Economy & Markets

Markets have historically looked past political volatility

MFS PERSPECTIVE

  • With the upcoming midterm elections, a divided Congress could be the most favorable outcome for US equities.

  • Midterm election years can be volatile, but since 1938, the S&P 500 has averaged a 19% return in the following year.

  • Staying invested through elections has historically outperformed reacting to political uncertainty.

Earnings growth expanding beyond megacaps

MFS PERSPECTIVE

  • Megacaps’ free cash flows were driven by strong revenue over the past few years, but massive AI capex is expected to pressure cash flows ahead.

  • Mid-caps are expected to generate stronger cash flows, supported by lower AI-related capex and stable earnings.

  • Mid-caps remain less expensive than large caps and continue to outperform in 2026.

Europe: More than a valuation story 

MFS PERSPECTIVE

  • European earnings are rebounding after a weak 2025 and are expected to close the gap with the US by 2027.

  • European earnings are backed by improving fundamentals, while recent US earnings have been partly driven by non-recurring income, or one-off earnings boosts.

  • Improving earnings revisions further support non-US equities.

 

Credit spreads are tighter today than pre-conflict
Inflation expectations remain volatile 

MFS PERSPECTIVE

  • Inflation expectations have rebounded as US-Iran hostilities resumed and the Fed reaffirmed its focus on inflation at Jackson Hole. 

  • Fed Chair Warsh sharpened his messaging and repaired much of the credibility lost at the July FOMC meeting. 

  • With uncertainty high, an active approach to fixed income management is critical.

Positioning chart showing U.S. equities are viewed most favorably relative to emerging markets and non-U.S. developed equities.
 


US

US large-cap equities remain attractive because the growth story is broader than rates.

AI spending, electrification, supply-chain resilience, industrial renewal, and tax policy are helping sustain the cycle, while consumer strength is increasingly tied to wealth effects from rising equity prices.

With these supports for earnings growth still in place, the US market may be less reliant on falling rates than many assume.

 

 

 

 

Emerging Markets

Despite chip stock volatility, EM fundamentals remain solid, and growth is improving, supporting a broad opportunity set from the AI supply chain to industrial metals.

While China’s economy remains weak despite blockbuster IPOs, markets tied to manufacturing, infrastructure, and technology investment appear best positioned to benefit.

 

 

 

 

Non-US Developed

Europe and Japan may offer a way to broaden client equity exposure beyond a US market increasingly defined by the AI trade.

Valuations remain compelling, balance sheets are solid, and improving cash generation could support rerating potential.

Positioning chart showing growth and large-cap stocks are favored over small/mid-cap and value stocks.
 

 

Growth

AI capex remains a key support for US growth equities, but the story is shifting beneath the surface. 

Headline indices may mask meaningful rotation as markets reassess the winners from AI investment and the companies best placed to benefit as AI moves into real-world implementation.

 

 

 

Large Cap

Even allowing for a recent boost from non-operating gains, US large-cap earnings remain robust.

But leadership continues to rotate as the AI landscape evolves and markets reassess winners and identify companies best placed to benefit as AI shifts from an infrastructure buildout to real world adoption.

 

 

 

 

Small/Mid-Cap

The SMID-cap outlook remains constructive. This year’s gains have been driven by rising earnings expectations rather than higher valuations, which leaves the rally on firmer footing.

Valuations remain undemanding, and further upside is likely if rates ease and earnings strength broadens beyond health care and energy.

 

 

 

Value

Value remains the anti-AI trade and offers some of the cleanest diversification from tech-heavy indices. 

A large tech underweight is a near-term headwind, but health care’s earnings outlook is improving as pipelines mature, cost pressures ease, and policy risks fade, with energy and financials offering reasonably valued earnings growth.

Positioning chart showing U.S. investment-grade bonds are most favored, while emerging market debt is least favored.
 

 

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 Q2. 

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

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

 

 

US HY

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

After early widening, spreads are now tighter than pre-war levels.

With valuations rich and technicals weak, we prefer being up in quality.

 

 

 

US Municipals

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

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

 

 

US Securitized

Mortgage yields have risen, while spreads remain historically tight.

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

 

 

 

 

US Treasuries

Geopolitical, fiscal, and monetary concerns have pushed market rates higher.

But even with yields now more compelling, we remain neutral given the policy risks and macro uncertainty.

Technicals are adequate as foreign demand remains healthy.

 

 

EM Debt

Resilient fundamentals and attractive yields remain supportive.

However, spreads are quite tight and may not fully compensate investors for higher uncertainty, leading us to stay selective and favor liquid sovereigns over corporates.
