Fall Market Swoon, Followed By An End-Of-Year Boom? | Mark Newton @Fundstrat_Direct

Mark Newton argues that markets generally favor political gridlock because it limits major policy changes and provides continuity, while a narrow Democratic House victory would likely have limited economic impact. He also says bipartisan agreement is needed for difficult deficit reforms such as reducing spending on Medicare and Medicaid or changing Social Security, making major fiscal action politically challenging.

The United States may need substantial grid investment to support continued data-center expansion, potentially combining the country's strength in compute with China's advantage in producing electricity. At the same time, rising memory prices could increase the cost of iPhones and other products and eventually prompt government scrutiny over monopoly or unfair-pricing concerns.

Newton says investors should respect the prevailing AI trend until observable evidence shows a meaningful slowdown or reversal, rather than relying on valuation anxiety alone. However, he has heard more reports of compute costs rising faster than productivity gains than of transformative returns, creating a risk that weak earnings gains could undermine the estimates supporting current AI optimism.

The post-World War II reduction in US debt-to-GDP from about 110% to 40% over roughly three decades offers a historical template, but Newton emphasizes that the comparison is limited because the United States was then the world's manufacturing hub and benefited from foreign reconstruction demand. Today, robust profits and a relatively healthy economy are offsetting debt concerns, although roughly $40 trillion of debt and a deficit above $2 trillion could become more consequential if conditions deteriorate.

Newton views the recent crude-oil increase primarily as a supply shock rather than a rapid change in demand, while recent inflation expectations, PCE, GDP, and CPI data have generally supported the Federal Reserve's decision not to act. He says rate hikes typically take 12 to 18 months to affect the economy and argues that Fed communication must balance clearer guidance against the market confusion and bond volatility that can result from too much or too little commentary.

US growth has lost momentum, moving from 3.8% in Q2 2025 and 4.4% in Q3 to 0.5% in Q4, then recovering to 2.1% in Q1 2026 and 1.5% in Q2 2026 without an outright contraction. Long-term interest rates remain a key risk channel for housing and the broader economy, although current high-yield markets and other indicators do not yet show significant stress; mortgage rates around 6.7% are a headwind whose impact varies substantially by location.
