If I knew that I would beat Warren Buffet hands down!



On the Indian bourses, there is an upper/lower circuit, some shares have 5%, some 10 and the others 20%. So you know you cannot get more than that.

When you buy a stock = (price prevailing at the time of transaction + brokerage) x number of shares = A

When you sell a stock = (price prevailing at the time of transaction + brokerage) x number of shares = B

Percentage return { If it is A more (loss), B more (gain)}

= (B-A)x100/A

You will get small gain if the raise is more than 2% on the next day. It is better to watch for longer time to get substantial gains. Hope this clarifies the issue.
