Options Exchanges and Order Flow

Image result for Andy Nybo

In the TabbFORUM, a web platform for discussion of the capital markets by informed participants therein, I see a new piece by Andy Nybo about the segmenting of the order flow in the U.S. listed options markets.

Nybo is head of derivatives research for the TABB Group, where he has worked for 10 years. So he knows all its mysteries, such as presumably why the capitalization convention for the TABB Group is reversed for the name of the TabbFORUM.

His article begins with the observation that there are lots of US options markets, and that they try to compete with one another with various innovations. Isn't that a good thing? Well ... it depends on the innovation. He complains that one new trend is raising havoc, "price improvement auctions."

He defines a price improvement auction as "a trading protocol that allows market makers to improve prices for a segmented swatch of order flow," and claims it has a "number of detrimental consequences."

In essence the market maker (an exchange member) submits a two-sided offer -- that is, both a buy and a sell price -- into the market looking for takers. If there ARE takers, then this is by definition and for them an improvement on the quoted market price. Otherwise they would have bought (or sold) at the quoted market price.

This bifurcates the market and, in Nybo's view, it has contributed "to a steady decline in the long-term health of US listed options markets."  The so-called "lit" market is stripped of its "most valuable retail flow."

Nybo doesn't suggest a solution, though. In fact he ends with a warning that "solutions often have unintended consequences themselves."

That's an odd way to end the piece but, hey, who am I to question Nybo's literary talents?

The discussion confirms my general sense that huge changes in the business of financing business lie just ahead. The next five years or so will see an explosion of new technologies in the field, along with the playing-out of old institutions that are of as much continuing use and vitality as a physical trading floor in the 21st century.

Huge. I said it.

England as a Raft?

In a lecture delivered in 1880, William James asked rhetorically, "Would England ... be the drifting raft she is now in European affairs if a Frederic the Great had inherited her throne instead of a Victoria, and if Messrs Bentham, Mill, Cobden, and Bright had all been born in Prussia?"

Beneath that, in a collection of such lectures later published under James' direction, was placed the footnote, "The reader will remember when this was written."

The suggestion of the bit about Bentham, Mill, etc. is that the utilitarians as a school helped render England ineffective as a European power, a drifting raft.

The footnote was added in 1897. So either James is suggesting that the baleful influence of Bentham, Mill etc wore off in the meantime or that he had over-estimated it.

Let's unpack this a bit.  What was happening in the period before 1880 that made England seem a drifting raft in European affairs, to a friendly though foreign observer (to the older brother…

Cancer Breakthrough

Hopeful news in recent days about an old and dear desideratum: a cure for cancer. Or at least for a cancer, and a nasty one at that.

The news comes about because investors in GlaxoSmithKline are greedy for profits, and has already inspired a bit of deregulation to boot. 

The FDA has paved the road for a speedy review of a new BCMA drug for multiple myeloma, essentially cancer of the bone marrow. This means that the US govt has removed some of the hurdles that would otherwise (by decision of the same govt) face a company trying to proceed with these trials expeditiously. 

This has been done because the Phase I clinical trial results have been very promising. The report I've seen indicates that details of these results will be shared with the world on Dec. 11 at the annual meeting of the American Society of Hematology. 

The European Medicines Agency has also given priority treatment to the drug in question. 

GSK's website identifies the drug at issue as "GSK2857916," althou…

Francesco Orsi

I thought briefly that I had found a contemporary philosopher whose views on ethics and meta-ethics checked all four key boxes. An ally all down the line.

The four, as regular readers of this blog may remember, are: cognitivism, intuitionism, consequentialism, pluralism. These represent the views that, respectively: some ethical judgments constitute knowledge; one important source for this knowledge consists of quasi-sensory non-inferential primary recognitions ("intuitions"); the right is logically dependent upon the good; and there exists an irreducible plurality of good.

Francesco Orsi seemed to believe all of these propositions. Here's his website and a link to one relevant paper:

What was better: Orsi is a young man. Born in 1980. A damned child! Has no memories of the age of disco!

So I emailed him asking if I was right that he believed all of those things. His answer: three out of …
