Cadrivolna — Understanding and using scenario analysis
Structured resources to help you build stronger investment research habits, understand key analytical frameworks, and approach your own decision-making with greater confidence.
Getting started with structured research
If you are new to approaching your investments in a structured way, the most important first step is defining what you are actually trying to find out. Many investors begin their research by gathering information before they have a clear question, which means they often end up with a lot of material but no coherent view. A well-formed research question acts as a filter: it tells you which information is relevant and which is background noise.
Start by writing down the specific question your research is meant to answer. It might be whether a company's competitive position is as strong as its recent results suggest, or whether a sector's current valuation reflects a genuine change in fundamentals or simply a shift in sentiment. Once the question is clear, you can build a research structure around it rather than assembling facts and hoping a conclusion emerges.
Understanding and using scenario analysis
Scenario analysis is one of the most practical tools available to a private investor, and one of the most frequently misused. The purpose of building scenarios is not to predict which outcome will occur — it is to understand the range of plausible outcomes and what each one would mean for your investment thesis. A good set of scenarios should genuinely challenge your base case, not simply restate it with slightly different numbers.
When building scenarios, focus on the key variables that your thesis depends on most. For a company, that might be the trajectory of its core market, the sustainability of its margins, or the credibility of its management guidance. For each variable, define what a more optimistic and a more cautious version would look like, and then ask yourself what conditions would need to be true for each version to materialise. The discipline of answering that question honestly is where the real value of scenario analysis lies.
Examining assumptions in your own reasoning
Every investment view rests on assumptions, and the most consequential ones are often the ones you have not consciously acknowledged. When you find yourself feeling confident about a particular holding or opportunity, it is worth pausing to ask: what would need to be true for this view to be correct? Write those conditions down. You may find that some of them are well-supported by evidence, while others are simply things you have assumed because they feel plausible.
Surfacing hidden assumptions does not mean abandoning your view. It means understanding it more precisely. An assumption that is well-grounded in evidence is a foundation; an assumption that you have not examined is a risk. The habit of making your assumptions explicit before you act on a view is one of the most reliable ways to improve the quality of your research over time.
Building a personal research process
A research process does not need to be elaborate to be effective. What it needs is consistency: a set of steps you follow each time you examine an investment question, so that your analysis is thorough rather than dependent on whatever happens to occur to you on a given day. A simple process might involve defining the question, gathering relevant information, building scenarios, identifying key assumptions, and reviewing the risks before reaching a conclusion.
The value of a consistent process compounds over time. Each time you follow it, you are not only producing a better-informed view on the current question — you are also building the habit of structured thinking that will serve you on every future question. The goal is not to eliminate uncertainty, which is impossible, but to ensure that the decisions you make are based on the best reasoning you are capable of, applied consistently.
