Investors Learn More from Experience Than Textbooks in the 2020s

Abu Dhabi, United Arab Emirates Jul 29, 2026 ALN: There's a difference between understanding markets and understanding yourself in markets. This distinction is crucial for investors, especially in an era characterized by rapid change and unexpected events. While theoretical knowledge about portfolio theory, asset allocation, inflation cycles, and monetary policy is undeniably important, it does not equip investors with the emotional and psychological tools necessary to navigate the tumultuous landscape of financial markets during crises. The real education comes from living through these experiences, from facing uncertainty that cannot be anticipated or fully understood through textbooks alone. It is through these trials that investors discover the true value of their convictions and how they respond when those beliefs are put to the test.

Six and a half years of tests

As we progress through the 2020s, it becomes evident that this decade has presented a unique set of challenges for investors. The first half of the decade has been punctuated by a series of significant market events that have tested the resilience and adaptability of investors. Traditionally, investors might expect to encounter major market shocks every decade, but the years since 2020 have defied this expectation, delivering a near-constant stream of crises that have shaped the investment landscape.

One of the most jarring events occurred in March 2020, when the COVID-19 pandemic led to unprecedented global shutdowns. The swift and severe impact of the pandemic on economies worldwide resulted in a staggering 34 percent drop in global markets over just 32 days. This sharp decline marked the onset of a crisis that many investors were unprepared for, both psychologically and financially. Although the worst of the market turmoil was over within a month, the psychological scars lingered, as many investors grappled with the uncertainty of a world grappling with a pandemic.

Following the initial shock of the pandemic, investors faced another significant challenge from February to October 2022, when geopolitical tensions escalated dramatically with Russia's invasion of Ukraine. This conflict not only exacerbated existing supply chain issues but also triggered inflation rates that reached their highest levels in 40 years. The Federal Reserve's response involved a series of aggressive rate hikes, leading to a bear market that began in June and persisted for several months. The discomfort of this prolonged downturn forced investors to confront their strategies and reassess their risk tolerance in a rapidly changing economic environment.

In September 2022, the financial landscape was further shaken by political missteps in the UK, specifically Liz Truss's mini-budget, which precipitated a crisis in the gilt market. The repercussions were severe, with pension funds on the brink of collapse and the market facing yet another shock. However, history has shown that markets are resilient, and after a period of recovery, investors began to regain their footing.

March 2023 brought yet another wave of concern as the collapse of Silicon Valley Bank, Signature Bank, and Credit Suisse within a matter of weeks reignited fears of a banking crisis reminiscent of 2008. The rapid succession of these failures sent shockwaves through financial markets, prompting widespread speculation about the stability of the banking sector. However, unlike the previous crisis, markets managed to stabilize relatively quickly, illustrating the lessons learned from past experiences and the ability of investors to adapt to new realities.

The geopolitical landscape continued to evolve dramatically in October 2023 with the onset of the Hamas-Israel war. This conflict, marked by significant humanitarian and economic implications, added another layer of complexity to the investment environment. Despite the severity of the situation, markets demonstrated a remarkable capacity to absorb the news, reflecting a growing familiarity with the volatility that has characterized the 2020s.

As we move into 2024, the financial world faced yet another challenge with the unwinding of the yen carry trade, which led to the Nikkei experiencing its worst day since 1987. This event triggered a domino effect, causing global markets to follow suit with sharp declines. However, as has been the pattern throughout this decade, recovery soon followed, showcasing the resilience of markets and the ability of investors to recalibrate their expectations.

In January 2025, the tech sector was rocked by the sudden collapse of Chinese AI start-up DeepSeek, which triggered a global sell-off in technology stocks. The fallout was particularly pronounced for Nvidia, which suffered a staggering loss of $589 billion in a single day, marking the largest single-day loss in market history. Yet, within weeks, the narrative surrounding the tech sector shifted dramatically, demonstrating the unpredictable nature of market sentiment and the importance of maintaining a long-term perspective.

April 2025 saw the introduction of US President Donald Trump's “Liberation Day” tariffs, which led to a swift 12 percent decline in the S&P 500 over just seven days. This event underscored the volatility that can arise from political decisions and their immediate impact on market sentiment. However, as history has shown, markets eventually adjust and price in such shocks, allowing investors to recalibrate their strategies.

The ongoing US-Iran conflict in March 2026, which resulted in the closure of the Strait of Hormuz, added yet another layer of uncertainty to the investment landscape. Markets experienced a decline of around 10 percent from recent highs, and the conflict's continuation into mid-July kept investors on edge. This situation serves as a reminder that the global economic environment is intricately linked to geopolitical events and that investors must remain vigilant in their assessments of risk.

In total, the past six years have witnessed nine significant events that have shaped the investment landscape, not to mention the smaller shocks and corrections that have filled the gaps between these major occurrences. Each event has provided valuable lessons for investors, highlighting the importance of emotional resilience, adaptability, and a deep understanding of both market dynamics and personal psychology. As we continue to navigate the complexities of the 2020s, the experiences gained from these trials will undoubtedly influence investment strategies for years to come.

Ultimately, the journey of an investor is not solely about financial returns; it is also about personal growth and understanding one's own reactions to market fluctuations. The lessons learned from the crises of the 2020s will shape the next generation of investors, equipping them with the tools necessary to navigate future challenges with greater confidence and insight.
