New Real Time European Market Benchmarks


The largest pan-European stock exchange, Bats Europe (Bats), has introduced Bats Indices — real-time, high-quality alternatives to commonly used indices whose values are often delayed by 15 minutes.

Bats Indices have changed the way investors see the market allowing them to track market movements as they happen, better informing trading and investment decisions.


The Difference


  • Real-Time Index Values– Most market tracking indices are shown to individual investors with a 15-minute delay.
  • High Quality, Pan-European Data –  All of the Bats Indices are calculated using data based on the trading taking place on its exchange with the exception of the Bats UK Alternative 100 which uses ISDX data.
  • Simplifying Cost and Licensing – Bats has committed to significantly lower license costs with capped fee increases and extends rights to affiliates, trustees, custodians and clients.
  • Robust, Trusted, Regulated – Bats is a stock exchange regulated by the UK’s Financial Conduct Authority (FCA) with a proven commitment to improving markets.
  • Transparency – Unlike some other index providers, Bats publishes the licence agreements, fees and rules and calculation methodology behind its indices.
  • Consistency – All Bats indices are created with the same methodology allowing comparable benchmarks across sectors, between large and small cap, and as other indices are introduced, markets and regions.

What is an Index?



An index is group of stocks designed to reflect the performance of a market, or a portion of a market (e.g. an industry sector).

When first established, an index can start at any value. Investors track the change in the value to see market movements rather than the value itself.

An index is generally comprised of a portion of the overall universe of stocks in a geography, business sector or other grouping.  Commonly referred to as “benchmarks” the index reflects a market’s performance.

Indices are typically named to reflect the:

  • Index creator/owner
  • Specialisation (geography, business sector, grouping)
  • Number of stocks in the index, e.g. Bats UK 100 index


Mathematics and Methodology Behind an Index



The methodology for calculating an index varies and is proprietary to each index creator/owner. A number of rules are required to ensure the index value is only affected by the change in the value of the individual stocks.

For instance, the performance of larger companies has a greater impact on the value of a market capitalisation weighted index than smaller companies.


Index Rebalance



An index is reviewed on a regular basis to ensure it remains representative of the relevant market.  Upon review, known as a rebalance, constituents can be removed and replaced by companies that better reflect the overall market.

The frequency of rebalances varies by index, whilst all are rebalanced on an annual basis, many are also rebalanced on a quarterly basis.


Component CompaniesIndEd4


A company is considered eligible to be an index constituent if it meets the criteria stipulated in the index’s rules.

Such criteria can require the company to have a minimum market capitalisation, to have listed a minimum percentage of its shares (its free float), and to possess a minimum level of trading liquidity.

Bats Challenges FTSE Monopoly and Redefines the Market


Bats Europe, the region’s largest stock exchange operator has launched a series of UK-focused benchmark indices that will revolutionise investors’ view of the market, improve transparency and drive down costs; after 32 years FTSE has some serious and credible competition.

Bats Europe is a division of the Kansas City-based Bats Global Markets exchange group, and it has developed the indices in consultation with ‘incredibly frustrated’ investors and index users to deliver a ‘robust and trustworthy’ alternative to the incumbent.




Bats aims to break FTSE’s monopoly of the market by delivering ‘aggressively’ priced indices ‘with a long term commitment to materially reducing costs for all investors’.

With the industry committed to transparency post-RDR and increasingly focussed on reducing costs at a time of low investment returns, FTSE angered many in 2012/13 when it hiked the cost of data licences and reduced flexibility for licensees.

The ire generated is palpable in a CityWire headline that appeared at the time: ‘FTSE Licence Hike Fury: What are the Alternatives?’ Another described wealth managers as ‘seething’.

After numerous requests from investors and index users, Bats designed an alternative in consultation with the industry and its commitment to reduce costs has struck a chord with wealth managers, retail stockbrokers, media channels and investors alike; ultimately, higher data fees percolate through to the investor, creating a headwind for investment performance which is completely counter intuitive to those seeking to drive down costs and democratise investing

  • Have simplified licensing arrangements and a commitment to materially reduce costs
  • Be highly correlated with comparable benchmarks to accurately reflect market moves
