Bank of America's (BofA) Sell Side Indicator (SSI) suggests a potential 12% return for the S&P 500 over the next year. The SSI, which tracks Wall Street strategists' equity allocation recommendations, remained relatively unchanged in January. This contrarian signal typically performs best when strategists are most bearish, hinting at possible gains for investors.

The indicator currently sits at its most bullish level since March 2025, even though allocations are slightly below their January 2025 peak. BofA notes that the SSI is still far from a "Sell" signal, suggesting further upside potential. The S&P 500 saw a 1.5% increase in January, recovering from earlier geopolitical concerns.

Analysts at BofA express confidence in earnings resilience, with consensus forecasting 14% growth in 2026. Corporate sentiment is at a record high, and mentions of "weak demand" are decreasing. Guidance from companies has also been positive, with more companies issuing above-consensus earnings per share (EPS) forecasts.

This positive outlook from BofA's analysis provides a bullish sentiment in the market. Investors often watch indicators like the SSI for cues on market direction. The steady allocation by strategists indicates a belief in continued earnings strength, a key driver for stock market performance. This is good news for anyone holding S&P 500 index funds.
