Weighing Risk & Reward: The Intersection Where Art Meets Science

In poker there is a saying: "play the player, not the cards." The game is a mixture of art, science, and luck. Underlying this psychology is a statistical concept called pot odds—the ratio of the current pot size to the cost of a contemplated call. Mastering the science along with the psychological art of the game fundamentally improves the chances of success and minimizes the role luck plays.

The same is true of investing.

The Market's Upward Bias

The market is biased to go higher and, despite periods of volatility, has done just that over the past 150+ years. Since 1871, the market has been positive 63.7% of the time over the next twelve months across 1,820 monthly periods. When looking at the tails of this distribution, positive outliers outweigh negative outliers: there are 95 observations (5.2% of the time) where the market rose 35% or more in the proceeding twelve months, versus 34 observations (1.9%) where it fell 35% or more.

We term this ratio "severity odds"—the ratio of positive severity over negative severity. At roughly 3 to 1 odds, this upward bias provides a meaningful foundation for investing. But the real question is: where are the best hunting grounds within the market itself?

Where the Odds Are Best

When we apply this framework to the small cap space and analyze relative returns to the Russell 2000 Value Index over the past 20+ years, the findings are clear. Roughly 47% of stocks outpace the index over any next twelve-month period, with severity odds of 1.1.

Breaking this down by sector reveals significant dispersion. Pharma/Biotech, Regional Banks/Thrifts, and Communication Services provide the lowest hit rates and poorest severity odds. Utilities and REITs are the only two sectors where you have a slight edge—above 50% chance of beating the index. But even there, the reward profile is constrained.

The more important finding is what happens when you apply a value, momentum, and quality (VMQ) filter to these groups. Our process improves the hit rate by roughly 500 basis points—making it better than a 52% chance of outperforming the index—and provides better severity odds of 2.3 versus 1.1 for the entire universe. The risk profile improves for virtually all sectors. Regional Banks and Financials exhibit a better reward profile with less required risk. Pharma/Biotech exhibits the largest improvement in risk with minimal loss in reward.

When the Odds Are Highest

The evolution of these ratios over time reveals another key pattern: the highest probability of success occurs when fear gauges are at extremes. Periods of heightened fear—VIX exceeding 40% and high-yield spreads beyond 7%, like the 2008/2009 credit crisis and the 2020 COVID pandemic—have yielded the most pronounced positive severity outcomes.

This is episodic investing. The market provides pockets of opportunity, and it is in those pockets that the value factor will provide the highest probability of picking winners.

The Summation

Luck in the markets as in poker eventually runs out. But a strategy rooted in a proven process, combined with discipline and experience, increases the odds of success over market cycles. As the movie Rounders put it: "Why do you think the same five guys make it to the final table of the World Series of Poker every year? What, are they the luckiest guys in Las Vegas?"

They are not. And neither are the investors who consistently outperform.
