take a look at the below two link and see it 3 years backward in the graphs.
you can see that time and again those shares were manipulated.
HVA first manipulation was so massive that even though the floor limit is seen as Rs 9.90 or soo..
people cannot decide what its ceiling limit is...
it might go to 15 or 20 or maybe 40 or maybe a bit higher.. who knows..
that kind of guessing is what is keeping these kinds of heavily manipulated stocks alive and more the wait the more people scene that the next wave of manipulation is near. that is why these small jump occur...
once a real big fish manipulator gets its hand on these kind of shares on a good green day. he will push it real high... that is what most are expecting...
