Is Your Portfolio “Over-Diversified”? The Case for Intentional Investing
In the world of investing, diversification is often described as one of the most important principles. However, in some cases, adding more investments without a clear strategy can lead to unintended overlap and complexity.
When additional holdings do not serve a distinct purpose, a portfolio may become more difficult to manage without meaningfully improving diversification.
At BDB Wealth Advisors, we often refer to this concept as “diworsification.”
1. The Illusion of Choice: Why 20 Funds Isn’t Always Better
A common sight in modern brokerage accounts is a “collection” of 15 to 20 different mutual funds and ETFs. On the surface, this may appear well-diversified. However, a closer review may reveal that many of these funds hold similar underlying positions.
The Overlap Trap
If you own multiple “growth” funds or sector-focused ETFs, you may have an unintended concentration in a relatively small group of companies.
In these situations, investors may not be achieving meaningful diversification, but rather holding similar exposures across multiple investments.
The Dilution Effect
By owning a large number of similar funds, a portfolio may begin to resemble a broad market index while also introducing additional layers of cost and complexity.
This can make it more difficult to evaluate how each investment contributes to the overall portfolio.
2. A More Intentional Approach to Portfolio Construction
Diversification is not simply about the number of holdings in a portfolio—it is about how those investments interact with one another.
A more intentional approach often focuses on clearly defined roles within a portfolio.
Asset Class Distinction
Instead of overlapping investments, portfolios may be structured across distinct asset classes such as:
Domestic equities
International equities
Fixed income
Other diversifying assets
This can help ensure that each allocation serves a specific purpose within the overall strategy.
Factor-Based Considerations
Some portfolio strategies incorporate exposure to specific factors such as:
Value
Quality
Low volatility
By incorporating these elements, portfolios can be designed to behave differently than a traditional market-cap-weighted index, depending on market conditions.
Cost Awareness
Each additional fund may introduce its own expense ratio and potential transaction costs.
In some cases, streamlining investments may help reduce unnecessary costs and improve overall portfolio clarity.
3. Intentionality Over Activity
In today’s environment, it can be tempting to add new investments based on trends, headlines, or recent performance.
However, adding investments without a defined purpose may increase complexity without improving the overall structure of a portfolio.
The Core and Satellite Approach
Some investors utilize a “core and satellite” framework:
A core portfolio designed for broad market exposure
Smaller satellite positions that serve a specific role within the portfolio
This approach can help maintain structure while allowing flexibility where appropriate.
Is Your Portfolio Overly Complex?
Portfolios built over time can sometimes become a collection of overlapping ideas rather than a cohesive strategy.
In some cases, increased complexity may make it more difficult to identify:
underlying costs
overlapping exposures
overall portfolio alignment
Reviewing how investments work together can help provide greater clarity around long-term strategy.
The Bottom Line
Diversification remains an important principle in investing. However, more investments do not always result in more effective diversification.
In some situations, a more intentional approach—focused on clarity, structure, and defined roles—may help improve how a portfolio is organized and understood.
Because every investor’s situation is different, evaluating portfolio structure within the context of a broader financial plan can help support more informed decision-making.
