Process Over Prediction: Five Lessons from Andy Constan
How to think clearly, weigh uncertainty, and focus on what actually moves markets
Our conversation with Andy Constan kept coming back to a familiar frustration. Investors are surrounded by smart people, strong opinions, and endless data, yet clarity often feels out of reach. What separates good decision making from noise is how information gets filtered, challenged, and applied.
Andy’s framework is built around that idea. It is less about having the right answer and more about building a process that avoids the wrong ones.
Here are the five lessons that stayed with us.
Lesson 1: The Most Valuable Skill Is Knowing What to Ignore
Andy opened with a straightforward point.
“The skillset that I value tremendously and really think that people need to pay attention to is critical thinking skills.”
In practice, that means aggressively filtering what you consume. He evaluates sources by asking whether they show their reasoning, whether they acknowledge uncertainty, and whether they are speaking within their circle of competence.
One of his clearest red flags is confidence without grounding. “There are a lot of people that have no basis for expertise who express that expertise with high confidence.” Those are the voices he tunes out quickly.
Even experience can mislead. Andy was blunt about how people misuse it. Experiential learning, he said, can become “a crutch” and in some cases “worse than no information at all” when investors assume the present must map neatly onto the past.
What he looks for instead are thinkers who combine experience with restraint. People who have seen cycles but still express uncertainty. Or, in his words, “people with experience who have low confidence in their views,” along with those who can reason through possibilities even without decades in the market.
Lesson 2: Good Process Beats Confident Forecasts
Andy does not approach markets by building a single narrative and assigning it a high probability. He works through possibilities.
When we discussed risk, he walked through how he frames the problem. There is a path where conditions deteriorate, another where they stabilize, and a range of outcomes in between. Each path unfolds on different time horizons, and each has different implications across assets.
Rather than forcing precision, he keeps those branches open and watches how markets respond. Oil, gold, bonds, volatility, and equities each provide clues about how investors are processing new information.
He is also skeptical of assigning neat probabilities to those outcomes. Point estimates like 30 percent versus 70 percent can create an illusion of accuracy that does not exist. Even market-implied probabilities, in his view, reflect positioning and sentiment, not objective truth.
That discipline shows up in how he updates his views. As he put it, outcomes often “go digital.” A Fed decision happens, a deal closes or falls apart, a policy shift is confirmed. When that occurs, the range of possibilities narrows and the process resets.
Mapping scenarios and adjusting as the range of outcomes changes leads to more durable decisions than committing early to a single story.
Lesson 3: Big Events Often Matter Less Than They Seem
Investors tend to anchor on major events and assume they will reshape markets in lasting ways. Andy’s instinct is to step back and ask what actually changes.
“I generally think the geopolitical change is something you wanna fade,” he said.
His reasoning is grounded in how limited the economic transmission often is. “Do the events in the Middle East have any impact on the US economy? The answer is not much.”
Part of the confusion comes from how history is used. It is common to see studies showing how markets behaved after past crises, but those comparisons often rely on small samples and overlook how different each episode is. Structural changes in policy, markets, and global linkages make simple analogies unreliable.
Andy is wary of drawing strong conclusions from that kind of data. Without enough observations, it is easy to mistake noise for signal.
A more useful lens is to focus on transmission channels. What changes for growth, earnings, credit, or capital flows? In many cases, the direct effects are modest even when the headlines are not.
Lesson 4: Growth Narratives Only Work If the Capital Shows Up
Across topics like AI investment, reshoring, and fiscal expansion, Andy kept returning to the same constraint.
“The promises that are made on AI spending, foreign direct investment in factories and government deficits require somebody to lend the money.”
It is an old idea expressed in a memorable way. He referenced the Wimpy line from Popeye, essentially “I’ll gladly pay you Tuesday for a hamburger today.” The economy can make big promises about future growth, but those promises depend on someone providing capital today.
“And those promises have massively increased,” he added.
That creates pressure in the system. Capital has to be raised, absorbed, and priced. When supply is large, costs can rise. When costs rise, some projects become less viable, and growth expectations have to adjust.
He pointed to examples in credit markets where large issuance has required wider spreads to clear, along with equity supply coming to market to help fund these investments. These are not abstract concerns. They directly affect returns and the durability of growth.
The key is connecting the narrative to the financing. It is easy to focus on the upside of technological change or policy support. It is harder to track who is funding it, at what price, and what happens if that funding becomes more expensive.
Lesson 5: Positioning and Global Flows Shape Outcomes
Andy spends less time debating what should happen and more time studying how capital is actually allocated.
Markets are influenced by positioning. If investors are already heavily tilted in one direction, even small changes can have outsized effects. That dynamic becomes more important when flows shift across regions.
He described a meaningful change in his own positioning. “I started lightening up in January and just have continued to lighten up until now I’m fully outta the US.”
That decision reflected a broader shift. For years, global portfolios were heavily concentrated in US assets. At the same time, developed markets outside the US began to offer more attractive bond yields, making balanced portfolios across regions viable again.
In that context, capital started to move. Currency flows, relative yields, and diversification needs all played a role. Andy’s move can be understood as part of that adjustment, stepping away from an extreme overweight and toward a more balanced global allocation over time.
Markets respond not just to new information, but to how that information interacts with existing allocations. Understanding that interaction provides a clearer lens than focusing on headlines alone.
The Bottom Line: Process is the Key to Handling Uncertainty
What stood out most from our discussion with Andy was a consistent way of approaching markets: filter aggressively, map possibilities rather than forcing precision, and stay anchored to the mechanics of capital and positioning.
He is wary of overconfidence, whether it comes from experience, data mining, or clean narratives. He prefers frameworks that can adapt as new information arrives and that recognize how quickly conditions can change when outcomes become certain.
That orientation does not eliminate mistakes. It reduces the odds of making avoidable ones, especially those driven by noise, misplaced certainty, or incomplete thinking. Over time, that discipline compounds with far more consistency.
