DIVERSIFICATION AS A DEFENSE — AND AN OPPORTUNITY

WHEN SUPPLY MEETS SCARCITY 

Supply bottlenecks have caused inflation to rise
 

Economy & Markets 

Today’s US economy is less energy intensive. The shift toward a service-based economy has enabled the US to consume less energy for each unit of GDP.
Energy markets have proved adaptable

MFS PERSPECTIVE

  • Despite sharply lower flows out of the Strait of Hormuz, softer demand, alternate routes, and rising US exports eased initial supply concerns even before the MOU was signed.

  • Prices may stay above prewar levels as strategic reserves are replenished.
US equities historically rallied  following high uncertainty. Easing uncertainty tends to lead to a renewed surge in risk appetite and a rally in equity markets.
Opportunities abound beyond megacaps

MFS PERSPECTIVE

  • Earnings growth is expanding beyond megacaps while SMID-cap valuations remain cheaper relative to their large-cap peers.

  • The 2026 cumulative increase in forward earnings expectations for SMID-cap companies is the same or greater than the prior three years combined.

  • Small and mid-caps are outperforming meaningfully in 2026.
European earnings growth looks to close gap with US
European earnings continue to show strength

MFS PERSPECTIVE

  • Even with Europe more exposed to an energy shock, earnings expectations remain robust.

  • The S&P 500 still trades at a 50% premium to the MSCI Europe, even as the earnings growth gap has narrowed, leaving room for that valuation gap to close.

 

Credit spreads are tighter today than pre-conflict
A Fed rate hike can no longer be ruled out over the next year

MFS PERSPECTIVE

  • The Fed, under new Chair Kevin Warsh’s leadership, has reaffirmed its commitment to delivering price stability.

  • The markets currently are predicting a 50 basis-point increase over the next 12 months, in contrast to expectations of 50 basis points of easing at the start of the year.

  • However, given the strength of the US economy, a potential hike will likely be easily absorbed.

Equity regions ranked from less to more favorable: US, emerging markets, and non-US developed.
 


US

Several years of megacap dominance suppressed market breadth, but now earnings growth is expanding, reducing market dependence on a narrow group of leaders.

The percentage of companies experiencing positive revisions has increased, supporting confidence that earnings growth can be sustained should leadership rotate away from AI.

 

 

 

 

Emerging Markets

The outlook for emerging markets is constructive: deep valuation discounts provide a strong starting point, structural growth remains superior to developed markets, and EM economies are increasingly leveraged to the global capex and AI cycle, supporting a gradual re-rating as conditions stabilize.

 

 

 

 

Non-US Developed

Full-year earnings expectations for Europe are rising, narrowing the gap with the US.

As energy pressures ease, Europe and Japan may benefit the most, given their greater manufacturing exposure and the energy sector’s larger weight in regional indices.

Macro

 

 

 

 

US equity segments ranked from more to less favorable across small/mid cap, growth, large cap, and value
 

 

Small/Mid-Cap

Earnings expectations for SMID-cap are improving as the resilient US economy supports revenue growth and stabilizing costs support margins.

Despite improving earnings expectations, mid-caps maintain a meaningful valuation discount relative to large caps and may offer greater opportunity for relative outperformance.

We continue to favor mid-caps over small caps given their valuation discount and improving EPS expectations.

 

 

 

Growth

AI-related names have driven market leadership and must now demonstrate that their large investments in infrastructure are justified.

Valuations in AI-adjacent names reflect significant future growth and may come under pressure should growth expectations falter. 

 

 

 

 

 

Large Cap

Market breadth returned in the first quarter with close to half of S&P 500 stocks outperforming the index.

Earnings are robust, but valuation and concentration remain risks.

We continue to favor large and mid-cap stocks over small-caps.

 

 

 

 

Value

The valuation gap between value and growth has narrowed but remains wide.

2026 earnings estimates have been revised upward year-to-date, supported by the macro backdrop and AI capex spend.

Valuations 

 

 

 

 

Fixed income sectors ranked from less to more favorable, including Treasuries, high yield, investment grade, and municipals.
 

 

US Investment Grade 

Corporate fundamentals are robust, profit margins remain elevated, and free cash-flow generation has been increasing. 

Despite geopolitical uncertainty, the business environment remains strong, as illustrated by remarkable S&P 500 earnings growth in Q1.

Spreads remain tight, but their resilience helps position US IG well compared with purely rate-driven asset classes.

In addition, all-in yields are attractive by historical standards.

 

 

US Municipals

Like Treasuries, municipal valuations have become more attractive, with tax-exempt yields above 3.6%.

Fundamentals have benefited from strong growth in state tax receipts, and strong fund flows are helping absorb a wave of heavy issuance.

 

 

 

US Securitized (MBS)

Mortgage yields have risen, while spreads remain historically tight.

Technicals were strong, supported by $200B in government sponsored enterprises buying of MBS amid limited issuance. Going forward, technicals may soften while valuations are rich. 

 

 

 

US High Yield

Geopolitical uncertainty hurt sentiment as growth fears pushed recent fund flows into negative territory.

After early widening, spreads are now tighter than prewar levels.

With valuations rich and technicals weak, we favor IG corporates over HY.

 

 

 

 

US Treasuries

The geopolitically driven rise in rates has helped improve the duration backdrop, with US Treasury valuations now more compelling.

Technicals remain reasonable as the market’s appetite for dollar assets has rebounded.

 

 

EM Debt

Despite some countries being directly impacted by the geopolitical crisis, EM spreads are tighter than pre-conflict levels. 

Current spreads don’t seem to compensate investors for elevated uncertainty, leaving us cautious on the asset class.
