The new Trading InfoSnack article Back to the Future(s) points out how a dislocation between cash and futures markets demonstrates how a market structure change – such as an outage – in one market can have wider ramifications in the securities trading ecosystem.

The article looks at the significant distortion caused by an outage in the market for Swiss Equity Futures on 14 April 2020 to probe the interdependencies between cash and futures markets in equities and delta-one securities. Comparing the average spreads and depth at BBO for SMI equities and for two highly liquid SMI ETFs for which there are corresponding futures contracts allows for several interesting observations.

A previous Trading InfoSnack, What’s in a Liquidity Smile?, used that same event to provide insight into how the shape of the liquidity smile evolves over time and is influenced by different trading models and market events.

Insights on Relevant Trading and Market Structure Topics
The Trading InfoSnack articles are brief but insightful research features that provide commentary on market relevant trends, models and microstructure that influence the trading of Swiss securities, underpinned by in-depth analysis from the Equities team of the Swiss Stock Exchange.

Whilst the specific focus of Trading InfoSnacks is on the trading of Swiss securities, the approaches and perspectives constructed also have more broad application across the EU securities trading landscape. The articles are therefore of interest to trading and market structure professionals with a focus on the EMEA region.
