Which market news should actually change your plan?
What if the markets turn against me? The financial press produces urgency daily because that's its job. Almost none of it should change a plan.
The financial press has to produce something every day. Markets don't cooperate by being interesting every day, so the gap gets filled with explanation: why stocks moved, what a data release means, what someone influential said about it.
Very little of it should change what you do. Not because it's wrong, but because it's answering a question that isn't yours. The press describes what happened this week. Your plan is about a period measured in decades.
The problem is that noise and signal arrive through the same channel, in the same tone, at the same volume.
The short answer. Ask three questions. Does this change what I need the money to do? Does it change the range of outcomes I was already planning for? Would I still think it mattered in five years? Almost nothing clears all three.
| The question | What it filters out |
|---|---|
| Does this change what I need the money to do? | Almost all market commentary, because your goals did not move |
| Does it change the range of outcomes I was planning for? | Declines, which the plan already assumed would happen |
| Would I still think it mattered in five years? | Nearly everything with a date on it |
The SEC's investor education arm makes the same point about working with a professional and what to expect from one: a process you can describe beats a forecast you cannot check.
Three questions that sort it.
Does this change what I need the money to do? Not what the portfolio is worth, what it has to accomplish. A market decline doesn't change your retirement date, your spending, or your obligations. A health diagnosis does. A job loss does. A child's changed circumstances does. If the news is about markets rather than about your life, the answer here is almost always no.
Does it change the range of outcomes I was already planning for? A good plan assumes markets fall substantially at unpredictable intervals, because they always have. A 20% decline is inside that assumption, not outside it. It feels like new information and isn't. What would be genuinely new is a change to the structural rules: tax law, withdrawal requirements, the treatment of an account type.
Would I still think this mattered in five years? Most market news fails this immediately. The few things that pass tend not to be the things leading the coverage.
What actually warrants a change.
For a household with a plan already running, the list is shorter than most people expect.
A change in your circumstances. Health, employment, family, a business event, an inheritance. These are the real triggers, and none of them appear in market coverage.
A change in the law. Tax rates, contribution and withdrawal rules, the thresholds for tax on wealth passing to your heirs, the treatment of inherited accounts. These change what's optimal in ways markets don't, and they're why a plan needs revisiting on a schedule rather than only when something feels wrong. See tax planning.
Drift in the portfolio itself. If a strong run has left one holding much larger than intended, your risk has genuinely changed. It just happened quietly rather than in the headlines. See what to do when one stock is too much of your portfolio.
A decline that creates an opportunity. Lower account values make Roth conversions cheaper, and realized losses become an asset that offsets gains for years. A bad market is genuinely useful if you're positioned to act rather than react.
Two of those four turn a decline into something to use rather than survive. That's only available to households who decided in advance what they'd do.
The economy is not the market.
A recurring source of confusion is assuming a weak economy means weak markets and a strong economy means strong ones.
The relationship is far looser than intuition suggests, for a structural reason: markets price expectations, while the economy reports what already happened. By the time a condition is documented well enough to be reported confidently, it has generally been in prices for some time. This is why markets frequently rise during genuinely poor news and fall during good news, which reads as irrational and isn't.
The practical consequence: a correct view about the economy doesn't reliably translate into a profitable view about markets. Anyone selling you the second on the strength of the first is skipping a step.
The risk that actually costs money.
Across decades of watching how households behave, the damage rarely comes from holding the wrong assets. It comes from not holding them long enough.
The pattern is consistent. A decline arrives, the coverage explains why this one is different, the discomfort becomes unbearable, and the portfolio is reduced near the bottom. Re-entry then waits for clarity, which by definition arrives after prices have recovered. The loss isn't the decline. It's the gap between selling and returning.
That's the single largest destroyer of long term outcomes we see, and it's entirely behavioral. Which is why we care more about whether you can hold a portfolio than whether it looks optimal, as covered in how to build a portfolio you can stick with.
Nothing here sits on its own.
A market decline isn't only a portfolio event. It changes what a conversion costs, what your losses are worth, whether a planned gift should be made this year, and how much you can comfortably spend.
Which is why the useful response to a bad market isn't a portfolio conversation. It's a plan conversation, and that only works if someone already holds the whole picture.
What we do instead of forecasting.
We don't predict markets, and we're skeptical of anyone claiming to do it usefully. What we do is build plans that don't require a forecast to work.
That means knowing what you actually spend and which part is committed, so a decline has a defined effect rather than an unknown one. It means holding a year of must-spend outside the market so no bad week forces a sale, which is the subject of how much do you actually spend. It means deciding in advance what a serious decline would cause you to change, in writing, while you're calm. And it means treating declines as scheduled events rather than surprises, because over thirty years they are.
When we do write about markets here, it will be to explain what something means for a plan, not to tell you what happens next.
If you'd like a plan that doesn't depend on anyone guessing right, let's talk.
Investing involves risk, including the possible loss of principal. Past performance is not a guarantee of future results, and nothing here is a forecast, a projection, or a recommendation for your circumstances.
Common questions.
- How do I tell whether market news matters to my plan?
- Three questions. Does it change what you need the money to do? Does it change the range of outcomes you were already planning for? Would you still think it mattered in five years? Almost nothing clears all three, and the small amount that does is worth acting on precisely because so little else is.
- What kind of news does warrant a change?
- Changes in your own circumstances far more often than changes in the market: your income, your health, your family, your spending, your goals. On the market side, a change in the rules rather than the mood, such as tax law or the structure of an account you rely on, is the category that genuinely reaches a plan.
- Isn't a large decline a reason to do something?
- A large decline is inside the assumption a plan is built on, not outside it. Markets fall substantially at unpredictable intervals because they always have. If a decline of that size breaks the plan, the problem was the plan's construction, and the useful time to fix that is before rather than during.
- Does the economy tell me what the market will do?
- No, and conflating the two is one of the most reliable ways to act badly. Markets price expectations rather than conditions, which is why they frequently rise on poor news and fall on good news. A confident economic forecast is not an investment edge even when the forecast turns out right.
- So what do you do instead of forecasting?
- We plan for a range rather than a prediction, decide the response to a decline before one arrives, and change portfolios when your circumstances change rather than when the news does. That is less satisfying to read than a forecast and considerably more useful to own.
