We are deluged with information. Richard Saul Wurman, the godfather of information architecture, calculates that there is more information in a single issue of The New York Times than the average citizen in the 17th century would have been exposed to in his lifetime. And that calculation doesn’t even take into account the proliferation of new technology and the explosion of information available through new media. The issue is particularly acute for investors, who can access up-to-the-minute stock quotes on their iPhones, check the value of their portfolios on an iPad and choose from a multitude of television shows, magazines and newspapers to bathe in the information stream of financial markets, economies and politics. Shortage of information isn’t the problem: shortage of insight is.

Recent years have offered no respite from these maladies, and the future looks no more likely to. Recently, fiscal cliffs, debt ceilings, European crises, market volatility and political dysfunction all competed for investors’ attention, making it increasingly difficult to glean meaning from a cacophony of headlines. Today the worries are about a Chinese slowdown, a plunge in commodity prices and interest rate increases by the Federal Reserve. This distinctly modern challenge is known as information overload, a condition where the presence of too much information obscures what is genuinely important, leading either to the inclination to react to each and every new data release, or, at the opposite extreme, do nothing and succumb to paralysis. Clay Shirky, a thinker and writer on the broad subject of the role of technology in society, claims that there is actually no such thing as information overload, only filter failure. So what filters should investors have in place to enable them to hear the signal through the noise and not be distracted to their own detriment?

We offer in the following pages a series of related bedrock beliefs that help guide our own thinking about investing, whether at the level of asset allocation, security selection or the identification of third-party managers we engage to help manage our clients’ assets. We believe that these investment tenets are important in any environment but critical in one characterized by heightened uncertainty.

Risk is not volatility.

One of the cornerstones of Modern Portfolio Theory is that risk is defined as volatility and that the primary objective of portfolio management is to minimize that risk for a particular level of desired return. On initial consideration this makes sense, as exaggerated volatility of market returns is certainly unappealing to most people. Yet on second thought, most investors like upside volatility – it’s the downside volatility they can do without. So we find that the fundamental assumption of Modern Portfolio Theory is imperfect at best, and one that we do not share. Make no mistake – volatility is not a desirable state of affairs, but in our opinion the real definition of investment risk is the possibility of permanent loss of capital: losing money and not getting it back.

Indeed, for the disciplined investor, volatility is an essential contributor to investment success. Price volatility creates the opportunity for a patient investor to acquire a security at an appropriate discount to intrinsic value.1 That discount creates a margin of safety,2 or a valuation cushion, should unanticipated changes occur, either at the level of the company or issuer, or in the broader investment environment. At the same time, upside price volatility requires the discipline to sell securities – even ones with good fundamentals – if a rally pushes the price beyond the intrinsic value of the asset.

If anything, a lack of volatility can also present a serious risk, as it indicates a degree of complacency that can magnify the reaction of a market or specific security to adverse developments. As an example, consider the long stretch of price stability that characterized the equity market just before the onset of the Great Recession. On average, the S&P 500 experiences about 22 days a year in which the index moves by more than 2% in either direction.3 From 2004 through 2006 – a three-year period – the market only had two such days. Complacency reigned as imbalances built, bubbles inflated, and investor sentiment implied that nothing could go wrong. Of course, with the benefit of hindsight we know that a lot did go wrong, and the market’s complacency in advance of that exacerbated the severity of the bear market that followed. We are reminded of Warren Buffett’s admonition that investors should be greedy when others are fearful but fearful when others are greedy.

Price volatility may be uncomfortable and undesirable, but it’s not the best definition of investment risk, and it can even act as a complement to a value-based approach to investing.

Price and value are different things.

The concept of price has wonderful characteristics: it has the advantages of availability, transparency and frequency. Functioning markets and rapid reporting mean that we can usually all agree on the price of a security. Prices change constantly, and those changes are updated instantly on a variety of pricing sources, widely available to professional and personal investors alike. The problem with prices, as outlined in the previous section, is that they can be quite volatile.

Value, on the other hand, has the mirror attributes of price. Value is not transparent, available or frequent, but because of that enjoys less volatility. Whereas an investor can watch the price of a stock change throughout the course of a trading session, the value of the underlying company is only derived through patient and careful analysis and is therefore a far more robust notion than price. Benjamin Graham elegantly framed the distinction between price and value by noting that in the short run the market is a voting machine, whereas in the long run it is a weighing machine. The “votes” of countless traders determine price day to day, and second to second. Weighing the underlying economic viability and free cash flows generated by a business determines value, a far more durable concept. Investors primarily interested in the preservation and growth of their wealth over the long run are better off focused on value than price for precisely these reasons.

Price and value are obviously interconnected concepts, but investors should keep the relationship in perspective. Investing based on value acknowledges the volatility of prices but further recognizes that price volatility merely creates the opportunity to acquire fractional shares in a business at an appropriate discount to the underlying value of the company. An investor who makes price her sole or primary investment variable is like a man searching for his missing car keys underneath a street lamp because the light is better, not necessarily because the keys are there. Price is transparent, but true value is rarely discovered underneath the street lamp.

Investors must know what they own.

In order to assess the risk of permanent impairment to capital or the intrinsic value of an investment, an investor first must understand it. This requires significant research into the security, enterprise and industry under consideration for a direct investment or a deep understanding of the investment philosophy and approach when engaging a third-party manager. Without knowing what you own, it is nearly impossible to handle the information overload – to distinguish between developments that meaningfully affect the intrinsic value of the underlying investment and those that merely move the price for a shorter period of time. Even if the distinction can be made, without a deep knowledge of the investment, it is challenging to determine whether a price movement adequately reflects a possible change in underlying value. In the absence of this insight, volatility ceases to be an opportunity and becomes an enemy once again.

There are at least two strong implications that follow from the idea of knowing what you own. First, it does not make sense to invest in securities or portfolios where you don’t have visibility into the investment rationale, process or holdings. When performance is weak and very little is known about the underlying causes, what is an investor to do? Buy more because it’s cheap? Sell before it falls further? Ignorance of the underlying fundamentals leaves only emotion as a driver of action, and hope and fear make for poor investment strategies. We prefer to rely on analysis and conviction when others are buying and selling based on emotion.

Second, holding too many investments prevents an investor from knowing them well enough. Portfolios should be appropriately diversified but can easily become overdiversified, thereby introducing the risk of not developing adequate knowledge of and conviction in what is owned. Maintaining a degree of concentration in the number of investments allows an investor to dig deeper into each one, which will serve her well when price volatility inevitably tests her convictions.

There is no such thing as passive investing.

In an attempt to avoid underperforming the market over any time period – short or long – many investors shun active investing in favor of the apparent safety of passive, or index, investing.


Let’s consider the success of an index approach in fulfilling the objective of preservation and growth of wealth. The preceding graph depicts the track record of the S&P 500 Index (by far the most popular passive strategy) since the beginning of the 21st century.

From December 31, 1999, through January 28, 2016, the S&P 500 Index provided a compound annual return of -3.6%. Performing in line with the equity market over this 15-year period qualifies as a Pyrrhic victory at best, as it left an investor’s equity portfolio with only a 1.9% real return after taking inflation into account. Furthermore, human nature being what it is, the temptation to sell into weak markets and add into strong markets would have likely resulted in even worse results for most investors. Volatility may not be the best definition of investment risk, but it is a powerful motivator to act, whether justified or not.

There is, furthermore, no such thing as truly passive investing. Investors naturally assume that a passive approach avoids the necessity of determining which strategy is best suited to their needs or is best positioned to provide good returns. In an attempt to avoid making the wrong decision, an investor may decide to make no decision and invest passively. But no decision is still a decision, as there is no strategy-less investment approach. Index funds are designed to replicate the returns of a passive index, most of which are constructed based on market capitalization. The larger a company is (where market capitalization is defined as price per share times the number of shares outstanding), the bigger its weight in an index, and the more of it a passive investor, or index fund, needs to buy to ensure replication. And the more of it an investor buys, the more upward pressure there is on the price, the more the market capitalization grows, the larger its weight in the index … you can readily see where this iterative exercise leads. To the degree that most passive approaches are built on market capitalization-weighted indices, they are, at their essence, price momentum strategies. That works fine in a bull market, but unfortunately, price momentum works in a bear market as well, and this downward price momentum helps to explain the cyclical bull and bear swings shown in the preceding graph.

The good news about passive investing is that it allows you to access a price momentum strategy relatively inexpensively. Index funds are cheap to own, but, as is always the case, (and here’s the bad news) you get what you pay for, and you pay for what you get. We prefer to employ investment strategies that rely on fundamental analysis and the identification of value, rather than depend on price momentum.

Preserving wealth is the first step toward growing it.

The core principle of wealth management at Brown Brothers Harriman is that the ultimate objective of investing is the preservation and growth of our clients’ wealth. There may seem to be two goals embedded within that one statement, but preserving and growing wealth aren’t two different things, or two different pursuits – one is a necessary condition for fulfilling the other. A focus on wealth protection isn’t an expression of conservativism for the sake of conservativism, but a recognition that the pursuit of growth without an appreciation for protection can lead to loss of principal.

The graph of the S&P 500 Index shown earlier demonstrates this dynamic in action. Mathematically, if your net worth drops by 50%, you need a 100% increase merely to return to the original starting point (and the broad equity market has done this precisely twice in the past 15 years). If, on the other hand, your portfolio doesn’t experience the full downside of a bear market, then you don’t even need to participate fully in the rebound in order to regain and exceed (there’s the growth part) your original portfolio value. Stated more colloquially, if you don’t dig a hole as deep as the market, you don’t need as long a ladder to get out.

We find that the best way to express this belief in building portfolios is, as mentioned earlier, investing at a discount to the intrinsic value of the investment in order to create a margin of safety. This calls for both patience and fortitude on behalf of investors, as, for all of its benefits, value often proves to be a poor tool for timing precise turns in a financial market. Securities that are undervalued can remain so for extended periods of time, while overvalued securities can become more so in momentum-driven markets. Nevertheless, we find that valuation is as close as it gets in the investment world to a law of gravity.

There is a difference between wealth and money.

… and the difference is purchasing power. It is easy to overlook this simple observation in a period of modest inflation, but for longer-term investors, inflation stands as the most persistent threat to the goal of wealth preservation and growth. At the end of the day, it is not how much money you have that counts, but what goods and services that money can acquire.

First of all, not all inflation is created equally. Each of us has liabilities (mortgage payments, tuition bills, the desire to travel, lifestyle maintenance, retirement, charitable intent, etc.) that we look to support to some degree with the assets we have accumulated. Asset allocation is therefore essentially an exercise in balance sheet management: matching today’s assets to today’s and tomorrow’s liabilities. To the extent that our liabilities experience inflationary pressure, so, too, should our assets keep up with that inflation in order to keep the balance sheet balanced. The key insight here is that your own liability structure may or may not grow in line with the Consumer Price Index (currently 2.1%).4 Beating your own, idiosyncratic, rate of inflation is the key goal, and for most people that figure is subjectively higher than the CPI.

Additionally, we are concerned that today’s relatively modest rate of inflation will at some point begin to rise, exacerbating the challenge of protecting wealth in a real sense. Central banks at home and abroad have created the easiest monetary conditions any of us has ever seen, which eventually should exert upward pressure on prices. Indeed, fostering more inflation has become a specific goal of the Federal Reserve here in the United States. Furthermore, more inflation would help to ameliorate some of the fiscal challenges facing the nation, primarily by reducing the real outstanding obligation of federal debt. Inflation may be the worst enemy of the owner of financial wealth, but it is the debtor’s best friend. This is not to say that inflation would ever become the explicit policy of the United States government, but benign neglect can go a long way.

Finally, even without this future threat, investors should still take into account today’s modest rates of inflation. We are all familiar with the miracle of compound interest, how a very small amount of money, even at a very modest interest rate, can compound into a great fortune over enough time. Inflation is simply that dynamic in reverse. It’s how a great fortune, even at a very modest rate of inflation, can lose substantial purchasing power over time. As the nearby graph shows, even at a relatively low 2% rate of inflation, a dollar loses close to 40% of its purchasing power over a 25-year period.

Purchasing Power

Yes, inflation today is relatively modest. But small things matter, and if you don’t think so, try getting a restful night’s sleep in a room with a single mosquito.

Cash provides option value to an investor.

Given the combination of modest inflation and historically low yields, traditional fixed income currently plays a limited role in our asset allocation policy. Yields on high-quality municipal bonds or Treasuries are below the current rate of inflation for shorter or intermediate maturities, and we have been unwilling to extend the maturity of our fixed income portfolios in search of yield due to the exaggerated price risk present in longer-dated instruments. Instead, we have opted to keep a substantial portion of our clients’ fixed income allocation in strategic reserves, where they are invested with an eye toward a little bit of return but healthy liquidity. In light of such paltry returns on offer, why would we allocate any assets to fixed income at all, and particularly in the part of the market where there is little to no yield?

The answer lies in the option value of cash, or the ability to put money to work in more productive assets when presented with the opportunity to do so at appealing valuation levels. Liquidity, or ready access to funds, is a good thing, but good things typically have value. In a normal interest rate environment, investors can obtain both yield and liquidity in traditional shorter maturity fixed income instruments, or even cash. Money markets provided yields close to 5% as little as eight years ago. Those twin benefits of yield and liquidity are fragmented in the current environment, requiring investors to look in different parts of the market to obtain yield and liquidity. Liquidity is still valuable, and the current interest rate environment requires investors to pay for it in the form of negative real (after inflation) yields.

As illustrated earlier in this commentary, price volatility needn’t be the enemy of the disciplined, value-driven investor, as it provides the opportunity to acquire securities at a discount to intrinsic value. The liquidity associated with cash or strategic reserves provides the “dry powder” to act on these opportunities, and as such plays an important long-term role in portfolio construction. There is a critical distinction between this understanding of the role of cash in a portfolio and market timing. Market timing is the effort (usually futile) to forecast future price movements and position a portfolio accordingly. An appreciation of the option value of cash, on the other hand, offers the ability to respond to valuation opportunities as they arise and provides the freedom to hold cash instead of compromising on investment discipline in order to remain fully invested.

Diversification is an inadequate tool for managing risk.

Having defined risk as volatility, Modern Portfolio Theory goes on to propose diversification as the means of managing and minimizing that risk in a portfolio. The idea hinges on the benefit of owning assets that are less than perfectly correlated – that is, whose prices don’t move together in lockstep. A portfolio comprising assets that move in different directions winds up with less volatility than any one security alone, as some holdings are zigging while others are zagging. It’s a theory that works well on paper but doesn’t always hold true in practice, and therefore stands as a proof statement of that delightful aphorism ascribed to Yogi Berra that “in theory, there is no difference between theory and practice. But, in practice, there is.”

In practice, correlations between the price movements of securities are not static and usually even rise in periods of financial market stress, thereby diminishing the advantage of diversification. For example, holding a broadly diversified portfolio of global equities in late 2008 simply meant that an investor owned a lot of different things that went down in value. It is a perverse characteristic of most financial markets that, precisely when an investor most needs the benefit of diversification, those benefits disappear. Also, in the context of an increasingly global economy and interdependent financial markets, correlations have generally risen over time. A review of the relationship between commodity and equity prices between 2008 and 2012, for example, showed that correlations were twice as high during those years vs. longer-term periods, and what happens in Europe or Asia affects the U.S. markets (and vice versa) more than ever before. None of this is to deny the wisdom of appropriate diversification, but an investor who relies on diversification as her sole method of risk management is likely to find that protection evaporate in periods of financial crisis.

This observation harkens back to the fundamental idea that the whole point of investing is to protect and grow wealth. If that is true, then risk is not defined as volatility, but the possibility of permanent loss of capital. That risk cannot be managed through diversification alone, but only by knowing what you own and why you own it. Diversification is not a substitute for fundamental analysis. This is, furthermore, why investing with a margin of safety is so important. Owning securities at a discount to the intrinsic value of the enterprise provides a valuation cushion should unanticipated developments arise at either the microeconomic or macroeconomic level.


We believe investment success is a marathon, not a sprint, and whereas the application of these precepts may not work every time, we believe that they work over time. In fact, we believe that the investment philosophy entailed within these principles is the best way to invest. These tenets are by no means widely shared throughout the wealth management industry and are far easier to put down in print than to put into practice. Although not explicitly stated in the preceding pages, contrarian thinking and contrarian action are necessary corollaries to each of these ideas, and that’s not easy in an industry dominated by herd mentality and overwhelmed by the flow of information. It is, however, somewhat easier in a privately managed firm that is free from the distractions of public ownership, which allows for a genuine long-term investment perspective and a client base that aligns with that perspective. This is what guides us as we guide client portfolios, whether through asset allocation, security selection or the identification of other investment managers and strategies that complement our own investment solutions.
