What Blackjack Taught Me About Investing
As many clients know, for about a decade I moonlighted as a professional blackjack card counter, which was outlined in my book, The Blackjack Life (Huntington Press, Las Vegas, 2012). To some it may seem like a gambling endeavor, but if you’ve read my book, you’ll know that many of the principles that led to long-term success in the casinos are the same ones that apply to managing wealth thoughtfully. The game of blackjack, when approached professionally, with skill, and with math, is not about luck. It’s about discipline, probabilities, and making consistently sound decisions over time. And that translates remarkably well to investing.
It’s Not About Winning Every Hand
One of the first lessons you learn in blackjack is that you’re going to lose… a lot. Even when you play “perfectly.” You can make the mathematically correct decision and still get a bad outcome in the short term. That’s simply part of the game. And investing works the same way. There will be periods where markets decline or decisions with outcomes that aren’t favorable. But that doesn’t make them wrong decisions. The goal isn’t to win every hand. It’s to play each hand correctly, time and time again, and let the probabilities work over time.
Discipline Matters More Than Intelligence
Blackjack is a simple game to understand, but a difficult one to execute consistently. The challenge isn’t knowing what to do, but having the discipline to do it, especially when emotions get so easily get involved. After a losing streak, the temptation is to deviate from sound principals. The temptation is to press and to chase, which is where mistakes happen. With investing, the same dynamic shows up during periods of volatility or, in the words of former Federal Reserve Chairman, Alan Greenspan, “irrational exuberance.” The hardest moments are often when discipline matters most and when staying the course feels uncomfortable. The clients of ours who are most successful over time aren’t the ones who ask us to outsmart the market. They’re the ones who remain disciplined when it matters.
You Can Only Control Decisions
At the blackjack table, once the cards are dealt, the outcome is out of your control. All you can control is the bet sizing and playing decisions you make, based on the information available (the rules, the count, the number of decks remaining to be played). That’s it. In investing, we can’t control the markets, interest rates, or headlines, but we can control how we respond to them. Consequently, we spend a great deal of time focusing on making thoughtful, well-informed decisions. Meanwhile, we accept that outcomes will vary in the short term. But the key is that, over time, good decisions compound, both literally and figuratively.
Small Edges Add Up
Professional blackjack players aren’t looking for big wins. Instead, they’re looking for a small, consistent edge applied over many hands. In my decade of plying my craft at the tables, it felt monotonous at times, rather than the thrilling, like you might see in the movies. But that’s what separated a true professional advantage player from someone who says, “I can count cards.” A true professional is a master of all aspects of the game, and maintains discipline hand after hand after hand. In investing, it’s rarely one big decision that determines long-term success. It’s a series of smaller, thoughtful decisions, such as being properly diversified, tax-efficient, and rebalancing at the right times. That can run counter to the colleague at the water cooler who touts their “winning stock pick.” Individual decisions may not feel dramatic, but collectively, they matter a great deal.
Avoiding Big Mistakes Is Everything
At the table, a single lapse in discipline, such as betting too aggressively (or not aggressively enough) or making the incorrect playing decision, can undo a lot of good decisions. The same is true in investing. Large, emotion-driven mistakes, such as panic selling, overconcentration, or chasing trends, can have an outsized impact on long-term outcomes. At this stage of your financial life, success is often less about maximizing returns and more about avoiding those unforced errors.
A Final Thought
Blackjack taught me that success isn’t about predicting outcomes or chasing wins. It’s about discipline, consistency, and making sound decisions, over and over again. That’s the same mindset we bring to managing your wealth. Not every hand will go your way, but over time, the right approach tends to.
