Can Mathematicians Beat the Markets?

Does it take a genius to beat the markets? Can a mathematician act quickly in the fast moving forex markets or better yet, pick out the best stocks to invest in? The markets are all about numbers, percentages, mathematical valuation modelling and so on... So it should make perfect logical sense that if a mathematician tried their hand at trading the markets, they would find it easy to succeed in consistently beating the markets. But is it true?
Have you heard this quote?
If all it took to beat the markets was a Ph.D. in mathematics, there'd be a hell of a lot of rich mathematicians out there.
The quote is from Bill Dries a commodity trading advisor from "Futures" published on August 1995.
Have you seen a rich mathematician? A glance through the Australian BRW rich list and all I see is a bunch of successful entrepreneurs - many with their own rags to riches stories. When I attend those trading seminars: those gurus all claim to be ex accountants, financial advisers, engineers or psychologists.
I don't doubt that there are no masterful mathematician traders out there, but mathematical intelligence is not a prerequisite to successful trading. To be able to trade the fast moving forex markets or simply the stock market takes guts. You need to be a risk taker yet calculating to manage that risk. Any trader that beats the market is a hard worker, actively reflecting on each and every trade, recording what went right and what went wrong. Great traders are passionate about their profession. Yes, mathematicians can beat the markets if they also possess these aforementioned qualities. Risk taker. Risk manager. Calculating. Passionate. Systematic. Reflective.
