Simple math.
Do you know how much 12% compounded monthly for 10 years amounts to with a starting capital of say 1 lakh? In rupee terms, you wouldn't be able to fit all the digits on a regular calculator and need a exponential notation!
How many billion dollar retail traders have you seen again?
It's a common fallacy argument I have heard many times.
I said retail traders. These guys obviously have to live, don't they?
So, lets assume an experienced retail trader is trading with 10L trading capital. On average, he makes 10-15% a month. Obviously it comes in spurts and some months the returns are negative. But on average it comes to around 1L to 1.5L per month on 10L capital.
Basic expenses (varies a lot and depends on each individual). Lets say, 30-40K monthly expenses for living.
Some goes into savings (any experienced trader knows that he should keep a portion of his winnings in safer instruments.) Lets say bonds or FD's which is popular in India. So, around 30-40K goes in that.
Then there are taxes and other expenses. So, 20-30K goes into that.
If you remove all that the guy would probably be able to reinvest his trades to the tune of maybe 4-5%.
But anyone who has been in the market long enough knows that as the account size increases, it gets very difficult to trade without facing a lot of
slippage.
So a lot of traders usually have a comfort level and don't really want (nor need) to keep growing their trading account exponentially.
They account for inflation each year and grow their capital accordingly .
Yes, we don't see many billion dollar traders but then
you don't need a billion dollars.
If he can make even $100K (or maybe Rs 1-1.5L/m inflation adjusted to 2013 for example in Indian terms) he can live comfortably. There are many successful retail traders making 1L or some such figure.
I know the figure of 10-15% sounds preposterous to someone, but its very much possible in trading.
I am obviously not claiming I can make that much but I know of people who have been making that much year in and year out.
For me as a part time trader, 2-4%/m is enough and till now, I'm in the 2-4% mark.
