Good morning, everybody. This is Preston Pysh, I’m your host for The Investor’s Podcast. And I’m accompanied by my co-host, Stig Brodersen. And today, we are going to be talking about something that I think very few people would have ever guessed that Stig Brodersen and Preston Pysh would ever be talking about, and that is high frequency trading. This is really interesting. I’m just going to shoot that out there, folks. 

So if you’ve never read or listened to anything on high frequency trading, I think there are some things today that we’ll be talking about that’s going to be blowing your mind. And so the premise of our discussion today is Michael Lewis’ new book that came out. I don’t know how new it is. What is it? Maybe half a year old? Something like that? Yeah.

Stig Brodersen  0:55  

From March or something?

Preston Pysh  0:56  

Yeah. So okay, 14, there you go. March 2014. So not too new, but it’s something that has come out in the past year. So in Michael Lewis’ book, and for anyone that’s not familiar with Michael Lewis, this guy’s probably one of the best writers that covers Wall Street that’s out there. You’ll probably recognize him more from his movie, The Blind Side, which was done with Sandra Bullock. It was a movie about football. He was the writer for the movie Moneyball, which was with Brad Pitt. He wrote a book back in 2008, after the stock market crash called The Big Short. And now he’s got this book called, Flash Boys. 

And I’ll tell you, I am a huge fan of Michael Lewis’ work. I mean, his writing is just spectacular. So that’s what the book that we’re covering today is dealing with the rise of high frequency trading. We’ve got 2 segments for the show today. We’re going to first talk about the kind of the general outline of the book and what’s discussed in the book. 

And then at the very end, Stig and I are going to give our thoughts on high frequency trading. So those are really the two segments. So the book starts off with a company called Spread Networks, and what they’re doing is they’re running a fiber optic cable line from Chicago to New York. 

Now that might not sound like it’s all that interesting. But as you discover in the book, the Spread Networks is building this line. And what they’re doing is they’re trying to build the line as straight as possible between Chicago and New York. And it talks about their ridiculous efforts in order to keep this line as straight as possible. 

They’re like digging underneath roads and trying to run it through mountains and get it to New York as straight as possible. And you’re just wondering, why in the world would a company be spending that much money, first of all, to build this? And what in the world do they need it for? And so the length of this line is 827 miles between Chicago and where it ends in New Jersey, which is right there by the New York Stock Exchange. 

And the purpose of the line is so that trades can be conducted for milliseconds faster than the current fiber optic cables that existed before Spread Networks came in and did this. And so that’s kind of how he starts this book. And I know when I was reading it, I was like, what in the world is this? Stig, what were your thoughts? I don’t know if you were familiar with this before reading the book. But I was blown away when I was reading this.

Stig Brodersen  4:23  

I was blown away as well. And one thing that really puzzled me was they kept talking about nanoseconds, milliseconds. And to be quite honest, I wasn’t sure about how long that was. So I think he gives that one example that the blink of an eye is something around 300-400 milliseconds which is from .3 to .4 of a second. And what Preston just said is that the whole reason that they built this long cable running through mountains and rivers, that is just to say, 4 milliseconds.

Preston Pysh  4:56  

So that’s just crazy. Just crazy. They saved four milliseconds, and they spend millions upon millions of dollars in order to do this. So that’s kind of the introduction to high frequency trading and what it’s all about. It is all about the speed. So let’s go ahead and start talking more about this book. So whenever we start digging into the book, it really kind of comes down to the story of two different gentlemen. The first guy, his name is Brad Katsuyama, and he used to work for a Canadian bank. And then the other person, his name is Sergey Aleynikov and he worked at Goldman Sachs as a programmer for a lot of this high frequency trading. And so it kind of tracks and it’s, I don’t want to say it’s real linear. The book kind of jumps around a little bit, talking about their different stories and it kind of…

I like the way that it’s structured because it makes it really interesting. You’re kind of wondering what’s happening next. It almost kind of reads like a movie and you can kind of see where Michael Lewis got a hold on his writing skills from.

To give you guys some quick stats on high frequency trading, so in the United States and this stat came from 2009, high frequency trading firms represented 2% of the approximate 20,000 firms operating today. But it accounted for 73% of all equity or stock order volume. So, although these companies are like, there’s just a couple of them out there, a few of them, they’re accounting for 73% of the trades on the stock market which I think is just mind blowing. 

And what the book talks about, as you go further through it, it starts talking about some of these strategies and how these companies are doing this. And I’ll be honest with you, after reading the book, and spending all that time kind of trying to understand this, it is still confusing and is still difficult to understand. And I think that’s one of the main reasons why there’s only a few people or a few companies out there that are doing this. And they’re able to really kind of make, in my opinion, a mockery of a lot of these big businesses like Goldman Sachs, Bank of New York Mellon, and you name it, all these banks are conducting all these trades. 

All these high frequency owners are crushing them and pretty much telling them what they will and will not do when it comes to trading stocks. So let’s go ahead and quickly discuss some of the different strategies that high frequency traders implement. So from the research that I did, and this doesn’t really come from the book, he doesn’t really go into each of the strategies. But we’re going to do that here on this episode. So the first one is a market making strategy. 

The next one that we have is a ticker tape trading strategy. They got event arbitrage. They got statistical arbitrage. They have news based trading. And they have low latency strategies that they implement. So you can see, it’s not like they’re just doing one type of trading here. But the one that we’re going to talk about and kind of give you an example of is this last one with the low latency trading, or I’m sorry, the low latency strategies. 

And this is one that Michael Lewis covered in the book. And it revolves around this idea of basically using arbitrage in order to conduct trades faster than the other person. So what in the world does that mean? So I’m going to give you an example. So let’s say that instead of trading stock in a market, let’s say that we’re buying and selling apples in a market. Literally, like apples that you would eat. Because it’s not really that much different when you talk about, you know, market strategies. 

Let’s say that I was going to go and buy 1000 apples from a fruit market. Okay. And in order to do that, that’s a pretty large order of apples. I mean, if I go to market they might not have 1000 apples for me to buy. They might only have 100, when I arrived at the first market. Let’s see that there’s, you know, five different fruit markets all around the area where I live. And I go up to the very first market and I want to buy 100 apple or I want to buy 1000 apples. But whenever I get there, I see that the the vendor only has 100 apples to sell me. So when I go up there and I tell them, hey, I’d like to buy 1000 apples. He says, I’m sorry, I can only sell you 100 at $1 per apple. So I obviously conduct that trade and I would buy those hundred apples for $100. 

But this is where things get a little tricky. And this is where we’re describing how high frequency trading works or at least one of the strategies that they use with high frequency trading. So let’s say that Stig was standing right there, and he watched this order and this transaction take place, this event. And Stig saw that I was trying to buy 1000 apples. And he also saw that I only purchased 100 apples and he saw the price that I paid for them. So what Stig does, and let’s say that I’m just driving in my car from market to market. 

Well Stig, he owns a helicopter and he listened to this order take place, okay. He goes and he gets in his helicopter and he flies to the next market because he knows I’ve got another 900 apples to buy. And me, I get in my car and I’m driving to the next market. So do you see the advantage that’s happening here? Stig is able to take that piece of information that he knows at the event, okay. He knows as much as I know at this point, but he has an advantage. He has a speed advantage in order to get to the other market faster than me. 

And so, he goes to the next market, and at the next market which we’ll call, market B, Stig finds that there’s another vendor. They’re selling yet another hundred apples. And so he buys that hundred apples for $1 per apple. He spends $100 buying these apples. And then he sells the apples back to the original vendor. Okay, immediately sells them right back to the person who he just bought them from, and he sells them to the guy for $101. And sure enough, he knows that I’m on my way, I’m driving to that market in order to purchase those apples. 

So in some cases, Stig could sell those apples back to me directly, or he could just sell them back to the person he just bought them from at a higher price, telling that person that there’s a person coming to buy 1000 apples. Here’s your $100, so you can charge them $101 or whatever the case might be. But whether he’s selling them to me or he’s selling them back to the original person doesn’t really much matter. 

What does matter is that Stig beat me to that order, okay. He jumped out in front of me and he was able to purchase it faster than I was able to purchase it. And so this takes place at all the different markets across the US, around the world. And these high frequency traders are faster and they’re able to execute the orders quicker than the other person can arrive. So Stig, go ahead. I saw you had something you wanted to add.
