CAPITAL AT RISK. MARKETING MATERIAL.
Opening frame: What’s driving markets? Market take
Camera frame
Title slide: Upgrading developed equities
Mega forces are reshaping portfolio opportunities over a strategic horizon of five years or more. Their latest manifestation shifts where we take growth risk.
1: Multiple possible outcomes
Markets are being pulled in different directions by competing mega forces, namely AI and geopolitical fragmentation. AI is driving stocks higher, but we can’t say for sure what mega force will dominate over the long term. That’s why our capital market assumptions – for professional investors only – anchors to multiple plausible scenarios.
In one, AI could drive a productivity boom that supports growth, earnings and equity valuations. In another, geopolitical fragmentation fuels stagflationary pressure, resulting in weaker equity valuations as investors demand more compensation for taking growth risk. Our starting point represents our latest thinking of how these mega forces will evolve.
2. Strong earnings boost developed market stocks
Earnings momentum for developed market stocks looks strong. Only three quarters since 1988 have seen bigger jumps in expected 24-month U.S. equity earnings than we’ve seen for each of the past two quarters.
AI’s impact is also cutting across asset class labels, as the tech sector is now a larger share of the MSCI Emerging Markets index than for the S&P 500. The granular impact of mega forces underpins our developed equity upgrade and existing emerging equity overweight on a strategic horizon of five years or more.
3. Total portfolio implications
Our upgrade of developed equities means reducing exposure to fixed income. We like high yield in fixed income, but don’t build portfolios in asset class silos. So we downgrade high yield on a strategic horizon because we prefer to take growth risk through equities. We reduce developed market government bonds to underweight and continue to prefer inflation-linked government bonds. Why? We prefer to hold less duration risk at the total portfolio level and see inflation being more persistent than markets expect.
Outro: Here’s our Market take
Solid momentum in earnings growth leads us to upgrade developed market equities over a longer-term horizon. We adjust for that by downgrading high yield credit.
Closing frame: Read details: blackrock.com/weekly-commentary
AI-driven earnings upgrades lead us to upgrade DM equities on a strategic basis. We downgrade high yield as we prefer taking growth risk through stocks.
AI optimism and policy caution drove markets last week: the S&P 500 hit record highs on strong earnings, while bond yields rose as Fed cut expectations faded.
European and Japanese data this week should show whether high energy costs and supply disruptions are feeding into inflation and production hiccups.
Stocks are rallying on strong AI earnings expectations, offsetting jitters over inflation pressures from geographical fragmentation such as the Middle East supply shock. That could change in the near term, but we look beyond this in our strategic views when we see these mega forces - big, structural trends - in action. We upgrade developed market stocks to overweight and downgrade high yield to neutral as we shift where we take growth risk on a horizon of five years or more.
Multiple outcomes

Forward –looking estimates may not come to pass. Past performance is not a reliable indicator of current or future results. Source: BlackRock Investment Institute, with data from Robert Shiller, (Yale University), May 2026. Note: The line shows the forward price-earnings ratio of U.S. equities, the markers indicate future estimates of the ratio across various scenarios.
Markets are being pulled in different directions by competing mega forces. AI is driving stocks higher today, but we cannot say which force will dominate in the long run. That’s why our capital market assumptions (for professional investors only) are built on multiple scenarios that imply fundamentally different macro paths. Our starting point (the green dot) reflects our latest thinking, and the gap between outcomes shows how mega forces could affect outcomes over a five-year period. In one, AI drives a productivity boom that could sustain stronger growth and earnings, justifying higher equity valuations over the strategic horizon, as the chart’s pink dot shows. In another, geopolitical fragmentation fuels stagflationary pressures that push global risk premia higher as investors demand greater compensation for uncertainty. This would lower equity valuations, as the purple dot shows.
For now, AI-driven earnings momentum looks strong: Upgrades to MSCI U.S. 2026 and 2027 earnings expectations in the past two quarters rank in the top five since 1988. And it’s broadening: The gap between expected “magnificent seven” earnings growth and the rest of the S&P 500 in 2027 has narrowed to 3 percentage points, down from 31% in 2024. Leadership is also broadening across regions and sectors, as AI reshapes markets beyond asset classes. The technology sector is a larger share of the MSCI EM Index than it is of the S&P 500, reflecting Taiwan’s and South Korea’s key role in the AI supply chain. All this underpins our DM equities upgrade and existing EM equities overweight on a long-term horizon. We view these not as broad market exposures but through sectors and regions. Within DM equities, we favor technology, AI-adopters such as health care and energy sectors tied to the AI buildout and rising power demand. We also favor EM tied to AI supply chains, including Taiwan and South Korea. We see India stocks benefiting from the demographic mega force: a growing workforce.
To fund the DM equities upgrade, we reduce our fixed income exposure in our strategic portfolios. Within this segment, we like high yield as it offers attractive income with less duration, or sensitivity to interest rate swings, than investment grade credit. But we don’t build portfolios in asset class silos. Similar to a total portfolio approach, we prefer taking growth risk in equities, leading us to downgrade high yield to neutral. The reason: Investors can participate in equity upside rather than be capped by coupon income. We also downgrade DM government bonds to underweight, leaving our long-term portfolios with less duration risk than our benchmark. We overweight inflation-linked bonds as we expect inflation to be more persistent than markets currently price over a strategic horizon of five years or more.
The clash of mega forces across asset classes this year reinforces the need for a dynamic, scenario-based approach to navigate uncertain outcomes. We see the industry increasingly recognizing this shift through greater focus on total portfolio approaches that cut through asset class labels. A prime example is investing in infrastructure. We think infrastructure can do well under all our scenarios as it has historically been resilient in periods of market stress. Most investors can up their holdings materially, depending on their tolerance for illiquidity risk, or the risk of being unable to sell an investment quickly.
We upgrade DM equities on a strategic basis due to AI-driven earnings momentum strength. We downgrade high yield to neutral as we prefer to take growth risk in equities but still like it for income in a fixed income context.
The S&P 500 last week notched another record high as investors kept their focus on strong AI-driven earnings before slipping on Friday. U.S. Treasury yields jumped to around 4.56% as investors scaled back expectations for Federal Reserve rate cuts while oil prices remained well above pre-conflict level amid ongoing supply disruptions caused by the Middle East conflict. Brent crude remained near $105, more than 40% above pre-conflict levels.
This week’s focus is on inflation data from the UK and Japan, along with early signals on global production. Japan CPI will likely show how higher energy costs tied to the Middle East conflict are feeding into price pressures, while flash PMIs will indicate whether supply disruptions and rising costs are starting to weigh on activity.

Our highest conviction views on six- to 12-month (tactical) and over five-year (strategic) horizons, May 2026
| Reasons | ||
|---|---|---|
| Tactical | ||
| Favor AI beneficiaries | We favor infrastructure and equipment supporting the AI buildout such as semiconductors, power and data centers. We think they stand to benefit no matter AI’s eventual winners or losers. We see the AI boom lifting U.S. corporate earnings. underpinning our U.S. equity overweight. | |
| Selected international exposures | We like hard-currency EM debt on economic resilience, disciplined fiscal and monetary policy and a high ratio of commodities exporters. We’re also overweight EM equities, preferring commodity exporters and AI beneficiaries. In Europe, we favor equity sectors like infrastructure. | |
| Evolving diversifiers | We suggest looking for “plan B” portfolio hedges such as thematic opportunities related to the AI built-out and search for energy security. Long-term U.S. Treasuries no longer provide a buffer against equity market declines, and gold also has shown to be an ineffective diversifier. | |
| Strategic | ||
| Portfolio construction | We favor a scenario-based approach as AI winners and losers emerge. We lean on private markets and hedge funds for idiosyncratic returns and to anchor portfolios in mega forces. | |
| Infrastructure equity and private credit | We find infrastructure equity valuations attractive as geopolitical fragmentation and the AI build-out underpin structural demand. We still like private credit but see an increase in dispersion of returns. This highlights the importance of manager selection. | |
| Beyond market cap benchmarks | We get granular in public markets. We favor DM government bonds outside the U.S. Within equities, we favor EM over DM – and get selective in both. In EM, we like India because it sits at the intersection of mega forces. In DM, we like Japan amid inflation and corporate reforms. | |

Six- to 12-month tactical views on selected assets vs. broad global asset classes by level of conviction, May 2026

We have lengthened our tactical investment horizon back to six to 12 months. The table below reflects this and, importantly, leaves aside the opportunity for alpha, or the potential to generate above-benchmark returns – especially at a time of heightened volatility.
Six- to 12-month tactical views on selected assets vs. broad global asset classes by level of conviction, May 2026
| Asset | Tactical view | Commentary | ||||
|---|---|---|---|---|---|---|
| Equities | ||||||
| United States | We are overweight. Contained damage to global growth from the Mideast conflict and strong earnings expectations – particularly in tech – keep us risk-on. | |||||
| Europe | We are neutral. Europe’s high exposure to the energy shock from the Mideast conflict makes it vulnerable to higher inflation and lower growth. | |||||
| UK | We are neutral. Valuations remain attractive relative to the U.S., but we see few near-term catalysts to trigger a shift. | |||||
| Japan | We are neutral. Japan’s exposure to imported energy may erode strong equity gains powered by healthy corporate balance sheets and governance reforms. | |||||
| Emerging markets (EM) | We are overweight yet stay selective. We favor Asian countries that manufacture critical AI components and Latin American energy and commodity exporters. | |||||
| China | We are neutral. Trade relations with the U.S. have steadied, but property stress and an aging population still constrain the macro outlook. Relatively resilient activity limits near-term policy urgency. We like sectors like AI, automation and power generation. | |||||
| Fixed income | ||||||
| Short U.S. Treasuries | We are neutral. Shorter-term bonds are relatively attractive as the market has woken up to persistent inflation and higher rates. | |||||
| Long U.S. Treasuries | We are underweight. Yields already faced upward pressure from rising term premia, as investors demand more compensation for the risk of holding long-term debt. The recent energy price shock compounds this by aggravating pre-existing inflationary pressures. | |||||
| Global inflation-linked bonds | We are neutral. We think inflation will settle above pre-pandemic levels, but markets may not price this in the near term as growth cools. | |||||
| Euro area government bonds | We are neutral short-term European government bonds. The market has repriced the ECB policy path more in line with our view. We think increased German bond issuance to finance its fiscal stimulus package is already largely reflected in the current level of 10-year yields. | |||||
| UK gilts | We are neutral. We expect volatility in gilts over the near-term. Gas powers much of the UK’s electricity, but storage is limited – making it especially vulnerable to a resurgence in inflation. | |||||
| Japanese government bonds | We are underweight. Rate hikes, higher global term premium and heavy bond issuance will likely drive yields up further. | |||||
| China government bonds | We are neutral. China bonds offer stability and diversification but developed market yields are higher and investor sentiment shifting towards equities limits upside. | |||||
| U.S. agency MBS | We are overweight. Agency MBS offer higher income than Treasuries with similar risk, and may offer more diversification amid fiscal and inflationary pressures. | |||||
| Short-term IG credit | We are neutral. Corporate strength means spreads are low, but they could widen if issuance increases. | |||||
| Long-term IG credit | We are underweight. We prefer short-term bonds less exposed to interest rate risk over long-term bonds. | |||||
| Global high yield | We are neutral. High yield offers more attractive carry and shorter duration, but we think dispersion between higher and weaker issuers will increase. | |||||
| Asia credit | We are neutral. Overall yields are attractive and fundamentals are solid, but spreads are tight. | |||||
| Emerging hard currency | We are overweight. EM hard-currency indexes lean towards Latin American commodity exporters such as Brazil that stand to benefit as Mideast supply plummets. | |||||
| Emerging local currency | We are neutral. The U.S. dollar has been strengthening as a safe-haven currency in the wake of the Middle East conflict. This could reverse year-to-date gains driven by a falling USD. | |||||

We have lengthened our tactical investment horizon back to six to 12 months. The table below reflects this and, importantly, leaves aside the opportunity for alpha, or the potential to generate above-benchmark returns – especially at a time of heightened volatility.
| Asset | Tactical view | Commentary | ||
|---|---|---|---|---|
| Equities | ||||
| Europe ex UK | We are neutral. We would need to see more business-friendly policy and deeper capital markets for recent outperformance to continue and to justify a broad overweight. We stay selective, favoring financials, utilities and healthcare. | |||
| Germany | We are neutral. Increased spending on defense and infrastructure could boost the corporate sector. But valuations rose significantly in 2025 and 2026 earnings revisions for other countries are outpacing Germany. | |||
| France | We are neutral. Political uncertainty could continue to drag corporate earnings behind peer markets. Yet some major French firms are shielded from domestic weakness, as foreign activity accounts for most of their revenues and operations. | |||
| Italy | We are neutral. Valuations are supportive relative to peers. Yet we think the growth and earnings outperformance that characterized 2022-2023 is unlikely to persist as fiscal consolidation continues and the impact of prior stimulus peters out. | |||
| Spain | We are overweight. Valuations and earnings growth are supportive relative to peers. Financials, utilities and infrastructure stocks stand to gain from a strong economic backdrop and advancements in AI. High exposure to fast-growing areas like emerging markets is also supportive. | |||
| Netherlands | We are neutral. Technology and semiconductors feature heavily in the Dutch stock market, but that’s offset by other sectors seeing less favorable valuations and a weaker earnings outlook than European peers. | |||
| Switzerland | We are neutral. Valuations have improved, but the earnings outlook is weaker than other European markets. If global risk appetite stays strong, the index’s tilt to stable, less volatile sectors may weigh on performance. | |||
| UK | We are neutral. Valuations remain attractive relative to the U.S., but we see few near-term catalysts to trigger a shift. | |||
| Fixed income | ||||
| Euro area government bonds | We are neutral short-term European government bonds. The market has repriced the ECB policy path more in line with our view. We think increased German bond issuance to finance its fiscal stimulus package is already largely reflected in the current level of 10-year yields. | |||
| German bunds | We are neutral. Markets have largely priced in fiscal stimulus and bond issuance, and expectations for policy rates align with our view. | |||
| French OATs | We are neutral. Political uncertainty, high budget deficits and slow structural reforms could stoke volatility, but current spreads incorporate these risks and we don’t expect a worsening from here. | |||
| Italian BTPs | We are neutral. Demand from Italian households is strong at current yield levels. Spreads tightened in line with its sovereign credit upgrade, but a persistently high debt-to-GDP levels means they likely won’t tighten further. | |||
| UK gilts | We are neutral. We expect volatility in gilts over the near-term. Gas powers much of the UK’s electricity, but storage is limited – making it especially vulnerable to a resurgence in inflation. | |||
| Swiss government bonds | We are neutral. We don’t think the Swiss National Bank will slash policy rates to below zero, as markets expect. | |||
| European inflation-protected securities | We are neutral. Our medium-term inflation expectations align with those implied in current market pricing. | |||
| European investment grade | We are neutral. We favor short- to medium-term debt and Europe over the U.S. An intense re-leveraging cycle to support the AI buildout could put upward pressure on U.S. spreads, making Europe relatively more attractive. | |||
| European high yield | We are overweight. Spreads hover near historic lows, but credit losses have been limited in this cycle and better economic growth in 2026 could reduce them further. | |||
