The Blood and Tears Lesson After Selling Amazon: Why I Am Now Holding Onto Medical Stocks Firmly

In 2014, I sold my Amazon stock because I hated the Fire Phone. I thought I was being smart, but then I watched Amazon rise 14 times, that sour feeling… The worst part is, I missed out not only on the stock price but also on Amazon's unbeatable innovation over the past decade.

What is the real lesson? Don't gamble on the founder's decisions with a short-term mindset. Amazon dared to fail, which led to gold mines like AWS, Whole Foods, and Prime. That's how founder-led companies work—sometimes new ideas seem foolish, but give them time, and they can turn things around.

Now I apply the same logic to TransMedics(TMDX). In 2023, they acquired an airline, and my first reaction was also, “What a terrible idea, the gross margin is doomed.” The stock price was halved directly. But this time I didn't sell—I chose to trust founder Waleed Hassanein.

Two years have passed, what are the results? The stock price has risen 3 times from its low point, and sales have doubled. The airline division that I thought was very stupid is now servicing 78% of organ transplants, with logistics revenue surging by 35%. The net profit margin has reached 17%.

Core Insight: The best investment is not to gamble on short-term fluctuations of stock prices, but to believe that ambitious founders can turn seemingly unreliable ideas into golden eggs. Wait, observe, and then bet again—this is much more reassuring than rushing to sell.
