When financial markets enter an upswing, interest in investing grows. Particularly when global equities rally as they have recently, regret over uninvested assets intensifies. Paradoxically, however, retirement pensions can face greater risks during such "good times."
The asset structure of Korea's retirement pensions helps explain why. According to the Financial Supervisory Service's Integrated Pension Portal, as of last year, a substantial portion of defined contribution (DC) and individual retirement pension (IRP) reserves remained in principal-guaranteed products. Despite being long-term assets, they are largely managed based on short-term interest rate conditions. As markets rise, this structure immediately translates into a return gap — in other words, opportunity cost.
The real problem comes afterward. The perception of having missed opportunities in a bull market tends to lead to belated investment. Individual investor fund flows show a recurring "return-chasing" pattern: inflows increase after market rallies, while outflows occur during downturns. Investment timing is effectively shaped by chasing the market.
This phenomenon is also evident in performance gaps. U.S. investment research firm Morningstar analyzed the difference between fund returns and actual investor returns in its "Mind the Gap" report. According to the 2024 report, investors over the past 10 years showed an annual performance gap of about 1 percentage point, missing out on roughly 15% in cumulative returns. This means that timing, not just product selection, significantly influences performance.
Behavioral patterns tell a similar story. Global asset manager Vanguard analyzed that investors tend to increase equity exposure in bull markets and reduce it in bear markets — the classic "buy high, sell low." While such choices may seem rational at the time, they undermine asset allocation principles over the long term and cause investors to miss return opportunities during recovery phases.
The same pattern repeats in retirement pensions. When assets that had been sitting in principal-guaranteed products move belatedly into risk assets during a bull market, the likelihood of entering at a peak increases. When volatility then expands, the money shifts back into safe assets, and long-term returns fall short of expectations in a repeating cycle.
Ultimately, the risk in retirement pensions arises not from market declines themselves, but from investment behaviors that repeat according to market conditions. Bull markets are the most powerful environment triggering such behavior. Regret over periods of non-investment leads to belated decisions, which in turn translate into losses during the next downturn.
Retirement pensions are not assets that generate returns through short-term judgment. Results are determined through the process of maintaining a consistent asset allocation and investing over the long term. What matters is not the ability to time the market, but the discipline to adhere to a predetermined asset allocation principle.
In the end, the moment to be most cautious is not when markets look bad, but when everything appears to be going well. Retirement assets must be managed by structure, not emotion, and preserving that structure is the standard that determines long-term performance.
