Fed rate cut and tech boom could lift markets but a choppy summer still looms, analyst warns

Despite a bullish technical picture, Truist's Keith Lerner cautions that US equity valuations are stretched, with the S&P 500 trading near 22x forward P/E, and seasonal volatility is expected in Q3 2025. While growth areas like tech and semiconductors remain favored, investors should temper expectations due to high valuations. Concurrently, a Barclays report indicates that geopolitical risks have historically had minimal observable impact on US equity returns over the past three decades, with industrials tending to outperform and energy lagging after shocks, suggesting these events are not a reason to abandon equities.

Analysis

The outlook for US equities in the second half of 2025 presents a juxtaposition of bullish technical signals against significant headwinds from stretched valuations and seasonal patterns. The S&P 500's forward P/E ratio is trading near 22x, the upper-end of its recent range, suggesting limited room for multiple expansion and prompting calls for investors to temper expectations. While the S&P 500 and Nasdaq have both posted gains of approximately 5% year-to-date, fueled by AI-driven momentum in stocks like Nvidia, the broader market has effectively traded sideways for seven months, indicating a narrow rally. This technical picture is supported by a softening Federal Reserve, steady economic data, and robust corporate earnings. Truist's investment office recommends maintaining a bias towards growth sectors like technology, semiconductors, and communication services, and is beginning to add international exposure. Separately, a Barclays report contextualizes geopolitical risk, noting that over the past three decades, such events have had minimal observable impact on US equity returns. The report highlights that industrials have tended to outperform and energy stocks have lagged following geopolitical shocks, contrary to some defensive assumptions.

Key Decisions for Investors

• Investors should maintain a constructive long-term view on equities but prepare for heightened volatility in the third quarter due to historical seasonality and elevated market valuations.
• Consider overweighting positions in favored growth areas, specifically technology, semiconductors, and communication services, and explore adding international equities for diversification.
• Exercise valuation discipline given the S&P 500's 22x forward P/E multiple, and conduct periodic portfolio reviews or 'gut checks' to manage risk in this environment.
• Avoid making reactive portfolio changes based on geopolitical risk spikes, as historical analysis suggests they do not significantly impact long-term US equity returns; instead, note the potential for sector-level rotation where industrials may outperform energy.
