RESEARCHOpen ThesisMemo Replace the slogan with a business claim
“AI will grow” describes a theme, not a complete thesis about a particular company. A more useful claim identifies the customer, the product, the economic benefit and a time horizon. For example: a hypothetical software company may improve profitability if existing customers adopt an additional module without a similar increase in selling costs. This is a proposed mechanism, not a forecast disguised as a fact.
Choose evidence before the next headline
For that hypothetical company, select a few indicators: module adoption, customer retention and sales expense relative to revenue. Define where each number will come from. If the company does not disclose adoption, acknowledge the gap instead of substituting an unrelated metric. Separate published observations from your own interpretation in the worksheet. Official filings are a starting point for financial evidence, not an endorsement of your thesis.
Write the disconfirming case
Imagine that adoption rises but customer discounts deepen and profitability deteriorates. That combination would challenge the original mechanism. Before the next report, state what evidence would lead you to reduce confidence. Avoid automatically rewriting the thesis whenever a disappointing result arrives. Conversely, one noisy quarter need not invalidate a multi-year claim: explain why the chosen evidence is or is not decisive.
Keep a dated decision journal
Use five fields: claim, supporting evidence, competing explanation, valuation assumptions and next review date. Record what changed at each review. A hypothetical tenfold increase in operating profit expectations does not establish an attractive investment if the purchase price already assumes more. Business quality, price paid and portfolio suitability are separate questions. A testable thesis helps organize uncertainty; it does not eliminate it.
