Leo Zwiener — Market Insights

One of my biggest early mistakes was thinking stock analysis meant reading charts and guessing price moves. The more I’ve learned, the more I see it’s about understanding businesses and long-term growth.

When I analyze a stock now, I usually start with the company itself before even looking at the chart. I want to understand what the company actually does, how it makes money, and why customers choose it. If I can’t explain the business model simply to someone, I probably shouldn’t be investing in it.

After that, I look at financials. Revenue growth is one of the first things I pay attention to because it shows whether the business is expanding. A few advanced things I also look at include profit margins, cash flow, debt levels, and earnings growth, to get a better understanding of the company’s financial strength. If the financials are weak, that becomes a major risk long-term.

Management is another huge factor that I think many investors overlook. Leadership decisions can completely change the direction of a company over time. I pay attention to CEO interviews, shareholder letters, earnings calls, and how management discusses long-term goals. This is a main reason I love the company JP Morgan so much, and it’s because of Jamie Dimon. Strong leadership can help companies survive, while poor leadership can destroy even strong businesses.

I also try to understand the company’s competitive advantage. Valuation matters too. Even an amazing company can become a bad investment if investors overpay for it. This is something I’m still learning because valuation is much more complex than just looking at a simple P/E ratio. Sometimes expensive stocks stay expensive for years because investors expect massive future growth.

Finally, I think it is very important to understand the risks of investing in a stock. Every investment has some risk, even if it is a company. I try to think about what could go wrong before I invest, not what could go right. This way of thinking has changed how I approach stock analysis. To be successful at investing, you need to understand how companies manage risk and be patient over time.
