A UK DIY Investor’s Guide to the Year Ahead
Clearly Investments | 02 January 2026
The biggest investment banks have published their 2026 outlooks, and while they don’t always agree on details, a clear consensus emerges: expect steady growth, modest rate cuts, and earnings-driven market gains—not multiple expansion. Here are seven themes worth understanding for your portfolio.
1. Soft Landing: Growth Holds at 2.7–2.8%
Goldman Sachs forecasts global GDP at 2.8%, with the US at 2.6%, China at 4.8%, and the eurozone at 1.3%. Bank of America is similarly bullish on US growth (2.4%), crediting AI investment, fiscal stimulus, and supportive trade conditions. Morgan Stanley frames 2026 as “The Year of Risk Reset”—focus shifts from macro worries to company fundamentals, signalling confidence in resilience.goldmansachs+2
The risk: China’s property sector still drags growth by ~1.5 percentage points, and major trade-war escalation could disrupt supply chains. But the consensus is clear—no recession in the base case.
For your portfolio: Overseas exposure (US, Asia) remains valuable given the UK’s modest 2% growth trajectory. Diversification across regions hedges timing risk.
2. Inflation: Sticky but Moving
Goldman Sachs expects US core PCE to fall to policy targets (~2%), though the path is uneven due to tariff pass-through and slowing wage growth. Bank of America sees inflation staying “above target” at 2.6–2.8%, with third-quarter pressure from tariffs. Morgan Stanley expects fixed-income to rally in H1 2026 as central banks shift from fighting inflation to “equilibrium management.”
Disagreement exists: Some banks (BofA, Citi) worry sticky service prices and tariff effects could delay disinflation longer than others expect. Goldman is more optimistic, noting that excluding tariffs, US inflation has already fallen to 2.3%.goldmansachs
For your portfolio: Bonds and cash are attractive again. A 60/40 portfolio (60% equities, 40% bonds/cash) makes sense once more. Assume UK inflation at ~2.5% for retirement planning.
3. Rate Cuts: 50bps Fed Move, Modest UK Easing
Goldman Sachs projects the Fed will cut 50 basis points to 3–3.25%, with the Bank of England making sequential cuts to 3% by Q3 2026. Bank of America expects two Fed cuts with 10-year Treasury yields ending around 4–4.25%. Citi cautions that inflation will “constrain” cuts, so don’t expect aggressive easing.
The gap: Markets may be pricing in too many cuts if the economy stays resilient. But Deutsche Bank notes policy is shifting from “expansionary” to “neutral”—not tightening, just normalising.
For your portfolio: Don’t expect 5%+ savings rates to persist; lock in longer-term fixed bonds if you want stable income. Gilt prices may rally if more rate cuts are priced in, offering price appreciation for bond holders.
4. Earnings Drive Returns, Not Price Gains
Morgan Stanley projects S&P 500 EPS to grow 17% in 2026 (from $272 to $317), driven by pricing power, AI efficiency, tax cuts, and stable rates. Barclays forecasts $305 EPS with 8% European growth. Citi estimates global EPS at $320 with 11% growth broadening across regions.
But here’s the catch: Bank of America, the most bearish, projects 14% EPS growth yet only 4% index upside—implying stretched valuations mean stock price gains lag earnings. Others (Deutsche Bank to 8,000, Morgan Stanley to 7,800) assume multiple expansion stays intact.
For your portfolio: Focus on earnings quality, not momentum. A 15% stock gain with just 5% earnings growth is risky. Favour quality companies with durable competitive advantages.
5. AI Capex: Early Innings, Real Monetization Questions
Morgan Stanley emphasizes AI’s capex cycle is “early stages”—only ~20% of the estimated $3 trillion in data-center spend has been deployed. But UBS warns: monetisation depends on “investors’ willingness to fund AI, tech leaders’ ability to monetise, and the world’s energy capacity.” Goldman Sachs is cautious, noting “largest AI productivity benefits are still years off” with gains confined to tech so far.
Citi sees a shift coming: focus moves from “AI enablers” (hyperscalers, chips) to “AI adopters” (enterprise software, industrials), broadening the opportunity set.
For your portfolio: AI hype is real but isn’t a licence to overpay for tech stocks. If you own Big Tech, take profits on rallies. For diversified portfolios, some semiconductor and AI exposure makes sense, but avoid concentration. Watch energy and utilities—data centres need lots of electricity.
6. Market Broadening: US Leads, EM Has Upside
Goldman Sachs notes emerging markets trade at a 40% P/E discount to US equities; this discount should narrow. Morgan Stanley projects S&P 500 gains of 14%, but MSCI Europe just 4% and Japan 7%, signalling US dominance—yet German fiscal stimulus could help European industrials and utilities. UBS highlights China tech as a “top global opportunity” with 37% EPS growth expected.
Barclays favours Financials and Utilities alongside Tech, emphasising broadening leadership beyond mega-cap dominance. HSBC sees AI adoption spreading into industrials and utilities (grid modernization).
For your portfolio: Avoid pure US mega-cap concentration. A typical 2026 allocation: 40–50% US, 20–25% developed Europe/Japan, 20–25% emerging markets. Use low-cost regional ETFs to capture the broadening story.
7. The K-Shaped Economy: Rich Thrive, Mass Market Weakens
Bank of America emphasizes “resilient spending from higher-income households and retiring boomers” while lower-income groups face inflation, weak wage growth, and tight credit. Job growth is slowing to ~50,000 per month. HSBC calls this a “two-speed economy”: affluent households spend more; lower-income groups trade down to discount retailers. Goldman Sachs notes job growth is “well below pre-pandemic rates,” highlighting wage-growth divergence.
For your portfolio: Favour consumer staples (Tesco, Sainsbury’s) over luxury goods. UK house prices likely stay subdued due to affordability pressures. Assume 2–3% real wage growth in retirement planning. Diversify beyond the UK consumer; many FTSE 100 stocks earn overseas.
The Bottom Line
Bank targets for the S&P 500 range from 7,100 (BofA, 4% upside) to 8,000 (Deutsche Bank, 21% upside). Don’t chase that spread. Instead, focus on:
- Asset allocation: 60/40 portfolios make sense again.
- Diversification: Own regions, sectors, and asset classes—pockets of gain will surprise you.
- Costs: Use low-cost index funds (0.2–0.5% fees).
- Behaviour: Ignore volatility; stick to your plan.
- Regular review: Check your portfolio, but not daily.
Growth will be OK. Inflation is tamed. Earnings will grow 11–17%. Valuations are stretched. That’s your framework for 2026.
