Explanation:

The unemployment rate is a macroeconomic indicator that explains the current situation of the economy. It is a share of the labour force that is jobless. If the unemployment rate is higher than unanticipated the overall prices generally go down that leads to a decrease in the stock prices. A high unemployment rate leads to a decrease in overall purchasing power.
