Nope, the reason for the drop in all MLPs was due to a Dow Jones decision to exclude them from a DJTotal Market index starting Dec 21. All funds following this index dumped them, but they have since rebounded nicely. Too bad I didn't see that news earlier -- could have sold during the day on that Friday and repurchased on the 21st.
Don't let it bother you one bit, if you'd like to buy, do so now. Always buy on the dips. Some of the stockholders have had this for many years and will tell you to sit back and enjoy the dividends.. Merry Christmas to all and happy trading
