One Up on Wall Street: How to Use What You Already Know to Make Money in the Market
In One Up on Wall Street, legendary investor and former manager of the Fidelity Magellan Fund Peter Lynch describes a no-nonsense approach to the stock market. Rather than following the complex predictions of so-called professionals or leaping on the latest and greatest overpriced stock, he advises you to keep your own counsel, be self-reliant, and see yourself as your greatest resource.
The following One Up on Wall Street quotes highlight some of the key pieces of Lynch’s investing advice:
“By putting your stocks into categories you’ll have a better idea of what to expect from them.”
How you invest in a stock depends on what type of stock it is, and it’s important to understand the type before you invest. This ensures you have correct expectations of that company’s performance and won’t sell a stock in a company type prematurely. Lynch divides all stocks into six categories:
Slow-growth companies: Most companies that start out as fast growers eventually become slow growers. Lynch doesn’t particularly recommend investing in slow-growth companies because you won’t make money fast.
Dependable companies: These are large, established companies that grow more quickly than slow-growth companies but still maintain a relatively slow pace. It’s good to have a few dependables in your portfolio because they’ll keep you afloat in market downswings since they generally aren’t as strongly impacted by such swings as smaller companies are.
Fast-growth companies: These companies are small and grow aggressively, at 20 to 25% per year. Such companies also tend to be tenbaggers or higher. These companies are riskier than dependable companies.
Cycle companies: These are companies that grow and contract in cycles. Such companies can be dangerous for inexperienced investors if they don’t understand when’s the best time to invest and that a downswing will be followed by an upswing.
