Core Insights - The article emphasizes the importance of using checklists in investing, highlighting that not all checklists are equally effective. The DO-CONFIRM approach is preferred over the READ-DO approach for investment analysis [2][3]. Group 1: Understanding the Business - Investors should be able to explain a company's business model in simple terms, akin to explaining it to a 12-year-old. This understanding should precede any analysis of financial statements [4][5]. - The financial statements should align with the business narrative. Revenue is crucial as it is the lifeblood of any business, and discrepancies between management claims and revenue performance should be investigated [6][7]. Group 2: Financial Health and Growth - A strong business should finance its own growth through sufficient free cash flow, which indicates the ability to fund expansion without external assistance [8][9]. - The balance sheet's strength is vital for a company's agility and resilience. Excessive debt can hinder a company's ability to navigate challenges [10][11]. Group 3: Strategic Positioning and Risk Management - Companies with multiple avenues for growth, or optionality, are more attractive investments. This includes having assets that can support new business lines [12][13]. - Concentration risk can be hidden at various levels, such as reliance on a few customers or suppliers, which can pose significant threats to stability [14][15]. Group 4: Resilience and Adaptability - Companies that have demonstrated resilience during real-world challenges, such as the pandemic or economic shifts, are more likely to be robust investments [15][16]. - Acknowledging unknowns and potential risks is crucial for investors. Overconfidence can lead to overlooking vulnerabilities [17][18]. Group 5: Continuous Improvement - Investors should refine their checklists based on experiences, learning from both mistakes and successes. A disciplined approach is more beneficial than relying solely on intelligence [18][19].
