Examples

3 cases

The Power of Compounding

A young investor starts saving $100 per month at age 25 and continues to do so until age 65. Assuming an average annual return of 7%, the investor will have saved over $1 million by age 65, demonstrating the power of compounding and the importance of starting early.

OutcomeThe investor is able to retire comfortably, thanks to the power of compounding and the discipline of regular investing.

The Importance of Diversification

An investor puts all their money into a single stock, which performs well for a few years but then crashes. The investor loses a significant portion of their portfolio, demonstrating the importance of diversification.

OutcomeThe investor learns a valuable lesson about the importance of diversification and rebalances their portfolio to reduce risk.

The Impact of Costs and Taxes

An investor invests in a high-cost mutual fund, which charges 2% in annual fees. Over time, the fees eat into the investor's returns, demonstrating the impact of costs and taxes on investment returns.

OutcomeThe investor switches to a low-cost index fund, reducing their costs and increasing their potential returns.

Common mistakes

5 traps

Trying to Time the Market

Trying to time the market is a common mistake that can lead to poor investment returns. It's impossible to predict with certainty when the market will go up or down, and trying to do so can result in missing out on potential gains or selling at the wrong time.

Following Past Performance

Following past performance is another common mistake that can lead to poor investment returns. Past performance is not a reliable indicator of future results, and investing in a product or fund simply because it has performed well in the past can be a recipe for disaster.

Ignoring Costs and Taxes

Ignoring costs and taxes is a critical mistake that can eat into your investment returns. Costs and taxes can have a significant impact on your investment returns, and failing to consider them can result in lower returns than expected.

Not Diversifying

Not diversifying your portfolio is a mistake that can increase risk and reduce potential returns. Failing to spread your investments across different asset classes can result in a portfolio that is overly concentrated in one area, increasing the risk of losses if that area performs poorly.

Not Having a Long-Term Perspective

Not having a long-term perspective is a mistake that can lead to poor investment returns. Investing is a long-term game, and having a short-term focus can result in making emotional decisions based on short-term market fluctuations rather than sticking to a well-thought-out investment plan.

Origin story

How this framework came to be

The Bogleheads' investment philosophy was developed by a community of individual investors who follow the investment principles of John Bogle, the founder of Vanguard. The philosophy is based on the idea that investing should be a simple, low-cost, and long-term process, rather than a complex and expensive one.
