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…

Ethical challenges loom over decisions to resume in-person college classes

I don't see how universities can be safely reopened. Classes may have to shift to largely or only online. Dorms, if they reopen, would probably need to limit rooms to one person, and maybe only for students without other options. This would obviously be a financial disaster for many colleges and millions of people. The federal government would ideally step in to help universities and employees survive financially. Any thoughts?

Golds quick price move increases the odds of a correction

Courtesy of Read the Ticker

Every market corrects, maybe profit taking, maybe of allowing those who missed out, to get in!


The current open interest on the gold contract looks to high after a very fast price move, it looks like 2008 may be repeating. A quick flushing out of the weak hands open interest may take place before a real advance in price takes place. The correction may be on the back of a wider sell off of risk assets (either before of after US elections) as all assets suffer contagion selling (just like 2008).

This blog view is a gold price correction of 10% to 20% range is a buying opportunity. Of course we may see  a very minor price correction but a long time correction, a price or time is correction is expected, we shall watch and...

We’ve continued to attempt to warn investors of the risks ahead for the US and global markets by generating these research posts and by providing very clear data supporting our conclusions.  Throughout the entire months of May and June, we’ve seen various economic data points report very mixed results – and in some cases, surprise numbers as a result of the deep economic collapse related to the COVID-19 virus event.  This research post should help to clear things up going forward for most traders/investors.

As technical traders, we attempt to digest these economic data factors into technical and price analysis while determining where and what ...

The tech bubble didn’t end well. BUT it did tell us that the world was shifting into the technology age…

Since the Nasdaq 100 bottomed in 2002, the broader markets have turned over leadership to the technology sector.

This can be seen in today’s chart, highlighting the ratio of Nasdaq 100 to S&P 500 performance (on a “monthly” basis).

As you can see, the bars are in a rising bullish channel and have turned sharply higher since the 2018 stock market lows. This highlights the strength of the Nasdaq 100 and large-cap tech stocks.

These Charts Show COVID 19 Is Spreading in the US and Will Kill the Economy

The COVID 19 pandemic is, predictably, worsening again in much of the US. Only the Northeast, and to a lesser extent some Midwestern states, have been consistently improving. And that trend could also reverse as those states fully reopen.

The problem in the US seems to be widespread public resistance to recommended practices of social distancing and mask wearing. In countries where these practices have been practi...
