Jack Hough points to other important factors that affect the Dow Jones Industrial Averages and the S&P 500 Index. The quality of earnings, the relationship between wages and corporate earnings, and macroeconomic factors, all affect the level of the indexes. The historical average of wages relative to earnings would leave shares at 24 times earnings says Hough. This would mean a further decline of 40%. As U.S. companies earn more of these profits overseas compared to the past, they could sustain a higher level of earnings relative to wages says Hough, but this may not be the level at which they are today. In Hough's view the earnings numbers are made to look better than they actually are, which should be taken into account. He does not mention macroeconomic factors which add to the volatility, and policy decisions which create higher levels of uncertainty affecting decisions on consumption and investment in the economy.
