It’s All About Earnings

Key Observations

The Federal Reserve cut its Fed Funds rate by 25 bps, the 10-year Treasury yield went up 10 bps, and the S&P 500 ended the month of October up over 2%. Let’s unpack those results. As we pointed out in our recent post-rate cut commentary: "A 4% 10-Year Treasury yield already prices in inflation ultimately getting to 2% … If inflation gets stuck around 3%, the 10-year yield could in fact drift up." If inflation does fall to 2% and the Fed is able to further reduce the Fed Funds rate, the 10-year Treasury yield is unlikely to fall farther, and it’s those longer-term yields that have a greater impact on stock market valuations. Moreover, a stable 10-year Treasury yield is unlikely to fuel future multiple expansion in price-to-earnings (P/E) ratios.

Another factor unlikely to drive multiple expansion is relative valuations. The narrative is ubiquitous—parts of the market look relatively cheap, but only compared to large-cap stocks. As the chart below demonstrates, the price-to-book (P/B) ratio of the S&P 500 stands at 5.6, while mid-cap and small-cap stocks are less than half that. Those discounts serve as many experts’ foundational argument for the “broadening” of the current market rally. But based on valuations alone, that foundation could seem a bit shaky.

The low relative valuations of mid-cap and small-cap stocks (and other asset classes) have been driven mostly by the S&P 500 getting more expensive rather than other assets getting cheaper. In reality, if you compare the 2015 and 2025 values for mid and small caps shown in the chart, they are trading today at roughly the same valuations as they were 10 years ago. Counting on multiple expansion to broaden the market rally could be a mistake.

If neither the Fed nor multiple expansion look bullish, what’s likely to drive near-term stock prices? It’s all about earnings.
