Friday was a down day for the stock market, which responded to the latest economic news on the jobs front. The monthly release from the Labor Department said that nonfarm payrolls rose by 156,000 during September, which was slightly less than most economists had expected to see. Some might have seen that as a positive indicator that monetary policy from the Federal Reserve might remain looser for longer, but a rise in average wages and hours worked led many to believe that the Fed is on track to hike rates as early as December.
