The Core Idea

GDP — Gross Domestic Product — is the total market value of all final goods and services produced in a country in a given period. It's the economy's report card. When real GDP grows, unemployment typically falls and corporate earnings rise. When it contracts for two consecutive quarters, economists call it a recession — and equity markets usually price this in well before the official announcement.

How It Works

GDP = C + I + G + NX. C (Consumption) ~70% of US GDP. I (Investment — business capex, residential) ~18%. G (Government purchases) ~17%. NX (Net exports = Exports − Imports) −3% (trade deficit). Nominal GDP rises with both output AND inflation. Real GDP adjusts for inflation — the measure of actual productive output. Real GDP growth of 2–3% is healthy for a mature economy.

💡

Real-World Example: 2024 US GDP: C = $17.3T + I = $4.2T + G = $4.0T + NX = −$0.9T = $24.6 trillion. Real GDP grew ~2.8%. If real GDP were to contract for two consecutive quarters, the Fed would typically cut rates, corporate earnings would miss, and equity markets would price in lower multiples. The 2008 recession saw real GDP fall ~4% peak-to-trough — S&P 500 fell ~57%.
