Every investor loves to talk about “resilience.” CEOs put it in their shareholder letters. Risk managers print it on glossy slide decks. Politicians throw it into speeches. But resilience is a funny thing — it only shows up when something goes wrong. And markets have a nasty habit of scheduling stress tests without asking your permission.
Think back to March 2020. Liquidity evaporated like someone had yanked the plug out of the global financial system. Safe havens weren’t safe — even Treasuries, the backbone of the entire global system, saw their yields spike as investors scrambled for cash. That wasn’t a market moving rationally; that was a system in free fall. And here’s the kicker: nobody had “pandemic” at the top of their scenario planning slides. Yet, the stress test arrived.
So, what do you do with this? How do you prepare for the un-preparable?
1. The Myth of Perfect Hedging
Many portfolios hide what I like to call Shadow Portfolios — unseen exposures that only reveal themselves under duress. You think you’re diversified, but in reality, everything’s leaning on the same correlation domino. When those dominos topple, you don’t just get hit — you get blindsided.
Stop thinking of hedging as fireproofing. It’s more like fire doors in a building: you don’t eliminate risk, you slow the spread. If you’re betting that your hedge will save you in every crisis, you’re setting yourself up for a rude awakening.

2. Stress Testing as an Act of Imagination
Here’s the irony: stress testing isn’t about predicting the next crisis. It’s about cultivating imagination.
What happens if bonds and stocks crash together?
What happens if your counterparty fails while your model is mid-trade?
What happens if liquidity disappears in the one asset you thought was tradable?
These aren’t paranoid questions. They’re the mental gymnastics of a resilient investor. In fact, the Bank for International Settlements (BIS) has been urging funds for years to conduct “reverse stress tests” — not just “what if” scenarios, but “how would I break my own portfolio” drills. BIS on reverse stress testing.
It’s the financial equivalent of martial arts sparring: you don’t train for the exact punch, you train to be adaptable when the punch comes from the angle you least expect.
3. Building Anti-Fragility Instead of Fragility
Nassim Nicholas Taleb popularized the word antifragile — systems that don’t just survive stress but grow stronger from it. Portfolios can be designed this way too. Not by chasing perfection, but by sprinkling in small, asymmetric bets. Things that don’t cost much when they fail, but explode positively if the unexpected happens.
For example:
- A sliver of gold exposure during inflation panic.
- A tail-risk hedge (think deep out-of-the-money puts) during euphoric bull runs.
- Even a few Moonstakes in contrarian tech when everyone else is terrified.
Each is small enough not to hurt when wrong, but powerful when the improbable slaps the world awake.
4. The Human Factor
Don’t forget: the worst stress tests aren’t in the spreadsheets. They’re in the mirror.
- Will you panic-sell into a crash?
- Will you chase liquidity mirages when spreads widen?
- Will you freeze when decisive action is needed?
Behavioral finance is littered with reminders that humans fail under pressure. But the discipline to rehearse your response in calm times is the single biggest predictor of how you’ll perform under duress. Write it down. Make a checklist. Pilots don’t rely on gut feelings when engines catch fire. Neither should you.
5. The Takeaway
You don’t get to pick the timing of your stress test. Markets will do it for you. But you do get to pick how you prepare:
- Spot your hidden exposures.
- Run imaginative drills.
- Add small asymmetric edges.
- Train your own reflexes.
Because the market’s next unscheduled exam won’t ask politely. And when it comes, you don’t want to be the investor muttering expletives while flipping through a half-written playbook.
👉 Your turn: Have you run a stress test on your portfolio in the past year? Not the Excel version — the mental one, where you imagine the unthinkable? If not, maybe it’s time.
