Produced by the Bureau of Economic Analysis, Gross Domestic Product (GDP) data is ranked as one of the three most influential economic measures that affect U.S. financial markets. GDP is the value of the goods and services produced by the nation’s economy less the value of the goods and services used up in production. GDP is also equal to the sum of personal consumption expenditures, gross private domestic investment, net exports of goods and services, and government consumption expenditures and gross investment.
