The trading action on NOK and ALU reminds me of INFN as it started to descend to the 4s (this was around mid 2012, if memory serves me right), this, even though it was at the inflection point in sales of their then new 100G system. Frankly, there was no reason why it dropped so low.  Now INFN's stock is north of $21  It reminds me that the market can and is often wrong about the long term prospects/potential of a company.  And we know the market can distort valuations on both the high and low side, it happens all the time.

I am going to hold on to my shares, the trading action may be poor over the short term, but the eventual gain is IMO a 100% return.  I have felt this way for some time, so a long term investment it is for me, i.e. 3 to 4 years or until my investment thesis no longer holds true.
