Recently, I’ve come across a thought-provoking question: when there are sudden, unpredictable, and severe market fluctuations, how should we respond?

This is what’s known as a black swan event—an extremely rare but far-reaching economic phenomenon. Look at what has happened in recent years: the 2008 housing market crash that triggered a global financial crisis, the COVID-19 pandemic that caused stock markets to plunge by more than 20% within a month, the Russia-Ukraine war, Europe’s inflation hitting a 40-year high, and then the chain of failures among cryptocurrency exchanges. Each time, it disrupted the market’s rhythm and dealt a blow to investor confidence.

But here’s an interesting finding: according to research data, if you buy at a timing that is halfway into the decline after a black swan event occurs, the market averages a rise of 20.4% after the event ends within 6 months, with an excess return of 13.3%. In other words, crisis often breeds opportunity.

Economic recession is the most destructive type of black swan event. The last time the global economy went into a sustained downturn was in 2008, when the S&P 500 index fell by more than 56% from its peak, causing investors’ wealth to vanish in an instant. Today, global growth is slowing and recession risks loom—driven by a combination of factors such as adjustments in fiscal policy, heightened geopolitical tensions, rising unemployment, and more.

Fluctuations in interest rates are a key factor behind black swan events in the stock market. Central bank rate cuts often imply economic difficulties and can trigger continued market sell-offs. Investors need to understand this logic and manage risk with appropriate tools—such as allocating gold to hedge, or using derivatives like options to protect stock investments.

When it comes to cryptocurrencies, this emerging asset class is inherently full of uncertainty. Bitcoin once surged to $68,000 due to purchases by publicly listed companies such as Tesla and MicroStrategy, but when a bear market arrived, it also fell significantly. Recently, Bitcoin broke through $100,000, and Bank of America strategists warned that bubble risks are increasing. The collapse of FTX is a vivid example, illustrating the impact that black swan events may have in the crypto space. However, in the long run, these crises may also drive innovation in blockchain technology.

Dollar fluctuations should not be overlooked either. A strengthening U.S. dollar can reduce overseas income for U.S. multinational corporations. Microsoft, for example, once lost nearly $600 million in profit due to a strong dollar. The dollar’s movement is influenced by Federal Reserve policy, economic growth, international trade, and geopolitical factors, with emerging markets hit especially hard.

So how should we respond to black swan events?

First, diversify your investments. Don’t put all your eggs in one basket—allocate stocks, bonds, precious metals, and real estate in a balanced way. Gold is especially worth paying attention to—since the 2000s, its average annual return has been between 8% and 10%, far outperforming the bond market, and it is a classic tool for hedging against inflation.

Second, keep cash reserves. When a black swan event triggers a market plunge, having cash on hand allows you to buy high-quality assets at attractive prices and avoid being forced to sell.

Most importantly, maintain a long-term perspective. The short-term impact of black swan events is often intense, but the market will eventually rebound and recover. More advanced investors can also consider tools such as contracts for difference and futures to hedge risks.

Put simply, black swan events are both a crisis and an opportunity. The key is to be prepared so that when it arrives, you won’t be caught off guard.
