Legal & General UK 100 Index tracks the FTSE 100 Index, a benchmark consisting of the UK’s 100 largest companies and representing approximately 85% of the UK equity market. The fund uses full physical replication to mirror the index’s performance.
The index leaves investors underexposed to UK small-cap stocks, which reduces the likelihood of consistently outperforming better-diversified peers in the UK large-cap equity Morningstar Category. That said, this does not mean a passive fund tracking the FTSE 100 Index cannot outperform one tracking the FTSE All-Share Index. Over shorter periods, such as one or even several years, UK large caps can lead the market. However, these episodes of outperformance do not change our view that more diversified passive options remain preferable for investors seeking a core UK equity holding.
The FTSE 100 Index has historically been a difficult benchmark for active managers to outperform. The fund has delivered superior risk-adjusted returns compared with the average peer in the EAA fund UK large-cap equity category over the trailing three-, five-, and ten-year periods.
LGIM’s Index team is composed of experienced professionals and operates with a collaborative management structure, where each fund is overseen by both a lead and a secondary manager. The team is supported by dedicated groups specializing in investment strategy, regulatory compliance, and data analytics. Portfolio management is carried out using IND1GO, LGIM’s multi-asset platform for modeling, optimization, and risk monitoring.
Overall, we acknowledge the advantages of a passive approach to the UK equity market. Given its meaningful cost advantage, Legal & General UK 100 Index can deliver above-average returns over the long term. The fund maintains a minimal level of tracking error, and Morningstar has a positive view of the experienced portfolio management team. Additionally, the fund benefits from the compounding effect of low fees across most of its share classes. However, the index’s emphasis on large- and mega-cap companies may limit its return potential during periods when smaller-cap stocks lead the market.
Legal & General UK 100 Index Trust: Performance Highlights
The UK equity market has continued to build on the strong momentum established in 2025, when the FTSE 100 Index delivered a total return of more than 25%—a notable acceleration from the more modest single-digit annual gains recorded between 2022 and 2024. This positive trend has extended into 2026. Performance has continued to be driven primarily by the financials sector, with banks representing the largest constituent of the index. Industrials and healthcare have also made meaningful positive contributions, while the technology sector has acted as a drag on overall returns. Mega-cap stocks have continued to outperform the broader UK equity market, enabling the index to outperform the FTSE All-Share Index over the past year.
The FTSE 100 has remained a challenging benchmark for active managers to outperform. Over the past five years, funds tracking the index have consistently ranked in the first or second quartile of their peer group on both absolute and risk-adjusted return measures, underscoring the difficulty active managers have faced in generating consistent outperformance.
