If a return of 24 - 50% pa is made consistently for a prolonged period of 5 years or more, then I presume it is the yardstick for consideration.
In my experience, I have made a return of 70% in a month and I have kept struggling to retain it for rest of the year. Finally ended with 24% profit for the whole year. It is not called consistency. Had I made 2% per month, then it could have been called so.
When it comes to consistency, a quarterly return is the right time period to consider especially for swing or day traders. There are good chances of bouncing back in one month even if other two months are negative. Even if we can make 6 to 10% on quarterly basis, that is good.
Even if we consider, yearly domestic expenses plugged at Rs.3,60,000, we need a capital of atleast Rs.20 lakhs to breakeven and survive here provided we make atleast 6% on quarterly basis. IMO, if any trader makes 6% per quarter on a capital of Rs.20 lakhs or above really needs a pat and he is consistent and successful trader.
Less capital makes you to do heroic trades to earn big and ultimately loose your capital and your financial survival becomes a question.
