The day after the Ex-date on hi dividend earners like LNCO tend to have these big collapses the day after... then we wait another week to get back to where we were, unless something bad market wise happens!
The only comment I would add to that, is that oil, and NG have been dropping a little bit.
(NG about 4.12, oil 102 this AM).
.70 is a lot bigger then the divi.
Never the less, I agree overall with you.
