Election results sits at the center of this dementia and brain health question.

Yes, the recent election results are already reshaping investment portfolios across the board, with energy, materials, and consumer staples leading the rotation away from technology stocks that dominated 2025. If you have investments in your retirement accounts or brokerage holdings, you’ve likely noticed shifts in which sectors are performing—energy is up 21% year-to-date, materials up 17%, and industrials up 12%, a reversal from the tech-heavy gains of the previous year. This isn’t random market movement; it’s a direct response to policy expectations following the election, as investors anticipate tax cuts, increased defense spending, and a different regulatory environment than the previous administration. This article explores how election results are driving these portfolio changes, what to expect as 2026 unfolds, and how this might affect your own investment strategy, whether you’re managing a modest retirement account or a more substantial portfolio.

The shift is significant because it affects how wealth is distributed across different investment types. Someone heavily weighted toward tech stocks faces portfolio headwinds, while those with energy or industrial holdings have seen unexpected gains. The pattern also follows historical precedent—markets have a documented pattern of performing strongly in the months following midterm elections, which suggests the current volatility and sector rotation may be temporary positioning for stronger performance ahead. Understanding what’s driving these changes helps you make decisions that align with your financial goals rather than reacting emotionally to daily market headlines.

Why Are Election Results Triggering Immediate Portfolio Changes?

Election results influence investor behavior through two main mechanisms: policy expectations and sector preferences based on those policies. When a particular party wins control of congress, investors immediately begin repositioning money toward sectors that will likely benefit from that party’s policy agenda. In the current case, Republican control of Congress has shifted investor focus toward defense and industrials, since defense spending is expected to increase—this is why defense contractors and companies that supply defense industries are seeing strength. Similarly, anticipated tax cuts are attracting money into sectors that have historically benefited from lower corporate taxes and regulatory relief. The energy sector’s 21% year-to-date gain reflects expectations of less stringent environmental regulation and potential policy support for fossil fuel industries. Materials stocks are up 17% partly because of expected industrial spending and infrastructure projects.

Consumer staples, typically seen as defensive holdings, are up 15%—a sign that some investors are taking a cautious stance and rotating into less volatile sectors. This isn’t everyone moving in lockstep; different investors have different interpretations of what policies will help their specific holdings. However, the aggregate effect of millions of individual decisions to reposition creates these measurable sector shifts that show up in quarterly returns. One important caveat: sector rotation can be violent and sudden. Just as money rushes into energy today, if political circumstances change or if energy prices drop unexpectedly, money can exit just as quickly. Those gains seen year-to-date assume the policy environment remains stable. If Congress passes fewer tax cuts than expected or if the economy weakens, the flows can reverse, and investors who chased these gains near their peaks can suffer losses.

Why Are Election Results Triggering Immediate Portfolio Changes?

Historical Election Year Market Performance and What It Means for 2026

History offers a clear pattern for investor confidence: the one-year period following midterm elections has returned an average of 15.4% since 1950—nearly double the return of non-election years. This is worth highlighting because current market anxiety often focuses on the short-term volatility that occurs during election season. Data shows that the period immediately after elections (November through April of the following year) averages +14% S&P 500 gains, suggesting we’re entering what has historically been the strongest part of the election cycle. For 2026, we’re in this post-election strength period, which explains why despite initial volatility, many forecasters expect the year to produce positive overall returns. However, the path to these returns is not smooth. The S&P 500 has experienced an average intra-year drawdown of 18% during midterm election years. This means during the worst stretch of the year—even in years that end up positive—investors have typically seen their portfolios decline by roughly one-fifth at some point.

If you’re the type of investor who panics and sells when your portfolio is down 18%, you’ll likely lock in losses and miss the recovery. If you can tolerate volatility and remain invested, history suggests you’re rewarded handsomely. The distinction matters enormously for personal financial outcomes. The caveat here is that past performance doesn’t guarantee future results. Each election cycle occurs in a different economic environment. 2026 is not identical to previous election years—current inflation, interest rates, and global conditions are unique. While the historical patterns are encouraging, they’re not a promise. Additionally, these are average returns; some election years underperformed while others exceeded the average significantly.

Tax Policy Changes and the Windfall Coming to Individual Investors

Beyond sector rotation, the election results triggered expectations of substantial tax policy changes that will have direct effects on investor portfolios and cash flow. Tax cut stimulus is projected at $51 billion per quarter in the first half of 2026, with individual taxpayers receiving roughly $160 billion in deductions and credits for the 2026 tax year. Tax refunds are expected to increase 44% year-over-year compared to 2025. For many households, this means either larger tax refunds next spring or lower withholding throughout the year, putting more money into paychecks immediately. This matters for portfolio changes because people with sudden cash flow improvements—either from larger refunds or higher take-home pay—tend to invest that money. If this year your tax refund is 44% larger than last year’s, you have more capital to deploy into your investment accounts. Retirees and older investors on fixed incomes may see tax liability decline, leaving more of their Social Security and pension income in their pockets rather than going to taxes.

This extra cash supports the consumer spending that keeps the economy strong, which in turn supports continued stock market gains. For investors specifically, it means more dry powder to buy stocks during any market dips that occur. One important limitation: these tax benefits assume Congress actually passes tax legislation as currently proposed. Tax bills can be delayed, modified, or blocked entirely. Additionally, tax refunds are money that was already yours—the tax system is simply returning it to you. While a larger refund feels good psychologically and improves cash flow, it’s not actually extra income; it’s money you over-paid to the government throughout the year. Some investors overly celebrate refunds and spend them on consumption rather than saving or investing, which means the tax benefit doesn’t compound into long-term wealth.

Tax Policy Changes and the Windfall Coming to Individual Investors

Defense and Industrial Spending as Portfolio Drivers

The policy environment favoring increased defense spending is one of the most concrete expectations driving current portfolio changes, and it represents opportunity alongside risk. Defense contractors, industrial companies that supply components to defense, and companies that benefit from military infrastructure spending are all positioned to see revenue and profit growth if defense budgets increase as anticipated. Morgan Stanley and other analysts have highlighted this sector as likely to benefit from policy emphasis on U.S. military and economic influence. Industrials more broadly benefit because defense spending drives industrial production—the machinery, materials, and manufacturing capacity required to meet defense needs. The industrial sector’s 12% year-to-date gain reflects positioning for these expected benefits. Companies like Lockheed Martin, Raytheon, and others in the defense industry have seen notable gains.

But beyond the obvious defense contractors, suppliers of materials, transportation, and logistics also benefit when there’s high government spending on defense. If you own a diversified index fund or mutual fund with broad industrial exposure, you’re getting some of this benefit automatically without having to pick individual defense stocks. If you own only technology stocks, you’re missing this rotation entirely. However, there’s a real risk here worth considering: defense spending programs take time to ramp up, and profits aren’t guaranteed. A company that gets awarded a large defense contract still needs to execute on it, manage costs, and navigate government contracting regulations. Additionally, geopolitical circumstances could change unexpectedly—a peace agreement, trade deal, or shift in international tensions could reduce the perceived need for increased defense spending. History also shows that defense stocks can underperform if inflation accelerates or if the Fed raises interest rates in response to government spending increases. Those considering overweighting defense sectors should do so thoughtfully rather than chasing recent returns.

Market Volatility Warnings and What to Watch

The comfortable historical pattern of positive one-year returns following elections shouldn’t lull investors into ignoring real risks present in the current environment. Volatility is elevated, and the 18% average intra-year drawdown during election years is a meaningful risk that can shake the confidence of nervous investors. If your portfolio drops 18% from its peak, you’re seeing $18,000 in losses for every $100,000 invested—a real and measurable setback. Some investors respond to this volatility by shifting to bonds or cash, which locks in losses and leaves them holding lower-returning assets when the market recovers. Critical factors to watch in 2026 include inflation, interest rates, and earnings growth. If inflation re-accelerates due to increased government spending from tax cuts, the Federal Reserve might need to keep interest rates higher for longer than markets currently expect. Higher interest rates hurt technology stocks (which dominated 2025) and also reduce the value of future corporate earnings.

Additionally, the economy could slow—sometimes increased government spending during strong times overheats the economy and triggers recession. If 2026 ends in economic slowdown, the positive election-year return pattern could be broken. Corporate earnings growth is another critical metric; the returns of the past month have been based on expectations of future earnings growth, not current results. The specific warning for older investors or those near retirement: don’t let short-term volatility panic you into poor long-term decisions. Some retirees see their portfolio down 10% in February and immediately move everything to bonds, locking in losses. Historically, staying invested through election-year volatility has paid off, but it requires discipline and faith in the historical pattern. If you know you’ll panic and make poor decisions when your portfolio drops 15%, the time to address that is now—before volatility hits—by either diversifying differently or working with a financial advisor who can keep you focused on your long-term plan.

The Long-Term Perspective: Why Election Year Noise Can Mislead

The daily business cable news coverage of election impacts, sector rotations, and political developments can create an illusion that short-term timing is crucial. In reality, expert analysis consistently shows that markets perform well regardless of which party controls Congress. Capital Group research demonstrates that historical market performance has been positive across administrations and party control of Congress, suggesting that the fundamental drivers of long-term returns—innovation, productivity, demographic growth, and business profit—matter far more than which politicians are in charge.

For older investors managing portfolios during dementia or cognitive changes, this long-term perspective is especially valuable. If you’re hiring someone to manage your accounts or working with a family member to oversee your investments, the most important conversation is about your long-term goals and risk tolerance, not about optimizing for this quarter’s sector rotation. The noise of election impacts fades over years and decades. The compounding power of staying invested in diversified assets through multiple election cycles—regardless of the outcomes—has historically been the path to wealth building.

What 2026 Means for Retirement Planning and Portfolio Adjustments

As 2026 unfolds, the combination of tax refunds, anticipated government spending, and defense sector strength creates a specific moment for investors to assess whether their portfolios are properly positioned for their goals. If you’ve been holding 100% bonds or cash out of fear, the potential for strong post-election returns might justify adding equity exposure. If you’re overweighted in technology because that worked in 2025, the current rotation might signal a need to diversify.

The key is making adjustments thoughtfully based on your situation, not chasing recent performance. For those managing investments during cognitive challenges or illness, this is the moment to ensure documentation and decision-making authority are clear. If you have significant assets and you’re experiencing cognitive changes—whether related to dementia or normal aging—having conversations with family or a professional advisor about investment strategy, risk tolerance, and decision-making processes now, while you’re sharp, prevents costly mistakes later when decisions might be made by less informed people. The election results have triggered market movement and will create decisions to be made throughout 2026; you want to face those decisions from a position of clarity and preparation.

Conclusion

Election results are absolutely driving measurable changes across investment portfolios this quarter, with clear sector rotations, policy expectations, and tax implications reshaping where investor money flows. The historical pattern suggests we’re entering a period of typically strong market performance, with one-year post-election returns averaging 15.4% since 1950. However, that return comes with the reality of an 18% average intra-year drawdown during election years—meaning patience and discipline are required to see the promised returns.

The practical takeaway is neither to ignore the election impacts nor to overreact to them. Focus your investment strategy on long-term goals, maintain diversification across sectors rather than chasing the best recent performers, and use any tax refund windfalls or extra cash from the anticipated tax cuts productively by investing in your future. If you’re managing a family member’s finances due to cognitive changes, this is a good time to ensure investment strategy and decision-making authority are documented and discussed clearly. The markets will likely reward patience in 2026, but only for those disciplined enough to stay the course through inevitable volatility.
