FTSE 100 winners and losers: Beazley, Schroders, Glencore and BAE Systems led Q1 2026; Barratt Redrow, Berkeley and Entain trailed. Full UK breakdown.

FTSE 100 companies have produced striking dispersion in 2026 so far, with the index up 22.8% year-to-date through Q1 and a handful of names contributing disproportionately to that return, per AJ Bell analysis. Beazley led with a 55% gain over Q1, Schroders added 41% and Glencore returned 39%, while housebuilders Barratt Redrow and Berkeley Group lost 32% and 27% respectively. The breakdown of FTSE 100 winners and losers offers a clearer picture of where UK Equity returns have actually come from this year.

The Top Five Winners of Q1 2026

Beazley (LSE: BEZ) led the FTSE 100 in Q1 2026 with a 55% share-price gain, per AJ Bell. The Lloyd's of London insurer has benefited from disciplined Underwriting in property and cyber lines, alongside a stable Reinsurance pricing environment. Beazley's combined ratio has remained well inside the 90% threshold that defines profitable underwriting, supporting steady book-value growth and an investor-friendly Capital return policy.

Schroders (LSE: SDR) was the second-best performer with a 41% Q1 gain, per AJ Bell. The asset management group has benefited from the strong year-to-date performance of UK and global equity markets, which lifts Assets under management and management fees in lockstep. Schroders also benefits from net inflows into its Wealth-management/">Wealth Management Subsidiary, which represents a higher-Margin Business line within the group.

Glencore (LSE: GLEN) returned 39% over Q1, driven by sustained copper pricing and the broader resources-sector recovery. Glencore's combination of Mining and trading exposure provides a unique business model among FTSE 100 miners, with the trading division generating Revenue even during periods of subdued mining-margin profitability.

BAE Systems (LSE: BA.) added 27% over Q1, per AJ Bell, as Iran-US tensions and ongoing European defence commitments lifted forward order books across the FTSE 100 defence complex. BAE's Eurofighter, submarine and naval shipbuilding franchises all benefit from sustained NATO spending commitments and the broader rearmament narrative.

The Five Worst Performers of Q1 2026

Barratt Redrow (LSE: BTRW) was the worst-performing FTSE 100 stock in Q1, losing 32% of its Market Value, per AJ Bell. The housebuilder has been pressured by UK Mortgage-rate uncertainty, weakening consumer affordability and political uncertainty around the post-election housing policy framework. Reservation rates have come under pressure even as the company maintains its forward Dividend commitment.

Berkeley Group Holdings (LSE: BKG) lost 27% over Q1 in a closely matched decline to its sector peer. Berkeley's London-and-Southeast focus exposes it to the most challenged sub-segments of the UK housing market, where premium pricing intersects with mortgage-cost pressure. The company's land bank remains an asset, but the timing of monetisation in the current market is uncertain.

Entain (LSE: ENT) lost 25% over Q1 as the gambling group continues to navigate regulatory uncertainty in multiple jurisdictions. UK gambling reforms and the ongoing US sports-betting state-by-state rollout both create Regulatory Risk that has weighed on the share price, even as the underlying business remains cash-generative.

ICG (LSE: ICG) lost 24% over Q1, reflecting broader pressure on alternative asset management firms. Performance fees have been variable, distribution to limited partners has lagged some peer benchmarks, and competitive pressure on fundraising has compressed the previously elevated multiple investors had assigned to ICG's Franchise. The combination has produced a sharp share-price reset.

easyJet (LSE: EZJ) lost its FTSE 100 status during Q1, tumbling into the FTSE 250, per AJ Bell. Rising fuel costs, capacity discipline issues and competitive pricing pressure on European short-haul routes combined to weigh on the share price enough to trigger the demotion.

Sector Patterns Behind the Dispersion

Insurance and asset management have been the standout outperforming sectors of 2026 so far. Beazley and Schroders, alongside other insurance and wealth names not in the top-five list, have collectively driven much of the FTSE 100's headline return. The combination of disciplined underwriting in insurance and Beta-driven AUM growth in asset management has produced an unusually favourable backdrop for both sectors.

Mining and natural resources have been the second-strongest sector cluster, anchored by Glencore's 39% Q1 return. Sustained copper pricing, the broader recovery in industrial-metals Demand and Iran-driven Volatility in energy-and-Commodity-related themes have all supported the sector. Antofagasta and Anglo American have delivered solid if less dramatic returns alongside Glencore.

Housebuilders represent the largest underperforming sector cluster. Barratt Redrow, Berkeley Group, Persimmon and Taylor Wimpey have all faced the same combination of mortgage-rate sensitivity, affordability pressure and political uncertainty. The sector is a near-perfect counterpoint to the insurance and asset-management strength.

Defence and aerospace, led by BAE Systems and Rolls-Royce, has been the geopolitical-tailwind sector of choice. The combination of Iran-driven uncertainty, ongoing European rearmament and the structural NATO spending commitment of 2-2.5% of GDP across member states has lifted order books and share prices across the defence cluster.

FTSE 100 vs S&Amp;P 500 Year-to-Date

The FTSE 100's 22.8% year-to-date return through Q1 2026 has materially outpaced the S&P 500's 17.2% return over the same period, per AJ Bell. That gap is notable given the long history of US large-cap outperformance over the post-2009 Bull Market period and the dominance of US technology in global equity returns through much of 2024 and 2025.

Three structural factors explain the FTSE 100's 2026 outperformance. First, the index's heavy weighting in energy and mining has benefited from sustained Brent Crude prices and copper strength. Second, the limited technology weighting has insulated the FTSE 100 from the periods of US technology consolidation seen earlier in the year. Third, the higher Yield/">Dividend Yield on FTSE 100 constituents has provided total-return support against a backdrop of moderating bond yields.

Currency translation matters for UK investors holding US exposure and US investors holding UK exposure. The GBP/USD trajectory through 2026 has been broadly range-bound, meaning the headline index return differential has translated through to investor portfolios with limited FX dilution.

Looking ahead, the question for UK investors is whether the FTSE 100's 2026 outperformance can persist into the back half of the year. That depends partly on Iran-US resolution, partly on continued Earnings discipline among index constituents and partly on the trajectory of the Bank of England's rate-cut path against the Federal Reserve's evolving stance.

What the Dispersion Means for UK Investors

The dispersion in FTSE 100 returns through 2026 highlights the case for active stock-selection over passive index-tracking in periods of significant sector divergence. While passive holders of FTSE 100 trackers have captured the headline 22.8% return through Q1, active investors who concentrated exposure in the leading sectors and avoided the trailing sectors have captured materially higher returns.

For ISA and SIPP investors building long-term positions, the practical implication is that single-stock concentration risk works both ways: it amplifies returns when bets pay off and amplifies losses when they don't. Beazley's 55% Q1 gain and Barratt Redrow's 32% decline both occurred inside the same index over the same quarter.

The FTSE 100's high dividend yield — typically in the 3-4% range — provides a meaningful income component for total-return investors. UK insurance, mining and energy names contribute disproportionately to that yield, with several holdings paying 5-7% trailing yields. Income-focused investors can construct portfolios that capture the yield without taking single-sector concentration risk.

For investors using global tracker funds such as Vanguard's FTSE All-World or FTSE Global All Cap, the UK weighting is around 4% of total portfolio. Investors with a strong view on FTSE 100 outperformance through 2026 might supplement the global tracker with a UK-specific overlay; those without a strong view should let the global allocation work as designed.

Risks and What to Watch in H2 2026

The most significant risk for FTSE 100 investors in the back half of 2026 is a sharp resolution to the Iran-US standoff. A confirmed peace memorandum would compress oil prices and weigh on the energy-and-defence cluster that has driven much of the year-to-date return. The unwind could move the index by several percentage points in a single session.

Housebuilder underperformance could reverse on any combination of Bank of England rate cuts, post-election housing-policy clarification and improving affordability metrics. Investors looking for contrarian-value opportunities within the FTSE 100 should monitor the housebuilders for inflection-point signals through Q3 and Q4 2026.

Asset-manager and insurance sector momentum could fade if global equity markets pull back. Schroders, Beazley and similar names rely on either AUM or insurance pricing dynamics that are correlated with broader market conditions. A 10-15% equity market drawdown would compress AUM-based fees and underwriting volumes simultaneously.

What to watch: the UK general election outcome and subsequent fiscal-policy direction, Bank of England rate decisions through Q3 and Q4, ongoing Iran-US headlines, US Federal Reserve policy under the second Trump administration, and Chinese property and Manufacturing data that affect FTSE 100 miner earnings. Each could shift the FTSE 100 winners-and-losers leaderboard meaningfully through the back half of 2026.

Index composition changes also matter for the watch list. The FTSE 100 quarterly review reshuffles constituents based on Market Capitalisation, and easyJet's demotion to the FTSE 250 during Q1 2026 illustrates how quickly the underlying constituents can change. Investors using FTSE 100 trackers should be aware that the index they hold today will look different a year from now, with weaker constituents demoted and stronger ones promoted from the FTSE 250.

Practical Lessons from the 2026 Dispersion

The first lesson from 2026's dispersion is that sector concentration matters at least as much as headline-index direction. A UK investor who held an equal-weighted basket of housebuilders alongside an equal-weighted basket of FTSE 100 insurers and miners would have experienced very different return paths through Q1, despite both baskets being inside the same headline index.

The second lesson is that contrarian positioning requires patience. Housebuilders may eventually mean-revert as UK mortgage rates ease and political uncertainty resolves, but the timing is genuinely uncertain. Investors taking contrarian housebuilder positions need a multi-quarter time horizon and conviction in the eventual narrative shift.

The third lesson is that defence and insurance are not infinitely scalable trends. BAE Systems' 27% Q1 return and Beazley's 55% Q1 return reflect the early innings of the rearmament cycle and the discipline of the Lloyd's market respectively, but each sector eventually faces valuation headwinds when the easy upside is captured.

The fourth lesson is that asset-manager performance — Schroders' 41% Q1 — is highly correlated with the broader equity-market backdrop. Investors using asset-manager stocks as a leveraged bet on global equity strength should size the position accordingly and prepare for sharper drawdowns during equity-market corrections than the underlying market itself produces.

Conclusion

FTSE 100 companies have produced unusually wide dispersion through 2026 so far, with Beazley, Schroders, Glencore and BAE Systems delivering 27-55% Q1 gains while Barratt Redrow, Berkeley Group, Entain and ICG lost 24-32%. The headline 22.8% YTD return masks both the breadth of the rally and the depth of the housebuilder drawdown. For UK investors, the implications are twofold: passive holders capture the broad index gain, and active investors face genuine opportunities to outperform through sector selection. The H2 2026 outlook depends on Iran-US resolution, Bank of England policy direction and global equity-market conditions.
