A "Fairly Highly Valued" (Stock) Market: The Fed Chair Opines but should anyone listen?

Key Concepts

• Market Valuation: Assessing whether stock prices are high or low relative to their underlying value.
• Irrational Exuberance: A term coined by Alan Greenspan to describe speculative market bubbles.
• Price-to-Earnings (P/E) Ratio: A valuation metric comparing a company's stock price to its earnings per share.
• Earnings Yield: The inverse of the P/E ratio, representing earnings per dollar of stock price.
• Treasury Bond Rate: The yield on government debt, used as a benchmark for risk-free returns.
• Intrinsic Value: The perceived underlying worth of an asset, often calculated based on future cash flows.
• Equity Risk Premium (ERP): The excess return an investor expects to receive for holding equities over a risk-free asset.
• Market Timing: Attempting to predict future market movements to buy low and sell high.
• Mean Reversion: The tendency for financial metrics to return to their historical averages over time.
• Mag 7: A group of seven large-cap technology companies (Apple, Nvidia, Microsoft, Alphabet, Amazon, Meta, Tesla) that have significantly influenced market performance.

Market Valuation and Central Banker Commentary

The discussion begins by referencing Jerome Powell's statement that stocks are "fairly highly valued," which is interpreted as a signal that they are "richly priced." This echoes Alan Greenspan's 1996 "irrational exuberance" comment during the dot-com boom. The speaker acknowledges that stocks are indeed richly priced by historical standards but questions the efficacy of acting on this observation through market timing.

2025 Market Performance Overview (US Equities)

Despite a news cycle filled with concerns about tariffs, inflation, and economic uncertainty, US equities have shown a "miraculous comeback" through September 30, 2025.

• S&P 500: Up approximately 13.7% in the first nine months.
• NASDAQ: Up 17.3% in the first nine months, having recovered from an earlier lag.

Sector Performance Divergence

The market performance has been highly divergent across sectors:

• Top Performing: Technology and Communication Services (driven by Alphabet and Meta, which are classified as communication services by S&P).
• Lagging Sectors: Consumer Staples, Healthcare, Real Estate, Energy, and Consumer Discretionary.
• Mid-Performing: Financials, Industrials, and Materials.

The Dominance of the "Mag 7"

The "Mag 7" (Apple, Nvidia, Microsoft, Alphabet, Amazon, Meta, Tesla) have significantly impacted market returns:

• 2023: Increased market cap by $5.1 trillion, accounting for nearly 55% of the total market cap increase for all US companies.
• 2024: Increased market cap by $5.6 trillion, representing almost 50% of the equity value increase.
• Q1 2025: Experienced a significant downturn, losing nearly $2.7 trillion in market cap and dropping to 26% of the overall market cap.
• Q2 & Q3 2025: Recovered strongly, collectively adding $2.8 trillion in market cap and accounting for 52% of the increase in all US equities, surpassing their starting percentage of the market.

Other US Equity Performance Dimensions

The speaker analyzed US equities based on other factors:

• Market Cap (Start of 2025): Small-cap companies outperformed large-cap companies, with the bottom half of US companies by market cap up 19.75% and the top 50% up 13.7%. This outperformance was largely driven by the third quarter.
• Price-to-Book (P/B) Ratio: Stocks with low P/B ratios (value stocks) showed a comeback in the first quarter, but high P/B stocks (growth stocks) regained dominance in the second and third quarters.
• Momentum (Percentage Price Change in 2024): Momentum stocks, which have dominated for the past decade, performed well again in 2025, particularly after a rough first quarter.

Global Equities Performance

• Global Equity Index (MSCI): Up 16.6% through September 30, 2025, outperforming the S&P 500. This is a reversal of the trend seen over the last 15 years.
• Regional Performance: Canada, China, EU, Eastern Europe, and Latin America outperformed the US. Much of this outperformance was attributed to a weakening US dollar.
• Worst Performing: India, down 3.15% in US dollar terms, potentially due to being an overpriced market entering 2025. Africa and the Middle East also underperformed.

Interest Rates and Default Spreads

Despite significant news events, US Treasury rates have shown minimal change throughout the year.

• Yield Curve: Has become slightly more upward sloping.
• Moody's Downgrade (May 16, 2025): Had little impact on interest rates. Default risk measures for the US (e.g., 5-year sovereign CDS) remained largely unchanged.
• Corporate Default Spreads: Also showed little movement, with the primary spike occurring in April after tariff shocks, which then dissipated.

Metrics for Market Overpricing

The speaker outlines four metrics to assess market overpricing, from least to most complete:

1. Stock Prices Alone: Simplistic view that high prices over a short period indicate overpricing.
2. Price-to-Earnings (P/E) Ratios: Compares stock prices to earnings. High P/E ratios relative to historical norms suggest overpricing.
   • Trailing P/E, Normalized P/E, and CAPE (Cyclically Adjusted P/E): All are at historically high levels not seen in at least 100 years of US stocks.
3. Earnings Yield vs. Treasury Bond Rate: Inverts the P/E ratio and compares it to the yield on US Treasuries.
   • Since 2022, T-bond rates have risen above 4%, making the earnings yield lower than the T-bond rate, which some consider an overpricing indicator. However, this metric has not been a reliable market timing tool.
4. Intrinsic Value (Present Value of Expected Cash Flows): The most complete metric, factoring in growth and reinvestment needs.
   • Implied Equity Risk Premium (ERP): Calculated by solving for the discount rate that equates expected cash flows to the current market level.
     • The ERP for the S&P 500 on October 1, 2025, was 4.01%, lower than the historical average (4.25% since 1960) and significantly lower than the 2015-2024 average. This suggests stocks are overpriced.
   • Intrinsic Value Calculation: Assuming a 4.25% historical ERP, the intrinsic value of the index is estimated to be 12.6% lower than its current level, indicating overvaluation.

Conclusion on Market Overpricing

Based on all metrics, US equities are considered "richly priced" by historical standards. If mean reversion to historical norms occurs, a correction is likely.

Choices When Stocks Are Overpriced

The speaker outlines five choices for investors when stocks are perceived as overpriced:

1. Do Nothing: Maintain current portfolio strategy.
2. Hold New Cash as Cash: Increase the cash balance in the portfolio without altering existing holdings.
3. Change Asset Allocation: Reduce equity exposure and increase bond or cash holdings.
4. Buy Protection: Use options (e.g., buying puts) or futures to hedge against potential declines. This is an expensive strategy.
5. Leverage a Bet on a Correction: Aggressively use options to profit from a market downturn.

The Futility of Market Timing

The speaker expresses skepticism about market timing, stating, "I am not a market timer."

• Requirements for Market Timing:
  • Pick a Pricing Metric: (e.g., P/E, CAPE, ERP).
  • Create an Action Rule: Specific triggers and actions for buying or selling.
  • Backtest with Specifics: Test the strategy with realistic assumptions, including taxes and transaction costs.
• Example with CAPE Ratio: A strategy based on a 25% threshold from the median CAPE ratio, adjusting equity allocation between 60/40, 80/20, and 40/60, resulted in a 0.04% annual loss compared to a buy-and-hold strategy over a century. More aggressive strategies also failed to deliver value.
• Reason for Not Market Timing: The speaker cannot find a way to make market timing consistently profitable, especially after accounting for transaction costs and taxes.

Personal Update and Conclusion

The speaker has been inactive on YouTube due to spending time with his 3-month-old to 5-month-old granddaughter. He is taking a sabbatical until May 2026 to care for her, finding it more fulfilling than market analysis. He concludes by reiterating that US equities are richly priced but emphasizes that market timing is a difficult game, and if successful, it can be rewarding. He encourages careful consideration of metrics and action plans for those who choose to attempt market timing.
