There is an old Sufi tale about a mullah (Nasruddin) who was discovered by a passer-by searching in the dust outside his house. What was he looking for, the stranger enquired. A key, said the mullah. Where did he drop it? “In the house” replied the mullah. Then why was he looking in the dust outside? Because here he was in bright sunlight, whereas in the house it was dark and difficult to see.
It happens to us all the time. The solution to worthwhile problems is never out there in the open. The key to financial markets is elusive. It must be so - by definition. (c) Percival - The Way of the Dollar
The currencies are a pure zero-sum-game, the only one in fact. Zero-sum game - a situation in which one participant's gains result only from another
participant's equivalent losses. The net change in total wealth among
participants is zero; the wealth is just shifted from one to another. A stock market, however, is not a zero-sum game because wealth can be created in a stock market. In a pure zero-sum game there is no such thing as a crash. Taken as a whole, the players are never wiped out -in fact their wealth stays the same all the time. You win or lose only by playing better or worse. (c) Different sources
