Just a reminder to "newbs" --- like today when everything opens "green" --- and then you see you have "A" stock that is red.... Why? What is wrong?
Remember to check to see if the stock is going "ex-dividend"... meaning that as of today it pays a dividend out so typically will trade down around par to the dividend payment (per share).
Kimberly Clark (KMB) is one of those today (I own so saw this "red" number on a green day) thus the reminder... and just to use this example because newbs might forget about checking this kind of thing. I always use the oddities in a market to look into "why" so that I'm not blindsided by some news that I might have missed.
