GDP (Gross Domestic Product)
The total value of all goods and services a country produces over a given period — the broadest gauge of an economy's size and growth pace.
In plain terms
GDP adds up the value of every good and service a country produced over a given period. It expresses the "overall size" of that country's economy in a single number.
Usually people look less at the size itself and more at "how fast it grew (the growth rate)." A positive GDP growth rate means the economy is expanding; a negative one means it is shrinking. Two straight quarters of negative growth are commonly regarded as a "recession."
What it tells you
GDP is the biggest-picture view of the economy's health. When the economy grows, corporate earnings, employment, and consumption generally tend to improve along with it.
Markets react less to GDP itself than to how it compares with expectations and to the trend. Whether growth is starting to roll over or picking up speed drives the mood.
Formula
GDP = the market value of all goods and services produced by a country over a period (usually a quarter or a year) GDP growth rate = the increase in GDP versus the prior quarter/prior year (economic growth rate)
What high or low means
Solid GDP growth is a positive for the economy, but in phases when inflation is running hot it can also be read as "growth so strong that it adds rate pressure." Like other indicators, it is interpreted both ways depending on the phase.
A situation where growth slows while inflation stays high (stagflation concerns) is a combination markets watch especially closely.
GDP is a lagging indicator that tallies up a quarter that has already passed. By the time it is released, the economy may already have moved into its next phase, so it has limits as a forward-looking gauge.
GDP is revised several times after its first release. It shows up more in the revisions and the trend than in the first number.
GDP is a macro indicator. This term is background knowledge for understanding market news. (※ Our screens cover the SEC-filed financials of individual companies.)
The saying "two consecutive quarters of negative real GDP means a recession" is widely repeated. In 2022, U.S. real GDP did in fact fall in both the first and second quarters (roughly -1.6% and -0.6% at an annual rate). By that "two-quarter rule," that period should already have been a recession.
But the body that officially dates U.S. recessions is the National Bureau of Economic Research (NBER), a private academic institution, and it judges a recession not by "two quarters of GDP" but by whether employment data, real income, industrial production, and consumption contracted broadly and persistently for several months or more. In 2022, hundreds of thousands of jobs were being added each month and the unemployment rate was around 3.5%, near a record low — meaning the economy had not cooled that much. So the NBER never declared that stretch a recession.
This episode shows that relying on a single GDP line, and on a convenient formula like the "two-quarter rule," can lead you to read the economy backwards. Even when GDP prints negative, the story changes if employment data and consumption are holding up over the same period. That is why, in gauging the economy, GDP fits the picture only when placed side by side with employment and consumption data.
