IDTT: It’s Different This Time

By Rob Arnott

APRIL 2009 Read Time: 10 min

If there was ever a slogan that scares the heck out of seasoned investors, this is it. It is unarguably true—always—because, as Mark Twain observed, “history may not repeat, but it sure rhymes.” It is just as arguably untrue in that things are rarely as “different” as the IDTT crowd wants us to believe. It has been uttered to support bubbles and investor euphoria, and to justify crashes and deeply depressed values, in the face of vast evidence to the contrary.

How many times has reversion to the mean destroyed the wildly optimistic projections accompanying those four simple words? Upon entering the phrase into Google, the first link that pops up is to for "Dow, 30,000 by 2008—Why It's Different This Time” by Robert Zuccaro.1 In the midst of our current market environment, this treatise of unbridled optimism seems like something from a long buried time capsule, an archeological relic of a bygone era, not a work published seven years ago still available for purchase.

A lot can happen in seven years (although perhaps not Dow 30,000.) Perhaps most remarkable is how often, and in what contexts, the phrase “It’s Different This Time” is used today. This time, it’s used to justify extreme pessimism, the death of mean reversion, the folly of rebalancing, and the failure of diversification. Indeed, the second Google link takes you to an LA Times article from March 2008 detailing the parallels between the Great Depression and the then still blossoming financial crisis.2

The same four words plugged into a search engine spit out seemingly opposite headlines—seven years of unprecedented stock market gains and an indefinite period of economic disaster. To a contrarian, the irony could not be any thicker. Pessimistic at the turn of the century, we soundly rejected the IDTT arguments of the day. Today, we find ourselves in an unaccustomed position: we’re optimists in some markets, believing that now is an excellent time to take the long view and allow heightened risk premiums to accrue to investors’ benefit.

Finding the “Walking Wounded” in the Markets’ Carnage
The hoped-for rebound, following the “Take-No-Prisoners” market crash late last year, failed to materialize in the first quarter or 2009. Markets continued their slide in the first quarter of 2009, expanding the losses for investors in virtually all asset classes. Indeed, during February, 15 of the 16 major markets that we track in our Global TAA work fell; the equally weighted portfolio fell nearly 5%. How often had that happened before, going back as far as we have the relevant data? Never … until late 2008. This unprecedented event—15 out of 16 asset classes falling with a –4% average in a single month—happened for the first time ever in September 2008. And repeated in October and again in February—thrice in a six month span. If we exclude last fall, February 2009 would be comparable in breadth (number of positive assets classes) to August 1990 and severity (equally weighted decline) to September 2001; two months that preceded war and major financial uncertainty. Yet, February gets comparatively little attention because it pales next to the carnage of last September–October.

During the 21-month period of this financial crisis (measured July 2007 through March 2009), the equally weighted portfolio of 16 asset classes3 was not spared. With its expanded toolkit, broad diversification, and liberal use of ostensibly uncorrelated alternative markets, this naïve 16-asset-class portfolio added 460 basis points of relative value versus the 60/40 mix (–21.4% versus –26.0%). Clearly, this diversified portfolio failed to keep investors in the black, and we are cognizant that many investors are growing increasingly frustrated that diversification hasn’t provided stronger protection in this crisis. Indeed, it is remarkable in a historical context how relative value between asset classes—a key driver of correlation and diversification—has been thrown out the window.

Consider the performance of investment-grade corporate bonds versus stocks in Figure 1 over two distinct time periods. The first covers September 1929 through June 1932, a period in which the S&P 500 Index cumulatively declined by 84%. We will label this period “The Great Depression.” The second period, which we label “The Great Recession,” covers the most recent drawdown of the S&P 500 (–47%) from November 2007 through March 2009.4

Remarkably, corporate bonds provided measurably better diversification during the first 17 months of the Great Depression versus the first 17 months of our current crisis—returning +11% then versus –4% now. If such data existed, we believe we would find similar results on the other asset classes in our broader toolkit (REITs, commodities, emerging markets, etc.)—i.e., more benefit from diversification in the Great Depression from assets that should structurally provide better down market protection than in the Great Recession of 2008–09.

Does that mean it is different this time? Certainly, a more intertwined global financial market in the midst of a massive deleveraging cycle may mean a period of higher correlations, rising risk premiums and a de-linking from fundamental drivers of returns. So in the shorter term, yes, it is different this time. However, a true long-term (i.e., 10 years or more)5 investor will not be dismayed and fall into the IDTT camp. Risk premiums will, and in many cases have, reached a point where investors are rewarded to take risk. After all, taking well compensated risks is what ultimately leads to significant long-term wealth creation. As Benjamin Graham once noted, “The essence of investment management is the management of risks, not the management of returns.”

Is It Different This Time?
Apart from the truism that it’s always somewhat different, we don’t think so. In time, valuations will adjust to the point that investors will be well compensated for taking risk. In many markets, we think that’s already the case. When that happens, investors will gravitate to those markets and in so doing will drive asset class correlations to a level validating diversification. An examination of the TIPS market illustrates this point.

Our research indicates that long-term U.S. government bonds have provided real (after inflation) returns of 1.9% over the past 100 years. Last November, real yields on the 20-year TIPS peaked at 3.4%. Real yields hadn’t been so lofty since mid-2000 when TIPS were still a relatively new and little understood asset class (and many investors preferred the 20–30% annual gains that they expected from their NASDAQ holdings!).

Historically, the biggest risk to the bond investor was inflation, but TIPS adjust for rising prices and eliminate this uncertainty. If we suppose that “insurance” is worth 0.3% per year, we can arrive at a fair real yield for a long TIPS investor of 1.6%, half of what they were yielding last November. As deleveraging slowed over the past four months, relative value investors swooped in on TIPS leading real yields to fall most of the way back to our 1.6% fair yield. (The 20-year TIPS finished the quarter with a yield of 2.0%) Critically to the asset allocator, the performance of TIPS moved to a more historical and logical relationship to stocks as seen in Figure 2, which displays monthly returns over the past 6 months.

This return to normalcy will, in our opinion, progressively proceed down the roster of severely dislocated asset classes. And what a roster! Figure 3 outlines various valuation measures for some key mainstream and alternative asset classes.

Most of these assets’ current valuations are in the cheapest quintile of their historic profile. Fixed-income credit categories such as convertibles, investment-grade corporate, high-yield, and emerging market bonds are showing spreads over Treasuries rarely, if ever, witnessed before. Breakeven rates between TIPS and nominal Treasuries are still very low, even after the previously described dive in TIPS yields.6 REIT yields versus stock yields are in the cheapest quintile since 1980. Even dividend yields on the S&P 500 are starting to get to levels where stocks can (finally) be considered a reasonable risk/reward opportunity.

Does cheapness equate to value? Not always, of course. Will some of these asset classes be repriced to levels not witnessed over the past 25–50 years? Probably, and in those cases it may be different this time. But what is not different is that risk premiums (today’s for some asset classes and tomorrow’s for others) will entice new investors once they come to grips with their recent results. These value-oriented entrants will cause differentiation among asset classes and, correspondingly, a reduction in correlations.

This adjustment will not be a smooth process and it will likely take some time, undoubtedly making some queasy along the way. But that’s good news for all of us in the asset allocation business with strong stomachs, from the strategically oriented institutions to the tactically inclined managers like Research Affiliates. We know that what is comfortable is rarely profitable… and the most profitable opportunities are often the most uncomfortable investments to make. For this reason, contrarians form a disproportionate share of the world’s all time greatest investors. Over the past 25 ebullient years, many contrarians have been labeled nothing more than doomsayers and reactionaries. How refreshing it is to be on the “glass is half full” side of the room! But yet again, we see we have very little company—the contrarian’s loneliness is never different this time.

3. The 16 asset classes include mainstream stocks and bonds, alternative bonds, and real return assets. The equally weighted portfolio is comprised of the following indexes, rebalanced monthly: Merrill Lynch (ML) U.S. Corporate & Government 1–3 Year; Lehman Brothers (LB) U.S. Aggregate Bond TR; LB U.S. Treasury Long TR; LB U.S. Long Credit TR; LB U.S. Corporate High Yield TR; Credit Suisse Leveraged Loan; JPMorgan (JPM) EMBI + Composite TR; JPM ELMI + Composite; ML Convertible Bonds All Qualities; LB Global Infl ation Linked U.S. TIPS TR; FTSE NAREIT All REITs TR; DJ AIG Commodity TR; S&P 500 TR; MSCI Emerging Markets TR; MSCI EAFE TR; Russell 2000 TR.
4. This recent period doesn’t have as many months. Hence, the time series comes up short for this recent stretch. Alas, we don’t have the clairvoyance to complete the graph!
5. It should be noted that very few among us isn’t a 10-plus year investor. Even those reaching retirement age will, according to the actuarial tables, require investments to provide income for 15–20 years.
6. The breakeven inflation rate is calculated as the difference between the nominal Treasury and TIPS of the same maturity. A low break even rate implies that only modest inflation will allow the TIPS to outperform the nominal Treasury.
