Scientific Proof That High Frequency Trading Induces Adverse Changes In Market Microstructure And Dynamics, And Puts Market Fairness Under Question

Scientific Proof That High Frequency Trading Induces Adverse Changes In Market Microstructure And Dynamics, And Puts Market Fairness Under Question

Up until recently, any debate between proponents and opponents of High Frequency Trading would typically be represented by heated debates of high conviction on either side, with discussions rapidly deteriorating into ad hominem attacks and the producer screaming ‘cut to commercial’ to prevent fistfights. Luckily, all this is about to change. In a research paper by Reginald Smith of the Bouchet Franklin Institute in Rochester titled "Is high-frequency trading inducing changes in market microstructure and dynamics?" the author finds that he "can clearly demonstrate that HFT is having an increasingly large impact on the microstructure of equity trading dynamics. Traded value, and by extension trading volume, fluctuations are starting to show self-similarity at increasingly shorter timescales. Values which were once only present on the orders of several hours or days are now commonplace in the timescale of  seconds or minutes. It is important that the trading algorithms of HFT traders, as well as those who seek to understand, improve, or regulate HFT realize that the overall structure of trading is influenced in a measurable manner by HFT and that Gaussian noise  models of short term trading volume fluctuations likely are increasingly inapplicable."

In other words, the author finds ample evidence that during the past decade (on the NASDAQ) and especially since the 2005 revision of Reg NMS (on the NYSE), stock trading increasingly demonstrates "self similar" fractal patterns, resulting in volatility surges, recursive feedback loops, and a market structure which is increasingly becoming a product of the actual trading mechanism. In the process, as demonstrated by a Hurst Exponent gravitating increasingly further away from 0.5 (i.e., Brown Noise territory), the Markov Process nature of stock trading is put under question, and thus the whole premise of an efficient market has to be reevaluated. Simply said: HFT has been shown to affect the fairness of trading.

The paper is, needless to say, a must read for everyone who has an even passing interest in stock trading and market regulation (alas, yes, that would mean the SEC, and Congress). And while one of the key qualities of the paper is presenting the history and implications of High Frequency Trading, and its rise to market dominance primarily as a result of the revision…

Depression Coming or Is the Bottom Already In? Joe Friday Says Your Answer Lies Here!

Courtesy of Chris Kimble

Are we headed towards a Depression or is the worst already behind us? In today’s world, comparisons to the great depression are easy to find.

Are the Depression concerns well founded or are the declines of late already pricing in a bottom?

In my humble opinion, this chart and the upcoming price action of this index will go miles and miles towards telling us if we are headed towards very tough times or if the huge declines of late are actually in a bottoming process.

This chart looks at the Thomson Reuters Equal Weighted Commodity Index on a monthly basis over the past 54 years. The index has been heading south, reflecting weakness in demand for basi...

Anyone holding bitcoin would have watched the market with alarm in recent weeks. The virtual currency, whose price other cryptocurrencies like ethereum and litecoin largely follow, plummeted from more than US$10,000 (£8,206) in mid-February to briefly below US$4,000 on March 13. Despite recovering to the mid-US$6,000s at the time of writin...
