Most traders take price swings personally. They feel very proud when they make money and love to talk about their profits. When a trade goes against them they feel like punished children and try to keep their losses secret. You can read traders’ emotions on their faces.

Many traders believe that the aim of a market analyst is to forecast future prices. The amateurs in most fields ask for forecasts, while professionals simply manage information and make decisions based on probabilities. Take medicine, for example. A patient is brought to an emergency room with a knife sticking out of his chest – and the anxious family members have only two questions: “Will he survive?” and “when can he go home?” They ask the doctor for a forecast.

But the doctor is not forecasting – he is taking care of problems as they emerge. His first job is to prevent the patient from dying from shock, and so he gives him pain-killers and starts an intravenous drip to replace lost blood. Then he removes the knife and sutures damaged organs. After that, he has to watch against infection. He monitors the trend of a patient’s health and takes measures to prevent complications. He is managing – not forecasting. When a family begs for a forecast, he may give it to them, but its practical value is low. (more…)

Is this the world’s most bearish man?

He is this man:

His name is Robert Prechter and he thinks the Dow will fall well below 1,000 over within the next six years. What’s more, he even speaks in Nostradamic verse:

Mr. Prechter is convinced that we have entered a market decline of staggering proportions — perhaps the biggest of the last 300 years.

In a series of phone conversations and e-mail exchanges last week, he said that no other forecaster was likely to accept his reasoning, which is based on his version of the Elliott Wave theory — a technical approach to market analysis that he embraces with evangelical fervor.

Originating in the writings of Ralph Nelson Elliott, an obscure accountant who found repetitive patterns, or “fractals,” in the stock market of the 1930s and ’40s, the theory suggests that an epic downswing is under way, Mr. Prechter said. But he argued that even skeptical investors should take his advice seriously.
