Amazon vs. Walmart – A Revenue Shift
A fascinating chart from Charlie Bilello highlights the massive shift in market share between Amazon and Walmart over the last two decades. In 2010, Walmart had $100 billion in revenue, while Amazon was just one-tenth of its size at $10 billion. Fast forward to today, and Amazon stands at $187 billion, surpassing Walmart at $180 billion. This rapid transformation showcases how dominant players can be overtaken when innovation and adaptability drive growth.

The Risk of Stagnation
Established brands often enjoy investor confidence because of their historical success. However, they can also become complacent, losing market share to agile competitors. We see a similar story playing out in India, where companies like Asian Paints, once undisputed leaders, now face increasing competition from aggressive new entrants. Investors need to remain objective rather than blindly trusting past winners.
How Trend Analysis Can Help Investors
Investors who stuck with Walmart during its peak growth phase may have missed Amazon’s meteoric rise. However, those who monitored revenue momentum, market trends, and competitive positioning could have shifted their allocation as Amazon gained traction. If one were tracking trend strength in revenue growth, it would have become evident that Walmart’s momentum was slowing while Amazon was accelerating.
Momentum is the Key to Growth
Whether driven by liquidity, earnings, or market sentiment, momentum is what drives stock prices. Even a fundamental investor analyzing revenue momentum between these two companies would have eventually chosen Amazon. This reinforces the importance of staying flexible, watching trends, and reallocating capital towards businesses that are experiencing the strongest momentum.
The Takeaway for Investors
Markets evolve, and so should investment strategies. A once-dominant company can quickly lose ground if it fails to innovate. Investors who rely on momentum, whether in earnings, revenue, or price action, are better positioned to capture long-term gains. Identifying trend shifts early and adapting accordingly is the key to sustained success.
