Markets after the midterms

11 minutes ago

The recent US midterm elections have once again reminded investors that politics and markets are often closely watched companions. While election outcomes can influence policy direction and investor sentiment, history suggests that markets tend to focus more on economic fundamentals, corporate earnings, and interest rates over the longer term.


One of the key takeaways from the election was the Democrats' success in retaining control of the Senate. This outcome reduces the likelihood of significant legislative gridlock on certain policy matters and may provide greater continuity for existing administration priorities. Areas such as infrastructure spending, clean energy initiatives, healthcare policy, and technology regulation are likely to remain in focus.


Increased Scrutiny on Data and Technology Companies

The election result may also signal ongoing regulatory attention towards large technology and data-driven companies. Policymakers from both major parties have expressed concerns around data privacy, competition, the development of artificial intelligence, and the growing influence of some of the world's largest technology platforms. As AI becomes increasingly important to economic growth and national security, technology companies are likely to face greater political and regulatory scrutiny regardless of which party is in power.


Recent events at Nvidia highlight how quickly governance and oversight issues can become a focus for investors. Shares in the AI chipmaker fell following news that its board had launched an independent investigation involving CEO Jensen Huang, underscoring the market's sensitivity to leadership, governance, and national security considerations at strategically important companies. While the long-term growth prospects for leading technology businesses remain compelling, investors should recognise that regulatory, governance, and key-person risks can all influence valuations and market sentiment.


Importantly, these issues rarely alter the fundamental drivers of innovation and digital adoption overnight. For long-term investors, the most important factors remain a company's competitive position, financial strength, ability to innovate, and quality of management. Political developments and corporate headlines may create short-term volatility, but enduring investment outcomes are generally driven by business fundamentals rather than news cycles.


How Have Markets Historically Performed After Midterm Elections?

While elections often generate uncertainty beforehand, history suggests that markets have generally responded positively once the results are known and uncertainty begins to fade.

Since World War II, US equities have typically delivered above-average returns following midterm elections. Although past performance is never a guarantee of future results, the historical data is noteworthy:

  • US sharemarkets have often experienced positive returns in the week and month following midterm elections as investor uncertainty declines.

  • The 12 months following midterm elections have historically been among the strongest periods of the US presidential cycle.

  • On average, the S&P 500 has generated double-digit returns in the year following a midterm election.

  • Market gains after midterms have been recorded under both Democratic and Republican administrations, suggesting that the removal of uncertainty may be more important than the specific political outcome.


Several factors may contribute to this trend. By the time midterm elections occur, investors often have a clearer understanding of the political landscape for the remainder of the presidential term. This increased certainty can help improve business confidence, support capital investment decisions, and reduce market volatility.


Keeping Perspective

While election outcomes attract significant media attention, long-term investment success is rarely determined by politics alone. Economic growth, inflation, company earnings, innovation, and interest rates continue to play a far greater role in driving market returns over time.

For investors, the key lesson remains unchanged: maintaining a diversified portfolio and staying focused on long-term objectives is generally more effective than attempting to position portfolios around short-term political events.


As the post-election environment unfolds, we will continue to monitor developments and assess any implications for investment markets. However, history suggests that disciplined, long-term investing remains the most reliable path to achieving financial goals, regardless of which party occupies the political spotlight.
