NeuroMetrix (NURO)--Thin Float, High SIR

NeuroMetrix (NURO) has a been a crap investment for the GDT::Portfolio. The little company seems to be making progress, but it's been a slow go. On 02014.06.10 I noticed that NURO's SIR (short interest ratio) is as 12.8. ~31% of NURO is closely held leaving an approximate float of 5.2 million shares. NURO closed yesterday (02014.06.09) at $1.89. 52-week range: $1.47 - $4.25. The temptation to add some NURO to the GDT::Portfolio is strong, but I'll sell some NURO if it hits $Pi ($3.14).
