The first half of 2026 delivered strong market gains despite persistent inflation, changing interest-rate expectations and geopolitical uncertainty. As investors look ahead, the focus is beginning to shift from what has already happened to what may influence markets during the remainder of the year.
While global markets may have room to move higher, investors should also be prepared for periods of increased volatility. Lighter late-summer trading, sudden news developments and uncertainty surrounding the 2026 midterm elections could all contribute to larger market movements.
At a Glance:
- Market volatility may increase during the second half of 2026, particularly during the late-summer months and as the midterm elections approach.
- Corporate earnings remain an important long-term market driver, even when short-term headlines influence investor sentiment.
- Diversification, rebalancing and a long-term perspective can help investors keep their portfolios aligned with their goals during unsettled markets.
Watch the 2026 Market Outlook
In the accompanying video, Pete Nicholson, Chief Fiduciary Officer at First National Wealth Management, discusses the factors that may shape the markets during the remainder of 2026 and why investors should be prepared for additional volatility.
Why Market Volatility Could Increase
Volatility is a normal part of investing, but certain market conditions can make price movements more pronounced.
Late-summer trading volume is often lighter than during other times of the year. With fewer market participants actively buying and selling, markets can become more sensitive to unexpected economic reports, geopolitical developments and other breaking news.
The 2026 midterm elections may also create uncertainty. Markets often respond not only to election results, but also to changing expectations surrounding taxes, regulation, government spending and economic policy.
These factors do not necessarily point to a negative market outlook. They do, however, suggest that investors should be prepared for periods when markets react quickly to new information.
Markets Look Forward, Not Backward
Financial markets are forward-looking. While news coverage often focuses on events that have already occurred, investors are generally evaluating what economic conditions and corporate performance may look like in the months and years ahead.
This helps explain why markets can continue moving higher even during periods of uncertainty.
The first half of 2026 included inflation concerns, geopolitical conflict, fluctuating oil prices and changes in interest-rate expectations. Despite those pressures, the broader market remained resilient, supported by strong corporate earnings, a relatively durable economic backdrop and continued capital investment within the artificial intelligence space.

Why Corporate Earnings Still Matter
Short-term market movements may be influenced by headlines, political developments and economic reports. Over longer periods, however, corporate earnings remain one of the most important drivers of stock market performance.
Strong earnings can support investor confidence and stock valuations. Weaker-than-expected results, declining profit margins or cautious corporate forecasts can create pressure.
As the second half of 2026 unfolds, investors will be watching whether companies can continue delivering earnings growth in an environment shaped by higher borrowing costs, inflation and changing consumer behavior.
Volatility Does Not Always Require Action
Periods of market uncertainty often create pressure to make changes.
Investors may feel compelled to sell after a decline, move into investments that have recently performed well or react to political and economic headlines. These decisions can move a portfolio away from the long-term strategy it was designed to support.
Volatility alone does not necessarily mean a portfolio needs to be changed.
A more useful question is whether the portfolio still reflects the investor’s:
- Long-term financial goals
- Investment time horizon
- Income and liquidity needs
- Comfort with market fluctuations
- Broader financial and estate-planning priorities
When those factors remain unchanged, staying disciplined may be more appropriate than reacting to short-term market movements.
The Role of Diversification
Diversification involves spreading investments across different asset classes, industries, geographic regions or market segments.
The goal is not to eliminate risk or prevent losses. Instead, diversification is intended to reduce the effect that weakness in one area may have on an overall portfolio.
This can be particularly important when market performance is concentrated within a relatively small number of companies or sectors.
A diversified portfolio may provide exposure to investments that respond differently to changing economic conditions. The appropriate mix will depend on each investor’s goals, time horizon, financial circumstances and tolerance for risk.
When Rebalancing May Be Appropriate
Market gains and losses can gradually cause a portfolio to move away from its intended allocation.
For example, if one asset class performs particularly well, it may eventually account for a larger share of the portfolio than originally planned. That can increase the portfolio’s exposure to risk, even when the change resulted from positive performance.
Rebalancing is the process of reviewing a portfolio and making adjustments to bring it back toward its intended allocation.
This does not mean responding to every market movement. Rebalancing should be thoughtful and based on the investor’s broader financial plan, strategy and individual circumstances.
Regular portfolio reviews can help determine whether market performance or changes in an investor’s life have created a need for adjustment.
Staying Focused on Long-Term Goals
The second half of 2026 will likely bring a mix of opportunities and challenges. Corporate earnings, inflation, interest rates, geopolitical events and election-related uncertainty may all influence market sentiment.
No one can predict each short-term market movement with certainty. Investors can, however, prepare for volatility by maintaining a strategy that reflects their long-term goals.
A diversified portfolio, periodic rebalancing and a disciplined perspective can help investors remain focused when markets become unsettled.
Frequently Asked Questions
Why might market volatility increase during the second half of 2026?
Lighter late-summer trading, geopolitical developments, economic reports and uncertainty surrounding the midterm elections could make markets more sensitive to new information.
Should investors change their portfolios when markets become volatile?
Not necessarily. Portfolio decisions should be based on long-term goals, time horizon, financial needs and tolerance for risk rather than volatility alone.
What is portfolio rebalancing?
Rebalancing is the process of adjusting investments to bring a portfolio back toward its intended asset allocation after market movements cause it to drift.
Does diversification prevent investment losses?
No. Diversification does not guarantee a profit or prevent losses. It is intended to spread investment exposure so that a portfolio is not overly dependent on one holding, sector or asset category.
Why are corporate earnings important?
Corporate earnings help investors evaluate the financial health and future prospects of publicly traded companies. Over time, the ability of companies to generate and grow earnings is an important driver of market performance.
Prepare for the Remainder of 2026
Investors do not need to predict every market movement to prepare for uncertainty.
A thoughtful portfolio should be designed to withstand periods of volatility while remaining aligned with long-term goals and aspirations.
