Is the fun about to come to an end for those trying to optimise (and capitalise on) their interaction with one of the most heavily traded equities in Europe? It has to be one of our favourite stocks for the complexity it presents for equity exposure to a single organisation. Two different lines of stock, both traded heavily on two primary exchanges. Competition aplenty from the UK and European MTFs and the full spectrum of market mechanisms accessible to trade; lit, dark, auctions, off-book (on-exchange), OTC….the list goes on. It presents a challenge for many investors, banks and brokers and a long standing opportunity for the canny arbitrageur.
On the back of the announcement of our partnership with ETFbook yesterday, we’re pleased to provide investors with our first weekly summary report of transparency in European ETPs, by consolidating all issued products and their liquidity across the fragmented landscape. These updates are for product issuers to monitor the evolving European ETP landscape, for market makers to gain an insight into primary and secondary market liquidity, and for buy-side investors to see new investment opportunities.
The summer saw increased nervousness in the European markets in reaction to a fragile recovery from the pandemic and concerns about the spectre of inflation. However, trading in equities remained quite buoyant, especially in September, and Q3 volumes returned to their seasonal, pre-pandemic average, in contrast to last summer’s record breaking doldrums. Welcome to our latest quarterly survey of market volumes and fragmentation trends in European equities. If you are unfamiliar with the topic, we encourage you to visit our website to read our Microbites series for an explanation of European market microstructure.
Do some traders have an advantage over others… and does it matter? How fast are equity markets? Or how much of the market operates at high speed? big xyt took an electron microscope to our normalised market data to find out. We analysed UK lit markets to measure the time between a trade and the last relevant orderbook change. The FCA established 500μs as a speed benchmark in their latency races paper. This is 200x faster than the 1/10 of a second after the gun in which a sprinter can false start.
There is a difference between what people say and what they do. Companies are realising the importance of actions speaking louder than words and are beginning to focus on changing behaviours not just the “Values” statement on their website. Investments are no different as can be seen in our analysis today. Investment in companies with strong Environmental, Social and Governance (ESG) mandates are already being grouped together by ETF issuers to facilitate easier investment in ready-made portfolios of socially responsible companies.
Welcome to our latest quarterly survey of market volumes and fragmentation trends in European equities. If you are unfamiliar with the topic, we encourage you to visit our website to read our Microbites series for an explanation of European market microstructure. With the major European indexes enjoying substantial price gains in H1 2021, we might have expected a similar boost in market volume. However the quarter just finished was the weakest Q2 in over four years. In this edition of the survey we have added a view of the ETF market, which by contrast has grown in volume terms by 6.5% versus 2020, albeit on a cross-asset basis.
As a trailer for our forthcoming Q2 2021 survey of European equity market microstructure, we thought you might like a sneak peek at what’s been happening to fragmentation. Following Brexit and the divergence of dark trading rules, we have been monitoring the trend in the UK. The graph below shows the UK250 index where on-order book ‘lit continuous’ trading has reached a 5-year low in terms of the daily market share traded in June at just 28.5%, while auction market share is a whisker under the previous record high in December at 22.7%. Meanwhile, dark trading has risen to over 12% from 9% prior to October 2020.
We have just launched the Market Microstructure in Practice for Equities with big xyt’s API interactive presentation on the big xyt Academy. If you are a quantitative analyst or developer, trader, portfolio manager, or anyone interested in market microstructure for sales and marketing, this could be of interest to you. Explore big xyt’s powerful and flexible API to see how convenient and reliable it is for conducting research and analysing market microstructure, as well as assessing trading performance and algos.
In the search for liquidity, particularly whilst minimising market impact, a means to identify large trades and where they take place is key for the investing community. The regulatory changes in MiFIDII introduced the concept of Large In Scale (LIS). No, not not a post-Brexit way to limit fishing quotas, rather a means to identify large transactions in financial instruments. In the equity landscape this has resulted in some confusion post-Brexit. Depending on the activity in each individual stock, an LIS threshold was set, above which the trade could be classed as a block trade. As Broker Crossing Networks were abolished at the same time, this LIS threshold was applied as one of the permissible justifications of many venues supporting dark trading.
We’re not too sure what all the excitement is about… at big xyt we have been researching the changing shape of the dark landscape for years. In fact, rather like long established theories, on the face of it European dark trading volumes have remained relatively steady. Our team of curious data scientists likes to help the trading community to explore a bit deeper and it’s easy to see that Pan-European dark volumes have been in a fairly tight range with around 8% share of adjusted (our proxy for addressable volumes) for some time, only getting squeezed temporarily with the onset of double volume caps in mid 2018.
