Peter Lazaroff Releases The Perfect Portfolio

About Plancorp | Investment Strategy

 Derek Hartley By: Derek Hartley
The Principles Behind Plancorp's Investment Philosophy, Now Available in One Book
 
For more than 40 years, Plancorp has helped clients navigate bull markets, bear markets, economic uncertainty, and life's biggest financial decisions. While markets, products, and headlines have changed dramatically over the years, the principles guiding our investment philosophy have remained remarkably consistent.
Today, we're excited to share those principles with a broader audience through the release of The Perfect Portfolio: A Proven Guide to Smart Investing for Long-Term Success by Peter Lazaroff, Chief Investment Officer here at Plancorp Wealth Management.
 
Available beginning September 22, 2026, The Perfect Portfolio brings together decades of investment experience, academic research, behavioral finance, and real-world lessons learned from helping thousands of families manage wealth through changing market conditions.
 

A Different Conversation About Investing

The book is focused on one primary question: How to build an investment strategy you can actually stick with.


At Plancorp, we've long believed that successful investing isn't about predicting markets, chasing performance, or finding the next great opportunity. It's about creating a thoughtful plan, staying disciplined, managing emotions, and keeping your portfolio aligned with your goals through every stage of life. Those same ideas form the foundation of The Perfect Portfolio.

 
As Peter often says, investing success comes from process, not prediction.
 

Why We Believe Every Investor Should Read This Book

Whether you're a long-time client, someone exploring a relationship with Plancorp, or simply an investor looking to make better financial decisions, the lessons in this book are designed to help you:

  • Understand what actually drives long-term investment success
  • Avoid common behavioral mistakes that can derail financial plans
  • Build a portfolio aligned with your goals, timeline, and risk tolerance
  • Make sense of market volatility without reacting emotionally
  • Develop a framework for making better investment decisions over time
  • Focus on what matters most while tuning out the noise that dominates financial headlines

The central message is simple: The perfect portfolio isn't the one with the highest return. It's the one you can stick with.
