400ms of insider information

High frequency (insider) trading.

Nanex Research has found what looks like insider trading in the natural gas market prior to the release of the US Energy Information Administration's natural gas report. The quirk is that that insider trading happened just 400 milliseconds before the report was released:

On January 31, 2013, approximately 400 milliseconds before the official release of the EIA Natural Gas Report, trading activity exploded in Natural Gas Futures and ETFs such as UGZ, UNG and BOIL. Now that the Feds have stated (as claimed by a recent WSJ article) that they don't think there is merit in prosecuting people who get news information earlier than others by milliseconds, is it any wonder?

It is worth pointing out that the EIA Natural Gas Report comes out weekly (every Thursday at 10:30) and the market reacts within a few milliseconds. This is because the report centers on one number which makes it easy for machines to process and take action.

As Nanex points out, a recent SEC investigation into whether some news organisations gave investors access to economic data "a fraction of a second before the official release time" resulted in no charges being brought. At the time, it was speculated that there were two reasons for that: the first being that such a prosecution would stretch the definition of insider trading, and the second being that it was difficult to conceive of such a head start leading to any measurable advantage.

Insider trading is typically defined as acting on information which has not yet been made public (the legal definitions are far more complex than that, but that's largely owing to the byzantine nature of financial regulation). The problem with prosecuting news organisations for that is that typically, information hitting the newswires is the definition of it being made public. This has caused problems before: last year, Netflix's CEO faced trouble from the regulators for announcing on his Facebook page that the company had had over a billion cumulative viewing hours in one month. Facebook is not, apparently, "public" enough for the SEC.

If one of the newswires publishes information a fraction of a second before the others, that might constitute a broken embargo, or an undesirable leak; but it probably doesn't constitute insider trading, because the very act of publishing made formerly private information public (even the etymology's the same! "Publish" literally means "to make public").

But the second argument was that, in the seconds leading up to a potentially market-moving data release, trading slowed down and waited for the news. After all, there's no one — not even an algorithm — which isn't going to think a trade a fraction of a second before a data release offered at a markedly different price isn't a tiny bit suspicious.

That argument might not hold as much water if Nanex's data is accurate, though. It shows a definite collapse in the price of a natural gas exchange-traded fund (ETF) over the course of a hundred milliseconds. A fall of one per cent — even one which is then followed by an even greater fall once the actual data is released — is not to be sniffed at.

It's not clear who the counterparties in these trades were — who, that is, was convinced to make trades milliseconds before a major data release — but it's pretty likely that they were also algobots. Insofar as this represents a transfer of income from one set of computer-owners to another set, it's not the most concerning news. But it does raise further questions about how the market for information is shaped in the near future, and whether the simple dichotomy between public and not public information can hold up in that new world.

Let's face it: supporting Spurs is basically a form of charity

Now, for my biggest donation yet . . .

I gazed in awe at the new stadium, the future home of Spurs, wondering where my treasures will go. It is going to be one of the architectural wonders of the modern world (football stadia division), yet at the same time it seems ancient, archaic, a Roman ruin, very much like an amphitheatre I once saw in Croatia. It’s at the stage in a new construction when you can see all the bones and none of the flesh, with huge tiers soaring up into the sky. You can’t tell if it’s going or coming, a past perfect ruin or a perfect future model.

It has been so annoying at White Hart Lane this past year or so, having to walk round walkways and under awnings and dodge fences and hoardings, losing all sense of direction. Millions of pounds were being poured into what appeared to be a hole in the ground. The new stadium will replace part of one end of the present one, which was built in 1898. It has been hard not to be unaware of what’s going on, continually asking ourselves, as we take our seats: did the earth move for you?

Now, at long last, you can see what will be there, when it emerges from the scaffolding in another year. Awesome, of course. And, har, har, it will hold more people than Arsenal’s new home by 1,000 (61,000, as opposed to the puny Emirates, with only 60,000). At each home game, I am thinking about the future, wondering how my treasures will fare: will they be happy there?

No, I don’t mean Harry Kane, Danny Rose and Kyle Walker – local as well as national treasures. Not many Prem teams these days can boast quite as many English persons in their ranks. I mean my treasures, stuff wot I have been collecting these past 50 years.

About ten years ago, I went to a shareholders’ meeting at White Hart Lane when the embryonic plans for the new stadium were being announced. I stood up when questions were called for and asked the chairman, Daniel Levy, about having a museum in the new stadium. I told him that Man United had made £1m the previous year from their museum. Surely Spurs should make room for one in the brave new mega-stadium – to show off our long and proud history, delight the fans and all those interested in football history and make a few bob.

He mumbled something – fluent enough, as he did go to Cambridge – but gave nothing away, like the PM caught at Prime Minister’s Questions with an unexpected question.

But now it is going to happen. The people who are designing the museum are coming from Manchester to look at my treasures. They asked for a list but I said, “No chance.” I must have 2,000 items of Spurs memorabilia. I could be dead by the time I finish listing them. They’ll have to see them, in the flesh, and then they’ll be free to take away whatever they might consider worth having in the new museum.

I’m awfully kind that way, partly because I have always looked on supporting Spurs as a form of charity. You don’t expect any reward. Nor could you expect a great deal of pleasure, these past few decades, and certainly not the other day at Liverpool when they were shite. But you do want to help them, poor things.

I have been downsizing since my wife died, and since we sold our Loweswater house, and I’m now clearing out some of my treasures. I’ve donated a very rare Wordsworth book to Dove Cottage, five letters from Beatrix Potter to the Armitt Library in Ambleside, and handwritten Beatles lyrics to the British Library. If Beckham and I don’t get a knighthood in the next honours list, I will be spitting.

My Spurs stuff includes programmes going back to 1910, plus recent stuff like the Opus book, that monster publication, about the size of a black cab. Limited editions cost £8,000 a copy in 2007. I got mine free, as I did the introduction and loaned them photographs. I will be glad to get rid of it. It’s blocking the light in my room.

Perhaps, depending on what they want, and they might take nothing, I will ask for a small pourboire in return. Two free tickets in the new stadium. For life. Or longer . . .
