Revolutionary Common Sense for Investing

The book defines common sense as “the endowment of natural intelligence” possessed by rational beings and the “plain wisdom” inherited by every man. Thomas Paine’s series Common Sense lit the fuse of the American Revolution, and common sense is not always abundant. To invest successfully, you must apply revolutionary common sense consistently to your investment strategy, selection, and performance. Investing is an act of faith, but your guiding principle should be appreciation for the long-term. You must maintain a tolerable balance between risk and return, which is always individualistic.

Asset Allocation – The Key to Investment Success

Asset allocation is critical when planning your investment portfolio since it largely determines its outcome. It entails selecting asset classes and the percentage of your portfolio invested in each. Achieving investment goals demands a disciplined approach and, most importantly, a focus on long-term goals. Index strategies offer the best choice for long-term investors looking to maximize their returns. However, many mutual fund investors are more enthusiastic about the process of investing, failing to understand the economics thereof. When selecting mutual funds, it’s not advisable to look at past performance, as statistics show that the most successful funds do not maintain their edge for long.

The Mutual Fund Industry’s Betrayal

The mutual fund industry has abandoned its original principles of service and fiduciary responsibility. It has become a marketing-driven business that disguises poor performance and exploits investors through high fees. Fund managers prioritize their own interests instead of their investors’. As a result, the industry resembles a closed cartel that desperately needs restructuring and transparent governance. Investors need to demand change and invest elsewhere if necessary.

The Two Forces Behind American Markets

The stock and bond markets in America are driven by two historical forces: market fundamentals and speculation or trading based on opinions and emotions about the market. While investors trust their fund managers to generate positive returns, active managers often fail to outperform appropriate market indexes. It’s been proven that stock managers have difficulty beating the market over the long term. Meanwhile, the most cost-effective approach to investing is to dispense with the active manager and simply buy a representative cross section of the entire market. So-called passive investors never beat the market. But they never lag behind it, either. This syllogism: the sum of active and passive gross returns equals the market’s gross return; active investors have higher costs than passive investors, therefore, passive investors earn higher net returns.

Three Asset Classes for Investors

The importance of risk in investment strategy and the need for a diversified investment portfolio consisting of three asset classes: stocks, bonds, and cash.

Investors looking to maximize returns while minimizing risk should focus on three primary asset classes: stocks, bonds, and cash. These classes serve different purposes, with stocks providing high returns, bonds generating income, and cash stabilizing principal and reducing risk.

Risk is the most crucial element in any investment strategy, and investors must balance risk and return. High returns typically mean high risks, while low risks lead to low returns. However, investors can mitigate risk by diversifying their portfolios. By holding both stocks and bonds, investors can reduce their risk while simultaneously enhancing their overall portfolio returns, rather than exposing themselves to a bear market.

Unfortunately, the industry has moved away from guiding principles, and investors must hold fund managers to a higher level of trusteeship responsibility. Allocating assets based on long-term goals and periodically rebalancing is crucial for success. It’s important to note that this discussion of risk applies to the market as a whole, not individual stocks or bonds. With this in mind, investors can construct a well-diversified investment portfolio that balances risk and reward.
