I am also stil holding PEM which I bought at around $3+, but IMO this stock is really undervalued.
Have a look at some net asset per share comparisons here :
Stock NetAsset/SP Current Sp ratio
---------------------------------------------
MRE $ 1.50 $ 6.46 4.3
GBG $ 0.185 $ 0.745 4.02
MCR $ 1.039 $ 3.20 3.07
ZFX $ 7.82 $10.88 1.39
CBH $ 0.22 $ 0.40 1.81
PEM $ 1.14 $ 1.35 1.18
IMO be patient !, its strong asset backing will support the SP.
