How the Iran war has reshaped equity performance

Bar chart comparing year-to-date performance of 11 equity sectors across two periods: from the start of the year to the onset of the conflict, and from the conflict’s start to March 20. Energy is the only sector with positive returns since the start of the conflict, gaining 5.9%.Sources: Bloomberg and Wells Fargo Investment Institute. Daily data is from December 31, 2025 – March 20, 2026. Pre-conflict measures from December 31, 2025 – February 27, 2026. Outbreak of Iran War March 2 – March 20. The returns are from Feb 27 - March 20. An index is unmanaged and not available for direct investment. Past performance is no guarantee of future results. Excerpted from Investment Strategy report (March 30).

Dispersion has increased sharply across equity sectors since the start of the war

Since the Iran War began in late February, equity market performance has shifted away from the cyclical, broad based leadership that characterized the start of the year. Sector and regional returns suggest that the conflict did not result in a flight to quality assets such as gold, U.S. Treasuries or defensive equity sectors but instead accelerated rotation within equities, resulting in higher dispersion across geographies, asset classes, and sectors.

The chart above shows this increase in dispersion at the equity sector level (represented by S&P 500 index sectors) since the start of the Iran war. For example, Energy has been a significant outperformer while defensive sectors such as Utilities, Consumer Staples, and Health Care have, surprisingly, underperformed.

What it may mean for investors

We prefer diversification and rebalancing for portfolios with long-term risk and return objectives. We see the current market volatility and rotation as an opportunity to consider exposure to U.S. Large Cap Equities and to rebalance from the Energy sector toward Financials. We continue to favor Industrials and Utilities and believe the Information Technology sector is attractive, with forward price earnings multiples selling near historical averages.

Risk Considerations

Diversification cannot eliminate the risk of fluctuating prices and uncertain returns.

Each asset class has its own risk and return characteristics. The level of risk associated with a particular investment or asset class generally correlates with the level of return the investment or asset class might achieve. Stock markets, especially foreign markets, are volatile. Stock values may fluctuate in response to general economic and market conditions, the prospects of individual companies, and industry sectors.

Sector investing can be more volatile than investments that are broadly diversified over numerous sectors of the economy and will increase a portfolio’s vulnerability to any single economic, political, or regulatory development affecting the sector. This can result in greater price volatility. The Energy sector may be adversely affected by changes in worldwide energy prices, exploration, production spending, government regulation, and changes in exchange rates, depletion of natural resources, and risks that arise from extreme weather conditions. Investing in the Financial services companies will subject an investment to adverse economic or regulatory occurrences affecting the sector. There is increased risk investing in the Industrials sector. The industries within the sector can be significantly affected by general market and economic conditions, competition, technological innovation, legislation and government regulations, among other things, all of which can significantly affect a portfolio’s performance. Risks associated with the Technology sector include increased competition from domestic and international companies, unexpected changes in demand, regulatory actions, technical problems with key products, and the departure of key members of management. Technology and Internet-related stocks, especially smaller, less-seasoned companies, tend to be more volatile than the overall market. Utilities are sensitive to changes in interest rates, and the securities within the sector can be volatile and may underperform in a slow economy.
