Warren Buffett believes that firms with excellent long term economics tend to have consistently higher margins.
Durable competitive advantage creates a high Gross Margin % because of the freedom to price in excess of cost. Companies can be categorized by their Gross Margin %
1. Greater than 40% = Durable competitive advantage
2. Less than 40% = Competition eroding margins
3. Less than 20% = no sustainable competitive advantage
Consistency of Gross Margin is key
Formosa Electronic Industries had a gross margin of -31.67% for the quarter that ended in Dec. 2025 => No sustainable competitive advantage
Be Aware
If a company loses its competitive advantages, usually its gross margin declines well before its sales declines. Watching Gross Margin % and Operating Margin % closely helps avoid value trap situations.
