I think it depends on the stock. Some of the better REITS barely dip while turds like WWE spike up and back. My favorite was New Flyer which I found a $6.06 and still pays out almost 9 cents a share monthly.
I've had a few washes but for the most part, I ride it out for the year. That's why I hold thru the ex dividend date and hold for all four quarterly dividends on certain stocks. I'm hoping the overall gain will allow me to ride long term.
Stocks like American Capital Agency or Invesco Mortgage Capital are potentially worth the hold. I know any dip will recover at some point in the year.
Honestly, I cannot remember the last time I just played a dividend and bailed on the ex-dividend date.
