Except for that huge buy last October, Accumulation/Distribution has been pretty flat. It has been ticking upward since the start of Feb, but not much.
My buys tend to coincide with W%R below -80 and when the shares are in "distribution" mode. For now, MESA's been stuck at the W%R -80 or more since the beginning of December. There's about 2.2% short interest currently on the stock. Price/Book value is under 0.40 right now. BETA is huge at 2.76.
