The Crypto Train: Citadel Securities Succumbs to FOMO

A first-of-its-kind outside investment from Silicon Valley venture heavyweights into Citadel Securities is a significant event, particularly for possible future competitors in crypto markets. But, the transaction itself didn't need to be exposed. So, why was it? Was this news or strategic communications? Alphacution weighs in...

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 [...]

“We” Were Wrong About Jane Street

"Two wrongs may not make a right, but a thousand wrongs make a writer." - Dennis Miller "If you're not making mistakes, then you're not doing anything." - John Wooden   In my last in-person meeting of the B.C. (Before Coronavirus) era, a noted Chicago hedge-fund-slash-market-making C-suiter told me: "You're just making this stuff up..." Answer: "Well, yes - yes I am. Based on an interpretation of an assembly of data supplied by you - and others..." There is no roadmap here, other than the one that is constantly being course-corrected in my head. No textbook. No lexicon. No Ivy League curricula to provide structure or Council of Elders to guide. Just the kind of seemingly unending puzzle-solving exercise to soothe a delusional level of puzzle-solving desire... And, the feedback loop supplied by you - Feed readers, subscribers and clients, alike - that informs a faint sense of navigation. With that, "we" are just making stuff up: Inventing language and pictures - and the stories that seem to fit well [...]

Gearing up for Jane Street

“Two roads diverged in a wood, and I—I took the one less traveled by, And that has made all the difference.” - Robert Frost   Jane Street is one of the most exciting players among the roster of proprietary market making firms in the entire trading ecosystem. What began in 2000 as Henry Capital, with memberships on the American Stock Exchange and Midwest Stock Exchange, today sports a broad global footprint and continues to solidify its legendary status among those that trade for their own account. As such, Jane Street is the subject of our next comprehensive case study to be published in the coming weeks. This post is an appetizer for that... Until next time...
