Why Investors Care
With consumer spending a large part of the economy, market players continually monitor spending patterns. Retail sales are a measure of consumer well-being. Both the Federal Statistical Office and the Bundesbank publish retail trade data. Until recently, there were vast differences between them, primarily because they each used a different seasonal adjustment program. This difference ended when the Statistical Office began using the U.S. Census Arima X12 methodology as well as their Berlin method. Another difference is that the Federal Statistical Office data are generally for total retail sales while the Bundesbank data features sales excluding autos and petrol stations or excluding only autos. The data here are for total retail sales.
The pattern in consumer spending is often the foremost influence on stock and bond markets. For stocks, strong economic growth translates to healthy corporate profits and higher stock prices. For bonds, the focus is whether economic growth goes overboard and leads to inflation. Ideally, the economy walks that fine line between strong growth and excessive (inflationary) growth.
Retail sales not only give you a sense of the big picture, but also the trends among different types of retailers. Perhaps auto sales are especially strong or apparel sales are showing exceptional weakness. These trends from the retail sales data can help you spot specific investment opportunities, without having to wait for a company's quarterly or annual report.
