Maybe currency fluctuation but how much do you see the dollar rising with this administration, a new health care build and record debt?
Buy at any price under 50 and hold this baby for 20 years.
