GDP and Economic Growth Indicators

Gross Domestic Product (GDP) is the broadest measure of economic activity. Understanding GDP and its components helps you anticipate market-moving trends before they become obvious.

What is GDP

Definition

• The total monetary value of all goods and services produced within a country in a specific period
• Measured quarterly (annualized) and annually
• The single most comprehensive measure of economic health

GDP Formula

• C = Consumer spending (approximately 70% of US GDP)
• I = Business investment (equipment, buildings, inventory)
• G = Government spending
• X - M = Net exports (exports minus imports)

Types of GDP

• Nominal GDP: Not adjusted for inflation, can be misleading
• Real GDP: Adjusted for inflation, the meaningful number
• GDP Per Capita: GDP divided by population, measures standard of living
• GDP Growth Rate: Percentage change from previous period

Leading Economic Indicators

These indicators move BEFORE the overall economy, giving you advance warning.

PMI (Purchasing Managers Index)

• Survey of purchasing managers in manufacturing and services
• Above 50 = expansion, below 50 = contraction
• Released monthly, one of the earliest data points
• ISM Manufacturing PMI for US is the gold standard
• Flash PMI (preliminary) releases move markets

Initial Jobless Claims

• Weekly count of new unemployment filings
• Very timely (released every Thursday for the prior week)
• Rising claims = weakening labor market
• Four-week moving average reduces noise
• One of the best real-time recession indicators

Building Permits and Housing Starts

• Construction is interest rate sensitive
• Leading indicator of economic activity and employment
• Decline in permits often precedes economic slowdowns
• Construction employs millions and has huge multiplier effects

Yield Curve

• The relationship between short-term and long-term interest rates
• Normal: Long-term rates higher than short-term
• Inverted: Short-term rates higher than long-term (recession warning)
• Every US recession since 1970 has been preceded by an inverted yield curve
• Watch the 2-year vs 10-year Treasury spread

Consumer Confidence

• University of Michigan Sentiment Index
• Conference Board Consumer Confidence
• Consumers who feel confident spend more
• Steep declines often precede economic contractions

Coincident Indicators

These move WITH the economy, confirming current conditions.

Non-Farm Payrolls (NFP)

• Monthly count of US jobs added or lost
• Released the first Friday of each month
• Among the most market-moving data releases
• Unemployment rate released simultaneously
• Revisions to previous months can be significant

Retail Sales

• Monthly measure of consumer spending
• US consumer spending drives 70% of GDP
• Core retail sales exclude autos (volatile)
• Important for gauging economic momentum

Lagging Indicators

CPI/Inflation

• Confirms price pressures after they have built
• Important for central bank policy but not for forecasting growth

Corporate Earnings

• Reflect economic conditions from the prior quarter
• Important for stock valuations but backward-looking

Trading Around GDP Data

Before the Release

• GDP estimates are updated as component data is released
• Atlanta Fed GDPNow model provides real-time GDP tracking
• Markets are forward-looking and often already priced in expectations

The Release

• Three estimates: Advance, Second, Third (released over 3 months)
• Advance estimate moves markets most
• Compare actual vs consensus expectations
• Focus on the GDP components that surprised

Key Takeaways

1. Leading indicators (PMI, yield curve, jobless claims) forecast economic direction
2. NFP is the single most important monthly economic release
3. Consumer spending drives 70% of US GDP
4. An inverted yield curve has preceded every modern US recession
5. GDP data is backward-looking - lead indicators are more tradeable
