Poof! Legendary Ronin Capital Disappears (UPDATED)

“If it be now, tis not to come, if it be not to come, it will be now; if it be not now, yet it will come. The readiness is all." - Shakespeare: Hamlet Act 5, Scene 2   UPDATE HERE (3/26/2020) Last Friday, March 20, CNBC was first to report that "one of the CME’s direct clearing firms was unable to meet its capital requirements. The move forced the exchange to step in and invoke its emergency protocols to auction off the portfolios. Ronin Capital, based in Chicago, was confirmed to be the firm in question, according to sources. Additional sources said Ronin’s problems stemmed from positions in futures tied to the CBOE Volatility Index (VIX)." In concert with Alphacution's recent feed post, "Marketquake: The Volatility of Volatility," on unprecedented volatility levels that surpass that of the 2008-2009 Global Financial Crisis (GFC) period, I wanted to assemble whatever we could on Ronin. A story not well known outside of Chicago prop trading circles, John S. Stafford, Jr. - the founder of [...]

A Flock of Canaries: From Allston to XTX

"You don’t lead by pointing and telling people some place to go. You lead by going to that place and making a case." - Ken Kesey   If you believe - as we do - that everything is connected to everything else, then it stands to reason that all events have potential to be seen as the proverbial canary in the coal mine. Therefore, what we really need to do is notice stuff and connect dots. Here's a few of our latest observations... On February 10, 2020, Bloomberg reported "high-frequency firm Allston cuts employees amid low volatility," and further noted that this move follows XR Trading's 10% headcount reduction in late 2019. This got us thinking about the tier of smaller to mid-sized proprietary trading firms and if any of the available data (which currently tends to be US equities-centric) provide clues as to the health of those firms - as well as that space in the market ecosystem (where prop firms and market makers reside) that we typically call [...]

Virtu Financial: More Acquisitions on the Way, If…

When we launched our first trading program at Quantlab in the late 90's, we didn't have direct market access yet. We generated an order list (overnight) that was worked throughout the subsequent market session at the discretion of an algo-equipped executing broker; some of whom now roam the halls at Jefferies / Leucadia. This was the era when 1- to 3-day portfolio turnover was considered fast - SOES bandits were still a thing - and Schwab would soon acquire electronic trading pioneer, CyBerCorp, from Philip Berber - a short drive down the road from our Houston headquarters in Austin, TX. Of course, everyone had nicknames then - as I suspect they still do now. Ed Bosarge, founder of what eventually became Quantlab (after at least 3 prior related incarnations that began for me around 1996), was known as Dr. Evil. Let's just say it's a hair-raising story about a swashbuckling pioneer of applied math involving a hideous toupee... I was known as Mr. Bigglesworth - or, "Bigsy" for short. No [...]
