(Last Updated On: July 14, 2017)

Our mission is to empower investors through education. This mission is our passion and what drives us to go to work everyday.

But this mission is not our product.

Our product is Affordable Alpha: We seek to deliver “alpha” (highly differentiated risk/reward profiles) at low costs, thereby giving sophisticated investors a higher chance of winning, net of fees and taxes.

Note: Here are some high-level background documents on our firm

Why Affordable Alpha?

We are based outside of Philadelphia, roughly 15 minutes from Vanguard’s campus.

Vanguard is the gentle giant of the region and we welcome their business model and vision for financial services: transparency, affordability, and disintermediation.

We also know competing against Vanguard in cheap non-differentiated, “commodity” products is a fool’s errand. Firms we greatly respect, such as DFA, AQR, and Blackrock, are learning this lesson the hard way. To us, Vanguard is like Costco. And when you need 5 gallons of Mayonnaise, there’s no better place.

But we also know that Vanguard can’t effectively compete in all areas — especially when it comes to highly differentiated, limited capacity, concentrated investments. Because of our limited size and extensive research capabilities, we feel confident in our ability to compete.

Eureka! Let Costco be Costco, and we will thrive where Vanguard can’t. But who is actually playing in this space and what are they doing? Note: if you are a hedge fund manager charging 2/20 from your yacht in the Maldives, you are not going to like the next section. Welcome to the land of “active” managers. When we looked at the active management industry we observe two key trends:

  1. Costs are too high.
  2. Not everyone is truly “active,” or genuinely different than a passive index fund. They’re essentially posers.

First issue: high costs

Today’s active manager faces a dilemma: how the heck can I get my great idea to investors? Answer: Pay someone (distribution costs). For decades, active managers have relied on distribution networks to sell, market, and advertise their products. Remember when the vacuum salesman came to your door and introduced the Suck-O-Matic into your life? You didn’t wake up realizing you needed the Suck-O-Matic, but once you saw the demo, heard the pitch, and made friends with the Sales Rep, how could not have the Suck-O-Matic in your home?

Same story with financial services. You woke up not really thinking about the GrayPebble QuantBeta Triple Arb Macro-Micro Bond Fund, but when you saw Ernie Els wearing their logo and your Financial Advisor told you how great it was, you went for it.

Today, most financial products are all sold, not bought. And sales people are extremely expensive (and persuasive!).

We decided to invert the problem. Make products that people want to learn about, understand, and approach us when it makes sense. In short, develop strategies that people want to buy, not products that sales reps want to sell. We’ll leverage our background as researchers and educators to inform the public about strategies that make sense and the right investors (sophisticated, wants to learn, etc.) can come to us. Minimize distribution costs and deliver affordable alpha-focused products.

Second issue: Closet Indexers

Just because someone says they are a value investor, doesn’t mean they are actually following a value investing approach. Going back to our CostCo example, we came across several types that were marketing gourmet French mayonnaise in tiny two ounce bottles. Unfortunately, they were actually in the back of their kitchen spooning the Costco brand mayo into fancy jars and selling it for $20 a pop! Sounds ridiculous, but we see it all the time. To ensure consumers can’t get duped, we decided to be 100% transparent with our processes. No black boxes, no mystery strategies, no secret sauce. Our two-ounce gourmet mayonnaise may not be what every investor needs/wants, but we’ll be delivering what we say we’re going to deliver and it will be priced affordably.

A firm was born. Let’s get costs contained and let’s deliver on our promise of differentiation.

We think alpha strategies can work for the investor, but they probably won’t work for a mutual fund manager, hedge fund guru, or sales rep. We can make active investing affordable, transparent, and intellectually honest.

Alpha Architect (AA) can deliver Affordable Alpha (AA):

  • Affordable: Non-scalable active strategies are scarce and expensive to produce. These products can never be priced like a Vanguard fund, but they also don’t need to be “two and twenty.”
  • Alpha: Portfolios need to be different to be differentiated. We are not closet-indexers (e.g., “smart beta”) and we build portfolios that seek to deliver unique risk and reward profiles.


Important to note: Our products will be delivered in the context of a broader mission to empower investors via education and we will adhere to our four core beliefs of 1) transparency, 2) systematic decision-making, 3) evidence-based investing, and 4) win-wins.

Understanding the Asset Management Landscape

Our hope is that the framework we outline below will allow investors to differentiate among investment management products based on a few key characteristics.

First, let’s define a few concepts that are central to understanding the investments industry:

  • Alpha: Formally, alpha represents the intercept estimate from a regression of an investment strategy against various risk-factors. In English, alpha is exposure to a different risk/return profile that may not be in  your current portfolio (which is highly valuable).
  • Tracking Error: The standard deviation between a strategy’s returns and a benchmark’s returns. In other words, how closely a portfolio follows, or “tracks,” an index. To the extent one cares about being close to a benchmark, tracking error is important. P.S. If you want to be vastly different than the market, tracking error is a positive indicator.
  • Active Share: This measure quantifies how different a manager invests compared to a benchmark. A good proxy for active share is simply the number of securities in a portfolio. For example, a manager that holds 50 equally-weighted stocks will likely have a much higher Active Share than a manager that holds 500 market-weighted stocks. High Active typically means High Tracking Error and vice versa (not always).(1)
  • Passive Index: By construction, passive index portfolios are designed to have no differentiation from the broad market. A good example of an index strategy is the Vanguard S&P 500 Index Fund. This fund does not attempt to add Alpha, but seeks to match the performance of the S&P 500 index with minimal tracking error. Here is a post on the subject.

With some basic concepts under our belt, we can now explore the asset management industry. We break the industry into three main categories:

  • Passive Index Products: Index (“Passive”) products offer no alpha, no tracking error, and no Active Share.
    • These funds, typified by Vanguard’s products, have a high number of securities, low expense ratios (<20bps), and low marketing costs. (Think about the Costco example).
  • “Closet Index” or “Smart Beta” Products: Closet Index products, sometimes referred to as “smart beta,” offer little differentiation, little tracking error, and little Active Share.
    • These funds typically have a large number of securities, low to high-level expense ratios (25-100bps), and high marketing costs. (Think Sales Rep marketing fancy mayo, but spooning Costco mayo into tiny bottles).
  • Active Products: Active products, often delivered via mutual fund or hedge fund vehicles, are characterized by high expected alpha, high tracking error, and high Active Share.
    • These funds have a low number of securities (<50), high expense ratios (75bps – 200bps+), and extremely high marketing costs.

To win in the Passive Index game one needs to be Vanguard. To win in Closet Index / Smart Beta or Active an asset manager needs to be a marketing machine. Alpha Architect is not Vanguard and is not a marketing machine. So we are creating our own category: Affordable Alpha.

  • Affordable Alpha Products: Alpha Architect products are characterized by limited scalability (a limited amount of $ can invest), high expected alpha (different), high tracking error and Active Share (don’t track a passive index).
    • These funds are backed by intense research efforts, mid-level expense ratios, and limited marketing costs.

The 4 different categories of asset management products are summarized in the table below:

All 4 categories can arguably serve the investor, with varying costs/benefits to each. We are not competing with Passive Indexers, or Closet Indexers / Smart Beta. So we will not directly comment on the validity of these approaches. Our competitive angle is squarely targeted on expensive active strategies and our mission is to make these high expected performance strategies more affordable.

What We Seek to Deliver: Affordable Alpha

Two words define what we seek to deliver: Affordable, Alpha. We will briefly describe what we mean by each of these terms. First we discuss the most important aspect of what we do: generate alpha. Next we will discuss affordability and why costs matter.

Our goal is to highlight Alpha Architect’s product goal, which is to deliver higher net returns for long-term investors in active products.


Condition #1: Be Different

Charlie Munger, at the 2004 Berkshire Hathaway Annual Meeting, is quoted as saying, “The idea of excessive diversification is madness…almost all good investments will involve relatively low diversification.” Of course, you still need to be a good investor, but the point remains: too much diversification laid on top of a good investment strategy is a bad thing. Munger calls it: “diworsification.”

Diversification is a dual-edged sword:

  • Owning more stocks can lower a portfolio’s risk profile (i.e. good!).
  • Owning more stocks than necessary can dilute performance (i.e. bad!).

The data supports Munger’s remarks: We have posts on value and momentum strategies and highlight the direct relationship between portfolio concentration and past performance.

The million dollar question: What is the optimal trade-off between performance and risk?

Let’s first tackle risk, which is broken down into two types: Idiosyncratic and Systematic.

Idiosyncratic risk is the risk we can control via diversification. Idiosyncratic risks are risks of a stock that are uncorrelated with other risks. Examples include a  building  catching on fire, a hurricane , or hiring Travis Kalanick to run your company’s gender-equality program. But idiosyncratic risk cuts both ways: a company can benefit from, say, a favorable lawsuit outcome, or a positive FDA ruling. When investors hold a large portfolio of stocks, these idiosyncratic risks–which are unrelated–cancel each other out, on average.

Systematic risks  are risks we can’t diversify away. An example might be the general economy going into a depression. If people in the economy aren’t spending money, all companies are impacted. No matter how many we hold, the risk stays the same.

To get a better sense of how increasing portfolio size affects portfolio volatility in the context of stocks we simply look to the academic literature.(2)

The figure below, highlights the relationship between portfolio size and risk. In the top left corner, we have the portfolio risk associated with holding one single company in a portfolio. In the bottom right, we have the portfolio risk associated with holding 1,000 companies in a portfolio. Most people understand that risk will decrease as you increase your holdings. What’s fascinating however, is the rapid “ski slope” shape of the graph. Notice that portfolio risk plummets as you grow from 1 to 30 stocks, declines from 30 to 50, and basically flatlines thereafter. For idiosyncratic risk, holding 50 or 1000 stocks is almost the same.

This is what diworsification is! Additional diversification beyond ~50 stocks we prevents our portfolio from concentrating on stocks we feel are “undervalued.” Warren Buffet holds a small portfolio of stocks–to ensure he doesn’t completely blow up–but he doesn’t hold 1,000 companies.

Again, let’s go to the data. Let’s take a simple high-performance value factor: EBIT/TEV (a version of enterprise multiple). There is a clear historical relationship between EBIT/TEV and future stock returns. High EBIT/TEV stocks earn higher returns than low EBIT/TEV stocks. In English, this is plain value investing (buy cheap stuff).

First, a quick description of the study we conduct from 1964-2013. We identify firms above the NYSE 40th percentile for market capitalization that have information to calculate enterprise multiples. In 2013 terms, this equates to a universe that looks at stocks with a market capitalization of ~$2B and up. With our universe of mid to large cap firms, we split firms into three differently sized portfolios based on EBIT/TEV measures: Top third EBIT/TEV (~279 stocks), Top quintile EBIT/TEV (~167 stocks), and Top decile EBIT/TEV (~83 stocks).

In the table below we display the summary statistics for the following three portfolios (here is the source):

  • EBIT Cheap Decile = Value-Weight, monthly re-balanced portfolio of cheapest 10% of EBIT/TEV stocks
  • EBIT Cheap Quintile = Value-Weight, monthly re-balanced portfolio of cheapest 20% of EBIT/TEV stocks
  • EBIT Cheap Tercile = Value-Weight, monthly re-balanced portfolio of cheapest 33% of EBIT/TEV stocks
Summary Statistics Cheap Decile Cheap Quintile Cheap Tercile
CAGR 15.72% 14.42% 13.43%
Standard Deviation 17.64% 16.02% 15.25%
Sharpe Ratio (RF=T-Bills) 0.64 0.61 0.58

The results are hypothetical results and are NOT an indicator of future results and do NOT represent returns that any investor actually attained. Indexes are unmanaged, do not reflect management or trading fees, and one cannot invest directly in an index. Additional information regarding the construction of these results is available upon request.

The results are clear: more concentration increases returns (but also increases volatility). The increase in volatility is expected (remember our ski slope graph still has lower volatility at 1000 not 50). But what should an investor choose? What is the tradeoff between returns and volatility? Answer: The Sharpe ratio.

The Sharpe Ratio is one commonly used measure to calculate the tradeoff between returns and volatility. More Sharpe = Better tradeoff between risk and return. Based on Sharpe ratios, the evidence above suggests that concentration is a better, risk-adjusted bet. You get a net performance boost by concentrating your holdings. Munger is right: to the extent you believe you have an edge, less diversification is desirable and often cheaper.

Condition #2: Have an Edge

Great, so all we need is a good strategy that works. Easy, right? Formally, alpha, or “edge,” is the intercept estimate associated with a factor regression using an investor’s favorite factor model (see here for an in-depth discussion). Informally, “alpha” can be interpreted as skill, luck, and everything in between. To some, alpha represents brains, to others, luck. To us, alpha represents an attractive investment opportunity, rooted in evidence, that is difficult to exploit for behavioral reasons. Humans are imperfect creatures. We eat cheeseburgers even though we know kale is better for us. We buy the Baywatch Collectors Edition box set rather than save for retirement. We do stupid things.

For investing, we believe extreme investor education and following a structured process can save us from ourselves. And we must. Human behavior can influence investment decisions, sometimes in ways that hurt investors. This is the central premise in behavioral finance. Warren Buffett is attributed as saying that investing is simple, but not easy. Similarly, integrating our understanding of human behavior into an investment process is simple, but not easy.

How, specifically, does our behavior impact stock prices?

Despite our best intentions, our investing approach is not always governed by rationality. In particular, our judgment and decision-making can be significantly affected by intuition, a form of abstract, automatic thinking that can override our reason. Faulty intuition and other forms of irrationality can cause us to do the wrong thing and can also create mispricings in the market. We call this behavioral bias.  One example of behavioral bias affecting stock prices is the human tendency to extrapolate short-term patterns and ignore long-term trends (representative bias). Academic research shows that representative bias likely explains part of the “value premium,” which describes the large spread in realized returns between value stocks and growth stocks.(3)

But this phenomena only confirms that there are bad investors in the marketplace. Surprise. That alone, however, will not drive stock prices out of whack. Surely there are smart people, with supercomputers, that will send these Baywatch watching, cheeseburger eating cavemen back to their basements where they belong, right?

The second building block of behavioral finance requires an understanding of market frictions, often referred to as the “Limits of Arbitrage.”(4)

To understand the two components of behavioral finance (behavior and limits of arbitrage), let’s play a simple game of poker using the diagram below:

For illustration purposes only.

On one end of the table, we have our irrational investors. They drop their cards, they giggle when they get an Ace, and they ask people next to them “Is it a good thing if all of my cards have the people’s faces on them?”

On the other side of the table is an institutional poker player, hired by wealthy investors, to play poker as best as possible. This poker player is a pure genius, mathematically calculates all probabilities in her head, and knows her odds better than anyone. Now imagine that our super player, as a hired gun, has a few limits. “We need you to maintain good diversification across low numbers and high numbers. We also want to see a sector rotation between spades, aces, and clubs. Don’t take on too much risk with straights and flushes, stick to pairs like the market does…” No one would ever play poker like this. But in finance, this is how people play.

Now the cards are dealt. Super Player sees a great opportunity with a high chance of success, but it violates all the requirements of her investors. She doesn’t bet, and sure enough, she could have won big.

The two building blocks of behavioral finance–understanding bias (bad poker players) and arbitrage restrictions (great poker player restrictions)–combine to create opportunities for savvy long-term investors. The Efficient Market Hypothesis (the “EMH”) claims this phenomena can’t exist. EMH claims that market prices reflect all publicly available information about securities. In our poker example, the Super Player will gobble up every opportunity perfectly and efficiently as they are revealed by the bad poker players. In the EMH view, prices will always reflect fundamental value–even when some market participants suffer from extreme behavioral bias. But we feel a strict interpretation of EMH is flawed, since it assumes the costs of chasing the bad poker players’ mistakes are zero. In reality, exploiting investment opportunities created by bad poker players can be very costly (e.g., if you fail to maintain diversification across spades and clubs, we will fire  you and get a different player).

In our poker example, the real path to doing well in the game is to find the right clients that will stick to a strategy. No need to sector rotate across suits, diversify away a good hand, etc. The arbitrage opportunity is marrying a good investment strategy with a good investment partner. Our investment strategies systematically exploit these opportunities because “smart money,” will typically get fired if they are given free reign to really pursue a winning strategy over the long-term. We explain this philosophy in great detail in our sustainable active investing piece. We also like to emphasize why our two biggest focus areas — concentrated value and momentum — can have terrible bouts of relative underperformance.

We also like to emphasize why our two biggest focus areas — concentrated value and momentum — can have terrible bouts of relative underperformance.(5)


Warren Buffett obliquely references the concept of affordability in the context of stock-picking:

It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price.(6)

Most people understand the concept of affordability when they shop at the grocery store, but lose sight of it when they shop for financial services. Let’s look at an example below with three shopping types. Our Expensive Shopper (green line) really likes Goldman Sachs because it’s awesome to tell the ladies at the cocktail party that you bank with Goldman Sachs. Let’s even give them the benefit of the doubt that they outperform, but they pay 1.5% all in. A cheap shopper (blue line) only focuses on price. Finance is intimidating, we don’t want to invest all of this time in learning the nuance and methods, let’s just go to CostCo and get the cheap stuff. Perfectly reasonable. Now let’s examine an “affordable” shopper that can follow a disciplined strategy, but pays a little more. The figure below highlights why being an affordable-minded consumer of financial services can be a good financial decision for those that want to learn the difference in what they are investing in. Our Goldman Sachs shopper fared poorest in his portfolio over time. Our cheap shopper did better, but our affordable investor, who weighed costs AND benefits, came out on top.(7)

The results are hypothetical results and are NOT an indicator of future results and do NOT represent returns that any investor actually attained. Additional information regarding the construction of these results is available upon request.

This all sounds great, but one question remains:

How can we deliver high value services at lower costs than the competition?

We deliver affordability by reinventing the way business is done in financial services:

  • We seek to minimize distribution costs. Intermediaries should add value, not extract it.
  • We leverage technology to maximize efficiency. “Computers good, people bad.”(8)
  • We maintain a culture of doing more with less.(9) In other words, you’ll find us driving Honda Civics, not Ferraris.

Over time, other asset managers will evolve to embrace technology and perhaps they will give up on high-priced overhead. At least one would hope. But the real disruption in financial services revolves around distribution and going direct to consumer (e.g., individual investor or their advisor). Distribution is currently extremely expensive and the clients foot the bill eventually. This model relies heavily on an intermediary. Let’s look at the Old Model in the figure below.

First, an asset manager develops an investment strategy ( “Strategy”), which is distributed by some means (labeled “Distribution”) to the investment public (labeled “Consumer’). A well-intentioned asset manager that wants to charge 75bps could be faced with a 75bps distribution fee, making the total product cost 150bps, or 1.5%. Half of the total fee goes to middleman sitting between the Manager and the client. The consumer pays twice: once for the development of the strategy, and once for a middleman. This is the status quo for today’s financial products.

One thing is certain: The asset manager and the consumer would both be better off if they could cut the middle-man out. The client would save 75bps in fees and the asset manager would have direct access to the client. The direct-to-consumer model (AA Model) represents where we think the future of the financial services is headed. No middlemen, less conflicts of interest, more affordability.

How do we go direct to consumer?

We focus on inbound marketing. We tell people what we do, why we do it, and how we do it, and they reach out to us for information and education (see our active robo as an example). Our products are designed to be bought through genuine client interest, not sold via middle channels. Our approach efficiently taps into a self-selected group of investors who understand and appreciate our value proposition.

As alluded to earlier, minimizing distribution costs aren’t the only way we can minimize costs. Our dedication to low-cost infrastructure and reliance on technology ensures our viability as a going concern. In short, we run things cheaper and more efficiently than your average active manager.  Sure, we would love to have box seats at Yankee Stadium, host wine and cheese events for our investors on the company yacht, and have three assistants for every employee.But we all know these things don’t add value to an investment portfolio. They merely add costs to the client. The money would be better spent on research and development or on technology to improve our offerings.



We believe that financial services will be more competitive, transparent, and client-friendly in the future. We want to be on the forefront of this new normal in investment management. Our particular focus is on the active management sector and our desire is to create a new category: Affordable Alpha. Alpha Architect seeks to generate higher net returns for long-term buy-and-hold investors.

In order to have confidence in our approach, which is unique and highly differentiated from others, one must understand our investment processes and the research behind them (our books and blog posts are a great place to get started).

We believe our approach to the markets makes sense for sophisticated, long-term, disciplined investors. They don’t want the generic passive indexes or closet-indexing funds. We call these investors “sustainable clients.” The central belief behind our “edge” is that we can couple patient and disciplined capital with innovative strategies. It all boils down to educating clients and making them better investors. And we should all want that.

About the Author

Wesley R. Gray, Ph.D.

After serving as a Captain in the United States Marine Corps, Dr. Gray earned a PhD, and worked as a finance professor at Drexel University. Dr. Gray’s interest in bridging the research gap between academia and industry led him to found Alpha Architect, an asset management that delivers affordable active exposures for tax-sensitive investors. Dr. Gray has published four books and a number of academic articles. Wes is a regular contributor to multiple industry outlets, to include the following: Wall Street Journal, Forbes, ETF.com, and the CFA Institute. Dr. Gray earned an MBA and a PhD in finance from the University of Chicago and graduated magna cum laude with a BS from The Wharton School of the University of Pennsylvania.


    Nice work Wes. Compelling thesis. I was listening to Charley Ellis today on Capital Allocators Podcast. He’s adamant that alpha has all been arbed away by technology, MBAs, CFAs etc. There are too many smart people in the market chasing alpha; of course not saying you are not smart but with 85% US and 87% UK fund managers failing to beat their benchmark over the medium to long term, one wonders if firms can eek out any alpha net of associated costs in finding that edge/alpha in the first place? Have you read ‘Looking for Easy Games’ Jan 4 2017 by Mauboussin ? The paper recommends Active managers, ‘be active’ and invest in their best ideas; think long term; and, use quantitative methods (he must be a fan of yours!). Best of luck with the approach/strategy

  • This is something I think about all the time. The hypothesis is compelling.
    I’ve got a fairly extensive post I’m working on that will discuss this hypothesis. I think there are cracks in the assumptions.
    First, smart people chase alpha. That is debatable and the principal/agent conflicts are getting more extreme. See here: http://blog.alphaarchitect.com/2017/04/26/academic-factor-exposure-versus-fund-factor-exposure/
    Second, capital is overwhelming factors. See here: http://blog.alphaarchitect.com/2017/02/17/will-etfs-destroy-factor-investing-nope/
    Third, the set of active managers studied are representative of high active share, highly differentiated active managers doing something different.

    All that said, the mega-cap size factor fund with a beta =1 has paid the highest premiums over the past 15 years, on average. No doubt about that. Will that continue in the future? Who knows. But I’d guess that won’t be the case over the next 15-20yrs


    Thanks Wes; looking forward to the lengthy post. If the robots have their way and the ultimate aim of capitalism is to drive down costs ( greater automation, lower fixed wage costs) one wonders how the investable universe and associated capital levels might change in the future!

  • This old chart from Geczy’s/Samanov paper is pretty puzzling for the “technology/smart people are driving premiums to zero” hypothesis. One would need to argue that in the 1850’s everyone figured out momentum investing, put their super-computers in place, and decided to destroy the premium. That seems like a stretch. Perhaps the reality is these premiums are driven by risk factors and/or systematic mispricing that is really hard to arbitrage. That hypothesis seems more credible.
    Anyway, these are competing hypothesis that can and should be discussed. I’m on the ‘extra risk + tough to arb mispricing” fence. But could be wrong. Maybe the markets are perfectly efficient these days, both on a short term basis and a long-term basis.
