Rethink S&P 500: Excluding SpaceX Costs Investors

The S&P 500’s current index methodology, particularly its backward-looking GAAP net income rule, is facing scrutiny. Experts suggest this approach might be excluding major, innovative companies like SpaceX, potentially hindering the index’s true market representation.

S&P 500’s Flawed Foundation

Sam Ro, CFA, argues for a re-evaluation, noting the S&P 500’s design acts more like an active momentum strategy with hidden costs. This backward-looking profitability requirement often sidelines large, unprofitable firms that trade on future expectations rather than immediate earnings.

• Exclusion of Innovators: Companies like SpaceX, despite their significant market presence and future potential, are currently excluded due to unprofitability.
• CFA Institute Research: A paper by Rob Arnott and Lillian Wu, “The Active Side of Indexing,” highlights how alternative methods could offer better returns.
• Alternative Methodologies: Simple market cap or five-year average market cap inclusion could bypass subjective judgments and profitability issues.

Navigating Macro Crosscurrents

While the S&P 500 debates its future, the broader economic landscape presents mixed signals:

• Inflation: Consumer price inflation rose to 4.2% year-over-year in May, with core CPI at 2.9%, though expectations are cooling marginally.
• Labor Market: Sentiment worsened with increased perceived job loss probability, yet private job growth remains stable and unemployment claims low.
• Retail & Spending: Chicago Fed data showed declining retail sales in May, contrasting with Bank of America’s robust 5.1% year-over-year card spending growth.
• Housing Market: Home sales increased by 3.2% in May, with median prices rising for the 35th consecutive month, alongside ticking higher mortgage rates.
• GDP Outlook: Near-term GDP growth estimates from the Atlanta Fed’s GDPNow model track positively at 3.3% for Q2.

The Long-Term View

Despite the crosscurrents, a bullish long-term earnings outlook persists, driven by healthy consumer and business balance sheets. Economic growth rates are normalizing, with hard economic data holding up better than soft sentiment indicators.

The stock market may outperform the economy due to positive operating leverage from cost adjustments and AI investments. However, investors must remain vigilant about risks like political uncertainty, geopolitical turmoil, and energy price volatility, maintaining a long-term investment perspective.
