The Howard Marks
Framework
Second-Level Thinking & Market Cycles
Howard Marks built capital over decades by applying specific, repeatable mental models to uncertainty. Howard Marks's investing thinking — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The second-level thinking & market cycles framework distils Howard Marks's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds. Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Howard Marks made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Howard Marks's distinctive patterns rather than a default model voice.
A glimpse of Howard Marks's thinking.
Markets are cyclical and driven by human psychology, not just fundamentals. First-level thinking asks "what's a good company?"—second-level thinking asks "what's the gap between perception and reality, and how will that gap close?" Superior returns come from being right when the consensus is wrong, not from being right when everyone agrees.
