    Terry Smith - Fundsmith Postmortem (opens the original)

    Excerpt

    Read excerpt

    This is a continuation of a series looking at some high profile value investors that have seen their funds underperform their benchmarks over the past decade and a half. I’ve previously looked at David Einhorn’s fund and connected some interesting dots regarding his performance and his struggles relative to the S&P 500. Below is a quick recap. It’ll be interesting to see if there are any common themes as I further explore the space. David Einhorn Lessons:High churn and early exits left a lot of

    Going Nuclear (opens the original)

    Excerpt · Critical tone

    Read excerpt

    I wasn’t always like this. I very much identify as a value investing ‘purist’. I love low price-to-earnings stocks as much as the next guy, and I would love to write about “solid businesses at great prices”. In March of 2020, I was buying General Dynamics and other defense names at single digit PEs. In 2021, I bought pharma names under 15x. In 2024, I wrote about the relative attractiveness of developed international stocks compared to U.S. indices. But that’s not the market of today. Most of th

    Vertical Aerospace’s blunders offer up an interesting case study in management decision making and pre-revenue valuation dynamics. <img alt="" class="sizing-normal" height="1216" src="https://substackcdn.com/image/fetch/$s_!922q!,w_1456,c_limit,f_auto,q_auto:g
