The vast majority of the equities market trades electronically while the bond market is still in its infancy by comparison, but MarketAxess is seeking to change that. 

Recently, we hosted a virtual event with the MarketAxess team where they explained how they were solving challenges in the world’s largest bond marketplace while leveraging AI and the cloud. See below some of the key takeaways of the session (you can also check out the recording of the panel here). 

What does MarketAxess do?

MarketAxess is the operator of a leading electronic trading platform for fixed-income securities and the provider of market data and post-trade services for the global fixed-income markets. 

Julien Alexandre, Co-Head of Research at MarketAxess, explains how they electronified the trading process.   

”MarketAxess came about 20 years ago, and it electronified the [trading] process. You can submit a request for a quote instead of calling many people at different times. Now, you just send a request electronically, get prices back, and have access to bigger leverage by doing that because more people can provide you with more quotes in a lesser amount of time.” 

Julien explains the comparison of the bond market vs the stock market.

How has MarketAxess worked with

Over the past five years, has partnered with MarketAxess in building their Composite+ product.  

Composite+ is powered by H2O open source is a platform that delivers greater insight and price discovery in real-time, globally, for over 24,000 corporate bonds. Composite+ has won several awards for its use of AI, including the Risk Markets Technology Award for Electronic Trading Support Product of the Year and the Waters Technology American Financial Technology Award for Best Artificial Intelligence Technology Initiative.  

Julien further describes the two reasons why Composite+ was successful. 

Reason #1 – Partnership with H2O

“The first one is the ability that we had to model the problem the right way. And that’s where H2O was very helpful to us when we engaged five years ago with your expertise and versatility in dealing with machine learning programs across many different sectors and many different applications. So being able to properly set the model and work on feature building and feature creation and was instrumental to the success of Composite+.” 

Reason #2 – Unique Data

Julien continues, “The second reason is the unique data that MarketAxess has through its trading platform and really it’s a virtuous circle where we get liquidity on the platform and we’re able to use the information we have access to from the platform and repackage it into Composite+ into a precise pricing algorithm that then makes its way back into the platform by helping with data and the new protocols and new ways of trading that, have been built over the last few years.” 

What was MarketAxess’ journey to the cloud?

Liz Brand, Global Cloud Engineering Manager, speaks to their journey into the cloud and how innovation was the true driving force on adopting the cloud at MarketAxess. She started the conversation with a few reflective questions.  

“When we looked at the cloud, we asked ourselves, how can we create environments that are focused on innovation? How can we do that dynamically and support our entire company? How would this allow people to experiment with new technologies and work with integrating them into our applications at a larger scale?” 

Further, she delves into the key things that were important to their team when evaluating the cloud: 

  1. Cost – the ability to scale their workloads without running 24×7 and saving money.
  2. Velocity – speed to market.
  3. Customer obsession – obtaining feedback and acting on it quickly. 

The event continued with multiple questions coming from the global audience (26 counties in attendance to be exact). One of them sparked the team’s interest in working at MarketAxess.  

What’s the day-to-day like working at MarketAxess?

The MarketAxess team has a beautiful office in Hudson Yards occupying three floors of 55 Hudson Yards (which hopefully I’ll get to visit at some point), as well as offices all around the world. There’s a focus on collaboration in their office locations, with an open floor plan and many different spaces, both formal and informal, for employees to gather. Creativity is at the core of what inspires MarketAxess employees to do their best work, and their NYC office space is no exception: they’ve commissioned a number of artists to produce murals and other works of art throughout. There is also a cafeteria where employees can pick up their company-provided lunch or snacks and eat together while enjoying views of the Hudson River.

Liz explained the close-knit, collaborative team when she came into the office, “I think the greatest benefit of having desks and being around each other is you would overhear conversations. We’re not a massive company. People know each other really well.”

While physically being in the office provides unique benefits and MarketAxess has designed an employee-centric environment, the pandemic has given MarketAxess the opportunity to entirely rethink its approach to hybrid working. They now offer a high degree of flexibility to their tech employees, as far as choosing the work environment that best suits them – something their people greatly value.
