Susquehanna Securities and the Hidden Stat Arb Strategy

"The mind is not a vessel to be filled but a fire to be kindled.."Plutarch The comment has been made here before, likely more than once: As we go along the path of our research, our ability to see - to interpret the data, and the shapes that are formed from that data - tends to improve. This is not only true of newer shapes forged from amalgamations of newer data - and additional sources - but of older shapes, as well. Recently, I stumbled over a series of charts first published in July 2019 in the Feed post, "Ranking Strategy Speed for Top Quants, Market Makers," which remains among our more fascinating discoveries. Therein, we compared average stock position sizing for a list of notable trading and hedge fund firms, from Renaissance Technologies (RenTech), D. E. Shaw, and Two Sigma to Jane Street, Hudson River Trading (HRT), and Tower Research Capital (TRC). Citadel Securities and Susquehanna Securities were in the mix, as well. The rankings were roughly delineated between [...]

Cheap Volatility: A Lesson In Market Structure Mechanics

"The world breaks everyone, and afterward, some are strong at the broken places." - Ernest Hemingway   Alphacution has always been fascinated by the players. Unlike the world of sport, market players have unique potential to influence the field of play, and thus create a feedback loop that influences other players, and so on causing market ecosystem evolution. In this game, the rulemakers and overseers - the referees - are typically playing catch up... This is not to suggest that markets don't have naturally occurring limits in addition to those that are imposed by referees. They do. There are always capacity constraints, given performance requirements and performance expectations; and so, we are further fascinated by how players navigate - how they survive, thrive and scale (or not) - relative to the inevitability of market limitations, many of which are currently not well understood. Throughout these digital pages, Alphacution has plotted a journey to fill this unmet need for understanding -  presenting the output of our fascinations - the stories of [...]
