I try to stay calm, however, although not that experienced and seasoned I´m smart enough IMO to see they are somewhat fooling us ... at least I have experienced that behavior in several previous "investments" (which mostly turned out as not that good) ...
That´s my problem here: NTEK firstly (whole 2013) showed a completely new game for me: reliable, trustworthy, credible - and that constantly many times confirmed through their (sometimes even over-)delivered promises ... with such an experience (sweetened by an awesome pps-development) the whole year 2014 with this stock you feel as little catastrophe because they changed to the opposite in many (former positive) regards, going along with a horrible pps-declining (which you naturally and consequently estimate as safe proof or result of their lost quality) ... I blatantly get reminded of the numerous dangling carots otherwhere ... NTEK is practicizing this smelling tactic masterly ... and there´s nothing what could change my mind, although I may tend to exaggerate (what I to be honest hope inwardly, LOL) ...
It´s the contrast between 2013 and 2014 what makes me deeply concerned and doubting ...
