GameStop Stock Investment Post-mortem - Show Outline

The full show notes for this episode are available at https://www.diyinvesting.org/Episode30

Initial Buy Thesis Investment Results
  • Loss of 50-55% of the principal invested in GameStop stock
Investment Process
  • Was my Buy Thesis correct?
  • Root Cause of my Investment mistakes
  • Was my Sell Thesis correct?
  • I did not sell solely because the dividend was eliminated
  • Free cash flow from declining businesses ought to be distributed to shareholders
Conclusion
  • My bad process led to bad results in this case
  • Could have been better or worse
Lessons Learned Investment Rules
  1. Never buy a retail company with declining revenue
  2. Never buy a physical retail company with debt on its balance sheet (If they lease their locations)
  3. Do not hold onto a stock once you know your investment thesis is wrong
  4. Prioritize investing in companies where management has skin in the game
Red Flags
  1. A combination of large stock price declines without insider buying or stock buybacks
  2. Non-investors you talk to think the company will be a bad investment
