Munger said "invert, always invert." So I made a list of things that reliably destroy value - and started screening for their absence

AI Summary
Summary
The post advocates for an "inversion" approach to stock screening, inspired by Charlie Munger. Instead of looking for positive attributes, the author filters for the absence of common value-destroying characteristics.
The author's thesis is that screening out companies with negative traits (e.g., serial dilutive acquirers, debt-funded buybacks at peaks) is a more efficient way to find quality investments than screening for positive traits.
Quality assessment: This is a conceptual post about investment philosophy and screening methodology, not deep-dive due diligence (DD) on a specific company. It's a high-level strategic discussion.

Instead of looking for companies with great management, I started screening for companies without:
\-Serial acquirers who dilute on every deal
\-Founder departures followed by consultant-CEO appointments
Investor day "targets" that get quietly reset every 3 years
\-Capex-heavy businesses in industries with no pricing power
\-Share buybacks funded by debt at peak multiples
What I found: filtering out destroyers of capital is actually a faster filter than scoring positives. Out of 3,000 stocks I track, only \~180 pass this negative screen
What would you add to the "anti-checklist"?
