End of August 2021 Summary of Summaries:
I have found the end of month summaries from the board heavyweights to be an invaluable resource and have enjoyed seeing the wisdom from Saul’s Knowledgebase constantly applied (lessons learned and/or re-learned). The summaries show the value of crowd-sourcing ideas but also independent thought. I catalog the summaries each month and have found the data I’ve gleaned to be very helpful in analyzing my portfolio and forming my own convictions. Hopefully, some will find this data helpful. It is meant to ask questions like:
- Why do I own a stock that no one else owns (opportunity cost)?
- Why do I have 40% of my portfolio in a stock when no one else does (should I trim my position)?
- Why do I own so many or so few stocks (portfolio concentration)?
- Why don’t I own a stock that is heavily owned by the group (did I miss an important thread)?
- Members of the group have started buying a new stock. Should I start a position?
End of August 2021 Summaries:
Thanks to all the end of the month contributors below for the time you spend and the detail you provide. We all benefit from your efforts. A special thank you to Saul for his wisdom and life-changing guidance. If this thread is not deemed off-topic and proves helpful, I will try to publish a summary of summaries every month.
