What’s the recipe for disciplined investing?

By Will Hubbard

Every Saturday morning, I make baked French toast for my family. My daughters love it, and it has become our regular weekend treat. Lately, making it has me thinking about the difference between a good result and a repeatable process.

Since the French toast has to be assembled the night before, I usually start making it on Friday evening. I like rules and processes, so I naturally began by following a recipe. But over time, especially on hectic Friday nights with my 2-, 4-, and 6-year-olds, I have become more flexible.

I follow the general idea, but I adjust by feel. I keep adding ingredients until my brain says, “That’s fine.” I may substitute something because we’re out of it, or because I can’t easily find it and don’t feel like looking. At that point, my main goal is to get to bed, because if my kids are sleeping, I want to be too.

Most weeks, it works out fine. As long as I stay close to the original recipe, everyone is happy.

This past Saturday, though, I had to improvise more than usual because we were missing a few ingredients. I eyeballed the measurements, made a few substitutions, and added what seemed to make sense at the time. When it came out of the oven the next morning, everyone agreed it was one of the best versions I had made.

That was great to hear. The problem was, I had very little idea what I had actually done.

Investing can work a lot like that.

A good result is not the whole story

No one’s knocking a good outcome. It’s great when the market goes up and takes your portfolio with it. And in my case, the French toast turned out great, the reaction was even better, and no one was disappointed by a successful Saturday morning breakfast.

But if I want to make that same version every Saturday, the result alone is not enough. I need to understand what produced it.

Was it how long the apple cider vinegar sat in the almond milk? The type of bread? The cinnamon? The coconut sugar mixed in and sprinkled on top? Or is the usual light brown sugar actually better? Did a missing ingredient improve the texture, or did the recipe turn out well despite its absence?

Investors should ask a similar question: Was the result good because the process was sound, or was it because we got lucky?

A portfolio can produce a strong return over a short period, such as a quarter, and still leave that question unanswered. Stocks can rally because earnings are improving. They can also rise because interest rates fall, sentiment improves, liquidity expands, short positions unwind, or investors choose to look past an as-yet unresolved risk.

The return number may look the same, but what produced it can be very different.

That does not mean investors should dismiss every rally or assume every favorable outcome is fragile. Results matter, but so does the explanation behind them. When a strategy performs well, investors should want to understand why. When it struggles, they should want to know whether the weakness is temporary, consistent with how the strategy is designed to behave, or a sign that something has changed.

Separating luck from skill

When something goes well, we often want to credit skill: “My French toast was good. I must be a great chef.”

When something goes poorly, we may be just as quick to blame bad luck: “We didn’t have the right sugar, so the topping didn’t have that tasty crunch.”

The same tendency shows up in investing. A strong return can make a decision or strategy look smarter than it was, while a disappointing return can make a sound process seem flawed.

Disciplined investors have to resist both conclusions.

One good result does not prove the process was right, just as one poor result does not prove it was wrong. The more useful question is whether the outcome is consistent with a repeatable, understandable process—and with the conditions in which that process was designed to operate.

Why a disciplined process matters

That is one reason a quantitative, risk-managed investment process can be valuable.

Rather than relying on a single decision, forecast, or interpretation of the current environment, a thoughtful quantitative process can test ideas across many observations and market conditions. It allows investment managers to test signals and assumptions, study how they have behaved over time, and better understand what has historically driven performance. This repeatable, evidence-based approach is central to Flexible Plan Investments’ (FPI’s) investment philosophy.

The goal is not to create certainty. That is impossible.

A disciplined process can, however, provide a more consistent basis for evaluating results. It can help identify the environments in which a strategy has tended to work, where it may struggle, and whether current results are consistent with what it was designed to do.

Dynamic risk management adds another important element: the ability to respond as market conditions change. A process can be disciplined and repeatable without being rigid. As risks, trends, and market relationships shift, FPI’s strategies can adjust according to their established rules rather than relying on an emotional reaction or an improvised decision.

Repeatable does not mean predictable

I can follow the same French toast recipe week after week, and the results may still vary. The oven may run hotter. The bread may absorb more liquid. Even the humidity in the house can affect how it turns out.

Investing is no different. No process will work perfectly in every market environment. But without a disciplined framework, investors can be left reacting to each new outcome and making emotional decisions based on whatever the market is doing at the moment.

I am glad the French toast turned out well. But if my daughters ask for that exact version again, then I’m in trouble.

Investing should not operate that way.

A good outcome is always welcome, but one result tells us only so much. A disciplined, repeatable process provides a clearer way to understand what produced that result and whether it was consistent with how the strategy was designed to behave. That is how FPI approaches investing.

Investing should not be about chasing the latest return or the hottest market index. It should be about understanding the process behind the result, evaluating whether that process remains effective, and staying humble enough to recognize when it may need to evolve.

Right now, the market may be serving investors a version of French toast they like. The harder question is whether anyone actually knows the recipe.
