Sell EPD? Yes, sure, sell your winners and let your losers ride. Did your broker offer any reasons why selling EPD for KYN is a wise thing? You must remember that brokers would be more aptly named, SALESMEN. That's how they make their living echoing the company's recs which are all based on how much money that make for ML.
I see there was a KYN offering about that time and I suspect ML had a lot of KYN to unload.
Of course we'd all be interested in knowing if you did the deed and are satisfied with the result.
