There are two ways to figure out this safety to profit relationship. One is w/probabilities - you can list all the potential ways & places a gator can bite you, model the most likely of these, & buy armor to protect against those outcomes.

OR, you can approach it more precisely. You can study everything there is to know about the gator - its jaw size, hunger level, muscle strength, even mood & personality. You can know so much about your inventory that you can predict EXACTLY when & where that gator will bite.

Okay, time to explain the metaphor: Obviously, Flow Traders is the market maker. Market hedges are the expensive armor. ETFs are the gator. Re-read the above thread with these roles in mind.

Market making is about managing risky & unpredictable inventory. Many MMs hegdge to protect themselves, but hedging against every outcome is too expensive. Most MMs use stochastic models to hedge efficiently - they list a range of outcomes & hedge against the most likely ones.

Flow Traders is not most MMs. They hedge using deterministic modeling - they model ONE possible outcome and hedge against that outcome. They predict EXACTLY when the gator will bite.

This way of market making has its advantages, mainly via cheaper, more efficient hedges. But the downside is stark - if their model or research is even slightly off, they protected against the wrong outcome & can lose big. How can a business survive this way?

Using deterministic modeling, Flow boasts a near spotless market making record. At one point in 2017 they had made it 34 straight months without a single losing day. They made nearly $1 billion in 2020 trading the global ETF markets with impressive efficacy:pic.twitter.com/LLOQVazbZg

Deterministic modeling reminds me of a great
@TrevMcKendrick post on the science of magic tricks. What looks like magic is really just a glamorous recital of extremely hard work. Flow's precise predictive model isn't magic - it's tedious iteration. https://jacobian.org/2021/apr/7/embrace-the-grind/ …pic.twitter.com/y6ivetBLPS

The way Flow Traders makes markets isn't the only unique & insane part of their story. I'll be doing a much deeper dive into Flow's origins, business & future as a public company in an upcoming post. Sign up below if interested:https://frontmonth.substack.com/
