Monthly Market Memo – February 2026: U.S.-Israel Strike on Iran, Broadening Markets & AI Disruption

March 10, 2026

By Case Eichenberger, CIMA® | Chief Investment Officer, RetirePath Advisors Published: March 2026

February delivered a clear message to investors: diversification is working.* While the S&P 500 retreated modestly — down roughly three-quarters of one percent for the month — virtually every other major asset class posted meaningful gains. For clients at RetirePath Advisors who hold diversified portfolios spanning U.S. small and mid-cap stocks, international equities, and fixed income, February was an encouraging continuation of a trend building since the start of the year.

February Performance at a Glance

Small and mid-cap stocks led the way in February, gaining approximately 2.5%, while international stocks surged more than 5% for the month alone. Bonds also had a notably strong February, rising roughly 1.5% — providing exactly the kind of ballast we'd hope to see during a period of equity volatility. Cash returned about 0.25%.

Year-to-date through the end of February, the picture is even more striking. Small and mid-cap stocks are up 7–12%, and international stocks have climbed over 11% in just two months. For many years, these categories sat in the shadow of the S&P 500 and U.S. growth stocks. That is changing in a meaningful way in 2026.

A Note on the U.S.-Israel Strike on Iran

To end the month of February, a joint U.S.-Israel strike on Iran's nuclear infrastructure destroyed several sites and removed the country's leader. Markets opened down roughly 1% on the news before recovering to finish essentially flat — a resilient response.

History offers useful perspective here. Looking back at geopolitical conflicts and wars from 1928 to the present, markets have consistently experienced short-term volatility around such events before resuming their longer-term upward trajectory. What ultimately drives stock prices over time — GDP growth, corporate earnings, and consumer spending — has continued to improve through past conflicts, and the current earnings picture, both domestically and internationally, remains constructive. Historically, geopolitical-driven pullbacks may have represented entry points rather than permanent impairment to portfolios.

The Great Rotation: Yesterday's Leaders Are Today's Laggards

One of the most important themes defining 2026 is a rotation in market leadership. Last year, growth stocks surged over 22% and the S&P 500 gained roughly 18%, while small caps, mid-caps, and value stocks lagged significantly. So far in 2026, that script has flipped. Growth stocks are flat to slightly negative. Value stocks are outperforming. Small and mid-cap companies have already exceeded their full-year 2025 returns in just two months.

This kind of broadening leadership is a healthy sign. It is a hallmark of a maturing bull market — one that is expanding its base rather than becoming increasingly dependent on a narrow group of mega-cap names.

The AI Spending Surge and Its Impact on the S&P 500

A significant undercurrent weighing on the S&P 500 this year has been the dramatic ramp-up in AI infrastructure spending among the largest technology companies — the so-called "hyperscalers." Google, Microsoft, Meta, Amazon, and others are collectively on pace to spend somewhere between $500 billion and $700 billion on AI data centers and infrastructure in the years ahead — a staggering increase from prior expectations in the $70–100 billion range.

The consequence for investors is reduced free cash flow — the lifeblood of these companies' valuations. Amazon is down roughly 8% year-to-date, Meta and Microsoft are off around 20%, and Oracle — which takes on more debt than its peers to fund these buildouts — is down nearly 37% over the last six months (all data as of 2/25/2026). The S&P 500, while still up approximately 8.5% over the past six months, has seen its near-term momentum dampened as markets hold these companies accountable for returns on their AI investments.

Software Stocks: Disruption Beneath the Surface

Underneath the headline index numbers, software companies are facing their own AI reckoning. Household names like Salesforce and Adobe have come under pressure as the market questions whether AI will compress their profit margins — or render some of their core offerings obsolete entirely. While the NASDAQ has stayed relatively flat to start the year, software stocks as a sector have rolled over noticeably.

One piece of data offers a reassuring counterpoint: software job postings on platforms like Indeed are up over 12% year-over-year, even as overall job postings remain flat or slightly negative. The market for skilled software talent remains robust — a signal that companies are still investing in human expertise even as they navigate the AI transition.

Fed Policy and What Comes Next

As we look toward mid-2026, Federal Reserve Chair Jerome Powell is expected to depart, with Kevin Warsh — the president's stated nominee — set to take the helm. Markets have priced in approximately two rate cuts this year, likely beginning around the June or July meeting and continuing toward year-end. This gradual easing path, combined with resilient corporate earnings and broadening market leadership, has historically been a supportive backdrop for equities.

Bottom Line

February reinforced the value of staying diversified. The areas of your portfolio that may have felt like dead weight in 2024 and 2025 — international stocks, small-caps, value — are now the engines of return. The bull market is maturing and broadening, and the data supports that assessment. As always, discipline and a long-term perspective remain your greatest advantages. Please don't hesitate to reach out with any questions about how these developments affect your personal financial plan.
