Introduction and Overview of the FTSE Long Short Index Series

The FTSE Long Short Index Series is a sophisticated benchmark designed to measure the performance of long-short equity strategies across global markets. Developed by FTSE Russell, a subsidiary of the London Stock Exchange Group, this index series plays a vital role in modern investment frameworks by enabling investors to capture both positive and negative market movements.

Unlike traditional long-only indices, which track the performance of equities that investors hold, the FTSE Long Short Index Series combines long positions in certain securities or factors with short positions in others. This structure allows the index to generate returns from both rising and falling markets, making it particularly relevant for hedge funds, institutional investors, and advanced portfolio strategies.

The index operates within a transparent and rules-based framework, ensuring that all aspects of construction, selection, and weighting are consistent and replicable. This approach enhances credibility and allows investors to use the index for benchmarking, product development, and performance evaluation.

As global financial markets have evolved, long-short strategies have gained prominence due to their ability to manage risk and enhance diversification. The FTSE Long Short Index Series has been developed to reflect this shift, offering a reliable and structured way to measure such strategies.

In the broader investment ecosystem, indices like this serve multiple purposes. They act as performance benchmarks, support the creation of passive investment products, and provide a foundation for research and portfolio construction. The FTSE Long Short Index Series fulfils all these roles while catering specifically to the needs of investors seeking exposure to long-short equity strategies.

Understanding this index requires both technical insight and practical context. Technically, it involves a structured methodology for combining long and short exposures. Practically, it serves as a critical tool for investors aiming to optimise returns while managing downside risks.

History and Evolution of the FTSE Long Short Index Series

Origins and Development

The FTSE Long Short Index Series was introduced in response to growing demand for transparent benchmarks that capture the dynamics of long-short investment strategies.
