I have a question about habit number 2, Add up, don’t double down. If I buy more of a volatile stock after it has risen significantly, but then buy more when the price drops, am I still following the rule? Thanks for your insight, Jason Corso. Jason Corso, the Toyota professor of AI at the University of Michigan, recently read Rule Breaker Investing by David Gardner and has questions about habit number 2, “add up, don’t double down.” Gardner advises to add to investments that are going up rather than persistently going down to avoid going poor in the stock market.

Gardner emphasizes the importance of adding to investments that are already going up, especially in Rule Breaker stocks. He encourages investors to focus on the business behind the stock rather than its recent performance, looking for traits that align with Rule Breakers principles.

In response to Corso’s question, Gardner plans to update his Rule Breaker Investing book with a bonus chapter that addresses FAQs and provides additional guidance on investing habits. He emphasizes the need to cultivate the habit of adding to investments that are on an upward trajectory to avoid common pitfalls in the stock market. Summary 1: When deciding whether to add to an existing stock position, focus on companies that are performing well and showing traits of a Rule Breaker. Avoid adding to stocks that are losing their competitive advantage, facing disruptive technology, or experiencing declining brand reputation.

Summary 2: A reader named Dave shares his investment journey and success following Rule Breakers principles. He stays 100% invested in the stock market, believing in its long-term growth. Dave credits his wealth generation to mentors like Peter Lynch and Warren Buffett and plans to continue investing in his 70s, 80s, and 90s.

Summary 3: Dave’s approach challenges conventional wisdom of gradually shifting wealth from stocks to bonds as you age. He remains optimistic about the future, emphasizing health span over lifespan. Dave’s story reflects the mindset of a Foolish investor, focused on maximizing wealth generation and remaining active in society and community. Dave, you mentioned the importance of knowing your “sleep number” in investing, or the percentage of your portfolio you’re comfortable having in your largest holding. This is crucial for managing risk and ensuring you’re not overexposed. It’s a key strategy to consider when building a diversified portfolio.

Mark Minor shared his experience of having a 97-bagger in Netflix, even after a 10% drop that exceeded his initial investment. He coined the term “spiffy-drop” for such occurrences when a stock loses more in a day than your initial investment. These spiffy-drops can happen with high-growth stocks and are part of the investment journey.

Maria from Rotterdam asked David about his approach to cyclical industries and evaluating past price appreciation in companies. David explained that cyclical industries are tied to economic cycles and may not be durably profitable. Rule Breakers focus on companies that create their own demand and innovate. Evaluating strong past price appreciation involves looking at both short-term and long-term performance to assess a company’s trajectory accurately. The growth of disruptors like Rule Breakers comes from innovation and customer satisfaction, not economic cycles. These companies continue to perform well even in market downturns. Rule Breakers create their own industry classification, showing they are leaders, not followers. Past price appreciation indicates momentum and excellence, not just short-term volatility. Understanding the underlying story of a company is key to investing in Rule Breakers. Leaving online reviews for books like Rule Breaker Investing can help spread the message of long-term investing and buying excellence.
