This claim shows that there is uncertainty that is driving the market's behavior. During the shutdown, the economic reports had been delayed, which also affected many investors. Finally, once the government reopened, those reports were expected to resume, which would show the growth or rise of unemployment. As a result that markets have declined before the data has been released.
This situation highlights just how sensitive markets are when there is no information being provided. The investors cannot see the routine data, so they must assume the worst. Due to the reopening, a shift in the uncertainty has now shifted to increased anxiety. Bad news has influenced a lot of the markets more than good news reports. This reflects the psychological aspect in the financial markets.
