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.

Coronavirus: the blow to the Chinese economy could be felt for years

Investors are still being fairly complacent about the novel coronavirus. After the number of new daily cases suddenly shot up to more than 15,000 on February 12 following more than a week of decline, there were some jitters in the markets. With Chinese authorities saying the increase was due to a decision to broaden the definition for diagnosing people, there were falls in the region of 1% in European markets, and smaller retrenchments in Asia and North America.

Is The Technology Sector Setting Up For A Crash? Part I

Courtesy of Technical Traders

One thing that continues to amaze our research team is the total scale and scope of the Capital Shift which is taking place across the globe.  For almost 5+ years, foreign investors have been piling into the US stock market chasing the stronger US dollar and continued advancement of US share prices. It is almost like there is no other place on the planet that will allow investors to pool capital into such a variety of strong assets while protecting against foreign capital risks.  Yet the one big question remains – when will a price reversion event hit the US stock
market?

So many researchers, even our team of researchers, believe we have found the keys to unloc...
