doubt is , is it a selling at profit good idea or to hold it for long time is good idea.
Perennial questions, it seems that when I sell a share thinking that it has exhausted its run, it invariably goes up at least in the short term
and vice versa. Still I am not bad in my account.
As to a particular share, none can be said to be a 'true blue chip', when times are bad, everyone falls! Very difficult to predict why yesterdays blue chips didn't fare well today (e.g. Colpal).
So the rules of the game are
read and re-read books, trial and error, not to take any risk (the loss of which you cannot absorb), take at least partial profits bringing down original cost and lastly enjoy the game, the prizes are much more rewarding, the longer you play.
