Gross Domestic Product

The total monetary value of all goods and services produced within a country over a period.

Gross Domestic Product (GDP)

GDP is the broadest measure of economic activity and the primary gauge of an economy's health.

Components

GDP = C + I + G + (X − M)

  • C (Consumer spending): ~70% of U.S. GDP
  • I (Business investment): Equipment, structures, inventories
  • G (Government spending): Federal, state, and local
  • X − M (Net exports): Exports minus imports

GDP growth rates

  • Above 3%: Strong expansion
  • 2–3%: Healthy growth
  • 0–2%: Slow growth
  • Negative for 2+ quarters: Commonly called a recession

Nominal vs. real GDP

  • Nominal GDP: Includes inflation effects
  • Real GDP: Adjusted for inflation—the more meaningful measure for comparisons

Why investors care

  • GDP growth drives corporate earnings growth
  • Slowing GDP may foreshadow lower stock returns
  • GDP reports can move markets significantly on release day
  • The Fed watches GDP to guide monetary policy decisions
