Explanation

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

National Grid PLC had a gross margin of 22.84% for the quarter that ended in Sep. 2013 => Competition eroding margins


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.
