Growth Stock Investing: Play the Long Game

LONDON, February 7, 2023 — A former fund manager who oversaw a portfolio that grew seventeenfold over two decades is now publicly dissecting the flaws he sees within the investment world. The shift comes as he prepares to step down from direct management, but continues advising on £5.3 billion in assets.

The seasoned investor is challenging conventional wisdom, arguing that the industry’s obsession with minimizing volatility misses the true risks and opportunities for substantial returns.

Key Takeaways

  • Volatility isn’t the enemy; permanent capital loss is.
  • A tiny fraction of companies drive the majority of market wealth.
  • Short-term thinking creates inefficiencies for patient investors.
  • Imagination is crucial for evaluating companies with exponential growth.
  • Technological progress, particularly in artificial intelligence, is a key driver of future returns.

The core of his critique centers on modern portfolio theory, which he believes wrongly equates volatility with risk. He contends that the real danger lies in “permanent capital loss,” even as established companies experience significant, temporary stock price declines.

What’s the biggest mistake investors make? Failing to recognize that extreme market events—and returns—happen far more often than traditional financial models predict. He points to the research of Hendrik Bessembinder, which shows that over half of the wealth created by U.S. stocks since 1990 has come from less than 1% of publicly traded companies.

The Allure of the ‘1%’

Missing out on these “Super Winners” is a far greater risk than losing money on numerous smaller investments, he argues. The investor emphasizes that consistently small losses are statistically insignificant compared to the potential gains from identifying and holding onto truly transformative companies.

He also takes aim at the industry’s short-term focus. The pressure to deliver quarterly and annual results, he believes, creates market inefficiencies that benefit long-term investors willing to look beyond the immediate horizon. A time frame of five to ten years, he suggests, is the minimum for meaningful analysis.

Beyond the Balance Sheet

Traditional financial analysis, he asserts, is too focused on current data. To truly understand companies poised for exponential growth, investors need “imagination” – the ability to envision future possibilities that far exceed even the most optimistic current projections.

The investor highlights the importance of recognizing areas where costs are falling exponentially due to technological advancements, citing Moore’s Law in semiconductors and Wright’s Law in batteries and genetics. He believes we are now entering a “Paradigm of Intelligence,” with artificial intelligence as the primary engine of progress.

“Brokers only amplify the noise in the market. Instead, I talk to top academics, scientists, and entrepreneurs. They tell us where technology is heading and what the physical limits are. Investors should listen to ‘development of basic science and technology’ rather than ‘price’.”

He illustrated his approach with examples like NVIDIA, which he recognized not just as a graphics chip manufacturer, but as a platform maximizing “computational efficiency.” He anticipated the growing importance of accelerated computing as Moore’s Law approached its limits.

When it comes to valuing rapidly growing companies, he dismisses the search for “growth stocks at reasonable prices (GARP).” Truly exceptional companies, he argues, are rarely “cheap,” and understanding the sustainability of their growth is more important than fixating on current valuations.

Regarding Tesla and Elon Musk, he acknowledged the criticism but praised Musk’s commitment to innovation in manufacturing and energy solutions. He views Tesla as more than just a car company, but as a combination of energy infrastructure and robotics, and believes its founder’s ambitions could overcome significant physical constraints.

His advice to young investors is simple: “Play a different game.” Avoid getting caught up in the same short-term cycles as everyone else. Instead, focus on companies solving fundamental global problems and riding the wave of technological progress, and maintain a patient, long-term perspective.
