Announcer: You're listening to Tradestreaming Radio with your Host, Zack Miller.  Expand your mind, become a better investor with tools, tips and technology from the smartest investors on the planet.Zack: Welcome to Tradestreaming Radio. I'm your host Zack Miller, and this is the place where smart investors come to learn directly from experts. We help bubble up tools, tips and technologies to help you make better, smarter investment decisions. And today's guest on the program helps me to do that. Today we have Wes Gray on the show. He is a Professor of Finance at Drexel University, he's also behind a new website called TurnkeyAnalyst.com. He also has a private investment firm that invests directly in some of the strategies that he investigates. I like Wes because he sacrifices sacred cows, he looks at, at research with a very, very objective focus and he's not afraid to actually look for actionable, tradable strategies, as opposed to just focusing on Ivory tower type stuff.

I'm currently an Assistant Professor of Finance at Drexel University and also run two [inaudible 01:44], one is TurnkeyAnalyst.com and then another one is [PureCharge], which is a investment managed business. Zack: So, is it hard to keep those two things separate? Wes: Not really. The job at Drexel is primarily do research on financial markets. Actually, we get a lot of complementary, what I do for TurnKey I also do for our investment which is research on financial markets, so a lot of times, they fuel each other. We may be trading on here or researching something that we want to implement and then, as we get into it, we're like, "Wow. This is really interesting. This hasn't been discussed in academic literature, so we should write a paper about it." Or I'll be doing some focused trade on academics, I'm like, "Wow. This is really interesting, and we do a few twists and turns and it can be something that's very useful for training on or writing about, or what have you. So I think there's kind of a nice synergy between the two. Zack: It's almost like you have your own built in laboratory to test out some trading theories? Wes: I'm sorry. Say it again. Zack: So it's almost like you have your own personal laboratory to test some of this stuff? Wes: Yeah, pretty much. We work with a couple family options and we've got a lot of people work for us, helping doing research and pro-. Yeah, we come up with good ideas. I'm almost look at our entire firm as just an R&B shop, essentially. So, we got an idea, we'll test it or if we got ideas we tested and we can either test on our real monies, see if it actually works. If it does, then yeah, [inaudible 03:28] write something up and maybe try to get some publicity from it by publishing an article or just sharing our knowledge. Zack: What I like about, I don't know too much about Investment Shop obviously, but from what you're doing publicly on TurnKey Analyst, I like your approach where you, it's like a no non-sense, no BS type approach where you're not necessarily comfortable with just accepting status quo. I remember one piece in particular that you did that stands out in my mind, is when you looked at the Magic Formula and so, in some way Joel Greenblatt's been given a free pass from our entire industry and you weren't able to replicate his results, were you? Wes: No, I wasn't and big picture at TurnKey Analyst is what I call our, my for passion business, not the for profit. And the more I [hear] there in the mission statement is what I call democratized quant. Because I just think people, if they understood a little bit about quantitative financing, that they'd make better portfolio decisions and understanding a little bit more what they're actually investing in and one of the things that we know that everyone really enjoys, and I think they should, is Greenblatt's Book where he outlines this really [inaudible 04:45] concept of, look at quality, look at price, take the best combination and go buy those stocks. And I actually really like Joel Greenblatt's work and everything and I don't think he meant to do it, but in his book he has these crazy returns where it says it's like 31 percent CAGR from, I don't know, what was it? 88? Zack: Twenty years, or something. Wes: It's kind of insane, so it was like, "All right." Go back, [inaudible 05:14] thousands of [inaudible 05:17] every [inaudible 05:18] under the sun. And we just couldn't imagine a, but the reality is I don't think that he would disagree with our results, because we're at the [inaudible 05:29] Congress last, was it last October in New York, and he gave one of the presentations. He showed his returns, the [inaudible 05:39] portfolio returns, because he had an updated data thing. It really wasn't exactly like the returns that we posted on TurnKey Analyst. And it was no mention of the 31 percent CAGR anymore. So I don't know if they maybe redone those results when they came out of like, well actually, we made a mistake. Perhaps you would never want to publicly admit, you just kind of let it slide under. But, well, that's just, that's how it rolls. Everyone makes mistakes and, or maybe it's just a lucky fluke. The [inaudible 06:09] when they did those portfolios in the top 30 stocks and you equal weight them, which gives you some diversification, but there could be, maybe one stock you happen to get, I don't know, Apple in there at the exact right time, that just in itself could potentially drive results. I don't know if they could drive it like that but, who knows. Bottom line is that [inaudible 06:36] Zack: It still performed pretty well though, right? Wes: Yeah. I know, exactly. But that's the main thing. I think people may have misinterpreted, where does [Ashley Greenbaum], because I think Greenbaum does a huge service for society and investors to give them access to do the Magic Formula, not worry about picking stocks and paying maybe even higher fees than they would in other venues. And I think the system would work and just as he mentions in his book, in his book, it's common sense, it's [inaudible 07:08], it's not going to give you a nice Madoff return. [inaudible 07:14] on the long term, so that's certainly the case, maybe add to town what [inaudible 07:19] planned, anywhere from 200-500 basis points over long, long holding [inaudible 07:26]. Which is great. I just think that people shouldn't expect to get 15 or 20 percent over market over a long time period, because the mathematics of that just would make everyone Warren Buffet really quick. Zack: I thought you had a great piece also out about SumZero. We've had Divya Narendra on the show and I interviewed him for my book. For our guests who don't know, SumZero is like an exclusive expert network comprised of somewhere between 5000-6000 buy-side analysts. It's a closed network, they don't share their stuff outside yet, but you looked at the returns there and I know there's been some work previously on the value investor's club [inaudible 08:10] that performance there. What'd you find with SumZero? Wes: SumZero we, to put it in a nutshell, we, they [inaudible 08:17] their long ideas. We were looking at short term price reactions trying to assess if what these guys write about, does it actually have any market impact in a reliable sense. [inaudible 08:30] on the long side, they do, it's obviously concentrated in smaller stocks where you'd expect that to happen. It would be reasonable to think that somewhere on SumZero's system about GE and all of a sudden the stock moves 10 percent. But if you wanted us to talk about averages, and you want to look across the whole spectrum, it looks like we get a typical bounce over the first three or four weeks of around two to three percent, and it's the [inaudible 08:58] reliable, it's actually there in the data so I don't know if it's what you call [inaudible 09:03], or what do you want to call it, but whatever's happening, these stocks are certainly moving based on the information that Divya, SumZero reports. Zack: And it's a tradable strategy where you could get in theoretically after the pick is made on the site? Wes: Yeah, certainly. There's a drift effect where, I'm just looking at the chart here. Let me pull it up. The papers on [inaudible 09:26] are in, if you want to check it out, but it looks like [inaudible 09:30], or two, you get, these are, again, average statistics and these were also abnormals, controlling for what, just the overall market did. And [inaudible 09:41] till you get a percent or two but then you get a drift so if you go out to 45 days, they have a cumulative abnormal return of over four percent, so let's say you waited a week even, you could still theoretically capture another two percent of, I guess we'll call it Alpha. And I guess the idea would be there is [inaudible 10:02] you had real information, either they had real information or its inside investors should be [inaudible 10:10] information. It's not going to happen immediately, they're going to want to go do their own [inaudible 10:17], slowly build position. So that had to be a reason why it has this lag effect. If you wanted to do it systematically, you could obviously, anytime an idea hits  you'd want to buy in, try to minimize your market impact [inaudible 10:37] trading, and then just ride the wave a little bit. Again, it's concentrated in smaller names are getting, a lot of times you get the big bounces and you know if you're trading small names, it doesn't take too much for you to become the bounce. So it's a self defeating process. Zack: So, it's great, it's sort of like throwing the door open on a lot of things that were considered, taboo is probably too strong of a word, but it's a fresh objective approach. What other things are you working on that are, well even, you don't have to tell us exact pieces but what else are you interested in? Where's your research going to lead you in the future? Wes: One of the [inaudible 11:16] my [self] and my RA who now works with us, and he's PhD student at Drexel, one thing we've noticed, because we've tested, like I said, we've back tested it, you name it, we've back tested it. We've done it long short, done a long only, short only and one of the things that we notice is that a lot of times in academic research or even in practitioner publications, there's this concept of Alpha. An Alpha is really just your right of regression of your returns against some rich factors and they were meant to soak up the rich exposures you're actually taking with that strategy. And waterier remaining kind of excess or that's your Alpha, but one of the things we noticed is people don't really think about draw downs a lot. People in practitioner land do a lot because you actually care about [inaudible 12:06], what we notice is that almost every single long short strategy out there, no matter how good it is, Momentum's a perfect example where you make money for a long, long time and Momentum just do a long short system, but the problem is, and there's a ton of Alpha in the regressions but the draw downs on it puts you into bankruptcy every so often. We think this is a pretty systematic thing where no matter what system, what strategy, it may look like a low risk, unbelievable opportunity, we actually get the monthly returns and you calculate the draw down, almost all of them inevitably have at least an opportunity where you lose 50 percent of your capital. And obviously you're running along short hedge fund and you may bang out your 10, 15 percent a year but [inaudible 12:57] 50 percent draw down you're not going to be in the business anymore. So it's kind of an interesting aspect of long short [inaudible 13:05] typically that a lot of people never think about because they just look at the Alpha as the man or the annual returns or what have you but a lot of times, there's a lot of risk when you capture what's not in a year period but it's in like a three month stretch where, and it could just be [inaudible 13:23]. So we're working on that. Zack: How does some of your work impact individual investors? Obviously, if you're looking, you're democratizing quant, professionals I'm sure really get a lot of value out of some of your research. Is there applications towards the retail investor, the individual investor for some of this stuff? Wes: Yeah. I think one of the most interesting pieces I've ever seen and I actually wrote a little blurb on it, it was done by Greenblatt where he highlights this whole point that, when they did the Magic Formula, they wrote the book and they created this inves-, where you could either do it by yourself or you could do it as the automated system. Zack: Formula Investing? Wes: What's that? Zack: Formula Investing, his firm? Wes: Exactly. The Formula Investing, and the funny thing is when they went back and they backed up to the guys that ran the firm or investing by themselves and the ones that just did it purely with the computer. When people did it by themselves, they actually underperformed the computer and now, [inaudible 14:24] probably is, and that's because we run these things, is [inaudible 14:28] the actual names that drop out of the Magic Formula. A lot of the names are atrocious, like especially right now you see a lot of these for profit educations, you see gain stop, you used to see Blockbuster, all these businesses where they, they had their day in the sun but then you think about, "God, why would we want to own it?" That is literally  what I think drives a lot of the great returns on those systems, but the problem is when, and while I'm getting into this round of [the point 07:26], why we do stuff that's good for retail investors is, retail investors, if they can get beyond the individual gains, if they want to be a quant and use the tools then, we provide those sort of tools and they need to actually be a quant, because the minute you try to be a quant and then you go in and meddle with the names, you're like, "Well, I don't like for profit [??], because obviously it's going bankrupt because of the administration [hates] and blah blah." The problem is that you're going to kick out a lot of the names end up driving all the returns. The reason they're cheap is because everyone's thinking like that, that's also the reason why you're going to probably end up [inaudible 15:37] returns on them, is because people beating them down so much. So one of the things that, I hope, that a research does and what TurnKey's all about is saying, "Hey, if you're going to do quant, just do it and don't think about the individual names as much, just think about the process and what's going into it and just take a leap of faith." And if you don't want to do that, then go be standard, fundamental investor where you go do your D side and do your homework, know everything about a company, in case you're looking at bets, but make sure you take them very well because, you're going to have to ride on only a few stocks. Or you can [inaudible 16:17] third alternative, if you can't do  what it takes to be a good  fundamental investor, you can't do what it takes to be a good quant investor, just [punt on both] and go to Vanguard and buy SP 500 index fund. Zack: I'm so happy you said that because, not the last piece, but the piece about Greenblatt because I wrote about this exactly in my book. I read in an interview somewhere with him and people were questioning why he put the Magic Formula online, he wrote a book explaining it all and someone asked and they said, "Well, once you put it online, don't you think, sort of the Alpha's going to go away," to whatever opportunities are there are going to get arbitraged away? He said, "No way because individual investors can't stick to quant strategies." And so true, right? From a behavioral point of view? Wes: Exactly. It's so hard and every time you're not [inaudible 17:09], obviously we're trained, that's what our game is but we rarely think [inaudible 17:16], if you didn't really have faith in quant and you didn't believe in it, it'd be so tempting to try to go in here and ferret out what you really want to hold, but then you just really destroy the whole point of quant which is to pull out, emotion, behavioral problems that all of us have. Yeah, it's, I don't know. I hope we can try to emphasize to people that the whole benefit of this is being objective and just doing it, because if you start meddling in, now you're going to start suffering from your behavioral biases everyone has. Hopefully we can get a process going through my research and the blog and what you do on your website and stuff. Zack: I think I read somewhere also that you served in Iraq, is that true? Wes: Yeah. I was in, serving in the Marine Corps for four years. I was an Intelligence Officer and I got opportunity to live with Iraqis, with [inaudible 18:14]. It was an interesting experience, I was part of the We Stand Up So They Can stand Down, and I have a book on the subject, if you Google that, it's called Embedded. Zack: Oh yeah? You wrote a book on it? Wes: Yeah. I wrote a book. Like I said, it's called Embedded. Wasn't a New York Times best seller but it was, it was, the basic thesis of the book is, when I went in, I was actually pretty gung ho and thought, "Hey, this is a great opportunity." My basic realization coming from that place  was that culture matters. There's actually a really good book that's titled that and, in my opinion, culture is everything and you can walk a horse to water and say, "Hey, this is a good way to do it," but if their way is better and who's to say their way is not better, they're not going to change, so I just feel like we waste a lot of time and resources and money on a lot of international escapades that, [inaudible 19:19] bankrupt, I'm sort of sounding Ron Paul. I actually kind of believe the guy, it makes so much sense after living through it, I'm like, "God.  What the hell are we doing in these places?" I could go on a whole other interview on foreign policy but [inaudible 19:39] Zack: That's awesome. I don't want to touch politics with a 10 foot pole. One question I ask all participants on the show is, you're doing tons of research and you're incredibly prolific, I have to hand it to you. I love reading everything you write. Where do you go for your own research? If you're thinking about investing on your own, are there resources online or offline that you find particularly useful? Wes: Yeah. There's a guy's website, it's CXO Advisory. It's really good. I search around [inaudible 19:19] all the time. I got a team of guys that works for me, that's their job is to just go search the web and follow professor websites and Google around constantly, just trying to catalog everything that's out there. Actually, one thing we do, some stuff we obviously keep in house but the vast majority [inaudible 20:29] world, if you, you have to pitching my own book. Kind of like the [inaudible 20:34] guys. It's free. You can just log onto TurnKey then you set up an account. We have a little module called Academic Alpha and it's literally our database where it summarizes in easy to understand format, what a particular research piece says. You can obviously Google for the paper and go read in more detail. I think we've got like 80 or 90 papers up there where, if you just want to see 80 or 90 ideas that could potentially make you money, we have them up there and, again, fulfill its mission statement of marketizing quant and it's, I think it's a great place to learn and we just provide it because we're already doing all of it and just want to [inaudible 21:18]. Zack: And you have a premium version of your website also? Something people pay for? Wes: We have, we have [DocuPay], we have a readers distribution contract with Merchant. Right now we set it up where it's, we used to have to do a flat fee, which was killing us, so now we set it up on a revenue sharing basis. Basically, if you want to get more access to the data from the long short and actually use the tool for smaller names and this sort of stuff, then we have it starting, think it's like 30 bucks a month, or something like that. But most of the material, especially like the research and ideas and the baseline stream capabilities on big stocks, it's free. We just have to charge some sort of amount to cover our baseline costs. For people that want to actually really churn on the database, because server space also it's not that expensive, but we're not a non profit, we got to at least not lose money on TurnKey. So for people that really want to use it and hammer on the databases and servers a lot more, that's why we have it bifurcated out where it's free and then there's the pay guys. Zack: I guess, one last question I have and we can end on this, it gets back to a question I asked you initially is, if there's some type of conflict of interest, and I'm not trying to dig up dirt or anything, but the fact that you have one foot in the commercial world and one foot in the research world, if you find something that's very useful, you may not publish that right way or you may not publish that forever. Is that a new model? Wes: It's actually a very old model and BioTech's been doing it for, I don't know, a long time. Look at Cambridge, Massachusetts, that's exactly just a perfect, in Stanford, Palo Alto, same thing and it's actually like what the academic is supposed to be. That's why the government funds academic institutions because they're supposed to help provide research and capability that theoretically makes the world better off and develops better products. It's weird to me that no one's ever done that, and a lot of people actually have, I think, now, just built the same sort of model in, with finance. It's not a pure science but it's the same concept, you can do an R&D in academia and then you write your paper, publish a lot of it but for a lot of stuff that may be really spectacular, why not go try to make a few bucks off of it? The reality is that doesn't happen now, because as Greenblatt said, most of it's out there in the public domain, it's just the problem is quant, it sounds easy on paper, but to actually do it in practice is not easy and there's with execution, communication, data, your behavioral problems, I wouldn't say it's a conflict of interest, I'd say it's just a model that's pretty much been out there in every single other subject, just finance hasn't really grown with the concept, I guess. I'm not really sure why but that's what our firm's all about is this arbitrage between the two worlds. Zack: I think that's awesome. Wes Gray, thanks so much for joining us. I appreciate your time. Wes: No problem, Zack. Appreciate your time and have a great day.
