If you were to give me an update with less technical terms how you think it is going for you so far over all, I would be very interested to hear that 🙂

The attached graph shows the current stress test with losses beginning at /ES price of $6,363.29 (which appears to increase with volatility).

@Greggory Miller Wow! What is your background? If you would like to explain one of your positions to me in terms of what you think the value is and what the price is you have to pay for it, it would be very interesting to me. 🙂

@Greggory Miller I had missed that John Mihaljavec wrote a Manual of Ideas book as well. How you liked that one? Guy Spier's book was actually the first one I read about value investing in 2014 and that is how I discovered Mohnish Pabrai which later led me to invest directly in stocks in India in April of 2020. I had never seen such low valuations...funny how one thing leads to another. You are more than welcome to post in my community any time you like. Serve yourself! What a post by the way! I read it now and you just raised the standard in the community. I love it! 😎

My life changed when I discovered value investing over a decade ago. Still learning, improving and sharing the journey with others.
