This checklist is based on mistakes great investors such as Warren Buffett, Seth Klarman, Peter Lynch, and many more have made. The checklist focuses on four key elements:

1. Industry and business 2. Management 3. Financials 4. Risk factors

You don’t need to invest in any specific company. Your goal is to maximize the odds in your favor so that the potential upside is multiples bigger than the downside.

Always remember that if you lose 50% you will now need to earn 100% just to get back to what you already had.

The full checklist can be downloaded in a pdf format from here.
