Hi Rockk,
The "charting thing" works with its own limitations. First, it works with "dead" data by which I mean it tries to extrapolate with data that is already "past" to predict what will happen in the future - whether in the next one hour, one day to one month. So it cannot take into account breaking news event or some company related story.
In case of Unitech, while other stocks have gone up, it has gone down thereby giving you a much better exit now (in case you are still holding).
This is because Unitech has been removed from MSCI India Index. There are privileged few who are privy to the news before you and I from "aam janata" so we are always the last to know. That is true everywhere, and cannot be completed eliminated. There is no such thing as "total transparency" - unfortunate fact of life.
