Passive vs. Active Investing: Why and How I Use Both
One of the most common questions I receive from clients is whether they should invest in passive index funds or actively managed funds. My answer is simple: both have a place in a well-designed portfolio.
For most investors, I believe passive investing should form the foundation of a long-term investment strategy. Index funds have transformed investing by providing broad market exposure, low costs, and tax efficiency. Decades of research have shown that, after fees, many actively managed funds fail to outperform their benchmark over long periods.
That doesn't mean active management has no value. It simply means that active management should be used selectively and intentionally.
Why Passive Investing Works
Passive funds seek to match the performance of an index rather than beat it. Instead of trying to predict which companies will outperform, they own the entire market or a representative portion of it.
There are several advantages:
Lower investment costs
Broad diversification
Greater tax efficiency
Reduced manager risk
Consistent exposure to long-term market growth
These benefits make passive funds an excellent core holding for most portfolios. Investors spend less time worrying about whether they own the "right" fund and more time benefiting from the long-term growth of the market.
The Challenge for Active Managers
In highly researched markets like large U.S. companies, thousands of professional investors analyze the same financial statements, earnings reports, and economic data every day. Information is absorbed into stock prices remarkably quickly.
Because of this intense competition, consistently outperforming the market after fees has proven extremely difficult. This is one of the primary reasons I generally prefer low-cost index funds for broad U.S. equity exposure.
Where Active Management Can Add Value
Not every market is equally efficient. Some areas of the market have less analyst coverage, lower liquidity, greater political or regulatory uncertainty, or rapidly changing competitive landscapes. These characteristics can create opportunities for experienced portfolio managers to add value through research and security selection.
Examples include:
Emerging markets
Frontier markets
Certain small-cap sectors
Specialized thematic investments
Niche fixed-income markets
These areas often require deeper fundamental research than simply buying the entire market.
Rather than trying to outperform everywhere, I believe active management is best used where skilled managers have a greater opportunity to identify risks and opportunities that may not yet be fully reflected in market prices.
Using Active Funds as a Tactical Tilt
Another area where I selectively use active management is to increase exposure to high-conviction growth themes.
Innovation doesn't happen evenly across the economy. Industries such as artificial intelligence, cybersecurity, cloud computing, robotics, biotechnology, and digital infrastructure often experience rapid changes as new technologies emerge and market leaders evolve.
Instead of attempting to pick individual stocks, I may use carefully selected, low-cost active funds to modestly tilt portfolios toward these long-term growth areas when they align with a client's objectives and risk tolerance.
The goal isn't to chase headlines or make dramatic market timing decisions. It's to thoughtfully position a portion of a portfolio in areas where active research may help identify companies with durable competitive advantages or avoid businesses that may struggle as industries evolve.
Building Portfolios with the Best of Both Worlds
My investment philosophy isn't about choosing between passive and active investing. It's about using each where it has the greatest potential benefit.
For many portfolios, that means:
Using low-cost passive funds as the core allocation.
Adding selective active managers in less efficient market segments.
Making measured tactical tilts toward compelling long-term investment themes when appropriate.
Keeping costs disciplined while maintaining broad diversification.
This approach seeks to combine the strengths of passive investing—low costs, diversification, and consistency—with the flexibility to pursue opportunities where active management may provide additional insight.
The Bottom Line
Investing isn't about finding a single strategy that works all the time. It's about using the right tools for the right job.
Passive investing has earned its place as the foundation of many successful portfolios because it provides efficient, low-cost exposure to long-term market growth.
At the same time, there are segments of the market where experienced managers, rigorous research, and disciplined security selection may offer opportunities that broad indexes cannot.
For my clients, the objective isn't to be "all passive" or "all active." It's to build a diversified portfolio that uses both approaches thoughtfully, always with the goal of helping them pursue their long-term financial objectives while managing risk along the way.
