Searching for "risk free profit" is like searching for the fountain of youth.
Leverage doesn't create alpha. It only enhances the returns (both good and bad)
The fountain of youth
does exist. When the body is fed the foods it was
designed to consume, and not the foods we humans eat
because we can due to agronomist technologies, it rejuvenates and heals itself. But this is very bad for the pharma business and the medical (butchers) profession, who treat sickness rather than cure it, so you won't be getting much pressure to go raw and cut out poisons.
The same can be said for the market. Look at the huge amount of infrastructure that exists outside of risk-taking. Look at an investment bank for example. The actual assets of the bank and its clients are directly managed by a small group of risk-takers/managers. Goldman Sachs has thousands of employees but less than 10% of them are the ones decided when, what and how much to buy and sell. The rest of them are middlemen, customer support, internal support, admin and middle upper exec management. This is just one bank. So when you look at the ecosystem of the market and you consider that over 90% of people involved in the market don't give a flying fuck about taking risk. They are investor relations, prime brokerage, financial journalist, blah blah... Why is buy and hold so prevalent? Because there wouldn't be a mutual or pension fund business without it. No huge brokerage business without it, etc. So
we the stuntmen on the ground in the thick of the shit can indeed find gems and pearls invisible to others because THEY DO NOT POSSESS THE EYES TO SEE.
Consider niche markets, like CDS trading, or even the new weather and climate derivatives that they are trying to get off the ground. How many people are actually executing trades in these markets? Not very many. There are probably alot of opportunities laying around waiting to make someone rich, but there aren't enough eyeballs fleshing them out.
To me, market efficiency is another theoretical concept that has distorted our general perception of how markets work. Markets are always in disequilibrium, for if they were totally efficient then participants wouldn't make or lose more than their proportionate share of the "pie". But we do everyday.
