Hi Ramya,
Mr. Deepak's response might have given you a basic understanding of shares. For beginners like you, share trading may be dangerous, and worldwide, it's proven that those who invest for the long term in shares can gain.
It is because of this chase for hot money that people have been trading, and many of them have gotten burned fingers. Let's look at the following example and hear your response.
You, me, Mr. Deepak, and two more friends have started a stationery shop in a decent locality where schools, colleges, and offices are more prevalent (with Rs. 25k, 30k, 35k, 40k, 50k each, and the shop named as MATRIX opened in a glittering ceremony). Now, say after 3 months, if one of our partners (shareholders) comes and asks for Rs. 50k, what will be your response? I hope my guess is correct; there are three options: One - Ask him politely to wait as the business has just started and has yet to recover what we have invested; Two - One of us buys his stake if any one of us is that rich!; Three - Sell some stationery, even at a loss, to recover and pay his amount less the losses incurred.
If Mr. Deepak comes and asks after 3 years for Rs. 10k, we all may be very glad to give what he has demanded/requested.
If I come and ask after 5 years for Rs. 15k, we all may be very glad to give what I have demanded/requested.
If you come and ask after 10 years for Rs. 50k, we all may be very glad to give what you have demanded/requested, and you might have also received some decent income as profits during these 10 years too.
If many of us in the world understand this basic principle in stock markets like Warren Buffet, we might become the richest in the world. Anybody who does not buy into this basic thought process can show one stock trader who is the richest in the world.
