Hi Ramya,
Mr.Deepak's response might have given you basic understanding about shares.For beginers like you Share Trading may be dangerous and world over it's proved that who invests for long term in shares can gain.
It is because of this kind of chase for hot money,people have been trading and lots of them have burnt fingers.Look at the following example and let me know your response.
You,me,Mr.Deepak and 2 more friends have started a stationery shop in a decent locality where schools,colleges and offices are more (with Rs.25,30,35,40,50k each and the shop named as MATRIX opened in a glittering ceremony).Now say after 3months,if one of our partner(share holder) comes and asks for Rs.50k,what will be your response.Hope if my guess is correct,there are 3 options:One-Ask him politely to wait as the business has just started and yet to recover what we have invested;Two-One of us buy his stake-if any one of us are that rich!;Three-Sell some stationery even at loss and recover and pay his amount less losses incurred.....
If Mr.Deepak comes and asks after 3years for Rs.10k,we all may be very glad to give what he has demanded/requested.....
If I come and ask after 5years for Rs.15k,we all may be very glad to give what I have demanded/requested.....
If you comes and ask after 10years for Rs.50k,we all may be very glad to give what you have demanded/requested and also you might have received some decent income as profits during these 10years too.....
If many of us in the world understand this basic thing in Stock Markets like WARREN BUFFET,we might become the richest of the world.....Anybody who would not buy this basic thought process can show one stock trader who is the richest in the world.......
