Agree with your assessment that INFN is now a show me company.  I plan to hold it, even though I think it will take at least two quarters to regain some altitude, and that assumes there are no more roaches in the house, which we both agree may be too optimistic.

So why would I hold it?  I believe the company will get its ducks in a row and execute on the TM product.  Clearly Fallon and company have fallen short in regards to selling the TM product. I would expect that fixing this issue would be priority one for Fallon. Management may have had a lapse with regards to the lost customer account, but I believe that the company's overall portfolio makes the story still very relevant and any blemishes are fixable. 

Even with this fiasco, the management team is quite capable; they have successfully become the leading Optical Equipment outfit and competed effectively against entrenched and much bigger players.  The stock has fallen this much mainly because the level of Institutional ownership had reached 75%, so it is not surprising that it has fallen this hard.
