S&P 500 Between Valuations and Sector Rotation

S&P 500 Between Valuations and Sector Rotation

From the 2025 rally to the first challenges of 2026: earnings, multiples, and risk management

The overall index: how the S&P 500 has moved

The S&P 500 closed 2025 as a decidedly positive year, supported by earnings growth, easing inflation, and expectations of a less restrictive monetary policy. After a strong acceleration in the second half of the year, the index ended 2025 around 5,200 points, with an annual performance of approximately +22%.

The start of 2026 has been marked by greater caution: in the first weeks, the S&P 500 moved in a sideways range between 5,150 and 5,250 points, reflecting profit-taking on growth stocks and a partial rotation toward more defensive sectors. Volatility remains contained, but the market appears more selective compared with the linear rally of 2024–2025.

Valuations: P/E under scrutiny

One of the central themes for investors remains valuations:

• Trailing P/E (last 12 months): ~24x, above the historical average, only partly justified by earnings growth.
• Forward P/E (expected): ~21x, signaling that the market is pricing in further earnings expansion in 2026.
• Shiller P/E (CAPE): ~31x, well above the long-term average, indicating a structurally expensive market but not necessarily a bubble, thanks to lower real rates than in the past.

Overall, this suggests a market that is not cheap, where stock selection becomes crucial.

Final summary

The S&P 500 enters 2026 strengthened by the results of 2025, but with valuations that call for caution. Large technology stocks remain the engine of the index, while dispersion between winners and losers is increasing. In this scenario, the difference is made not only by stock selection, but above all by how risk is managed, making money management—also in automated form—a strategic element.
