Free Cash Flow does not equal Net Income Profit is an opinion, cash (flow) is a fact. Many investors confuse Free Cash Flow with Net Income. Knowing the difference between these two is crucial. 2. Podcast interview Recently I was a guest in the Stansberry Research Podcast. We discussed the following: AI and market momentum A company I'm excited about right now And much more Happy listening! 3. One simple investment quote Your investment portfolio is like a bar of soap. The more you touch it, the smaller it gets. That's why doing nothing is often your best bet. Time in the market always beats timing the market. 4. Warren Buffett: A Life and Legacy A must watch this week? The documentary 'Warren Buffett - A Life and Legacy'. It's full of wisdom. Both for life as investing. 5. Stock Pitch: Markel ($MKL) How does the company make money? Markel makes money by selling specialty insurance. It collects premiums first and, over time, pays out less in claims than it takes in to generate a profit. The premiums it holds before paying claims ("float") are then invested in stocks, bonds, and private businesses to make more money. Markel ($MKL) is often called a mini-Berkshire Hathaway. It specializes in niche insurance markets the company prices risks better than competitors. But Markel doesn't stop at insurance. It reinvests its float into a high-quality investment portfolio and wholly owned businesses. This combination of insurance and investing is what makes Markel very powerful. It's built to compound over the long run. Bron: Markel Everything in life compounds Pieter (Compounding Quality) PS You are not a Partner of Compounding Quality yet?
