Virtu’s, Flow Trader’s Optionality? Not So Much…

“Research is what I’m doing when I don’t know what I’m doing.” – Wernher von Braun

In the hierarchy of preferred trade types, the riskless trade sits at the top. Capturing a perfectly hedged spread or pricing anamoly, or performing a round turn across the spread and back to flat in some temporal duration measured in micro- or even nanoseconds are examples of riskless trades. Like poker’s rare royal flush hand, a mechanism to persistently discover and then capture ~riskless trades is the most coveted of the trading world.

What comes next in this hierarchy is the directionless trade, where the trader essentially plays both sides of the trade and where success is achieved whether the target ultimately wins or loses. Like poker’s next-in-line straight flush hand, the key caveat to the directionless trade is the requirement that the price of the target moves; that there is enough volatility during the life of the trade to cover the cost of entering and maintaining that trade.

It is here that we need to pause and focus for today’s instructive tale involving our good friends at Virtu Financial and Flow Traders – as well as the implications this story might have for others that also travel in this neck of the woods:

In the early days of the derivatives markets, the application of option pricing theory was not universally distributed to say the least. A short list of players had mastered – and automated – the mathematics (and mechanics) of pricing and trading options far more than the bulk of those early market participants. As such, riskless conversion and reversal strategies could be employed almost at will to exploit pricing disparities – and harvest monstrously enviable profits.

In time, this kind of edge decayed – and these formerly riskless strategies started to grow risks, sometimes known as delta legs. In turn, these new delta exposures gave birth to fundamental research departments in what was formerly among the very first quant shops. (It was here that I serendipitously stubbed my toe and fell unwittingly into this bizarre business…)

Now, without venturing too deeply into the weeds from here, the way a derivatives trading firm industrializes its edge and scales its book, in particular, is by aligning an increasing roster of positions in such a way that the aggregate deltas form a straddle – like a huge “smile.” And, even though there will be offsetting (short theta) positions to neutralize the cost of the “portfolio straddle,” the net bias of the book should be long puts, calls and theta – which is the rate at which the value of an option decays.

It is here that we finally identify one of the key challenges of managing a large options book that is managed to protect against fat tail events: paying for the daily cost of theta. Back in the day, we used to “pay” for theta with short term trading ideas, usually around fundamental catalysts like FDA meetings for new drug trials and, of course, earnings announcement dates.

Due to the manual nature of devising these kinds of trade ideas, this component of the broader strategy was difficult to scale. If only there had been an automated trading mechanism that made money everyday that could cover the cost of theta in the options book. Hmmm, if only… (Do you see where I’m going with this?)

Here’s the problem (and, potentially, the opportunity) depending on where you sit at this poker table, and given the cards that you currently hold in your hand:

If you are paying close enough attention at home, recall the concept, metastrategy of nested alphas, from the recent piece on DRW.  Yes, it’s a mouthful, but what it suggests is the idea of two or more complementary or self-reinforcing strategies that are designed, in part, to minimize costs, enhance performance, or both. (The “dark pool” craze among the leading broker-dealer banks and others is symbolic of this “nested metastrategy” concept.)

Among leading market makers, there is a subset that trade options as a core component of their trading strategies and another subset that does not (with the possible exception of portfolio hedging, as you will see shortly). Virtu and Flow Traders are among the latter group. In the case of Flow Traders, 28 quarters of 13F filings and precisely zero options positions were reported, so there are no charts to share on that score.

Virtu, on the other hand, has taken a very different path towards minimal use of options (and that is as a very recent portfolio hedge). The odd thing is that they have acquired companies that were steeped in options. When we look at our modeling of the Knight and GETCO lineages of 13F reporting, we see significant use of options – typically greater than 30% or 40% of 13F portfolio value – up until the point they get folded under the Virtu umbrella.

In the first chart below, Alphacution presents the Knight, GETCO and Virtu lineages of the portion of 13F portfolio values represented by options:

First, take note of the small detail that Virtu has submitted its 13F report for Q4 2018 as of Jan 16, 2019 – almost a month early from previous years when most prop-oriented firms would take full advantage of the 45-day post-quarter-ending window available to disclose these positions. Now, notice that with the exception of the dramatic and unprecedented spike in allocation of 13F portfolio value to options by the end of 2018 (35.5%), Virtu’s allocation to options over the previous 36 quarterly reports had never exceeded 11.4% (and had averaged 2.2%). Why the spike in usage now?

Lastly, what’s potentially more interesting here is that 35.5% of 13F portfolio value for Q4 2018 is made up of just 9 positions – 4 puts and 5 calls – 6 of which are among the 10 largest positions and each of these on broad market ETFs. In other words, this option penetration represents 0.5% of a total 1,673 positions for this latest quarter; a strategy that has persisted for all 3 lineages for the 12 quarters beginning Q1 2016, see below:

So, the unprecedented shift in portfolio hedge strategy just in the last several weeks notwithstanding, our concern is that the (very few) players that incorporate market making or high-performance trading in options and their underlyings are in a stronger position to be more aggressive and to cross more spreads than those who are singularly focused on positions in the cash markets. Not to mix our metaphors with the poker game we started at the outset, but this is somewhat like the difference between playing checkers and chess – or to be a bit more generous, chess and 3-dimensional chess.

One game is linear and the other has curves, and those that are fluent in the world of curves tend to be in a stronger position mathematically and mechanically.

Finally, if you think we’re picking on anybody – or, rooting against anyone’s success – you’d be seriously mistaken. These markets need more players and more diversity of strategy and positioning, not less. If one or two dominant players squeeze everyone else out of this critical segment of the markets – an area Alphacution has been calling the structural alpha zone – it is not good for the overall health of the markets…

Alphacution is being developed to help provide intelligence in an arena where few are accustomed to needing it, and fewer are accustomed to asking for it. Based on our analysis, this dynamic is about to change…

Alphacution is in the intelligence business.

We are uniquely focused on harvesting, packaging and distributing intelligence about the impacts of technology in financial markets and on the businesses of trading, asset management and banking. Our growing model library is our intelligence asset. Today, this intelligence asset primarily supports written research content, which can be accessed via standardized subscriptions and customized engagements. Occasionally, this core asset also supports video, audio and live presentation content. In time, Alphacution’s intelligence asset will support a broader platform of products and services, like data feeds and software.

For the past year or so, Alphacution has been publishing most of its research content on its Feed for free, and promoting that content via periodic newsletter. The purpose of this strategy has been to assess the interest in and demand for a unique perspective and a new level of intelligence on the financial markets ecosystem.

And, based on the growth in network and activity around that research, it seems that we have struck a cord with many of you – a network of senior executives representing some of the most advanced players in the global financial markets arena and their stakeholders.

The recent trajectory of pageview metrics on our site is symbolic of this claim, as shown below:

Now it’s time to take that level of engagement and direct it towards a more viable long term economic support model that ultimately allows us to scale our team and enhance the quantity and quality of our intelligence.

So, here’s what we are going to do about that:

For those of you who are eager to derive greater value from this work and apply that intelligence to your own business interests, Alphacution is offering individual introductory subscription options priced at $275 per year or $25 per month, cancellable at any time. Both of these options include a rebate on purchases of deeper, more substantive reports and case studies.

In other words, the entire value of an individual subscription paid up to the point of purchasing a single report will be deducted from the purchase of that report. (Rebates not to exceed the maximum value of an annual subscription.)

Examples of upcoming reports – that fall within our 2019 research strategy, outlined in the post Alphacution’s Book: Not Hiding, In Plain Sight – that will be available via the aforementioned subscription rebate mechanism include:

  1. Case Study: Citadel, LLC (~ Q1-2019)
  2. Case Study: All-Time Top 10 Hedge Fund Managers, Ranked by Profits (~ Q2-2019)
  3. Case Study: Top Proprietary Trading Firms (~ Q3-2019)
  4. Case Study: Goldman Sachs Group, Inc. (~ Q4-2019)

Enterprise subscription packages and custom content/service engagement options are available upon request at

Now, for those of you who don’t expect to take advantage of the offers outlined above but want to continue to enjoy the insights, intelligence and occassional entertainment that remain openly available on the Feed, I want to make this specific plea:

Free doesn’t mean there are no costs. In fact, in this case, there have been extraordinary costs in the accumulation of experience and sight, meticulous curation and assembly of data, and creative visualization of and storytelling around our findings.

So, if you value quality content – here or anywhere else – then you need to find a way to support that content at some level simply because you want it to continue to exist. Our post, In Support of Digital Content – which was adapted from other notable digital era content developers – makes a more expansive case for this perspective.

Bottom line: Your efforts to support via one-time or recurring contributions will help guard against this content needing to move from the currently preferred audience-driven model (for its level of independence) to a sponsorship-driven model (which can be found on most other industry media outlets).

So, if none of the subscription options suit you, one-time and recurring support contributions can be made at any level here:

Of course, as always: If you value this work, please continue to “like it,” share it, comment on it – or discuss amongst your colleagues – and then send us

As our “feedback loop” becomes more vibrant – given input from clients and other members of our network, especially around new questions to be answered – the value of this work will accelerate.

Don’t be shy…
