Principles
Repeatable rules that beginners can study and adapt.
Applicable principles
Understand the business before buying the stock.
The growth story must be confirmed by numbers.
Classify stocks by growth, cyclicality, turnaround, or asset value.
Do not buy only because of rumors or attractive names.
Turn these principles into a pre-investment checklist. If an idea cannot pass the checklist, staying out is often better than forcing action.
