The S&P 500 has delivered a remarkable total return of 283% over the past decade, underscoring the stock market’s potential for wealth accumulation. Among standout performers, Amazon (AMZN) exemplifies how a company can thrive through diverse revenue streams, including retail, digital advertising, and cloud services. In Q4 2025 alone, Amazon’s retail operations generated $89 billion, while its cloud computing segment, AWS, boasted a 35% operating margin.

For investors, understanding the mechanics of a business, identifying its competitive advantages, and assessing valuation are crucial steps before making investment decisions. Amazon’s strong economic moat, characterized by network effects and cost advantages, enhances its market position, while its current price-to-earnings ratio of 28.9 suggests an attractive entry point.

Investors should leverage these three key questions to filter potential opportunities effectively, ensuring they make informed decisions that align with their financial goals.
