The S&P gained 6% on the month, ending at 5,911. While stocks had a great month, at times it felt like the long-end of the treasury curve was the star of the show. Overall the reality of May was that it was a bit of a mess and it can be somewhat amazing to remember how much we forgot (that sounds like a Yogi-ism).
So What Passed For “News” During May?
From Liberation Day to Legal Limbo: Obviously May ended with court related headlines, first a block, then a reinstatement, but mid-May featured the 90-day pause on the reciprocal tariffs with China and along the way there were plenty of headlines about tariff negotiations (UK, China, EU) or lack thereof.
Patient Powell: We had the May 7 FOMC decision which left us with elevated risks to both sides of the Fed’s dual mandate as markets and yields on the front-end of the curve rose about 20bps on the month.
Moody’s U.S. Credit Downgrade (Finally): After years of playing the will-they/won’t-they game, Moody’s joined S&P and Fitch in downgrading U.S. debt. The market largely shrugged—but it gave us all an excuse to talk about fiscal r-star and bond vigilantes again.
AI Mountainhead: Fitting that we ended a month where Nvidia’s earnings and Google’s Veo 3 reminded us that the AI narrative isn’t slowing down withHBO’s made for TV movie, Mountainhead, which gave us an interesting take on a future filled with AI deep fakes unleashed by models controlled by tech elites with questionable (at best) morals.
Buffett Hands Over The Reigns: The Berkshire Hathaway Annual Meeting saw Warren Buffett announce that Greg Abel will succeed him as CEO by the end of the year. Buffett’s emphasis on patience, preparedness, and his belief in America are lasting lessons for a world that lacks the attention to learn them.
Speaking Of Lessons Learned
May gave us the opportunity to encounter a few pieces of wisdom.
“Uncertainty is Necessary” – Fisher Black’s Quiet Revolution. For a blog that frequently highlights that the future is inherently uncertain, that forecasting is unreliable, and admitting “I Don’t Know” if often the most honest and practical answer. In a month filled with tariff uncertainty, we revisited Black’s 1986 paper Noise to explain how markets need uncertainty. Without it, no one would trade. Without disagreement, there’s no liquidity. Noise isn’t a bug—it’s the feature.
“Markets Need Virtue, Not Just Valuation” – Lessons from the Vatican. While markets need trading, we talked about how business may need more virtue. Drawing from Rerum Novarum and Centesimus Annus, we heard that capitalism without a moral foundation risks becoming a thinly disguised totalitarianism. Work isn’t just a transaction; it’s a vocation.
“Ricardian Equivalence Is Dead—Long Live the American Consumer” The theory that people save when deficits rise? Not so much. May reminded us that consumers spend now, worry later. Debt is high, rates are high, and yet confidence surged.
“Debt is the Hidden Lever in ROE” – DuPont Deconstructed. We broke down DuPont analysis and asked: do investors really know how much leverage is baked into their portfolios? Financial performance looks great until rising rates hit the denominator.
“The Real Battle Is Over Narrative Ownership” - From Kyla Scanlon’s Screwtape-inspired take on spiritual fatigue to our own reflections on market memory and subconscious investing, May reminded us: the economy is shaped by stories—and whose story wins matters. As Howard Marks’ says: "the first cause [of market euphoria] is extreme brevity of the financial memory.”
What will June have in store for us, your guess is as good as mine. As always, the most important insight may be timeless: your behavior matters more than your forecast.
Onto June and Jobs
While May started with a 2Y Treasury yield at 3.61% and the 10Y to 4.18%. It ended with the 2Y up around 4% and the 10Y at 4.40%. The focus on deficits and the status of the One Big Beautiful Bill. As yields remain in focus, we’ll see if investors turn their attention to the so-called Fed Model popularized by Ed Yardeni to ascertain whether stocks offer sufficient value.
On the week ahead, stateside we’ll hear more about whether and how China is cheating on the tariff pause, tariffs in general and we’ll get some jobs data. We’ll also hear from some central bankers at the ECB and BoC in case you care.

XTOD: 30% or more of the Russian Air Force’s fleet of long-range nuclear-capable strategic bombers were reportedly damaged and/or destroyed during today’s operation by the Ukrainian Security Service (SBU), in what Russian milbloggers are calling “Russia’s Pearl Harbor”
XTOD: Light is distinctive only insomuch as it (like any massless particle) experiences no time, so all of its velocity vector points in the space directions, and therefore it moves with a purely *spatial* speed of c. c is merely the conversion factor between space and time
XTOD: The TACO trade may be over! Make way for the BURRITO trade, where Trump Backs Up Rapidly, Regrets It, Then Overreacts! (h/t Marc!). https://shrubstack.com/p/gag-in-may-and-shrub-away?r=at83k&utm_campaign=post&utm_medium=web&showWelcomeOnShare=false
XTOD: Ezra Klein: Part of what's happening when you spend seven hours reading a book is you spend seven hours with your mind on a given topic. But the idea that ChatGPT can summarize it for you is nonsense. The point is that books don't just give you information. They give you a container to think about a narrowly defined scope of ideas. Downloading information is obviously part of why you read books. But the other part is that books let you ruminate on a topic with a level of depth that's hard to achieve on your own.
XTOD: Maxim: Stay away from people who put money over everything. These people just build themselves expensive prisons.
