Tech back on track, Fed keeps its foot on the brake.

Our view on the markets and investment strategy in the September 2026 Market Compass.

As we enter September - historically the weakest month for the S&P 500 in midterm election years - selectivity and disciplined positioning remain essential.

Tech back on track as AI cycle powers ahead

Following July's correction, technology stocks rebounded strongly in August, led by the semiconductor sector. Nvidia surged +10.0% after reporting revenue that doubled year on year to USD 96.2 billion, while guidance of USD 108 billion for the current quarter once again exceeded elevated expectations. The rebound confirms our prior assessment: the correction did not represent a fundamental shift away from the AI investment theme. The S&P 500 gained +2.6% and the Nasdaq 100 advanced +4.2%, while European markets lagged with the EuroStoxx 50 up just +1.0% and the Swiss SPI declining -0.3%, weighed down by Nestle (-2.7%), Novartis (-2.6%) and Roche (-0.2%).

Fed Chair Warsh keeps the door open for further rate hikes

At the Jackson Hole symposium, Fed Chair Kevin Warsh delivered a clearly hawkish message. Despite more encouraging inflation data and early signs of labour market cooling, Warsh stressed that inflation remained well above the 2% target and that underlying price pressures had not improved sufficiently. The market implied probability of a September rate increase rose from around 35% before the speech to almost 60% afterwards. The monetary policy outlook remains firmly dependent on incoming data.

Middle East conflict keeps oil markets on edge

Diplomatic efforts between Iran and Oman over a temporary shipping corridor through the Strait of Hormuz failed to produce a lasting agreement. Tensions escalated further when US forces struck Iranian missile positions on Larak Island, prompting retaliatory attacks on US bases in Jordan. Brent crude rose back above USD 90 per barrel, and shipping through the Strait remained significantly restricted. The conflict continues to represent a meaningful risk factor for global inflation and central bank flexibility.

Bessent intervenes in the bond market

US Treasury Secretary Scott Bessent attracted considerable attention with a surprise announcement that the Treasury would at least double its purchases of long-dated government bonds to curb the sharp rise in yields. The move initially pushed yields lower and weakened the US dollar, supporting the gold price. However, the market reaction proved short lived as investors remain sceptical that technical measures can sustainably offset concerns surrounding high government deficits and persistent inflation.

Midterm election seasonality - a historical perspective

In midterm election years, September has historically been the weakest month for the S&P 500, with an average decline of around 1.5%. However, this period of weakness has often marked the starting point for a strong recovery, with October and November recording average gains of around 2.4% and 2.2%, respectively. We monitor these seasonal patterns closely but never consider them in isolation.

How we are positioned

We remain constructive on equities over the medium term and maintain our overweight position, though we would not chase markets following the recent recovery. The greatest risk to our outlook comes less from the corporate side and more from a potential sustained breakout in long-term US yields. Our tactical stance: Cash 2/5, Fixed Income 3/5 with caution on duration risk, Equities 4/5 with a firm preference for the US, and Alternative Investments 4/5 with gold as our highest conviction holding.
