Press release – Trading Hours for Equities

Warsaw Stock Exchange (GPW)

In November 2019, the Association of Financial Markets in Europe (AFME), and the Investment Association (IA) called for European equity trading venues to review market opening hours across Europe.
Prior to even considering any changes to trading hours for equities, which could be
detrimental to European markets, a number of complex issues need to be thoroughly
examined to fully understand the effects any changes would have which includes:
• the needs of end investors;
• the interactions between different markets during the length of the trading day;
• the potential threat to liquidity;
• the cross jurisdictional impact across markets and linked products; and
• the competitiveness of the markets

These points alone suggest that a shortening of the European trading day could be a move
in the wrong direction and overall detrimental to European markets and end investors.
The Covid-19 crisis has shown that regulated markets are central in times of uncertainty
(high volatility and high traded volumes). Transparent, fair and resilient markets offer
management of risks and liquidity across global geographies with high integrity and are of
the utmost importance. From a liquidity perspective, it is important to underline that there
are currently no liquidity issues on European regulated markets, especially at the beginning
and at the end of the trading day, that would motivate a change of trading hours. The
amount of liquidity present on European markets in the early trading hours and during the
latter part of the afternoon demonstrates that the length of the trading day currently
reflects investors’ needs.
Shortening the trading hours of transparent lit exchange markets would further facilitate an
unlevel playing field since Systematic Internalisers (SIs) or OTC markets, which already
transact a large part of their business outside of exchanges’ main trading hours, would not
be subject to such a change.
An important issue raised is that of employee well-being. Given that SIs and OTC markets
already operate outside current exchange opening hours and that their trading desks are
therefore staffed to accommodate these markets and other asset classes, a shortening of
the European trading day would have no impact on employee well-being. Other measures at an enterprise level would be necessary to facilitate improved work-life balance (e.g.working in shifts, flexible working hours).
The negative impact on the interplay of markets and the economy in Europe has been left
aside in this debate. Consideration must be given to the enormous size of the markets and
economies affected, not forgetting the symbiotic relationship between trading hours and
the real economy. Given the challenge of recapitalising our economies due to the Covid-19
crisis, efficient, competitive, and well-functioning European markets are of paramount
importance to ensure our economies recover from the current crisis. As such, it is crucial
that they remain available for market participants according to their needs.

1. The length of the trading day in Europe caters to investors’ needs

The length of the trading day in Europe is designed to serve investors as well as issuers and to cater to their preferences and trading needs. Current trading hours in Europe allow
investors to manage their positions and risks over the day in very liquid, transparent and
efficient central limit order books. Equity markets operated by exchanges provide
concentration of addressable liquidity and transparent price formation throughout the
course of the trading day. The potential negative impact that a shortening of the trading
day could have on these two core functions cannot be overlooked.
The impact of a shortening of the trading day on exchanges’ price formation function should also be taken into consideration. Shortening trading hours would further increase the number of trades taking place away from the lit space since only trading venues are included in the scope of the proposal whilst SIs and OTC would not be impacted. This could, in turn, restrict the exchanges’ ability to act as a reference market and drive even more flow away from transparent markets which is something legislators already accept as an unintended outcome of MiFID II and are seeking to remedy in further amendments to the legislation. In such a scenario, investors would face both stale prices (no price formation) and higher costs (retail clients, for example, are exposed to wider spreads during markets’ off-hours) for longer periods. Shortening trading hours would also have an impact on the flow diversit as there would be less interaction between retail and institutional flow. This would be against the spirit of the CMU and go against the objective of stimulating an equity culture in European markets.

2. The length of the trading day in Europe provides for interaction with other markets

The evolution of the length of the trading day in Europe was conceived to facilitate investors’
needs and allow European markets to interact with other key markets in the US and Asia.
Some markets in Europe offer longer trading hours to allow for interaction with markets in
other jurisdictions. One of Europe’s advantages in this regard is that it is uniquely situated
to span both the Asian close and the US open. The reduction of trading hours in Europe would have an impact on this unique status and potentially offer competitive advantages to other jurisdictions to expand their trading hours to compensate for this new gap between market close in Asia and market opening in Europe. Such a decision would place European markets at a competitive disadvantage.
In addition, index and equity derivatives markets rely on price formation of the underlying
cash equity markets that are operated by exchanges. Shortening the trading day for equity
markets would translate into the loss of basis for index calculation and of the underlying
market for equity and index derivatives (on and off exchange) when trading venues are
closed. Similarly, corporate bonds markets and equity markets would not trade in a
synchronised manner.

3. Trading hours need to be able to reflect the diversity of various ecosystems

Throughout Europe, trading hours have been set and, in certain cases, adapted, to suit the
local ecosystem for a given market. Currently, there is a certain amount of divergence in
the trading hours observed across European exchanges with some trading days being shorter and some longer1. This stems from regional specificities and investor preferences. Trading hours need to be able to reflect these differences and accommodate local habits, time zones, retail activity and historical solutions with the aim of maintaining liquidity
distributions. Due to the demand of end investors to trade longer (and some FinTechs
intending to move to a 24/7 ability to trade financial assets) we have seen an extension of
evening trading hours in several local markets.
Trading hours that cater to regional specificities and preferences are vital to achieving the
objective of CMU, while still ensuring that the diversity of markets and investors in the EU
can be nurtured and prosper in the future.

4. The length of the trading day in Europe does not directly impact working hours

Whilst exchanges recognise the need to ensure the well-being of employees in the industry,
the length of the trading day, in itself, does not have a negative impact on the working
culture of trading. Moreover, trading desks today are already operating longer than exchange
equity trading hours for other asset classes and Systemic Internalisers and OTC trading. The claims of better work-life balance are based on the premise that narrowing the time frame in which stocks are traded on regulated markets would open the door to a better work-life balance in the industry. Exchanges would reject this premise and note that other measures would need to be deployed at an enterprise level to improve the well-being of employees.


This is a complex issue that warrants serious reflection in terms of the competitiveness of
Europe, market quality, depth of liquidity, the participation of investors in the market whilst
also recognising the need to ensure the well-being of employees. Given the considerations
outlined above, FESE believes current trading hours best serve the interest of investors and
that a shortening of the European trading day would be a move in the wrong direction and
detrimental to European markets.
