Actually very simple. Go to Investor Village and look at the MLP board. There is a long discussion about institutional selling that is going on right now. Most hedge funds lock in clients except for several windows. One of those is the first 15 days of December. Retail clients do not sell short positions as most do not know what it is. Retail clients also do not put 50K units blocks up for sale and when that block sells offer more at .20 lower! If you saw the chart for many of the MLPs over the last week you can actually see the action and how the prices moved. EPD, MWE, WPZ, APL and lately EPB all relentlessly hammered.
Intrinsic value is all that is important, not market fluctuations. I learned that in 1970. Just find an EPD and hang onto it like Dan Duncan did. Do you think Warren Buffett dumped his Berkshire in the market drops he went through? The CNBC mentality is causing a lot of people to leave a lot of money on the table.
