Introduction and Overview of the FTSE NSX Index Series

The FTSE NSX Index Series represents a key benchmark designed to measure the performance of equities listed in Iceland. Developed and maintained by FTSE Russell, a subsidiary of the London Stock Exchange Group, this index series plays a vital role in providing investors with a structured and transparent view of the Icelandic stock market.

As global investing has become increasingly data-driven, the demand for reliable and rules-based indices has grown significantly. The FTSE NSX Index Series addresses this need by offering a consistent framework for tracking equity performance within a single-country context. It serves a wide audience, including institutional investors, asset managers, financial advisors, and researchers who rely on accurate benchmarks for portfolio construction and performance evaluation.

The index focuses on companies listed on Nasdaq Iceland, ensuring that it reflects the investable universe of Iceland’s equity market. By applying a systematic and transparent methodology, the index captures the underlying dynamics of the market while maintaining consistency and replicability. This makes it suitable for both passive investment strategies, such as index funds and ETFs, and active portfolio benchmarking.

Over time, the FTSE NSX Index Series has evolved to accommodate changes in market structure, investor preferences, and regulatory frameworks. Despite these developments, it continues to uphold the core principles of transparency, consistency, and investability that define all FTSE Russell indices.

In broader financial markets, indices play an essential role in standardising performance measurement and enabling the creation of index-linked products. The FTSE NSX Index Series fulfils these functions within the Icelandic market, making it a cornerstone benchmark for investors seeking exposure to this region.

Understanding this index requires both a technical and practical perspective. From a technical standpoint, it relies on clearly defined rules for selecting constituents, assigning weights, and rebalancing the portfolio. From a practical standpoint, it forms the basis of investment strategies and products that allow investors to access Iceland’s equity market efficiently.

History and Evolution of the FTSE NSX Index Series

Origins and Launch

The FTSE NSX Index Series was established through collaboration between FTSE Russell and Nasdaq Iceland to create a globally recognised benchmark for Icelandic equities. Its introduction addressed the need for a unified and transparent index that could serve as a reliable reference point for investors.

Before its launch, market participants relied on fragmented benchmarks that lacked consistency and comparability. The introduction of this index helped standardise performance measurement, improving transparency and efficiency in investment decision-making.

The timing of its launch also coincided with the rapid growth of passive investing. As investors increasingly sought cost-effective and systematic investment approaches, the FTSE NSX Index Series provided a strong foundation for index-based strategies.

Key Milestones and Development

A major milestone occurred in 2014 when FTSE Group merged with Russell Investments’ index business to form FTSE Russell under the London Stock Exchange Group. This integration strengthened the capabilities behind the index, combining global expertise with deep analytical resources.

Over the years, the index has undergone continuous enhancements, including updates to selection criteria, weighting methodologies, and ESG considerations. These refinements ensure that the index remains aligned with evolving market conditions and investor expectations.

The index has also demonstrated resilience during periods of market stress, including global financial disruptions and the COVID-19 pandemic, reinforcing its credibility as a reliable benchmark.

FTSE Russell’s Legacy

The FTSE NSX Index Series is part of the broader ecosystem of indices developed by FTSE Russell. These indices collectively support trillions of dollars in assets and are widely used by investors worldwide.

Index Methodology and Construction

Core Principles

The methodology of the FTSE NSX Index Series is built on three fundamental principles: transparency, investability, and representativeness. These principles ensure that the index accurately reflects the Icelandic equity market while remaining practical for investors.

A rules-based approach governs all aspects of index construction. This eliminates subjectivity and ensures consistency in how the index is maintained over time.

Eligibility Universe

The index draws its eligible universe from the FTSE Global Equity Index Series. This ensures consistency with global standards while focusing specifically on Iceland.

To qualify, securities must meet criteria related to listing, market capitalisation, liquidity, and free float availability. These requirements ensure that only investable securities are included in the index.

Free Float Adjustment

The index uses a free float-adjusted market capitalisation methodology. This means that only shares available for public trading are considered when determining weights, improving the accuracy and investability of the index.

Constituent Selection and Screening

Selection Criteria

The FTSE NSX Index Series includes companies listed on Nasdaq Iceland that meet minimum thresholds for size and liquidity. This ensures that the index provides broad yet practical market coverage.

Screening Policies

Additional screening criteria may include governance standards and market accessibility requirements. ESG-focused variants are also available, allowing investors to align their portfolios with sustainability objectives.

Weighting and Rebalancing

Weighting Methodology

The index follows a free float-adjusted market capitalisation weighting system. Larger companies therefore have a greater influence on overall performance.

Rebalancing Process
