HFT: Makings of an Evil Empire

Wall Street's reputation may be damaged, but don't blame all of the industry's woes on high-frequency trading.

Perhaps we can blame the public's negative view of high finance all on Wall Street, the movie. Wall Street is an easy target, especially after the financial crisis of 2008. For most people, it equates to greed and overconsumption and nothing more. In extreme cases, anyone who works on Wall Street is viewed as someone who sucks the life out of honest working folks on Main Street.

HFT EvolutionWall Street & Technology's April 2013 digital issue takes an in-depth look at how high-frequency technology firms are using microwave and other technologies to survive in a challenging market. To read more, download our April 2013 digital issue now.

I haven't seen any polls on this, but I imagine that Wall Street's popularity is on par with, if not slightly worse than, views on Congress. That's how bad things are for Wall Street. Now it turns out that there are worse things in high finance than Wall Street itself: We have identified a purely evil force known as high-frequency trading.

In Star Wars, it was pretty easy to identify evil in Darth Vader. Gordon Gekko in Wall Street certainly looked the part of the unscrupulous global financier. Unfortunately, when it comes to HFT, it's difficult to nail down exactly what is evil. I've met with many so-called "high-frequency traders," and trust me, most don't look anything like anyone on Wall Street. In fact, one of them reminded me of my middle school math tutor.

High-frequency trading isn't done by a homogeneous group of firms that engage in specific trading activities with a particular agenda. Lack of a coherent identity among these firms makes it easier for opponents to label them as bad for the market and harder for those engaged in high-frequency trading to respond in a coordinated way.

There have been many academic studies on high-frequency trading in the last few years. Some of them show that HFT is good for the market, while others say it's harming investors. I'm not smart enough to figure out exactly which camp wins this data-driven discourse, but I've been around this industry long enough to realize that it's possible to use the same data set to support polar-opposite views.

For HFT opponents, firms in this category are evil, they're making gobs of money unfairly and they'll ultimately destroy the foundation of the capital markets. The leaders at these firms are way smarter than everyone else and have spent mind-numbing amounts of money on technology to create an unfair advantage over the rest of the marketplace. The only way we can stop them is to come up with onerous regulations to curtail their high-frequency ways.

Process Of Elimination

I'm not going waste my time trying to come up with different definitions of HFT other than to state that in my opinion, HFT isn't a type of firm but a mode of trading. What I would like to do, however, is to point out a few things that I've seen in the last four years that clearly have nothing to do with HFT. This approach is like the process-of-elimination methodology that students use to take the SATs. They might not know the answer, but at least they can get rid of the obviously wrong ones and then have a better chance of picking the correct one. So here's a list of items that aren't related to high-frequency trading:

— HFT didn't cause the global financial crisis in 2008.

— It doesn't hate regulations; in fact, one can reasonably argue that only within a proven and stable regulatory framework (Reg NMS) could HFT even exist.

— HFT isn't flash orders or dark pools.

— It wasn't the main cause of the flash crash; that can be blamed on market fragmentation and electronic trading in general (which would include HFT).

— Bear Stearns, J.P. Morgan, Lehman Brothers, Bernard Madoff, Stanford Financial Group, MF Global, Knight Capital, Societe Generale and the like aren't HFT firms (though most of the banks mentioned here have or have had HFT units within their trading operations).

— HFT didn't cause global warming.

re: HFT: Makings of an Evil Empire
I don't think that Getco's acquisition of Knight spells the end of HFT at all. It suggests they will use this order flow to generate higher transaction volumes and commissions from retail brokers. It could also help them make better prices in their market making.The actual trading will still occur in an algorithmic/HFT-manner. I don't see where HFT is phasing out as a style of trading, though it has become less profitable in US equities. I think your neighborhood analogy is very good. In response to HFT moving into the equity neighborhood, institutions have had to adopt similar techniques.

re: HFT: Makings of an Evil Empire
Aside from the problems or lack of thereof caused by HFT, it seems it would be more equitable (perhaps even work to reduce flash crashes) if the markets moved to a periodic or batch from of trading rather than 'instantaneous' trading.

Let all participants see the starting order book (ask/bids). Each participant then sends in the buy / sell orders. These orders are resolved as batch, say every 5 minutes (or at some other suitable period). The participants cannot see the new orders until at the end of the current period.

In some cases, where there are multiple bids, a random process may be used to settle the trades in a fair way.

re: HFT: Makings of an Evil Empire
Yes, we are definitely seeing several HFT firms diversifying as their profits start to dwindle. The low latency race seems to have slowed too. With regulators expected to increasingly focus on HFT, could this spell the end of HFT as we know it, or at least a significant shift?
