when one buys a security he must always consider it's value ....that a fundamental part of investment be it a (min day week year etc..) he holds it for and then consider..."Is this security more valuable than the moment I bought it?" some securities are priced as the market determines (What will someone pay me right now if i should sell into the market at present?"
Some however hold a security for it's future value knowing the price the market is paying currently is way too low for such a security....such persons recognizes an inherent value that the market is not presently reflecting and is willing to wait(a few mins ..days..weeks..years etc) until it does... when markets pressures on price starts to show up what that security is being willing to be paid for(either lower or higher) then those who determines that's what his or hers security is valued is good for them ...he or she then cashes out collecting either a gain or loss (Time Valued)
Ntek price currently is reflecting pressure (volume confirms and gap up) that it's going higher what each one must determines ...Is this the value of my share worth?... if it is..... then sell selll and get on your happy way.
