The good enough portfolio is the one you’ll actually hold when things go sideways. That’s the whole argument, and it’s stronger than it sounds.
There’s a version of your portfolio that optimizes perfectly for your risk tolerance, time horizon, tax situation, and expected return profile. Academic finance has detailed models for it. Your advisor probably has software that runs the calculation. And most people abandon it sometime in the second or third bad quarter. Not because they lack discipline. Because optimized portfolios are built for the assumptions in the model, not for the psychological reality of watching a number fall 30% while the headlines say things are getting worse.
Key Takeaways
- A good enough portfolio is one you can hold through a bad market, not the one that scores best in a model.
- The behavior gap is real: investors lag the funds they own by selling after declines and buying after run-ups.
- The maximum Social Security benefit at full retirement age in 2026 is $4,152 a month, so the portfolio still has to close the gap.
- A 60/40 held through a 35% decline beats an 80/20 you abandon at the bottom.
- Revisit your allocation when your goals change materially, not every time the headlines do.

He helps families and business owners think more clearly about building durable portfolios, using the R.U.D.D.E.R. Method™, the financial planning process Jeff developed. “The portfolio that wins is almost never the most optimized one. It’s the one a real person can sit through a brutal quarter and still own the next morning.”
What Does a “Good Enough” Portfolio Actually Mean?
A good enough portfolio isn’t sloppy. It’s built to survive your decision-making in bad years, not just to perform in good ones.
Three things define it:
You can explain why it’s built the way it is. Not the mathematical derivation. The plain-English logic. “I’m 60/40 because I need this money in twenty years, I can tolerate some volatility, but I need to sleep at night in a bad quarter.” That’s enough. If you can recite that reasoning to yourself at 2 a.m. in a bad March, you’ll hold. If you can’t, you won’t.
You’ve stress-tested it emotionally, not just mathematically. “What would I actually do if this dropped 25%?” is a more important question than “what’s the Sharpe ratio?” Most people answer the hypothetical honestly and learn something about their real risk tolerance they didn’t know before they asked.
It’s boring. Boring means you’re not tweaking it based on articles you read. You’re not calling your advisor after every Fed announcement. A portfolio that generates regular anxious check-ins usually signals a wrong allocation, not a diligent client.
| Characteristic | Good Enough | Red Flag |
|---|---|---|
| You can explain it in plain terms | Yes | Requires a spreadsheet to justify |
| You’ve stress-tested a real 25% drop scenario | Yes | Only modeled mathematically |
| News events don’t trigger weekly check-ins | Correct | Headlines send you to the phone |
| Held through at least one real correction | Yes | First real test still ahead |
What Should You Ask About a “Good Enough” Portfolio?
Is it irrational to accept a suboptimal portfolio?
Only if you’d actually hold the optimal one. The rational choice maximizes expected outcomes given your real behavioral constraints, not your theoretical ones. A 60/40 you hold through a 35% decline beats a theoretically superior 80/20 you abandon at the bottom. Every time.
How do I know if my portfolio is “good enough” versus genuinely misallocated?
Ask whether your discomfort comes from volatility or from real belief that something is wrong with the construction. Volatility discomfort is normal and fixable with better framing. Belief the allocation is structurally wrong usually means it is. Those need different fixes.
Does “good enough” mean ignoring performance entirely?
No. It means evaluating performance relative to what the allocation is supposed to do, not relative to whatever happened to go up this quarter. A 60/40 that underperforms a 100% equity portfolio in a bull market isn’t failing. It’s doing exactly what it was designed to do.
When does “good enough” stop being good enough?
When your goals change materially. A 60/40 built for a 20-year horizon may not fit a 5-year one. When retirement dates shift, large expenses appear, or income changes significantly, revisit the allocation. The goal is durability, not permanence.
Is the Behavior Gap Costing You Real Money?
There’s a well-documented gap between what investment funds return and what investors in those funds actually earn. It exists because people move in and out of positions at the wrong times. They sell after declines. They buy after run-ups. They underperform the very funds they own.
Per the SEC, individual investor returns lag the funds they own by a meaningful margin, primarily because of poorly timed decisions during volatile periods. The fix isn’t willpower. It’s building an allocation boring enough that you stop making those moves.
Here’s the practical version of why this matters. Per the Social Security Administration, the maximum monthly Social Security benefit at full retirement age in 2026 is $4,152. Most people need their investment portfolio to bridge a real gap between what Social Security provides and what retirement actually costs. That bridge doesn’t survive being dismantled twice in a bad decade.
| Scenario | Portfolio Return | Behavioral Drag | What Happens Over 20 Years |
|---|---|---|---|
| Optimized 80/20, abandoned twice in downturns | 8% stated | Significant (sell low, buy high) | Meaningful shortfall vs. stated return |
| Boring 60/40, held continuously | 6.5% stated | Minimal | Approaches stated return |
| Best case: right allocation AND held | Higher by design | Minimal | Maximum compounding |
Illustrative only. Actual results depend on specific timing, amounts, and market conditions.
The allocation matters. The behavior matters more.
Frequently Asked Questions
What is a good enough portfolio?
A good enough portfolio is an allocation built to survive your own decisions in a bad market, not just to look optimal in a model. It is simple enough to explain in plain language and durable enough that you hold it through a real decline.
Does a good enough portfolio mean accepting lower returns?
Not necessarily. It means accepting the highest return you can realistically hold without bailing out at the wrong time. A theoretically superior allocation you abandon in a downturn usually delivers worse real-world results than a simpler one you keep.
How often should I change my asset allocation?
Change it when your goals or circumstances change materially, such as a shifted retirement date, a large expense, or a meaningful income change. Reacting to headlines, Fed announcements, or a single bad quarter is the behavior that erodes long-term results.
What is the behavior gap in investing?
The behavior gap is the difference between what funds return and what investors in them actually earn. It comes from poorly timed moves, selling after declines and buying after run-ups, a gap the SEC has flagged for years.
What’s the Right Question to Ask About Your Portfolio?
Jeff tells clients something early in the planning relationship that catches some of them off guard: “We’re not trying to maximize your returns. We’re trying to maximize the probability that you reach your goals.” Those are related. They’re not the same.
Maximizing returns requires accepting volatility that most people, under real pressure, can’t sustain. Maximizing goal probability means building something durable enough to weather the conditions you’ll actually face, including the ones that feel like emergencies and aren’t.
Building a good enough portfolio starts with an honest conversation about what you’d actually do in a real decline, not what you think you’d do. If you’ve been through 2008 or 2020, you have data on that. If you haven’t, you’re estimating, and the estimate is usually optimistic.
The question isn’t “what’s the best portfolio I can build?” It’s “what’s the best portfolio I can hold?” Schedule a no-obligation call with Jeff to talk through what that looks like for your situation.
