After witnessing (and suffering) through a market run amok over the past 18 months or so, there is no logical answer to your question. Nevertheless, I'm leaning towards putting a portion of a matured C/D into this stock. I got quoted a renewal rate of ONE-HALF of ONE PERCENT for 9 months versus the still-putrid 2-1/2% that this C/D had been paying. My investment guy is high on M-K and I need the yield it is throwing-off.
Investors in MLP are not traders and if someone sells at the last minute the price will fall till there are enough buyer of shares. Intel also had a sell imbalance but it has lots of day traders to buy so it only dropped a bit on the sell inbalance.
Well, you know that everybody and his brother has been recommending MLP's for the past several months and they have had a nice ride upward. You can bet that all of those brokerage firms, fund managers, etc., etc. hyping these things decided to take a little money off the table. Trouble is when one starts, no one wants to be left holding the bag and they all try to sell at once. This whole category of investments was really taken to the cleaners in the last half hour of trading - essentially wiping out the gains of the last month or so.
