The Elusive Role of Luck in Investment Management

The concept of luck often remains elusive and under-discussed within the realm of professional investment management. Despite our efforts to ground our practices in scientific rigor—citing studies about asset allocation influencing over 90% of portfolio returns and utilizing efficient frontier charts—clients often leave meetings hoping for a touch of luck to bolster their investments.

This dichotomy exists because, as advisors, we’ve been steeped in financial curricula that emphasize scientific precision over the unpredictable nature of markets. Yet, deep down, many of us recognize luck’s significant role in investment outcomes but hesitate to discuss it openly. Acknowledging luck can seem incongruent with the confident, calculated forecasts we’re trained to provide.

The Impact of Luck on Investment Strategies

Let’s dissect how luck can dramatically influence investment outcomes by exploring its key components:

  1. Market Timing and Secular Trends: The timing of an individual’s entry into the market can be a substantial factor of luck. For instance, beginning investments at the onset of a secular bull market can result in significantly positive early returns, thereby enhancing the long-term performance of a retirement portfolio.
  2. Inflation: Experiencing low inflation during retirement constitutes another aspect of luck. A benign inflation environment allows retirees to adjust their withdrawals minimally, thereby preserving purchasing power and extending the longevity of their portfolio.
  3. Reverse Dollar Cost Averaging (RDCA): Cyclical market trends can lead to RDCA, which accelerates portfolio depletion. This is especially impactful during periods of market downturns when withdrawals may disproportionately erode the capital base.

Illustrating Luck with a Case Study

Consider Bob, who is retiring this year at 65 with a $1 million portfolio split between fixed income and equities. His retirement timing could dramatically alter his financial longevity. For example, had Bob retired during the early stages of a secular bull market (such as the early 1920s, 1950s, or late 1970s), his portfolio could sustain his withdrawals for 30 years or more. Conversely, retiring during less favourable periods could reduce his portfolio’s life expectancy to around 17 years.

Conclusion: Embracing the Unpredictability

While we can’t control luck, recognizing and quantifying its influence allows us to strategize more effectively. By acknowledging that luck plays a considerable role alongside strategic planning, advisors and clients can liberate themselves from the confines of traditional investment paradigms and explore broader, more resilient financial strategies. Thus, rather than ignoring luck, embracing its reality enables us to seek out diversified income streams and solutions that provide financial security over the long haul. This approach not only aligns more closely with the unpredictable nature of financial markets but also sets a more realistic framework for managing client expectations and portfolio performance.
