The "good enough" portfolio: why your second-best allocation usually beats your first.

Optimization is seductive, but the portfolio you'll actually stick with through three bad quarters beats the one that looks perfect on paper. A practical case for boring, durable allocation choices.

The “good enough” portfolio is the one you’ll actually stick with when things go sideways. That’s the whole argument.

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 optimized for the assumptions that go into the model, not for the psychological reality of watching a number drop 30% while the headlines say things are getting worse.

What Does “Good Enough” Actually Mean?

A good-enough portfolio isn’t sloppy. It’s built to survive your decision-making in bad years, not just to perform well in good ones. Jeff Judge has spent more than two decades watching clients handle real market conditions, and he’s seen more damage done by technically superior allocations that got abandoned at the bottom than by imperfect allocations that got held.

Three things define it.

You understand 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 during a bad year.” That’s enough. The test: can you recite that reasoning to yourself at 2 a.m. in a bad March? If yes, you’ll hold. If not, 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 is the Sharpe ratio?” Most people answer the hypothetical honestly and discover 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. Boring is a feature. A portfolio that generates regular anxious check-in calls usually signals the allocation is wrong, not that the client is diligent.

The FAQ on Good Enough Portfolios

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 actually misallocated?

Ask whether your discomfort comes from volatility or from genuine belief that something is wrong with the construction. Volatility discomfort is normal and manageable with better framing. Belief that the allocation is wrong usually means it is. Those need different fixes.

Does “good enough” mean ignoring performance entirely?

No. It means you evaluate 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’s 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 be right for a 5-year one. When retirement dates shift, when large expenses appear, when income changes significantly, revisit the allocation. The goal is durability, not permanence.

The Behavior Gap Is Real, and It Costs 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 a decline. They buy after a run-up. They underperform the very funds they own.

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: According to 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 meaningful gap between what Social Security provides and what their retirement actually costs. That bridge doesn’t survive getting dismantled twice in a bad decade.

A portfolio returning 7% annually that you abandon twice in ten years will net you less than a portfolio returning 6% held continuously. The behavior matters more than the allocation in most real-world scenarios.

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, but 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.
