With information now ubiquitous, the primary source of market inefficiency is no longer informational but behavioral. The most durable edge is "time arbitrage"—exploiting the market's obsession with short-term results by focusing on a business's normalized potential over a two-to-four-year horizon.

Marks frames contrarian investing not as simple opposition, but as using the market's excessive force (optimism or pessimism) against itself. This mental model involves letting the market's momentum create opportunities, like selling into euphoric buying, rather than just betting against the crowd.

Identifying a stock trading below its intrinsic value is only the first step. To avoid "value traps" (stocks that stay cheap forever), investors must also identify a specific catalyst that will unlock its value over a reasonable timeframe, typically 2-4 years.

Traditional valuation metrics ignore the most critical drivers of success: leadership, brand, and culture. These unquantifiable assets are not on the balance sheet, causing the best companies to appear perpetually overvalued to conventional analysts. This perceived mispricing creates the investment opportunity.

Camillo's 'social arbitrage' strategy focuses on identifying meaningful, off-radar changes in the world (e.g., consumer trends, cultural shifts). The goal is to invest at the point of information asymmetry and exit when the information becomes widely known, ignoring traditional financial metrics.

Wagner's strategy shifted from buying statistically cheap companies to requiring a clear catalyst for value realization. He found that without a catalyst, even correctly underwritten cheap stocks would continue to decline due to factors like technological disruption, making the old "cigar butt" approach obsolete.

A specific arbitrage opportunity exists with serial acquirers. When they announce a deal that will significantly increase future earnings per share, the market often under-reacts. An investor can buy shares at a compressed forward multiple before the full impact of the acquisition is priced in.

Companies like Tesla and Oracle achieve massive valuations not through profits, but by capturing the dominant market story, such as becoming an "AI company." Investors should analyze a company's ability to create and own the next compelling narrative.

This provides a simple but powerful framework for venture investing. For companies in markets with demonstrably huge TAMs (e.g., AI coding), valuation is secondary to backing the winner. For markets with a more uncertain or constrained TAM (e.g., vertical SaaS), traditional valuation discipline and entry price matter significantly.
