3 books17 followersHi. I'm Cullen. Thanks for your interest in my work. I've written three books, Pragmatic Capitalism, Your Perfect Portfolio and Sleepy Bear's Sleepy Time. The first two are wonky diatribes related to my day job as a financial analyst and the last one is a short children's book that I wrote for my baby daughters.
I hope you enjoy them and don't hesitate to send me a note if you want to get in touch. Thanks and take care!

This was a very good book. Roche is better known for his macroeconomic work, but I enjoyed how he took a "big picture" look at the world of portfolio construction from many different angles.
The book is really two different books. Part 1 is a general overview of essential principles. There's nothing earth shattering in here, but it's a good foundational understanding of why part 2 is constructed the way it is.
Part 2 is a ton of different strategies and styles. Some of them are really basic. Some of them are pretty confusing. But there's something for everyone in here.
What you won't find is some sort of holy grail strategy in here, which I think will disappoint some readers. But if you're looking for very practical and actionable ideas this is a great read. Solid 5/5.

I have selected this book as Stevo's Business Book of the Week for the week of 1/11, as it stands heads above other recently published books on this topic.

I greatly enjoyed Roche's look at different asset allocations and learned a lot. I especially liked his chapters on the Global Financial Asset Portfolio, Forward Cap, Retirement Bond Tent Strategy, and Defined Duration Strategy.
Unfortunately, Roche's highest performing portfolio yields 11.41% so this is not a get rich quick book. It is a "It is unlikely that you can beat the market. It is unlikely that you can time the market. You can only hedge risk and rebalance" book.

In "Your Perfect Portfolio," the book presents a clear and reassuring approach to managing money by addressing one of the most common struggles people face: the uncertainty of what to do after earning it. Instead of promoting complex strategies or chasing high returns, it encourages a shift in perspective toward aligning financial decisions with the timeline of one’s life. The central message is that financial anxiety does not come from a lack of intelligence, but from a mismatch between how people think and how markets behave. By understanding this gap and restructuring how assets are used over time, individuals can build a plan that feels stable and sustainable. The book ultimately reframes investing as a personal system designed to support future needs rather than a competitive game to beat the market.
A major theme explored is the powerful role of human psychology in financial decision making. While markets are often discussed in terms of data and logic, the book emphasizes that emotions play a far greater role in real life outcomes. Human beings evolved to respond quickly to danger, and this instinct still operates when facing financial losses. When markets decline, people often feel an overwhelming urge to act, usually by selling at the worst possible time. This reaction, though natural, tends to harm long term wealth rather than protect it. Because of this, the real challenge is not mastering financial models but managing one’s own behavior. A strategy that looks ideal on paper becomes useless if it cannot be followed during periods of stress. Therefore, the best portfolio is not the one with the highest theoretical return, but the one that an individual can maintain consistently through both good and bad times.
Another important idea is redefining personal identity in relation to money. Many people think of themselves as investors, which creates pressure to outperform markets and make bold decisions. The book suggests a more grounded identity: that of a saver. Most individuals are not directly funding businesses or creating new production, but rather setting aside income to preserve purchasing power over time. This shift reduces the need for constant action and replaces it with a focus on stability and long term security. By seeing money as something to protect rather than gamble with, decision making becomes calmer and more rational. This perspective also highlights that success is less about beating others and more about ensuring that future needs are met reliably.
The discussion then moves to common investment approaches and their limitations. A theoretical starting point is owning a broad representation of global assets, which removes the need to make active choices. Simpler versions of this idea, such as diversified portfolios with stocks and bonds, are widely used. However, the book points out that these default strategies are often misunderstood. For example, a mix that appears balanced may still be heavily influenced by the more volatile components, especially stocks. During market downturns, this imbalance becomes clear as losses can still be significant. This reveals that traditional allocations are not always as safe as they seem, and relying on them without understanding their behavior can lead to unpleasant surprises.
To address these shortcomings, the book explores alternative approaches that aim to improve resilience or capture growth in different ways. Some strategies focus on tilting investments toward specific characteristics that have historically performed well, while others look ahead to future economic trends rather than relying on past performance. These methods attempt to increase returns or better position a portfolio for long term changes in the global economy. However, they often require patience and emotional discipline, as they may underperform for extended periods. Another approach introduces strategies that react to market movements, allowing investors to benefit from both rising and falling conditions. These can provide protection during severe downturns, but they also come with trade offs, such as inconsistent performance during stable periods.
For those who prefer a more stable experience, the book introduces defensive strategies designed to reduce volatility and improve balance. One such approach aims to distribute risk more evenly across different types of assets, rather than allowing one category to dominate. Another divides investments into categories that perform well under different economic conditions, ensuring that at least part of the portfolio is always working effectively. There are also methods that focus on generating regular income, which can provide psychological comfort during uncertain times. Additionally, the book highlights the importance of preparing for major life transitions, such as retirement, by adjusting the balance of assets to reduce the impact of market fluctuations during critical periods. These strategies emphasize durability over maximum growth, prioritizing the ability to stay invested over the long term.
The most important concept introduced is the idea of aligning investments with time horizons, often referred to as duration. Instead of focusing solely on potential returns, the book encourages matching each type of asset with the period in which the money will be needed. Short term needs should be covered by stable and predictable assets, while long term goals can be supported by more volatile investments that have time to recover from downturns. This approach removes much of the uncertainty associated with market fluctuations, as it ensures that essential expenses are not dependent on unpredictable conditions. By separating financial goals based on timing, individuals can create a system that balances safety and growth more effectively.
A practical implementation of this idea involves dividing financial resources into two main components. The first provides security through stable investments that cover upcoming expenses over a defined period. This creates a sense of certainty and reduces the need to react to short term market movements. The second component focuses on long term growth, allowing riskier assets to compound over time without interruption. Because immediate needs are already secured, there is less pressure to sell during downturns, which helps preserve long term gains. Maintaining this structure requires periodic adjustments, where assets are rebalanced based on changing conditions rather than fixed schedules. This disciplined approach helps ensure that the portfolio remains aligned with both market realities and personal needs.
Ultimately, the book presents a framework that integrates emotional awareness with practical financial planning. It acknowledges that uncertainty and fear are natural, but shows how they can be managed through thoughtful design rather than constant action. By focusing on time, behavior, and alignment, individuals can build portfolios that are not only effective but also comfortable to live with. This reduces the temptation to make impulsive decisions and increases the likelihood of long term success. The emphasis is not on finding a perfect formula, but on creating a system that works reliably in the real world.
In conclusion, "Your Perfect Portfolio" offers a thoughtful and practical perspective on managing money by emphasizing the importance of aligning assets with life’s timeline. It shows that financial success is less about chasing returns and more about building a structure that can withstand both market volatility and human emotion. By shifting from an investment mindset to a saving mindset, understanding the limits of traditional strategies, and adopting a time based approach, individuals can create a plan that provides both stability and growth. The book reinforces that the most effective portfolio is one that matches personal needs, reduces anxiety, and allows long term compounding to work without interruption.

An informative and accessible glimpse into the art & science of building portfolios. Cullen does a masterful job of giving you options, explaining the risks and opportunities of each, and offering his own portfolio strategy without force feeding it down your throat (try reading a book on private credit written by a private credit asset manager).
Cullen's defined duration approach has been hiding in plain sight. Institutions have been using it for years to effectively match assets with present and future spending needs. Instead, many focus on access to sexy alternative investments rather than the practical strategies used by large banks and pension funds.
Building portfolios to attempt to outperform benchmarks like the S&P 500 is like eating stuffed crust pizza with extra cheese and four toppings. It feels good in the moment but 9 times out of 10 you'll be on the toilet the next day. Defined Duration investing is like eating a farm-to-table dinner. It tastes good and feels good after.
My only critique: For those uninformed on some of the more technical terms, Sharpe & Sortino ratios for example, a short, playful glossary could have helped.

A solid compilation of strategies for asset allocation. Nicely formatted with the theory behind the strategy, pros and cons, and thoughts on which investor might want to consider each strategy.
I particularly appreciated Roche's notion that what most of us consider to be investing is actually just saving. Investing is what we do for ourselves to increase our earning power - through education, diversifying our personal interests.
A few interesting historical tidbits, but largely (as one would expect) pretty dry. Happily, because of the format of the book, skimming strategies that are not of interest is easy to do without missing much.

Should be called playing with portfolios!
This is just a guy pontificating on the latest and greatest model/approaches. I think it overlaps greatly, if not creates confusion - 2 things that don’t help investor. I didn’t care for his personal investment approach at all. Also, his views/attempts at financial planning are classic investment salesperson stuff. Let alone shows his youth.

I thought this was a solid read for those looking to learn more about different types of portfolios. The author did a good job of tying in concepts such as investor time horizons that most likely don't reflect on enough.

This book was fantastic. It's loaded with data and educational material. I loved that it was actionable unlike most investing books.
