Who does early access to sensitive data really hurt?

Masters of the Universe, or dummies?

The Wall Street Journal reports on the perils of providing early access to sensitive economic data:

The early look at the consumer-sentiment findings comes from Thomson Reuters Corp. The company will pay the University of Michigan $1.1 million this year for rights to distribute the findings, according to the university. Next year, it will pay $1.2 million.

In turn, Thomson Reuters's marketing materials say the firm offers paying clients an "exclusive 2-second advanced feed of results…designed specifically for algorithmic trading."

Clients who pay a subscription fee to Thomson Reuters, which for some is $5,000 a month plus a $1,025 monthly connection charge, get the high-speed feed at 9:54:58 a.m. Eastern time.

Those who pay for Thomson Reuters's regular news services get the report two seconds later. At that point, it swiftly becomes widely available through other news providers as well.

Take a look at what happens to the trading volume in those two seconds:

That obviously makes sense. If you pay thousands of dollars for an advance connection, you're presumably doing to want to act on it. That two-second preview gives anyone who can afford it and some algorithms smart enough to parse the information a huge advantage in the market.

Except that every trade needs a counterparty. That is, if bad data comes out and you decide to sell some shares, someone else needs to buy them. If you know that some people in the market have access to secret data which you will get in less than two seconds, the reasonable thing to do is not trade for the next two seconds. Who are these idiots who make willing counterparties to traders with inside information?

One possibility is that people are leaving buy or sell orders open over the period of the release. So, for instance, if you decide on Monday that you want to buy a share of Acme Corp. for $100 when it's trading at $105, you may end up being stuck with it if the value plunges to $90 in two seconds on Tuesday. Of course, that's still a certain amount of stupidity, but it makes it easier to understand criticism that early access to such data hurts so-called "mom and pop" traders.

But there's another possible explanation, which is that all these trades are between people with early access to the data. We might both think the information is bad, but if you think its worse than I do, I may well be prepared to buy from you – albeit at a price lower than I would have before I found out the news. And if the release is borderline, it's even more likely that the counterparties also have information. Everyone thinks they're smarter than the crowd, otherwise they wouldn't bother trading.

If that's the case, then there are still dummies in the mix; but they're the ones paying thousands of dollars a month for the chance to take a stab in the dark two seconds before the general public.

The decline of the north's sporting powerhouse

Yorkshire historically acted as a counterweight to the dominance of southern elites, in sport as in politics and culture. Now, things are different.

On a drive between Sheffield and Barnsley, I spotted a striking painting of the Kes poster. Billy Casper’s two-fingered salute covered the wall of a once-popular pub that is now boarded up.

It is almost 50 years since the late Barry Hines wrote A Kestrel for a Knave, the novel that inspired Ken Loach’s 1969 film, and it seems that the defiant, us-against-the-world, stick-it-to-the-man Yorkshireness he commemorated still resonates here. Almost two-thirds of the people of south Yorkshire voted to leave the EU, flicking two fingers up at what they saw as a London-based establishment, detached from life beyond the capital.

But whatever happened to Billy the unlikely lad, and the myriad other northern characters who were once the stars of stage and screen? Like the pitheads that dominated Casper’s tightly knit neighbourhood, they have disappeared from the landscape. The rot set in during the 1980s, when industries were destroyed and communities collapsed, a point eloquently made in Melvyn Bragg’s excellent radio series The Matter of the North.

Yorkshire historically acted as a counterweight to the dominance of southern elites, in sport as in politics and culture. Yet today, we rarely get to hear the voices of Barnsley, Sheffield, Doncaster and Rotherham. And the Yorkshire sporting powerhouse is no more – at least, not as we once knew it.

This should be a matter of national concern. The White Rose county is, after all, the home of the world’s oldest registered football club – Sheffield FC, formed in 1857 – and the first English team to win three successive League titles, Huddersfield Town, in the mid-1920s. Hull City are now Yorkshire’s lone representative in the Premier League.

Howard Wilkinson, the manager of Leeds United when they were crowned champions in 1992, the season before the Premier League was founded, lamented the passing of a less money-obsessed era. “My dad worked at Orgreave,” he said, “the scene of Mrs Thatcher’s greatest hour, bless her. You paid for putting an axe through what is a very strong culture of community and joint responsibility.”

The best-known scene in Loach’s film shows a football match in which Mr Sugden, the PE teacher, played by Brian Glover, comically assumes the role of Bobby Charlton. It was played out on the muddy school fields of Barnsley’s run-down Athersley estate. On a visit to his alma mater a few years ago, David Bradley, who played the scrawny 15-year-old Billy, showed me the goalposts that he had swung from as a reluctant goalkeeper. “You can still see the dint in the crossbar,” he said. When I spoke to him recently, Bradley enthused about his lifelong support for Barnsley FC. “But I’ve not been to the ground over the last season and a half,” he said. “I can’t afford it.”

Bradley is not alone. Many long-standing fans have been priced out. Barnsley is only a Championship side, but for their home encounter with Newcastle last October, their fans had to pay £30 for a ticket.

The English game is rooted in the northern, working-class communities that have borne the brunt of austerity over the past six years. The top leagues – like the EU – are perceived to be out of touch and skewed in favour of the moneyed elites.

Bradley, an ardent Remainer, despaired after the Brexit vote. “They did not know what they were doing. But I can understand why. There’s still a lot of neglect, a lot of deprivation in parts of Barnsley. They feel left behind because they have been left behind.”

It is true that there has been a feel-good factor in Yorkshire following the Rio Olympics; if the county were a country, it would have finished 17th in the international medals table. Yet while millions have been invested in “podium-level athletes”, in the team games that are most relevant to the lives of most Yorkshire folk – football, cricket and rugby league – there is a clear division between sport’s elites and its grass roots. While lucrative TV deals have enriched ruling bodies and top clubs, there has been a large decrease in the number of adults playing any sport in the four years since London staged the Games.

According to figures from Sport England, there are now 67,000 fewer people in Yorkshire involved in sport than there were in 2012. In Doncaster, to take a typical post-industrial White Rose town, there has been a 13 per cent drop in participation – compared with a 0.4 per cent decline nationally.

Attendances at rugby league, the region’s “national sport”, are falling. But cricket, in theory, is thriving, with Yorkshire winning the County Championship in 2014 and 2015. Yet Joe Root, the batsman and poster boy for this renaissance, plays far more games for his country than for his county and was rested from Yorkshire’s 2016 title decider against Middlesex.

“Root’s almost not a Yorkshire player nowadays,” said Stuart Rayner, whose book The War of the White Roses chronicles the club’s fortunes between 1968 and 1986. As a fan back then, I frequently watched Geoffrey Boycott and other local stars at Headingley. My favourite was the England bowler Chris Old, a gritty, defiant, unsung anti-hero in the Billy Casper mould.

When Old made his debut, 13 of the 17-strong Yorkshire squad were registered as working-class professionals. Half a century later, three of the five Yorkshiremen selec­ted for the last Ashes series – Root, Jonny Bairstow and Gary Ballance – were privately educated. “The game of cricket now is played in public schools,” Old told me. “Top players are getting huge amounts of money, but the grass-roots game doesn’t seem to have benefited in any way.”

“In ten years’ time you won’t get a Joe Root,” Rayner said. “If you haven’t seen these top Yorkshire cricketers playing in your backyard and you haven’t got Sky, it will be difficult to get the whole cricket bug. So where is the next generation of Roots going to come from?” Or the next generation of Jessica Ennis-Hills? Three years ago, the Sheffield stadium where she trained and first discovered athletics was closed after cuts to local services.
