High Frequency Trading

Proponents of high frequency trading tell us that they’re doing us all a service by improving liquidity in markets, which supposedly benefits everyone. However, to implement their strategy they’re prepared to pay a fee to get microscopically early access to prices. So, if you take the liquidity argument seriously, this suggests that these altruistic traders are paying stockmarket operators to give the rest of us a free ride, out of the kindness of their hearts.

Presumably no one really believes this. However, the trouble is that the rise of the machines exposes the fragile markets of the world to yet another possible source of mass extinction. Time for the Terminator. Again.

Automated and Algorithmic

The concept behind high frequency trading is simple. Practitioners pay a fee to markets to get access to real-time data a tiny fraction ahead of everyone else and then hugely powerful computer systems driven by automated trading software search out short term pricing anomalies and seek to exploit them.

Hidden deep behind this is the idea that although stock prices theoretically follow a random walk – which essentially means that a stock’s price in future is not predictable from its price now (which would thus instantly invalidate a thousand trading strategies) – there is evidence of autocorrelation in markets which says that this isn’t quite true. As Campbell, Lo and MacKinley put it in The Econometrics of Financial Markets:

"The fine structure of securities markets and frictions in the trading process can generate predictability. Time-varying expected returns due to changing business conditions can generate predictability. A certain degree of predictability may be necessary to reward investors for bearing certain dynamic risks."

It may be a wild shot in the dark but I’m guessing the authors think that there may be some predictability in market behaviour. The evidence they quote supports them.

Short-term trading techniques aim to exploit this asymmetry in markets. However, the ultra-fast reaction times of the latest market networks and the power of the supercomputers employed has changed the rules. These systems give the high frequency traders a tiny and fleeting advantage over other market participants. Tiny and fleeting, however, can be enough to make lots and lots of money if you do it often enough.

What Happens Next In The Global Trade War: A Q&A With Goldman Sachs

Courtesy of Zero Hedge

Today, according to Politico, the White House will unveil its plan to hit China with tariffs and other trade restrictions, one day ahead of schedule as President Trump is slated to outline the results of U.S. Trade Representative Robert Lighthizer's investigation into allegations that China violates U.S. intellectual property rights by forcing American companies to transfer valuable technology to Beijing.

Lighthizer’s office has determined that the US loses at least $30BN a year to China’s alleged forced technology transfers, and the administration is weighing a package of tariffs equivalent to that amount of Chinese imports; according to Reuters it could be as high ...

If you haven’t already heard of Bitcoin, you either haven’t been paying attention or you’re a time traveller who just touched down in 2018. Because by now, most of us will have heard of Bitcoin and some of us have even jumped on the bandwagon, investing in cryptocurrencies.

But despite its popularity, many people still don’t understand the technology that underlines it: blockchain. In...

Bears Take Control

Courtesy of Declan.

More decisive action from bears today as markets lose support.  The S&P undercut the rising trendline and 20-day plus 50-day MAs in a move which looks like it could develop into a test of the February spike low and the 200-day MA again; support at 2,695 is looking critical here. Aggressive traders could look to buy at these levels but confidence in this holding would not be high.

The Dow also saw its 'bear flag' / consolidation triangle resolve to the downside. The two positives were the relatively light volume and the ...

The tricks propagandists use to beat science

Via Jean-Luc

How propagandist beat science – they did it for the tobacco industry and now it's in favor of the energy companies:

The tricks propagandists use to beat science

The original tobacco strategy involved several lines of attack. One of these was to fund research that supported the industry and then publish only the results that fit the required narrative. “For instance, in 1954 the TIRC distributed a pamphlet entitled ‘A Scientific Perspective on the Cigarette Controversy’ to nearly 200,000 doctors, journalists, and policy-makers, in which they emphasized favorable research and questioned results supporting the contrary view,” say Weatherall and co, who call this approach biased production.

A second approach promoted independent research that happened to support ...
