Many people treat uncertainty as something they should eliminate before they can get on with things. In investing, that instinct can cause significant damage. Ironically, investing works because markets are unpredictable.
If markets were predictable, just about every asset would carry the same return, the risk-free rate, and nothing more. Stocks pay more than bonds over time precisely because nobody can promise you they will, not even the government or the fund manager who has been beating the market for a decade. If that risk disappears, so does the reward.
David Booth, who worked for 45 years building Dimensional Fund Advisors around this idea, puts it this way: uncertainty is not something to eliminate from your investing life. It’s something to manage.
So much of investing anxiety comes from treating an unpredictable process as if it should behave predictably. You didn’t know twenty years ago where you would be today, and you will not know twenty years from now either. That doesn’t stop you from planning a life, and it shouldn’t stop you from planning a portfolio.
Even Professional Investors Struggle to Beat the Market
The people who are paid the most to beat the market typically don’t, especially once you account for fees. With fees in the picture, the average professional manager underperforms a simple, low-cost index over long stretches of time.
This is no knock on their intelligence, work ethic, or skill. It’s simply a function of how markets work. Prices move because sophisticated buyers and sellers are constantly competing to find mispricings, and that competition is what makes mispricings rare and short-lived.
So their effort is worthless? No, not necessarily.
It’s that the kind of effort that works, including deep research, broad diversification, and patient structuring, looks nothing like the kind of effort that gets attention: bold calls, hot picks, and timed exits. The boring version wins more frequently, over more decades, for more individuals. It just doesn’t make for a good headline, which is part of why so few people ever hear about it.
Learn to Separate Useful Investment Information From Market Noise
There’s more financial data available to the average person today than any professional had access to a generation ago. Phones deliver a constant stream of prices, forecasts, and hot takes before breakfast. In many ways, it’s an unhealthy overload of information for many people. It’s simply too much, and almost none of it is meaningful information that informs any kind of decision.
A piece of information is meaningful if it should change what you do with your portfolio. A change in your income, your family situation, your time horizon, your tolerance for risk, these are meaningful. An opinion about next quarter's inflation number or a prediction about where interest rates go from here, these are almost always just interesting. They make for a good conversation, but they rarely make good reasons to touch your portfolio.
The discipline worth building into your approach is not about reading less or tuning out day-to-day price moves. It is about asking, every time something crosses your desk, whether it actually changes what you should do. If the answer is no, file it under interesting and move along. Most things belong there, and learning to sort them quickly is a valuable skill.
Plan, Don't Predict
A phrase that captures this philosophy is “Plan, don't predict.” It sounds simple because it is, but simple is not the same as easy, as the great Charlie Munger said repeatedly of his own investing strategy that made him one of the wealthiest people in the world.
Predicting is seductive, and it offers the feeling of control. Planning offers something less exciting and more durable, a process you can trust even when you have no clue what happens next. A prediction is a bet on a single outcome. A plan is a structure made to survive a wide range of outcomes, including the ones you can't see coming.
Flexibility Matters in a Long-Term Investment Strategy
Flexibility has economic value when it comes to investing. Rigid plans break when circumstances change. Plans made with some give in them, room to update assumptions as new evidence arrives without abandoning the underlying approach, tend to hold up better over long periods.
So being willing to challenge your own conclusions, even ones that have served you well for years, is not a weakness in a strategy. It’s what keeps a strategy alive long enough to matter as conditions change around it… because they inevitably will.
Long-Term Investors Have Reason to Be Optimistic
Optimism in investing does not mean assuming everything will work out. It means looking at the long history of markets and recognizing that economies have repeatedly recovered from recessions, wars, financial crises, and other major disruptions.
That history does not tell investors what will happen next, but it does offer a useful perspective. Markets will go through difficult periods, and some of them will be severe. Yet over long stretches of time, businesses adapt, economies recover, and growth eventually resumes.
The practical lesson is to focus on the things you can control. That includes how much risk you take, how diversified you are, how long you stay invested, and whether your portfolio is built to withstand difficult periods. Build a plan that does not need every outcome to go your way.
