Second-Level Thinking

Deeper Explanation

Howard Marks defines second-level thinking as the cognitive process that separates investors who can generate alpha from those who can only hope to approximate market returns. First-level thinking produces the obvious answer: good company, buy the stock; bad economy, sell equities. Second-level thinking asks what the consensus already believes and how current prices compare to that belief. The key insight is that markets aggregate the views of many investors, all processing similar information. The consensus view is therefore already reflected in prices. For a security to outperform, an investor must hold a view that is both (a) different from the consensus and (b) correct. Holding the consensus view with confidence generates market returns at best — the expected return from holding what everyone else holds is the average return, not an above-average one. Second-level thinking is not contrarianism — it is not reflexively disagreeing with the consensus. It is the systematic comparison of one's own probability assessment with the market's implied probability assessment. When the market prices in a scenario the investor believes is too pessimistic, that divergence is the investment thesis. When the market prices in a scenario the investor believes is too optimistic, that divergence justifies avoiding the asset or shorting it. The practical challenge is developing genuine second-level thinking requires more than additional analysis. It requires developing views that are structurally different from the consensus — which often means doing different research, not just more of the same research. Analysts covering the same information with the same models will reach the same conclusions.
