Overconfidence gets human beings into big trouble. Fueled by new developments in science and ready access to current and past knowledge and theory, old cautionary rules are thrown out the window at considerable peril. The past century spans two prominent examples of disasters from learnedness-induced overconfidence. The sinking of the Titanic in 1912—the ultimate shipping disaster—was the direct result of the luxury liner, emboldened by its “unsinkable” engineering, plowing through the twin dangers of poor visibility and icebergs at top speed.
Almost 100 years later, an unshakeable faith in the equity risk premium—reinforced by vast data supporting a 10% annual long-term return—caused the $8 trillion U.S. pension supertanker to charge ahead with massive equity allocations into a decade that did not reward equity investors, despite the warning signs of high valuation multiples, 1% dividend yields, and skewed indexes. 1 The sinking of the Titanic was tragic for hundreds of families; the equity market underperformance of the last decade has impacted millions of investors.
The “naughts” were the worst decade ever for U.S. equity investors, even after an astounding rebound in the past 10 months of 2009, during which the S&P 500 Index surged 55%. 2 Yes, worse than the previous two low points: the 1850s and the Depression-riddled 1930s. The result was the “Lost Decade” where the S&P 500 compounded at –1.0% per annum—3.6% below the rate of inflation! The 1850s and 1930s produced +0.5% and –0.1%, respectively. This cumulative loss dragged the total return of the traditional balanced portfolio of 60% U.S. equities (as measured by the S&P 500) and 40% bonds (as measured by the BarCap Aggregate Index) to 2.3%, trailing inflation by 30 bps per annum.
The picture grows far worse when we incorporate typical pension liabilities and 401(k) target returns. Pension liabilities, as measured by the Ryan Liability Index, advanced at an annualized clip of 8.5% per annum. So while the cumulative gain for the 60/40 portfolio was about 25% (less costs), typical pension liabilities advanced over 125%, nearly halving pension funding ratios. The statistics are far worse for 401(k) investors, very few of whom are even vaguely aware of the liability side (their future spending needs).
Most 401(k) educational materials and retirement planning models use too high a return assumption (often 8%) in calculations to estimate how much money to set aside, and tacitly encourage a reliance on growth stocks. Most 401(k) participants did not achieve these overly optimistic returns; in fact, they were unlikely to even achieve the returns for a simple 60/40 passive return because of the higher relative costs of mutual funds, as well as a relentless tendency to chase past winners, reinforced by human resource departments which add the recently-best-performing products to the 401(k) fund roster. The concept of rebalancing—building on the idea that past is not prologue—is rarely followed in the retail community. 3
In this issue we study this abysmal stretch of portfolio performance, both to glean long-term lessons for how we allocate assets and structure equity indexes and to consider whether the “naughts” might lay a foundation for a splendid decade ahead.
It Didn’t Have to Be This Ugly
Plenty of asset classes existed at the end of the spectacular 1990s that, unlike equities, 4 offered attractive risk premiums. Almost all were cast aside as stocks rose to the stratosphere on the tech bubble. Ignoring diversification, investors plowed their money into the U.S. stock market to such an extent that the P/E ratio (using Robert Shiller’s 10-year reported earnings) of the S&P 500 stood at a shocking 44 in December of 1999. Because these other asset classes were ignored, they entered the decade with much more reasonable valuations and, accordingly, produced respectable results over the subsequent 10 years, as illustrated in Table 1. Only U.S. large stocks managed negative returns for this period.
Widening our opportunity set, the decade doesn’t appear so bleak. True, the S&P 500 and EAFE, along with the ubiquitous 60/40 blend, posted negative real returns. However, decent results could be had as three asset classes produced double digit returns—emerging market stocks, emerging market bonds, and REITs. Another four asset classes—emerging local currency, TIPS, long Treasuries, and (surprise, surprise!) fundamentally-weighted global stocks—managed to beat inflation by 5% or more. Equally weighting this collection of 16 asset classes (excluding T-bills and the fundamental indexes, which didn’t exist 10 years ago) produces an annualized return of 6.8%—a 4.2% percentage point premium to inflation. 5 A 6.8% return may have missed many institutions’ return targets, 6 but could hardly be considered a disastrous shortfall.
By embracing a wide assortment of asset classes (in this case, 10 bond-like categories, 4 equity applications, REITs, and commodities), this approach offers diversification and, more importantly, the opportunity to invest in cheap assets and avoid overly concentrating in the most expensive.
The Weighting is the Hardest Part
The failure of the equity-centric balanced portfolio over the last decade was nearly matched by the damaging practice of capitalization weighting equity index portfolios. If you ever thought markets can get a little crazy or a bit disjointed from reality, the venerable index fund, despite all of its wonderful benefits, fails to live up to its considerable potential.
The folly of cap weighting can most vividly be illustrated using the two bookend years of the Lost Decade, 2000 and 2009. In 2000, we saw a bubble and a crash in technology; in 2009, we saw an anti-bubble in deep value and a snap-back.
By early 2000, technology and telecom stocks had risen so much in price, on the promise of the Internet, that they became a combined 45% of market capitalization despite only representing 15% of the economy (as measured by sales, cash flow, book value, and dividends). Greed pushed these stock prices to levels that would be justified only if everything went right. But, many of the companies were competing with one another; they couldn’t all achieve their loftiest goals. Their subsequent collapse dragged down the capitalization weighted indexes far below the average stock’s decline, sowing the seeds for our own Fundamental Index ® research. Cap weighting predictably held peak exposure to tech just before they crashed.
Fast forward to 2009 when indiscriminate selling of deep value stocks, notably financials but also including durables and retail, drove them collectively to a scant 22% of capitalization (down from 31% less than two years before) despite representing over 38% of the economy. Fear had pushed prices (and so portfolio weights) to levels consonant with mass devastation in these sectors—as if the safe haven sectors could have weathered that debacle unscathed. But, every bank failure gives the survivors less competition, increased pricing power, and improved profit potential, exactly as we’ve seen: as the crisis abated, financial shares led this comeback rally. Even with government intervention on an unprecedented scale, we saw Schumpeter’s “creative destruction” at work. Meanwhile, cap weighting held its minimal exposure to these sectors, right before they took off.
