How to invest like Jack Bogle

20 January 2025

Jack Bogle, the founder of Vanguard Group, is revered as a revolutionary in the investment world. His pioneering work in index fund investing has transformed the landscape, favouring the everyday investor with strategies that were once the preserve of the elite. Bogle’s investment philosophy revolves around simplicity and cost-effectiveness, making him a hero to individual investors worldwide.

 

THE MAN WHO DEMOCRATISED INVESTING

Born in 1929, Bogle faced the adversities of the Great Depression, which shaped his view of the financial world. After attending Princeton University, where he studied economics and investment, he wrote his thesis on mutual funds, critiquing the industry for its high costs and poor performance relative to market indices. This laid the groundwork for his future endeavours.

Bogle's career trajectory took him through various roles in the investment sector, but it was the founding of Vanguard Group in 1974 that cemented his legacy. He structured Vanguard as a client-owned mutual fund company, where the fund shareholders own the funds, which in turn own Vanguard. This unique structure aligned the company's interests with those of its investors.

 

CORE INVESTMENT PRINCIPLES

Bogle’s investment strategy is underpinned by a few core principles.

Low-cost index funds: Bogle introduced the first index mutual fund for individual investors. He believed that most mutual funds fail to beat the market after accounting for fees and expenses. Therefore, the most effective strategy for the majority of investors is to invest in a low-cost index fund that tracks a broad market index.

Long-term investing: Bogle advocated for a long-term approach to investing. He believed that short-term market trends are unpredictable and that investors should remain invested over the long term to reap the rewards of market growth.

Focus on simplicity: His investment approach favours simplicity over complexity. Bogle advised individual investors to invest in a few broad-based index funds and avoid the pitfalls of frequent trading and timing the market.

Minimise costs: Bogle repeatedly stressed that costs are one of the biggest drags on investment performance. He argued that by minimising fees, investors can significantly increase their net returns over the long term.

Stay the course: Bogle encouraged investors to maintain their investment strategy despite market volatility. He believed in a disciplined approach, sticking to one's investment plan regardless of market conditions.

 

INVESTING LESSONS FROM JACK BOGLE

The impact of fees on investment returns: Bogle taught that fees, no matter how small they seem, can compound just as returns do, significantly eating into an investor's profits over time.

The wisdom of the market: He believed in the 'wisdom of the market'—that it is not easy, if not impossible, to outperform the market consistently through active management after accounting for transaction costs and taxes.

Investing, not speculating: Bogle differentiated between investing and speculating, emphasizing that the former is the more reliable path to building wealth over time.

The power of compounding: He often highlighted the power of compounding returns, noting that the longer you hold an investment, the more potential it has to grow exponentially.

The virtue of simplicity: Bogle's approach reminds us that a simple, well-diversified portfolio is often more effective than a complex strategy that attempts to beat the market.

 

Jack Bogle’s legacy is profound yet straightforward: he upended an industry by proving that investment success doesn't require complex strategies or access to privileged information. Instead, it can be achieved by anyone with a clear, low-cost, long-term and disciplined approach. His principles have paved the way for millions to participate in the stock market.
