Margin of Safety Ch. 5: Absolute vs. Relative Performance

"Relative-performance investors buy securities they know to be overvalued rather than fall behind their peers. That is not investing; it is career preservation." — Seth Klarman

Investment Context

Klarman returns repeatedly to a distinction that explains many seemingly irrational institutional decisions:

  • Absolute return: The goal is not losing money and earning a reasonable return, independent of anyone else.
  • Relative return: The goal is beating a benchmark or peer group, so losing alongside them counts as success.

Under relative return, "down 18% when the benchmark fell 22%" is a victory. To someone living off that capital, this is plainly absurd — yet the entire asset management industry operates on that standard.

The Wall Street Translation

1. How Relative Return Distorts Decisions

| Situation | Absolute-return investor | Relative-return investor | |---|---|---| | Market clearly overvalued | Holds cash and waits | Must stay fully invested or lag | | A sector becomes a bubble | Avoids it | Forced to participate — it is in the benchmark | | No good opportunities | Does nothing | Doing nothing is seen as dereliction |

The key: relative-return constraints force managers to take maximum risk at the most dangerous moments. This is not an ability problem but an incentive problem.

2. Cash as a Position

One of Klarman's best-known practices is holding large cash balances when nothing is cheap enough — at times 40%–50% of the portfolio.

For a relative-return manager this is unthinkable: cash drags on relative performance and clients redeem. For Klarman it is simply an honest admission that nothing currently merits purchase.

Doing nothing is an active decision, not an absence of skill.

3. Individuals Hold a Genuine Advantage Here

This is a concrete instance of the structural edge in Market Wizards Chapter 3 on this site: you never have to explain a quarter to anyone.

You can hold cash for two years without justification. You can avoid a sector everyone is discussing. You can accept a flat year while peers profit. Almost no institutional investor can do any of these three things.

4. Yet the Advantage Is Usually Surrendered Voluntarily

Most individuals place themselves under relative-return pressure anyway — comparing returns with friends, tracking whether they "lagged the market," regretting a stock they did not own.

These behaviors convert a structural advantage into a psychological burden, with the result of chasing risk exactly when they should not.

5. How Absolute-Return Thinking Changes the Withdrawal Phase

For those already retired, the irrelevance of relative performance is sharper still: your bills do not shrink because the index also fell.

The planning implication is concrete: a retirement portfolio's success criterion should be sustaining spending through the worst thirty-year sequence, not maximizing terminal value in the average case.

This points to the same conclusion as ergodicity in Antifragile Chapter 6 and sequence-of-returns risk in Option Volatility and Pricing Chapter 4 — the measure must be your own survival, not comparison with others.

Actionable Trading Rules

  1. Measure yourself in absolute terms: Your objective is the real return your retirement requires, not beating an index.
  2. Accept that doing nothing is a valid action: If nothing meets your criteria, holding cash is a legitimate decision rather than a failure.
  3. Stop comparing: Other people's returns are irrelevant to your financial goals, and comparison systematically inflates your risk appetite.
