In a world of highly skilled money managers, absolute skill becomes table stakes and luck plays a larger role in outcomes. According to Michael Mauboussin's "paradox of skill," an allocator's job is to identify managers whose *relative* skill—a specific, durable edge—still dominates results.

The world's top investors have a median hit rate of only 49%, meaning they lose money on the majority of their investments. Their outperformance comes from making significantly more on their winners than they lose on their losers, a concept known as payoff ratio.

Top tennis players like Rafael Nadal win only ~55% of total points but triumph by winning the *important* ones. This analogy illustrates that successful investing isn't about being right every time. It's about consistently tilting small odds in your favor across many bets, like a casino, to ensure long-term success.

A study in the book "Art of Execution" found the world's best investors have a win rate equivalent to a coin flip on their top 10 ideas. This proves superior returns come from how positions are managed after the initial buy decision, not from superior stock picking alone.

Successful investing isn't about being right all the time; it's about making your wins exponentially larger than your losses. Top investors like Paul Tudor Jones only enter trades where the potential reward is at least five times the risk, allowing them to be wrong often and still profit.

By reverse-engineering a manager's portfolio weights to infer their expected returns for each stock, research identifies their "best ideas." These high-conviction positions outperform the other stocks held by the same manager by approximately 4% per year, showing that managers can identify their own winners.

Over 58 years, Warren Buffett made ~400 investment decisions, but only 12 truly mattered—a 4% hit rate. The crucial insight is not just buying right, but holding these few exceptional businesses for decades, allowing compounding to work its magic.

Analysis of New Zealand Super's performance revealed a mediocre "batting average" (hit rate of successful investments) but an amazing "slugging average." They succeeded by allocating disproportionately large amounts of risk to their highest-conviction ideas. The magnitude of wins, not their frequency, drives long-term outperformance.

Even for the world's greatest investor, success is a game of outliers. Buffett made the vast majority of his returns on just 10 of 500 stocks. If you remove the top five deals from Berkshire's history, its returns fall to merely average, highlighting the power law effect in investing.
