Inflation Risk

Wed, 10 Nov 2010 14:06:55 EST

As the capital markets have improved, more investors have shifted their concern from weathering the financial crisis to anticipating the inflationary effects of rising federal spending and debt. Many people are asking how they can prepare for potentially higher inflation. We will explore two basic ways to address inflation uncertainty and highlight asset groups that may prove useful.

As you consider strategies, remember the difference between expected and unexpected inflation. Asset prices already reflect the market’s expectations about future inflation, given all available information. Inflation may turn out to be worse than expected, and this risk of unexpected inflation is what some investors may want to manage.

Hedging vs. Total Return Strategies

Investors can prepare for unexpected inflation by following one of two basic strategies—hedging the immediate effects of inflation or earning a total return that outpaces inflation over time.

Hedging involves choosing assets whose value tends to rise with inflation. Although holding these assets may reduce the total return of a portfolio, the positive correlation with inflation can help an investor keep up with rising consumer prices, at least over the short term. (Correlation refers to the co-movement of asset returns. When two assets are positively correlated, their returns tend to move together; when negatively correlated, their returns are dissimilar.)

Candidates for hedging include retirees, fixed income investors, and others who would experience a diminished living standard during an inflationary period. These investors are willing to forfeit long-term growth potential for more immediate inflation protection.

In a total return strategy, an investor attempts to outpace inflation by holding assets that are expected to earn higher real (inflation-adjusted) returns. This investor is willing to give up short-term inflation protection for an opportunity to grow real wealth. Younger investors are typically well suited for this strategy because they have many years until retirement and expect their earnings to advance faster than the inflation rate. As they save and invest for the future, they can accept more risk through greater exposure to higher-return assets, such as stocks.

To insulate a portfolio from unexpected inflation risk, both strategies may employ some combination of stocks, short-term fixed income, and Treasury Inflation-Protected Securities (TIPS). Let’s consider each:

Stocks

Equity securities have provided a positive inflation-adjusted return over the long term. From 1926 through 2008, the total US stock market, as measured by the CRSP 1-10 Index, outpaced inflation by an average of 6.16% per year. To achieve this higher expected real return in stocks, however, an investor had to accept more risk, as measured by greater volatility in returns, and endure periods when stocks did not outpace inflation. As a result, stocks may be less effective for hedging short-term inflation and more suitable for investors who want to beat long-term inflation by earning a higher total return.

Some investors assume that high inflation leads to lower stock market performance, while low inflation fuels higher stock returns. In reality, inflation is just one of many factors driving stock performance. US market history since 1926 shows that nominal annual stock returns are unrelated to inflation.

Fixed Income (Bonds)

Higher inflation can hurt bondholders in two ways—through falling bond market values triggered by rising interest rates, and through erosion in the real value of interest payments and principal at maturity. This inflation exposure tends to impact the prices of long-term bonds more than those of short-term bonds, and investors can mitigate the effects of rising interest rates by holding shorter-term instruments.

Many types of investors may benefit from holding short-term bonds. When interest rates are climbing, a portfolio with shorter-term maturities enables an investor to more frequently roll over principal at a higher interest rate. This can help inflation-sensitive investors keep up with short-term inflation and enable total return investors to reduce portfolio volatility, which can lead to higher compounded returns and growth of real wealth.

Treasury Inflation-Protected Securities (TIPS)

Issued by the US government, TIPS are fixed income securities whose principal is adjusted to reflect changes in the Consumer Price Index (CPI). When the CPI rises, the principal increases, which results in higher interest payments. At maturity, an investor receives the greater of the inflation-adjusted or original principal. The inflation provision enables TIPS to preserve real purchasing power and hedge against unexpected inflation.

TIPS are generally a good short-term inflation hedge since principal is adjusted for changes in the CPI. They are also a good portfolio diversifier for some long-term investors due to their negative correlation with equities and relatively low correlation with most types of fixed income assets. TIPS were introduced in 1997, so these correlations are based on a relatively short sample period.

However, keep in mind that TIPS prices also have been affected by changes in real interest rates, so TIPS may not track inflation one-to-one in the short term or over longer periods of time. In fact, TIPS can lose market value if real interest rates increase.

Commodities

Commodity futures, as well as gold and oil, are perceived as effective inflation hedges because their returns are positively correlated with inflation. But commodities are more volatile than stocks, and their returns do not always rise with inflation because of this significant volatility.So adding these assets to a portfolio may increase real return volatility, which could offset the benefits of hedging.

Investors should also consider the economic argument against holding commodities. Unlike stocks, commodity futures do not generate earnings or create business value. They are essentially a speculative bet in which there is a winner and loser at the end of each trade. Moreover, a broad-based stock portfolio already has significant commodity exposure through ownership of companies involved in energy, mining, agriculture, natural resources, and refined products.

Summary

While the media have featured divergent opinions and theories about the effects of recent government actions on inflation, no one really knows how consumer prices will respond to the complex forces at work in the economy and markets. We should carefully review your financial circumstances and investment goals before making changes to your portfolio.

As you assess your exposure to a high-inflation scenario and form a strategy that reflects your financial goals and risk tolerance, consider that:

Expected inflation is built into asset prices. In my view, markets efficiently integrate all known information into prices. Thus, current prices already reflect expectations of future inflation. Only unexpected news will affect the inflation outlook.
Hedging unexpected inflation has a cost. Investments traditionally regarded as effective short-term inflation hedges have lower historical returns than stocks—and some have much higher volatility.
Volatility matters. Evaluating assets solely on their ability to track inflation disregards the effect of volatility on returns and risk. Some assets that are positively correlated with inflation have large return variances, and adding these to a stock and bond portfolio may increase overall volatility.

Even with the prospect for higher inflation, investors who take a total return approach may be better served than those who choose assets based on correlation with the CPI. By choosing assets with higher expected long-term returns and maintaining broad diversification, investors can seek to grow real wealth and preserve the purchasing power of their dollars.

Fixed Income Risk

Wed, 10 Nov 2010 14:03:20 EST

With interest rates near historical lows, some investors may be anxious about a possible rate climb and its potential impact on their fixed income investments. Rising interest rates typically cause existing bonds to lose value. While investors might hold short-term instruments to manage this risk, an interest rate decline could spoil this strategy by forcing investors to reinvest in lower yields when their short-term instruments mature.

Rate movements in either direction affect portfolio returns. This is true in any market environment, regardless of the current rate level. The larger question is how to manage the risk. As you read the financial headlines and evaluate your current fixed income exposure, it may be helpful to consider these principles about fixed income investing:

Interest rate movements are unpredictable.

Academic research offers strong evidence that the bond market is efficient, and that bond prices and interest rates are not predictable over the short term. This uncertainty is reflected in the often-contradictory interest rate forecasts offered by economists, analysts, and other market watchers.

Even when the experts share similar views on the direction of the economy and credit markets, reality often proves them wrong. Last year’s Wall Street Journal forecasting survey offers a recent example. Among fifty economic forecasters surveyed in 2009, forty-three expected the ten-year US Treasury note yield to move higher over the next year, with an average estimate of a 4.13% yield. Only two respondents predicted rates to fall below 3.00%. The ten-year Treasury yield slumped to 2.95% on June 30, 2010, and rates on thirty-year mortgages fell to their lowest level since Fannie Mae began tracking them in 1971.

Today’s bond prices already reflect expectations for tomorrow’s business conditions and inflation, and these expectations can change quickly in response to new information. This new information is unknowable. Investors who accept market efficiency should not be surprised when the credit markets foil the experts. If prices were easy to forecast, you should find a host of fixed income managers with market-beating returns. But most of them underperform their respective benchmarks over longer time periods.

Since no one has a reliable method for determining whether interest rates will rise or fall in the near future, investors should avoid making fixed income decisions based on a forecast, media coverage, or their own hunches.

Pursuing higher expected returns requires more risk taking.

The strong link between risk and return appears in all properly functioning capital markets. When investing in stocks, bonds, or other assets, investors must accept more risk to pursue a higher potential return.

In the fixed income markets, earning a return above short-term government instruments is usually a function of assuming more term and credit risk. Term risk refers to a bond’s maturity, and credit risk refers to the creditworthiness or default potential of the borrower. Bonds with longer maturities and lower credit quality are usually considered riskier and have offered higher yields and returns to compensate investors for higher risk.

On the term side, investors who commit their capital for longer periods of time are exposed to the amplified effects of changing interest rates. Bond prices and interest rates move in the opposite direction: When rates rise, the value of an existing bond declines; when rates fall, bond values rise. The market adjusts the price to match the yield available on a new instrument. The longer the bond’s maturity, the greater the price adjustment for a particular interest rate change. A long-term bond is more exposed to rate changes than a short-term instrument, and usually (but not always) offers a higher yield to compensate investors for the extra risk. Also, lower-coupon bonds are more affected by interest rate changes than higher-coupon bonds. For example, if rates move 1%, a bond that pays 3% will experience a greater gain or loss than one paying 5%.

On the credit risk side, the government is considered the strongest borrower in the market, so it has a lower cost of capital relative to other issuers. The most creditworthy companies are considered relatively safe, but they must still offer a higher rate than the government to compensate investors for taking more default risk. The weaker a corporate borrower’s financial condition, the more it must pay in yield to attract investors. Investors seeking higher returns on the credit spectrum must bear a higher risk of default.

Overall investment strategy should drive fixed income decisions.

Investors may hold fixed income securities for a variety of reasons—for example, to reduce portfolio volatility, generate income, maintain liquidity, pursue higher returns, or meet a future funding obligation. Each objective may involve a different portfolio approach, or a combination of strategies to manage tradeoffs. For example, investors who want to maximize current income may not be strongly concerned with the effects of short-term price volatility. They may extend maturity or accept slightly lower credit quality when the market offers a yield premium for doing so. On the other hand, investors seeking long-term wealth appreciation may commit most of their portfolio to equities and keep their fixed income investments short term and high quality to buffer the volatility of stocks.

Regardless of your approach, you should know the difference between controlling risk and avoiding it. You cannot eliminate risk, but you can manage your exposure by diversifying across maturities, industries, countries, and currencies to reduce the impact of rates, inflation, currency fluctuations, and other risks. Your decision to take more term and default risk may depend on the current state of the yield curve and credit spread.

Many factors influence the direction of interest rates and performance in the bond markets, and these are too complex for anyone to reliably predict. Rather than placing your faith in the experts or reacting to economic news, manage your fixed income component from a portfolio perspective. Your strategy should reflect your overall investment goals, risk tolerance, and other personal financial considerations. This is a solid approach to managing your portfolio in an uncertain interest rate market.

The Stock-Bond Decision

Wed, 10 Nov 2010 13:58:55 EST

Choosing a basic stock-bond mix is an important first step in portfolio design. Although the decision may appear simple, it can have a profound impact on your wealth.

Portfolio theory explains the value of making a deliberate, strategic decision about the proportion of stocks versus bonds to hold in a portfolio. This decision has roots in the “separation theorem,” which was proposed by Nobel laureate James Tobin in the late 1950s. The separation theorem proposes that all investors face two important decisions: (1) deciding how much risk to take, and then (2) forming a portfolio of “risky” assets (stocks) and “less risky” assets (bonds) to achieve this risk exposure. Your stock-bond decision implements this risk position.

The Rationale

The separation theorem proposes that all investors who are willing to take stock risk should begin with a diversified market portfolio. Each investor then can dial down total risk in the portfolio by adding bonds to the mix. The greater the bond allocation relative to stocks, the less risky the portfolio and the lower the total expected return; the greater the stock allocation relative to bonds, the higher the portfolio’s expected return and risk.

Investors who want to take even more risk than the market can increase exposure through borrowing on margin and/or tilting the stock portfolio toward asset groups that offer higher expected returns for higher risk (small cap stocks, value stocks).

So, how does one confidently allocate between stocks and bonds? A common method is to evaluate model portfolios along the risk-return spectrum. A riskier portfolio holds 100% stocks, and the least volatile portfolio holds 100% bonds. Between these extremes lie standard stock-bond allocations, such as 80%-20%, 60%-40%, 40%-60%, and 20%-80%. Then you compare the average annualized return and volatility (standard deviation) of each model portfolio for different periods, such as one, three, five, ten, and twenty years. Volatility is one of several risk measures investors may want to consider. With this in mind, the analysis should feature average returns, as well as best- and worst-case returns for the various periods.

While this technique relies on historical performance that may not repeat in the future, and does not consider various investment costs, it helps you think about the risk-return tradeoff and visualize the range of potential outcomes based on the aggressiveness of your strategy.

Another method involves the so-called "age in bonds" rule of thumb, espoused most notably by Vanguard founder and retired CEO John Bogle.

In my opinion, age is the best determinant of an investor's capacity to take risk. Younger investors typically have higher levels of human capital (total future earnings) relative to the value of their current investment capital. They have the ability to take on more stock exposure because they have the ability to make up for stock market setbacks with regular earnings/savings. They simply have time on their side. If human capital is more “bond-like,” such as having a stable career with a salary similar to a bond paying a coupon that increases with inflation, then more investment capital can be allocated to stocks. As the investor gets older and the investment capital becomes larger relative to human capital, the investment side takes on more bond exposure that has been lost with declining human capital.

If we use the age in bonds rule as a logical starting point, it can then be modified, within reason, by your personal tolerance of risk. Here’s one way to look at it:

Risk Tolerance	Adjustment	Example for Age 50
Very High	+20%	70/30 stock/bond
High	+10%	60/40 stock/bond
Moderate	0%	50/50 stock/bond
Low	-10%	40/60 stock/bond
Very Low	-20%	30/70 stock/bond

Moving beyond capacity to take risk based on human capital, and tolerance to take risk, we look at other factors affecting the ability to take risk. This might be your personal debt levels, whether you already have significant investment capital relative to your age and stage of career, outside sources of cash flow, inheritance, etc.

The biggest factor of all is the need to take risk. If you have more than sufficient capital to meet your life goals based on a conservative return assumption, to the point where just staying ahead of inflation is job #1, then your need for risk is modest. Deviating from that stance toward more risk is a personal preference and not necessarily wrong, as long as you understand the consequences - enduring more volatility and the temptation to abandon your strategy.

In summary, the stock-bond decision drives a large part of your portfolio’s long-term performance. During portfolio design, evaluating different stock-bond combinations can help you visualize the risk-return tradeoff as you consider the range of potential outcomes over time. Once you determine a mix, it can guide more detailed choices of asset classes to hold in the portfolio. And as your appetite for risk shifts over time, you can revisit the mix to estimate how shifting your portfolio mix may impact your wealth accumulation goals in the future.
