If you like it, especially in stocks, a small management fee of 1 or 2% and no incentive is a great way for a young trader to develope a very lucrative carreer.
because, you put together 5 or 10 200K accounts now, and over time that becomes 20 million under management, and so that is a cool 300k per year on top of your own personal account.

But a long term conservative approach grows as the clients income grows, and if you do well, you will soon be managing their family's and friends accounts.
