According to @QCompounding, Philip Fisher used a 15-point checklist to find outstanding companies rather than follow stock tips, underscoring a repeatable quality-growth process relevant to modern stock selection (source: @QCompounding). To operationalize Fisher’s checklist in trading, screen for 3–5 year revenue CAGR above industry for market potential, rising operating margins and expanding gross margins for superior profitability, R&D-to-sales in the top quartile for strong research capability, consistent sales growth with low customer concentration for a capable sales organization, cash from operations closely tracking net income for conservative accounting, stable or declining share count and meaningful insider ownership for management quality, and manageable leverage with reinvestment discipline for sustained growth (source: Philip A. Fisher, Common Stocks and Uncommon Profits). These Fisher-aligned indicators can be embedded into pre-earnings quality-growth screens and post-earnings follow-through filters to focus on durable competitive advantages and scalable margins when timing entries and managing risk in growth-focused portfolios (source: Philip A.
