A big part of this is seasonal. MLP's have a low period every year. Not to be complacent because there are real worries this year. But do some research before you let yourself be scared out of your investments at a low price.
As I recall, I made money the last time I bought KMP around $77. (I sold in the upper $80's, if I remember right.) Stocks go up and down. If you buy a little when it's down and sell a little when it's up, you improve your basis and your profits.
