Recognizing, Avoiding, and Controlling Risk
Three distinct skills, easy to conflate — and risk recognition is hardest exactly when calm markets make it feel least necessary.
Marks separates risk management into three distinct skills that are easy to conflate but genuinely different: risk recognition — being aware that meaningful risk exists in a given situation, especially when everything currently looks calm; risk avoidance — choosing not to take on risks that aren't adequately compensated; and risk control — limiting the damage from risks that are taken on anyway, through sizing and diversification.
He's specific that risk recognition is hardest exactly when it matters most — during extended calm, low-volatility periods, often late in a bull market per the pendulum metaphor covered earlier, investors as a group tend to systematically underestimate how much risk is actually present, precisely because recent experience hasn't punished that risk-taking yet.
Risk control, the third skill, acknowledges that risk avoidance alone isn't always possible or even desirable — some risk-taking is necessary to earn a return at all — which is why sizing positions appropriately and diversifying across genuinely independent risks is treated as a distinct, necessary skill rather than a fallback for investors who failed at avoidance.
| Skill | What it actually involves |
|---|---|
| Recognition | Being aware meaningful risk exists, especially when things currently look calm |
| Avoidance | Choosing not to take on risks that aren't adequately compensated |
| Control | Limiting damage from risks taken on anyway — sizing, diversification |
During an extended stretch of low volatility and rising prices, the recent, lived experience of taking on more risk has simply been rewarded, repeatedly — which can make risk feel, to investors as a group, like it's genuinely diminished, even when the actual underlying risk may in fact be building rather than fading.
A stretched valuation, or excessive leverage quietly building up in the system, can coexist with historically low measured volatility for a long stretch — recognizing the risk in exactly this kind of environment, when recent evidence seems to argue against it, is the hardest and most valuable version of this skill.
Even a genuinely well-analyzed, high-conviction position can turn out badly for reasons no analysis could have anticipated — which is why appropriate position sizing and real diversification across independent risks remain necessary even when an investor is highly confident in a specific view, rather than being treated as an admission of doubt about that view.
- Risk recognition, avoidance, and control are three distinct skills, easily conflated but genuinely different in practice.
- Risk recognition is hardest during calm, low-volatility periods, precisely because recent experience seems to argue against caution.
- Avoidance alone isn't always possible or desirable, since earning any return requires taking on some risk.
- Position sizing and real diversification remain necessary even for high-conviction bets — they're not an admission of doubt, but a distinct, separate discipline.
