Investors again underestimate market risks
A financial product that once seemed to guarantee easy profits now stands as a cautionary tale. In March 2007, an investment bank introduced a Constant Proportion Debt Obligation (CPDO), a structured note rated AAA at launch. By November of that year, it had failed. The downfall did not occur because investors overlooked risk, but because they had spent years treating it as an unlikely possibility. That same mindset remains prevalent today.
How Markets Narrow Their Own View of Risk
Two decades later, the conditions are eerily similar. Liquidity remains plentiful, credit spreads are tight, and advanced models continue to suggest that extreme market shifts are improbable. Investors, driven by the search for returns in a low-yield environment, are repeating past behavior by assuming stability will persist. The issue is not that they ignore risk. It lies in the fact that prolonged stability has narrowed the range of plausible risks within their models. Severe spread widening is assigned near-zero probability—not because it is impossible, but because considering it is inconvenient.
The CPDO’s design depended on stable spreads to function. Its success rested on assumptions that effectively excluded the very scenario that later destroyed it. By November 2007, the product had collapsed, leaving investors with losses that fundamentally altered the industry.
This pattern has extended across asset classes. High-yield bond investors abandoned protections meant to shield them from defaults, only to face losses that exposed the value of those safeguards. The yen carry trade thrived until excessive leverage and crowded positions turned a controlled strategy into a violent unwinding. Today, leveraged ETFs, single-stock ETFs, and leveraged single-stock ETFs operate under the same principles: using innovation and leverage to generate returns where underlying assets no longer suffice.
The Hidden Cost of Confidence
The financial system today is stronger than it was in 2008. Banks hold more capital, balance sheets are cleaner, and many vulnerabilities from the Global Financial Crisis have been addressed. Yet investors often focus on the risks they have mitigated while overlooking others. Risk does not disappear—it simply shifts. When a leveraged investment falters, investors do not sell the failing asset. Instead, they sell whatever is liquid, dragging unrelated assets into distress. Contagion spreads not through direct connections but through the behavior of those holding the risk.
Why the Same Mistakes Keep Happening
The core problem lies in how investors evaluate opportunities. Rather than asking, “What is the likely return on this investment, and is it sufficient compensation for the risks?” many inverted the problem: “This investment does not return enough.” Returns are visible and compelling, while risks are often hidden, nonlinear, and only surface under stress. An internal blog from 2025 noted that investors may correctly identify risks; but acting on that understanding can be commercially damaging. As a result, overvalued markets persist longer than they should, until a sudden repricing forces a correction.
