High volatility persists in U.S. stock trading. If on Monday the market saw panic selling and forecasts of a new collapse on the back of skyrocketing yields on U.S. debt, on Tuesday we saw exactly the opposite movement with forecasts of further growth based on future strong corporate reporting. Both participants are partly right and this situation is seen quite often during this period of the year called the September Dip, the point of September lows before the Christmas rally of the last three months. Statistically, the market goes into a bullish phase at this point, but debt uncertainty and a difficult upcoming budget fight in the Senate could make major adjustments to this statistic.
