Why did the stock market fall when the economy is doing well?
The answer is that one reflects the past and the other anticipates the future.
Last Friday’s advance estimate from the Bureau of Economic Analysis showed the U.S. economy grew 3.5 percent during the third quarter of 2018. Harriet Torry of The Wall Street Journal reported:
“The economy powered ahead in the third quarter, driven by robust consumer and government spending, though Friday’s report included warning signs that the business sector faces turbulence that could hold back the expansion in the months ahead.”
Third quarter’s economic growth was slower than economic growth during the second quarter and stronger than economic growth during the first quarter of 2018.
