Quick thoughts on the stock market and the economy
from Dean Baker
We are seeing the usual hysteria over the sharp drop in the markets in Asia, Europe, and perhaps the U.S. (Wall Street seems to be rallying as I write.) There are a few items worth noting as we enjoy the panic.
First and most importantly, the stock market is not the economy. The stock market has fluctuations all the time that have nothing to do with the real economy. The most famous was the 1987 crash which did not correspond to any real world bad event that anyone could identify.
Even over longer periods there is no direct correlation between the stock market and GDP. In the decade of the 1970s the stock market lost more than 40 percent of its value in real terms, in the decade of the 1980s it more than doubled. GDP growth averaged 3.3 percent from 1980 to 1990 compared to 3.2 percent from 1970 to 1980.
Apart from its erratic movements, the stock market is not even in principle supposed to be a measure of economic activity. It is supposed to represent the present value of future profits. This means that if people are expecting the economy to slowdown, but also expect a big shift in income from wages to profits, then we should expect to see the market rise. So there is no sense in treating the stock market as a gauge of economic activity, it isn’t.
