March 2026 Market Update: Diversification at Work in a Shifting Market

February was a month that highlighted the importance of diversification and disciplined portfolio management.

Large U.S. stocks, as measured by the S&P 500 Index, declined approximately 0.75% for the month. The Dow Jones Industrial Average posted a slight gain. Bonds, broadly measured, rose about 1%. Meanwhile, certain international markets delivered notably stronger returns, with some areas rising approximately 6%.

As always, individual portfolio results vary depending on allocation, tax considerations, and specific holdings. However, the dispersion in asset class performance this month underscores why diversified portfolios may behave differently than a single headline index.

Let’s take a closer look.

A Market Rotation Away from Technology

A continuing theme in recent months has been a rotation away from large-cap technology stocks. Some market participants have referred to this shift as the “Anything But Tech” trade.

Because the S&P 500 Index is heavily weighted toward large technology companies, weakness in that sector can meaningfully impact index performance. When leadership narrows or rotates, index-level returns may not reflect the performance of other asset classes or regions.

In diversified portfolios that include exposure beyond U.S. large-cap equities, performance drivers can differ significantly from the S&P 500 in any given month.

As Doug noted in this month’s update, in some diversified portfolios, international exposure and bonds helped offset weakness in U.S. large-cap stocks

While diversification cannot guarantee gains or prevent losses, it can reduce reliance on any single sector, region, or asset class.

The Role of International and Bonds

International equities were a notable contributor to market performance in February. After an extended period of U.S. market leadership in prior years, global markets have at times shown signs of relative strength.

International investing does involve additional risks, including currency fluctuations, geopolitical events, and varying accounting standards. However, global exposure can provide differentiated return streams when leadership shifts.

Similarly, bonds contributed positively during the month. Fixed income investments carry their own risks, including interest rate risk and credit risk, but they may provide stability or income depending on market conditions.

When asset classes respond differently to economic and market developments, diversified portfolios may experience less volatility than more concentrated strategies. That said, all investing involves risk, and returns will vary over time.

Tax Season and Scam Awareness

March also coincides with tax season, a time when financial scams tend to increase.

Fraudsters often attempt to exploit urgency, sending emails, texts, or placing phone calls requesting immediate action or confidential information. These communications may claim to be from government agencies or financial institutions.

A common red flag is urgency—demands for immediate payment, bank account information, or personal data.

If you receive suspicious communication:

  • Do not click links in unsolicited emails or texts.
  • Do not provide personal or financial information.
  • Independently verify phone numbers or websites before responding.
  • Consult trusted sources like your CPA or advisor if you are unsure.

When something feels urgent or threatening, pause and verify. Taking a few extra minutes can help protect your financial information.
