Good start focusing on companies you understand. I like that you're looking at the 3, 5, and 10-year graphs. That said, don't rely solely on past performance. Dig deeper! What's the story behind these numbers? What are the company's competitive advantages? Visit their stores, use their products. Get a feel for the business. Also, don't be afraid to look at smaller, less-known companies. That's where you often find the best opportunities.
