International vs. Domestic Funds: May 2026 Performance Review

May 2026 was a strong month for equity mutual funds, but the headline story was not domestic. Out of 609 equity mutual funds analysed, 556 delivered positive returns. Of those, 11 funds gave double-digit returns. Most of the top double-digit performers had global exposure, with Quant Teck Fund being the key domestic exception.

Mirae Asset Global X Artificial Intelligence & Technology ETF FoF topped the chart with a return of ~17.10%. Nippon India Taiwan Equity Fund came in second at ~14.75%, followed by Edelweiss US Technology Equity FOF at ~14.15%. Invesco India, Invesco Global Consumer Trends FoF delivered ~12.24%, and HSBC Global Emerging Markets Fund ~12.18%.

This was not a broad market rally. It was a concentrated outperformance driven by specific global themes: AI infrastructure, semiconductors, US technology platforms, and Taiwan's supply chain exposure.

Why Global Funds Outperformed

The short answer: global capital is chasing AI.

Markets like the US, South Korea, and Taiwan are seen as the primary builders and enablers of AI infrastructure, data centres, chips, hardware platforms, and cloud services. Global investors have been funnelling capital into these markets because the near-term AI spending cycle is concentrated there.

India is positioned as a long-term beneficiary of AI adoption, in services, software, and enterprise applications, but not as a direct infrastructure play. That distinction mattered in May. Investors betting on who will build AI over the next two to three years were buying US tech, Taiwanese semiconductors, and Korean chipmakers. That's what showed up in the return chart.

This is not a permanent divergence. It reflects where the current investment cycle is focused, not a verdict on India's long-term growth trajectory.

The Return-Chasing Risk Investors Should Not Ignore

A 17% return in one month is attention-grabbing. It is also exactly the kind of data point that leads to poor allocation decisions.

When a fund tops the return chart, it typically means the underlying market has already rallied. The prices that drove those returns are already in. Buying after a sharp run-up means paying a higher price for the same assets, and in markets like the US and Taiwan, valuations are not cheap by historical standards.

Recent performance tells you what worked last month. It does not tell you what will work next month or next year.

Investors who move lump sums into international funds now, because May's return table looked appealing, are making a valuation call they may not fully realise they are making. The US market, in particular, has been trading at elevated multiples. A correction in global tech would hit these funds hard, and the same investors who chased the rally would be the first to exit at a loss.

Domestic Funds Still Had Winners Too

The domestic side was not uniformly weak. Several funds delivered meaningful returns in May:

The domestic pattern was more mixed, and sector selection drove outcomes as much as market direction. Technology-adjacent funds and healthcare performed well. Broader market funds were more muted.

The top of the return chart, however, was unambiguously international.

Should Investors Go Global Now?

The honest answer is: global diversification is sensible, but the timing framing is the wrong question.

Adding global exposure to a portfolio makes structural sense. It reduces dependence on India's market cycle, rupee trajectory, and domestic sector composition. Countries and sectors move differently, and a globally diversified portfolio can smooth out volatility over long periods.

But that rationale is not the same as saying investors should buy international funds aggressively right now, after a sharp one-month rally.

The better framing is this:

• If global diversification was already part of your portfolio plan, continue building it, but gradually.
• If you have no global exposure and are considering starting, a 10–15% allocation is a reasonable starting point for many investors, depending on risk appetite and investment horizon.
• If you are considering a large lump sum into global tech or AI funds because May's return chart looked compelling, that is return-chasing, not diversification.

The decision to go global should be driven by portfolio construction logic, not by what topped last month's performance table.

SIP vs Lump Sum: Why Gradual Allocation Makes Sense

In the current environment, the case for SIP over lump sum for global funds is straightforward.

Global tech and AI-linked markets have already rallied significantly. Valuations in some markets are stretched. Currency movement between the rupee and the dollar adds another layer of uncertainty; a strong rupee can reduce your effective returns even if the underlying market does well.

SIP does not eliminate these risks. But it spreads your entry price across multiple market levels instead of locking you in at one elevated point. If global markets correct after recent highs, SIP investors benefit from lower prices in subsequent instalments. Lump sum investors absorb the full drawdown.

For anyone building a global allocation from scratch, SIP is the more pragmatic choice in this environment.

What Investors Should Check Before Adding International Funds

Strong one-month returns are not a due diligence checklist. Before adding any international fund, investors should look at:

A fund that returned 17% in May could easily give back a large portion of those gains in a correction. That does not make it a bad fund; it makes it a fund that requires understanding before buying.

Key Investor Takeaway

May's return chart is a clear illustration of what global diversification can deliver, and also of why chasing it after a sharp rally is a separate question altogether.

International funds, particularly those linked to AI infrastructure and US technology, outperformed sharply. The structural reasons are real: global capital is concentrated in markets building AI right now, and that is reflected in prices.

But the best-performing markets are also among the most expensive. Valuations in the US, Korea, and Taiwan are not cheap, and currency risk adds complexity for Indian investors.

The right approach is to treat global allocation as a portfolio construction decision, gradual, sized appropriately (10–15% for most), and evaluated over a multi-year horizon. Not as a reaction to one strong month of returns.
