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.

If Caribbean governments can’t afford to rebuild their islands, maybe big tech firms can?

November 20 marked the end of the Atlantic hurricane season, but for the Caribbean, it’s only the beginning of a painful recovery process.

In early September, Hurricane Irma largely destroyed Barbuda and several neighboring Lesser Antilles islands. Two weeks later, Maria took a final fatal...

Russell 2000 and Semiconductor New Highs / S&P Breaks

The S&P broke higher to confirm a 'bear trap' and also closed at a new all-time high. Volume climbed to register an accumulation day but there were further losses in relative performance and continued losses in the MACD.


The Nasdaq posted a gap-driven 1% gain to bring it ever closer to channel resistance. It hasn't yet tagged resistance but it looks well placed to do so by the end of the week. Technical are all bullish.
