The Investment Answer: Learn to Manage Your Money & Protect Your Financial Future

By Daniel C. Goldie and Gordon S. Murray

Quick Summary

Goldie and Murray distill the essential principles of sound investing into five key decisions that every investor must make: whether to hire an advisor, how to allocate assets, how to diversify, whether to use active or passive strategies, and when to rebalance. Endorsed by Nobel laureates and industry leaders, this concise guide argues that the traditional financial services industry systematically fails investors and that simple, low-cost, disciplined investing outperforms complex, expensive approaches.

Detailed Summary

The Problem with Traditional Finance

The book opens with four representative scenarios illustrating how ordinary investors are failed by the financial industry: Ron and Judy who have no idea what they are paying in fees or whether their results are good; Betty who invested too conservatively in CDs and now cannot maintain her lifestyle; Steve who spends enormous time stock-picking with poor results; and Amy who panic-sold during the 2008 crash and has sat in cash ever since. These scenarios establish the need for a simple, evidence-based framework.

The authors' backgrounds lend credibility: Murray had a 25-year Wall Street career interfacing with the most sophisticated institutional investors, while Goldie is a CFA and CFP with decades of advisory experience. Their shared conclusion is that Wall Street's interests are systematically misaligned with those of individual investors.

Decision 1: The Do-It-Yourself Decision

The first decision is whether to manage money yourself, use a retail broker, or hire an independent fee-only advisor. The book strongly advocates for independent, fee-only advisors who have a fiduciary duty to clients, as opposed to retail brokers whose compensation through commissions creates conflicts of interest. Guidelines for selecting a qualified fee-only advisor are provided.

Decision 2: The Asset Allocation Decision

Asset allocation -- the division of a portfolio among stocks, bonds, and other asset classes -- is presented as the most important determinant of long-term returns and risk. The impact of volatility on compound returns is explained: a portfolio that loses 50% must gain 100% to recover, making volatility reduction through proper allocation essential. The relationship between risk and return is formalized.

Decision 3: The Diversification Decision

Diversification across and within asset classes is presented as the primary tool for reducing portfolio risk without sacrificing expected return. The size effect (small-cap stocks historically outperform large-cap over long periods) and the value effect (value stocks historically outperform growth stocks) are presented as empirically validated factors that should inform diversification decisions.

Decision 4: Active versus Passive

The active versus passive debate is resolved firmly in favor of passive (index) investing. The authors present the evidence that active fund managers as a group cannot consistently outperform their benchmarks after fees, referencing the work of William Sharpe and Eugene Fama. The arithmetic of active management -- that the average actively managed dollar must underperform the average passively managed dollar by the cost of active management -- is presented as inescapable logic.

Decision 5: Rebalancing

The final decision involves periodic rebalancing to maintain target asset allocations. As different asset classes appreciate or depreciate at different rates, the portfolio drifts from its target allocation, potentially taking on more or less risk than intended. Systematic rebalancing enforces a discipline of selling high and buying low.

Alternatives and Conclusion

The book briefly addresses hedge funds, private equity, and commodities, generally concluding that these alternatives are inappropriate for most individual investors due to high fees, illiquidity, and lack of transparency. The final message is empowering: everyone can succeed as an investor by making these five decisions well.
