Last week the stock market did something it hadn’t done since late July: it fell. And the reason it fell tells you exactly what to watch this week, because the same force that pulled the market down is still sitting there, unresolved, beneath everything.
Here’s what happened. For most of the summer, the market climbed to record after record, largely ignoring a quiet problem building in the background: the interest rate the US government pays to borrow money for 30 years had been marching higher, reaching its highest level in nearly two decades. Last week, the market finally stopped ignoring it. Those high long-term borrowing costs sparked a genuine sell-off, and it hit the expensive technology and AI stocks hardest — the Nasdaq slid for five straight days at one point. The market that had shrugged off everything all summer suddenly couldn’t shrug off the bond market.
Then, on Friday, it bounced back hard. The Dow actually closed at a fresh record high, notching its best day since May, as those borrowing costs stabilized and buyers stepped back in. So the market enters this week in a genuinely unsettled state — shaken by the bond market, but not broken, and still near record highs on the strength of Friday’s rebound.
And now three enormous events land in the space of three days, each capable of deciding which way this uneasy market breaks.
On Wednesday, Nvidia reports its earnings. This is the single most important company in the entire AI trade, and by extension one of the most important for the whole market — one strategist put it bluntly, saying that if there’s a path to the S&P 500 reaching 8,000, it runs through Nvidia. Also on Wednesday, the government releases the core PCE inflation report, which is the Federal Reserve’s single most-watched measure of inflation — the number that most directly shapes what the Fed does next. And then on Friday, Fed Chair Kevin Warsh delivers his first-ever Jackson Hole speech, the marquee address at the central bank’s annual gathering, where markets will hang on every word for clues about where interest rates go from here.
Three make-or-break events, three days, one uneasy market still shadowed by a bond market that could reassert itself at any moment. Let me walk you through all of it — what to watch, what each outcome would mean, and how to position for a week that could set the market’s direction into the fall.
The Setup This Week
The defining tension this week is between an unresolved threat from below and three decisive catalysts arriving all at once. The threat from below is the bond market — long-term borrowing costs near 19-year highs that sparked last week’s sell-off and haven’t gone away. The three catalysts are Nvidia’s earnings (the referendum on the AI trade that’s carried the market), Wednesday’s core PCE inflation report (the Fed’s favorite gauge), and Warsh’s first Jackson Hole speech Friday (the clearest signal yet on the rate path). Any one of these could move the market sharply; together, in a single week, atop a nervous bond market, they make this one of the most consequential weeks of the year. The market is calm this morning, but that calm is unlikely to survive the week intact.
Opening Signal
Here’s the heart of it: this week pits the thing carrying the market (the AI boom) against the thing threatening it (rising borrowing costs), and by Friday we’ll know a lot more about which one wins.
The AI boom, embodied by Nvidia, has been the single biggest force lifting this market for two years. When Nvidia reports Wednesday, investors will be scrutinizing not just its profits but its guidance on future AI demand and the spending plans of its biggest customers — because that’s the real question hanging over the market: is the enormous AI investment boom sustainable, or is it starting to wobble? A strong report and confident outlook could reignite the rally and put that path toward S&P 8,000 back in play. A disappointment could confirm the fears that drove last week’s tech sell-off and pull the whole market down, because so much of the market’s value now rests on these few AI names.
The threat, meanwhile, is the bond market — and it connects directly to the fiscal story I wrote about in Friday’s bullion issue, where the national debt crossed $40 trillion and the Treasury had to step in to buy its own bonds to contain surging yields. Those same high long-term borrowing costs are the gravity pulling on the stock market. When the government must pay nearly 19-year-high rates to borrow, it lifts borrowing costs across the whole economy and makes the future profits of expensive growth stocks worth less today. Last week that gravity finally caught the market. This week, Wednesday’s inflation number and Warsh’s Friday speech will both feed directly into where those borrowing costs go next — a hot inflation print or a hawkish Warsh sends them higher and pressures stocks; a soft print or a dovish Warsh relieves them and frees the market to rise.
So the practical posture is to respect how genuinely two-sided this week is. The market could break sharply higher on a Nvidia blowout and a dovish Warsh, or sharply lower on a Nvidia stumble and a hawkish surprise, or chop violently as the signals conflict. With three binary events stacked in three days atop a nervous bond market, this is a week to hold your core positions, keep some protection and dry powder, and avoid big directional bets before the catalysts resolve. By Friday afternoon, the picture will be dramatically clearer than it is this morning.
Executive Signal — Premium
The market had its first losing week since late July, and the bond market was the cause. Long-term Treasury yields near 19-year highs sparked a genuine sell-off last week that hit AI and technology stocks hardest, with the Nasdaq sliding for five straight sessions at one point. The S&P 500 closed Friday at 7,674, down 1.4% on the week, though a strong Friday rebound (the Dow hit a fresh record, its best day since May) showed the dip was bought. The key takeaway: the market can no longer ignore the rising borrowing costs it shrugged off all summer, and those costs remain elevated and unresolved heading into this week.
Three make-or-break catalysts land in three days, making this one of the year’s most consequential weeks. Nvidia reports Wednesday — the single most important test of the AI trade, with a strategist noting that any path to S&P 8,000 runs through it (revenue expected near $92 billion, with all eyes on AI demand and hyperscaler spending guidance). Core PCE, the Fed’s preferred inflation gauge, also releases Wednesday. And Warsh delivers his first Jackson Hole speech Friday. Each is individually market-moving; together they could decide the market’s direction into the fall.
Warsh’s Jackson Hole debut is unusually high-stakes because no one knows his baseline. Having dismantled the Fed’s forward guidance, Warsh has signaled the speech will emphasize big-picture themes — monetary-policy framework, financial innovation, the limits of guidance — rather than near-term signals. But markets will parse every phrase for clues about the September 16 meeting. The uncertainty is genuine: a dovish or measured tone could rally stocks and ease yields, while any hawkish lean into the three regional presidents’ rate-hike dissents could compress rate-cut hopes and push yields higher. Watch for a potential two-stage reaction as analysts digest a deliberately academic speech.
The bond market is the unresolved threat beneath everything, and it ties to the $40 trillion debt story. The same fiscal dynamics that pushed the 30-year yield to a 19-year high — the debt crossing $40 trillion, the Treasury doubling its bond buybacks to contain yields — are the gravity pulling on stocks. This is the through-line connecting all three lanes right now: the fiscal strain driving gold to records is the same force threatening the equity rally through higher borrowing costs. Until long-term yields stabilize convincingly, the rally remains vulnerable, and this week’s inflation and Fed signals feed directly into where yields go next.
The genuinely healthy signal beneath the noise is the market’s broadening, which is the honest bull case. A striking development: the equal-weight S&P 500 is leading the market in 2026, and the largest equal-weight ETF just hit $100 billion — evidence the rally has broadened well beyond a handful of mega-cap tech names into a much wider range of stocks. US business activity grew at its fastest pace in over four years last week. This broadening is historically a sign of a healthy, durable bull market, and it means the market isn’t solely dependent on Nvidia — even if the AI names wobble, the broad market has genuine underlying strength. It’s the real counterweight to the bond-market threat.
Key Signals at a Glance — Premium
The market had its first losing week since late July: the S&P closed Friday at 7,674 (down 1.4% on the week) as long-term Treasury yields near 19-year highs sparked a sell-off that hit AI/tech hardest (a five-day Nasdaq slide). But Friday rebounded strongly — the Dow hit a fresh record, its best day since May.
Three make-or-break catalysts land in three days: Nvidia earnings Wednesday (the AI-trade referendum; “any path to S&P 8,000 runs through it,” revenue expected ~$92B), core PCE Wednesday (the Fed’s preferred inflation gauge), and Warsh’s first Jackson Hole speech Friday.
Warsh’s debut is high-stakes because his baseline is unknown — he’s signaled a big-picture, academic speech, but any hawkish lean toward the three regional presidents’ hike dissents could push yields up and compress rate-cut hopes into the September 16 meeting.
The bond market is the unresolved threat, tied to the $40 trillion debt story: the same fiscal strain driving gold to records (the Treasury doubling bond buybacks to contain 19-year-high yields) is the gravity pulling on stocks through higher borrowing costs.
The healthy signal: the equal-weight S&P is leading the market in 2026 (its largest ETF hit $100B), and business activity grew at its fastest pace in 4+ years — the rally is broadening beyond mega-cap tech, a sign of durability and the real counterweight to the bond threat.
Also this week: revised Q2 GDP and durable goods (Wednesday), consumer confidence (Tuesday), plus earnings from Salesforce, CrowdStrike, Dell, and Marvell. Bitcoin surged ~22% on the week, and crypto-related stocks jumped (Robinhood +14%, Coinbase +8%).
