Take this excerpt on psychology from his new book, “How Not To Invest,” which he shared in a recent piece for Bloomberg:
Trick Your Lizard Brain
Nobel laureate Paul Samuelson once said, “Investing should be more like watching paint dry or watching grass grow. If you want excitement, take $800 and go to Las Vegas.” While the dopamine hit that comes from a risky stock bet paying off may be enjoyable, passive management is the better option for most investors looking to grow long-term wealth.
The catch is that you must take steps to protect yourself from, well, yourself. To do so, set up a “mad-money account” — or a cowboy account, as it’s sometimes called. Add less than 5% of your liquid capital, so maybe $5,000 if you’re liquid enough to have $100,000 as a safety net. Now you can indulge your inner hedge fund manager without jeopardizing anything too material.
If it works out, you’re more likely to let those winners run because it’s for fun and not your real money. If it’s a debacle, appreciate the terrific lesson that should remind you that this is not your forte.
In his book, Barry shares a little more on what he personally does:
In my cowboy account, using 2% of my liquid net worth, I play the dumbest game possible: Market timing with out-of-the-money stock option calls…
He discusses specific trades he’s made. I’ll let you buy the book if you really want the details.
Here’s his bottom line.
Regardless of the results, it allows my inner junkie to leave my main portfolio alone. That is the true value of the cowboy account — my real money remains unmolested by me and my big dumb lizard brain.
Like most of us, Barry is not a machine. He is a human with a brain. And when your brain is mismanaged, it can be your worst enemy.
The idea of having a “cowboy account” is not without its issues. Some of you might say it could be a slippery slope towards costlier risk taking. This advice certainly isn’t for everybody. But let’s also not pretend like living in denial of your instincts and biases isn’t risky either.
Personally, I’ve taken Samuelson’s advice much more literally. Occasionally, I like to play craps live in a casino. That’s the game where you often hear crowds of people cheer loudly as they engage in the mania of a “hot” table. I won’t get into too much detail, but it’s a game where I can lose enough that it’s memorably painful but not so much that it’s material to my finances. Importantly, it satiates my risk appetite, and it gives me renewed appreciation for my financial plan at relatively low cost.
In some ways, investing is like dieting: For many people, attempting to cut out junk food entirely just doesn’t work.
If you want to learn more about how real people can better navigate the treacherous world of investing, buy Barry’s book. He’s got real world solutions for your real world challenges.

Barry Ritholtz ‘How not to Invest’
I was shocked and humbled to learn that Barry mentioned me in “How NOT To Invest.” I’ve been reading his blogs since before the financial crisis. He’s had a huge impact on how I think and write about markets.

I was on The Compound & Friends podcast on Thursday with Andrew Beer of Dynamic Beta Investments, the legendary Josh Brown, and the brilliant Michael Batnick. We covered a lot. Trump trade policy, stock market sentiment, credit, hedge funds, diversification, and more! Listen on Apple Podcasts, Spotify, YouTube, and beyond!
There were several notable data points and macroeconomic developments since our last review:
🛍️ Consumer spending ticks up. According to BEA data, personal consumption expenditures increased 0.4% month over month in February to an annual rate of $20.4 trillion.
🎈 Inflation heats up. The personal consumption expenditures (PCE) price index in February was up 2.5% from a year ago. The core PCE price index — the Federal Reserve’s preferred measure of inflation — was up 2.8% during the month, up from January’s 2.7% rate. While it’s above the Fed’s 2% target, it remains near its lowest level since March 2021.
On a month over month basis, the core PCE price index was up 0.38%. If you annualized the rolling three-month and six-month figures, the core PCE price index was up 3.5% and 3.1%, respectively.
💼 Unemployment claims tick lower. Initial claims for unemployment benefits declined to 224,000 during the week ending March 22, down from 225,000 the week prior. This metric continues to be at levels historically associated with economic growth.
👎 Consumer vibes deteriorate. From the University of Michigan’s March Surveys of Consumers: “Consumer sentiment confirmed its early month reading and fell for the third straight month, plummeting 12% from February. The expectations index plunged a precipitous 18% and has now lost more than 30% since November 2024. This month’s decline reflects a clear consensus across all demographic and political affiliations; Republicans joined independents and Democrats in expressing worsening expectations since February for their personal finances, business conditions, unemployment, and inflation. Consumers continue to worry about the potential for pain amid ongoing economic policy developments. Notably, two-thirds of consumers expect unemployment to rise in the year ahead, the highest reading since 2009. This trend reveals a key vulnerability for consumers, given that strong labor markets and incomes have been the primary source of strength supporting consumer spending in recent years.”
The Conference Board’s Consumer Confidence Index ticked lower in March. From the firm’s Stephanie Guichard: “Of the Index’s five components, only consumers’ assessment of present labor market conditions improved, albeit slightly. Views of current business conditions weakened to close to neutral. Consumers’ expectations were especially gloomy, with pessimism about future business conditions deepening and confidence about future employment prospects falling to a 12-year low. Meanwhile, consumers’ optimism about future income—which had held up quite strongly in the past few months—largely vanished, suggesting worries about the economy and labor market have started to spread into consumers’ assessments of their personal situations.”
👍 Consumers feel a little better about the labor market. From The Conference Board’s March Consumer Confidence survey: “Consumers’ views of the labor market improved slightly in March. 33.6% of consumers said jobs were ‘plentiful,’ unchanged from February. 15.7% of consumers said jobs were ‘hard to get,’ down from 16.0%.”
Many economists monitor the spread between these two percentages (a.k.a., the labor market differential), and it’s generally been reflecting a cooling labor market.
💳 Card spending data is holding up. From JPMorgan: “As of 18 Mar 2025, our Chase Consumer Card spending data (unadjusted) was 1.8% above the same day last year. Based on the Chase Consumer Card data through 18 Mar 2025, our estimate of the US Census March control measure of retail sales m/m is 0.46%.”

From BofA: “Total card spending per HH was up 1.5% y/y in the week ending Mar 22, according to BAC aggregated credit & debit card data. Entertainment spending growth has been weak since late Feb. The recent partial recovery has been led by the Midwest & South. Total card spending growth in the DC area remains weaker than the rest of the country, likely due to the impact of DOGE cuts.”
⛽️ Gas prices tick higher. From AAA: “With Spring Break in full swing, drivers are paying more at the pump compared to last week. The national average for a gallon of gas went up 3 cents since last Thursday to $3.15. Gas prices typically start going up this time of year and peak during summer. But the national average is still about 40 cents lower than last year, due to tepid gasoline demand and weak crude oil prices. “
🏠 Mortgage rates tick lower. According to Freddie Mac, the average 30-year fixed-rate mortgage declined to 6.65% from 6.67% last week. From Freddie Mac: “The 30-year fixed-rate mortgage ticked down by two basis points this week. Recent mortgage rate stability continues to benefit potential buyers this spring, as reflected in the uptick in purchase applications.”
🏠 Home prices rise. According to the S&P CoreLogic Case-Shiller index, home prices rose 0.6% month-over-month in January. From S&P Dow Jones Indices’ Nicholas Godec: “Rising mortgage rates throughout the year elevated monthly payment burdens, which, combined with already high home prices, pushed affordability to multi-decade lows in many regions. This likely contributed to subdued activity in the back half of the year, with both buyers and sellers exercising caution. Inventory constraints also remain a challenge, particularly in legacy metro areas, where limited new construction continues to restrict supply.”
🏘️ New home sales rise. Sales of newly built homes increased 1.8% in February to an annualized rate of 676,000 units.
🏢 Offices remain relatively empty. From Kastle Systems: “Peak day office occupancy was 63.1% on Tuesday last week, up two tenths of a point from the previous week. In Austin, the South by Southwest conference and festival led to lower daily occupancy nearly every day. And in Houston, CERAWeek 2025 resulted in significantly lower occupancy last Thursday and Friday before rebounding after the conference, peaking at 71.2% on Tuesday. The 10-city average low was on Friday at 34.3%, down 2.1 points from last week.”
🏭 Business investment activity ticks lower. Orders for nondefense capital goods excluding aircraft — a.k.a. core capex or business investment — declined 0.3% to $74.99 billion in February.
Core capex orders are a leading indicator, meaning they foretell economic activity down the road. The growth rate had leveled off a bit, but they’ve perked up in recent months.
👍 Activity survey signals growth. From S&P Global’s March Flash U.S. PMI: “A welcome upturn in service sector activity in March has helped propel stronger economic growth at the end of the first quarter. However, the survey data are indicative of the economy growing at an annualized 1.9% rate in March and just 1.5% over the quarter as a whole, pointing to a slowing of GDP growth compared to the end of 2024. Near-term risks also seem tilted to the downside. Growth is concentrated in the service sector as manufacturing fell back into decline after the frontrunning of tariffs had temporarily boosted factory output in the first two months of the year. Similarly, some of the March upturn in services was reportedly due to business picking up after adverse weather conditions had dampened activity across many states in January and February, which could prove a temporary bounce.”
At the same time inflationary pressures appear to be building. From the report: “A key concern over tariffs is the impact on inflation, with the March survey indicating a further sharp rise in costs as suppliers pass tariff-related price hikes on to US companies. Firms’ costs are now rising at the steepest rate for nearly two years, with factories increasingly passing these higher costs onto customers. Thankfully, from the Federal Reserve’s perspective, services inflation remains relatively subdued, but this reflects the need to keep prices low amid weak demand, which will harm profits.”
Actions speak louder than words: We are in an odd period given that the hard economic data has decoupled from the soft sentiment-oriented data. Consumer and business sentiment has been relatively poor, even as tangible consumer and business activity continue to grow and trend at record levels. From an investor’s perspective, what matters is that the hard economic data continues to hold up.
Think long term: For now, there’s no reason to believe there’ll be a challenge that the economy and the markets won’t be able to overcome over time. The long game remains undefeated, and it’s a streak long-term investors can expect to continue.
