One of the most common pieces of investment advice is simple:
"Just diversify."
And to be clear — diversification works.
Owning a broad mix of stocks, sectors, and asset classes reduces the impact of any single company or industry declining. It helps smooth volatility and lowers the risk of a catastrophic loss from one bad investment.
But diversification has limits.
There is a type of risk that cannot be diversified away — no matter how many ETFs or funds you own.
That risk is market risk.
Understanding the difference between diversifiable risk and market risk is essential for building portfolios that are not only growth-oriented, but also resilient.
The Two Types of Risk
When we think about equity investing, there are generally two broad categories of risk.
1. Company-Specific Risk (Diversifiable Risk)
This is the risk that something goes wrong with an individual company:
- A failed product launch
- A regulatory issue
- Poor management decisions
- Competitive disruption
If you own a single stock, this risk can be significant.
If you own 500 stocks across multiple sectors, the impact of one company becomes minimal. That is the power of diversification.
Company-specific risk can be reduced — and largely eliminated — through broad exposure.
2. Market Risk (Systematic Risk)
Market risk is different.
This is the risk that affects nearly all equities at the same time:
- Recessions
- Rising interest rates
- Financial crises
- Broad risk-off environments
When markets decline broadly, correlations between stocks tend to increase. Even well-diversified portfolios often fall together.
You can own:
- U.S. equities
- International equities
- Growth and value
- Large cap and small cap
And still experience meaningful losses when markets sell off.
This is not a failure of diversification.
It is the reality of systematic risk.
Why Traditional Model Portfolios Still Experience Drawdowns
Many model portfolios are built around risk categories:
- Conservative
- Moderate
- Growth
- Aggressive
Typically, the difference between these portfolios is the percentage allocated to equities versus bonds.
While this framework makes sense, it does not eliminate market exposure. A 60/40 portfolio may decline less than a 90/10 portfolio in a downturn — but it still carries equity risk.
Diversification reduces concentration risk.
It does not remove broad market exposure.
And for many investors, that distinction becomes most important during periods of volatility.
Diversification Spreads Risk. Hedging Reduces It.
Diversification answers the question:
"How do I avoid being overly exposed to one investment?"
Hedging answers a different question:
"How do I reduce downside exposure to the overall market?"
This is where defined outcome strategies and risk-managed overlays can play a role.
Rather than attempting to predict when markets will fall, hedging strategies can be structured to provide:
- Partial downside protection
- Defined loss thresholds
- More stable return profiles
For example, options-based overlays such as collars or structured buffers can limit the impact of severe market declines while maintaining participation in long-term growth.
These approaches are not designed to eliminate risk entirely — that would come at too high a cost. Instead, they aim to make market risk more intentional and measurable.
A More Thoughtful Approach to Model Portfolios
Instead of thinking only in terms of stock/bond percentages, portfolios can also be structured around risk parameters.
For example:
- A growth-oriented investor may accept higher volatility but still benefit from defined downside guardrails.
- A balanced investor may seek steady compounding with protection against extreme drawdowns.
- A more defensive investor may prioritize capital preservation while maintaining some exposure to long-term equity growth.
In each case, diversification remains foundational.
But layering in risk management tools can help address the portion of risk that diversification alone cannot solve.
Why This Matters
Markets move in cycles.
Periods of growth are often followed by periods of contraction. Over long horizons, equities have historically trended upward — but the path is rarely smooth.
Investors often underestimate how emotionally challenging drawdowns can be. And emotional decisions during downturns can have lasting consequences.
By recognizing that diversification and hedging serve different purposes, portfolios can be designed more intentionally:
- Diversify to reduce concentration risk.
- Hedge to manage market-wide risk.
- Align the structure with your specific time horizon and tolerance for volatility.
Final Thoughts
Diversification is essential. It remains one of the most powerful tools in portfolio construction.
But it is not a complete solution.
You cannot diversify away market risk.
You can, however, design portfolios that acknowledge it — and manage it thoughtfully.
For investors seeking long-term growth while being mindful of downside exposure, the conversation should extend beyond asset allocation percentages and into how risk itself is structured.
A well-built portfolio is not simply diversified.
It is intentional.
