“The Buy Forever Secret: 8 Stocks Built to Last 50+ Years”

Many companies that were once considered great eventually faded into irrelevance. That leaves investors asking:

What makes a company a true “forever” stock?

The answer: a sustainable competitive advantage—also known as an economic moat.

The 5 Types of Competitive Advantages

1. Network Effects – The more people use it, the stronger it gets (e.g., payments, social platforms).
2. Switching Costs – Customers can’t leave easily without significant expense or disruption.
3. Cost Advantages – Scale and efficiency that competitors can’t replicate.
4. Intangible Assets & Patents – Legal and brand protections that drive pricing power.
5. Efficient Scale – Industries where duplication is uneconomical or impossible.

But here’s the real secret:

These moats don’t just exist in theory—they show up in the fundamentals.

• Return on Invested Capital (ROIC): Elite companies reinvest capital at high rates of return (10%+ solid, 20%+ exceptional).
• Gross Profit Ratio: Companies that maintain or expand margins over time are usually defending a moat.

A strong moat protects both profitability and the ability to compound returns over decades.
