Statistical physics predicts stock market gloom
A statistical physics model is predicting that the US stock market recovery suggested by recent rises will only last until spring next year, before tumbling yet further. Physicists at the University of California in Los Angeles claim to have identified an "anti-bubble" in the Standard and Poor's 500 stock market index. Their model also describes a similar anti-bubble in the Japanese Nikkei index in the early 1990s, which preceded a decade of decline. (New Scientist)
