I wouldn't worry about it, it's a relatively small MLP, bound to be more volatile than the market. Maybe it got ahead of itself a little when it ran up, now there's an over-reaction on the downside. MWE boomed over $60, used that for an offering, immediately rebounded back over $60 and then took a dump itself. Why? May as well ask why a ball bounces a certain way, just the random walk. Quantum security dynamics, they just can't stay still.
