The stock market is rallying. Commodities are on a tear. Yet the dollar is falling. Why?

There are several reasons for the drop in the dollar, but the most obvious and simple answer is that investors around the world are selling dollars and using the money to buy stocks and commodities, particularly oil and gold.

Last week India announced that it had bought 200 tons of gold from the International Monetary Fund (IMF.) At an average of say $1000.00 per ounce, the transaction amounted to about $7 trillion dollars. Chances are that India sold dollars from their sovereign fund to buy the gold.

It's almost October and the pundits are at again, predicting that the market should sell off again. Let's look at their reasoning.

• We have an ongoing deterioration in consumer debt.
• Joseph Stiglitz, Nobel Laureate, says that "the U.S. banking sector is now in worse shape than before the collapse of Lehman Brothers.
• Bank profitability is expected to come under pressure.
• The U.S. housing outlook is grim.

On Monday the Dow Jones Industrial Average dropped more than 200 points before closing a little better. No real reason for it. Pundits suggested the drop in commodity prices (oil and gold were down a little, not enough to comment on) were the reason for the dip, suggesting the economy may not be as robust nor inflation as big a problem as thought on the Friday before.

But here's the real scoop: the market has rallied well beyond a level where economic numbers justify.

The stock market, as measured by the Dow Jones Industrial Average, sharply rebounded from its low of 6440 in March of this year. Currently, as this is written, the notable index is hovering around 8400. That's an increase of 30%. Not bad for two months of trading. While the average is made up of only 30 stocks, those 30 stocks are some of the best. There are also some real losers, such as General Motors (NYSE: GM) and Citigroup (NYSE: C). But for the most part, the index contains the strongest industries with some of the strongest stocks. With that kind of recovery already in place, is it too late to buy stocks or is this just the start of a major rally?

Most CEOs expect things to get worse. Chief Executive Officers of major U.S. corporations were more pessimistic than three months ago about their business and the economy over the next six months, the Business Roundtable reported last Tuesday. The CEO confidence index fell to negative 5.0 in the first quarter from 16.8 in the fourth quarter. It was at 79.5 a year ago. The CEOs expect the economy to contract 1.9% in 2009. Over the next six months, about two-thirds of CEOs expect lower sales, lower capital spending and fewer jobs at their company. About a quarter expect sales to rise in the next six months, while less than 10% expect to increase hiring or capital spending.

Lately I've looked in vain for good news. I mean news that has some substance, that would make a real difference to an investor. I can't find any. In fact, I feel like a pinball, bouncing from one rubber post to another, each one accelerating the downward, inevitable path toward the black hole at the bottom of the board.

Is this science or science fiction? That thought came to mind when I read that traders who were exposed to more testosterone in the womb made six times more money than their low-testosterone-level peers on very volatile trading days. So if you want to breed a trader, expose him to lots of testosterone in the womb. How do you do that? Beats me.

To determine the traders' prenatal testosterone exposure, University of Minnesota researchers measured their "2D:4D ratio" which is the relative lengths of the index and ring fingers on the right hand. Those exposed to higher levels of testosterone in the womb tend to have relatively longer ring fingers.

Based on the 2D:4D measure, researchers who studied the traders' profits over a 20-month period between 2004 and 2007, found that those with the highest in-womb testosterone exposure in the womb earned six times more than those exposed to the least. They also tended to have the longest careers, surviving about three years longer on average.
