Reinvesting When Terrified

GMO is a Boston asset manager co-founded in 1977 by Jeremy Grantham with Richard Mayo and Eyk Van Otterloo, known for valuation-driven dynamic asset allocation built on long-horizon mean reversion. Grantham is famous for calling historic bubbles, warning publicly ahead of both the 2000 dot-com crash and the 2008 financial crisis. Flagship publications include the GMO Quarterly Letter (now written by Asset Allocation co-heads Ben Inker and John Pease), Grantham's Viewpoints essays and the 7-Year Asset Class Forecast.

In plain words

This piece is about why investors freeze up when markets crash, holding cash and missing the rebound. The author argues you shouldn't try to buy at the exact bottom—that just makes you more paralyzed. Instead, make a simple plan in advance and stick to it, even if it feels scary. For example, in October 2008, GMO bought stocks aggressively on a preset schedule, knowing they might be early. The lesson: don't wait for clear skies; by then, prices have already bounced.

Theme and Background

This chapter discusses how investors can overcome "terminal paralysis" and execute a reinvestment plan when market panic reaches its peak. The report argues that as the crisis intensifies, investors holding cash will find it increasingly difficult to part with it, thereby missing most of the market recovery gains.

Core Thesis

The author's core investment argument is: Investors must formulate a clear reinvestment battle plan and execute it strictly; otherwise, inertia will cause them to miss opportunities. Counterintuitive judgments include:

  • Pursuing the optimal solution (e.g., catching the exact bottom) is a trap that exacerbates paralysis; a simple plan is far better than inaction.
  • The market does not reverse when the light appears at the end of the tunnel, but rather when "everything looks dark, but slightly less dark than the day before."
  • Value investors always sell too early in bubbles and buy too early in crashes, but in return, they earn excess returns and reduce average risk over the full cycle.

Key Arguments and Data

  • GMO's Actual Actions: In October 2008, GMO executed a large-scale reinvestment, adjusting its position to halfway between "neutral" and "minimum equity allocation," and established a schedule for increasing positions as the market declined further.
  • Valuation Judgments:
  • The fair value of the S&P 500 is 900 points, 30% above the then-current price.
  • Global equities are cheaper than U.S. equities.
  • The 7-year expected real return (inflation-adjusted) is +10% to +13%, compared to negative returns across all categories a year earlier.
  • Historical Comparisons:
  • At the 1974 low, the 7-year expected return reached +15%.
  • There is still a 50/50 probability that the S&P 500 could fall below 600 points.
  • Historical Rebound Cases:
  • In June 1933, the S&P rebounded 105% in six months (at a time when not all banks had failed and unemployment had not yet peaked).
  • In 1974, the UK stock market rebounded 148% in five months.
Indicator Current (March 2009) One Year Ago 1974 Low
S&P 500 Fair Value 900 points (30% above market price) - -
7-Year Expected Real Return (Equities) +10% to +13% All negative +15%
Probability of S&P 500 Falling to 600 50/50 - -

Companies/Assets Involved

  • GMO: The author's institution, which has already executed a reinvestment plan. The author emphasizes that GMO's approach involves "a few large moves" rather than "many small steps."
  • S&P 500: Used as a proxy for the U.S. stock market, with a fair value estimate of 900 points.
  • Global Equities: Considered cheaper than U.S. equities, with higher expected returns.
  • UK Stock Market: A 1974 rebound case (up 148% in five months), used to illustrate the intensity of market reversals.

Investment Implications

  • Act Immediately: Investors must secure agreement from their committee or themselves on a reinvestment plan before "rigidity" sets in (i.e., before market sentiment freezes completely).
  • Execute in Large Batches: Do not attempt to ease psychological pressure by adding positions in small increments. Instead, recommend a few large-scale actions, as each action requires overcoming significant psychological hurdles.
  • Accept Imperfection: Do not aim to catch the exact bottom. Value investors inevitably buy too early, but this is the price of earning long-term excess returns.
  • Quantify Risk: Simulate the costs and regrets of two errors—"investing too early" versus "investing too little"—and formulate a plan accordingly. If quantification is not possible, a simple plan is still better than no plan.
