The consumption data for the Christmas and growth of GDP for the fourth quarter have injected vigor to the US stock market. We notice that the negative correlation between the US stock market and dollar exchange rate has begun not very obvious since the financial crisis. During the first 11 months of this year, the dollar rate went against the stock market in 70% of trading days. The rebound of US dollars as of December is partly due to the investors’ worry about the sovereignty bonds of the European and the emerging markets. Nevertheless, the more important thing is that the trend of revival for the American economy has been further confirmed and the US dollar value has been increased. Under the background, the US market does not always slide with the hike of US dollars, as the dollars went against the stock market in 50% of the trading days of December. Therefore the trend of US stock market is more bolstered by the economy. The Christmas consumption and the growth of GDP for the fourth quarter will remain the key factor recently. We forecast that amid the increasing expectation of economic recovery and growingly stable job market, the holiday consumption may beat the pessimistic expectation and the GDP growth for the fourth quarter will hit a new year high. The labor market may see a turning point from squeeze to stability and the US stock market is forecast to continue the hike in the first quarter of 2010.
