Defense First: Why risk management is more important than returns

It is March 2022. Your portfolio fell from €5m to €3.5m – a 30% loss in 6 months. They panic and sell everything to avoid further losses. Then the market recovers and 2 years later you would have €6.5 million. This is the worst mistake investors make: they care about maximum returns, not minimal risks. Yale has a system: It doesn't optimize for maximum returns, but rather for "acceptable returns with controlled drawdown." This article will show you why Defense-First.

The Mathematics of Drawdown: Why Protection is Critical

Here's the brutal math:A 50% loss needs 100% gain to recover.

If you have €5 million and lose 50% (losing €2.5 million), you have €2.5 million left. To go back to €5m you need 100% profit on the remaining €2.5m. Not 50%.

This illustrates why risk management is critical:

• 10% loss → 11% gain to recover
• 20% loss → 25% gain for recovery
• 30% loss → 43% gain to recover
• 40% loss → 67% gain to recover
• 50% loss → 100% gain for recovery

The implication:Protection against large losses is more important than maximum profits.

Yale's drawdown control system

Yale defines “acceptable risks” as:Maximum expected drawdown of -20% in 95% of years.

This means: Yale builds its portfolio so that it only loses more than 20% in extreme years (like 2008, 2022). In normal years the drawdown is <10%.

How does this work? Through diversification:

• 20% real assets (real estate, timber) – only lose -5% to -10% in bear markets
• 30% alternative investments (private equity, hedge funds) – because they are illiquid, they lose less (a fund that is not traded daily loses less than stocks)
• 40% Equities (with international mix) – to get upside
• 10% bonds – stability

The idea: If stocks lose 30%, alternatives only lose -5%, real estate -5%, bonds +2%. Total portfolio loss: ~-8%.

Practical Risk Management: Volatility Targeting

Volatility targeting is the simplest practical method:

Define your acceptable volatility.
»I can live with 8% annualized critical volatility.«

Rebalance dynamically.
If your volatility rises to 12% (e.g. because stocks become volatile), you deleverage: sell 20% equities, buy bonds.

Use hedges for tail risks.
3-5% of the portfolio in put options (insurance) in the event of a -20% plus market.

Example: - Your portfolio has 10% volatility - You define 8% as your goal - Markets become volatile, volatility increases to 12% - You sell 25% equities, buy bonds - New volatility: 8.5% (close to target)

The Psychological Component: Understanding Drawdown Tolerance

The critical element ispsychological drawdown tolerance: How much can you take emotionally?

If you have a portfolio with -30% drawdown potential but can only emotionally tolerate -15%, you will panic sell in the bear year. That's the mistake.

Yale's approach:Build a portfolio with drawdowns you can handle emotionally.

• If you can't stand -20%, build a portfolio with -10% to -15% maximum.
• If you can tolerate -30%, build for -25% maximum.

Then, during a bear year, it is psychologically easier to hold. You “expected” a -15% drawdown and got -12%. They are happy.

If you didn't anticipate the drawdown and get -25%, you are selling in panic.
