The AI Earnings Wave Hits the PPI Wall
Wall Street closed Wednesday near record territory as tame July inflation data and two blockbuster AI earnings reports gave investors just enough to keep buying. The S&P 500 added 0.26% to 7,748.50 — within striking distance of its all-time high — while the Nasdaq rose 0.54% on the back of a 112% revenue surge from CoreWeave and a record quarter from Cisco. This morning the tone shifts: July PPI prints at 8:30 a.m. ET, and a hotter-than-expected read could put Wednesday's optimism to the test before the opening bell.
July CPI rose 0.1% MoM and 3.4% YoY — exactly in line with estimates — and that was enough to push the S&P 500 up 0.26% to 7,748.50 on Wednesday, its strongest level since its all-time closing high of 7,819.91. Two AI infrastructure earnings reports did the heavy lifting: CoreWeave reported Q2 revenue of $2.58 billion, up 112% YoY, and Cisco posted a record Q4 with $17.3 billion in revenue, up 18% YoY, guiding fiscal 2027 revenue to $72.2–$73.4 billion. The Dow barely moved (−0.04%) as gains stayed concentrated in tech. Overnight, Nikkei futures climbed 1.61% on the AI sentiment spillover while the Strait of Hormuz standoff kept WTI crude near $82 with a persistent risk premium. This morning, July PPI prints at 8:30 a.m. ET — a hotter number could reawaken September rate-hike fears and challenge Wednesday's momentum before the open.
CPI Meets Consensus, AI Earnings Beat It — S&P 500 Advances to 7,748
The Bureau of Labor Statistics reported July CPI at 3.4% YoY — easing from June's 3.5% and matching the consensus estimate precisely. On a MoM basis, prices rose just 0.1%. Core CPI (ex-food and energy) rose 0.2% MoM, also in line. The data was good enough to push money markets below a 50% probability of a September Fed rate hike and pulled the 10-year Treasury yield down roughly 3 basis points to approximately 4.65%.
CoreWeave reported Q2 revenue of $2.58 billion, up 112% YoY, beating the LSEG consensus of $2.56 billion. Adjusted operating income came in at $128 million — nearly double the consensus estimate of $66 million — and adjusted operating income margin hit 5% versus the 2.7% expected. The company raised its full-year 2026 revenue guidance to $12.4–$13.2 billion and lifted capex guidance to $35–$39 billion annually. Shares surged roughly 14–19% in extended trading. Note: CoreWeave carries $35 billion in debt and remains GAAP unprofitable, so the margin improvement is operationally meaningful but should be viewed in context of the company's stage of development.
Cisco reported Q4 FY2026 revenue of $17.3 billion, up 18% YoY, beating its own guidance high-end. Non-GAAP EPS of $1.22 rose 23% YoY. Q4 total product orders jumped 35% YoY, with hyperscaler AI infrastructure orders reaching $4 billion in the quarter alone — bringing the full FY2026 AI total to $9.3 billion, roughly 4.5 times the prior year. Management guided FY2027 revenue to $72.2–$73.4 billion (up ~15% at the midpoint) and called the current environment a "networking supercycle" driven by agentic AI adoption.
The Dow closed at 53,770.27, down just 21.58 points (−0.04%), extending a mild three-session losing streak as gains remained concentrated in tech rather than blue-chip industrials. VIX fell 4.78% to 14.55, reflecting easing near-term anxiety. In Asia overnight, Japan's Nikkei rose 1.61% on AI earnings momentum spillover. S&P 500 futures pointed up about 0.13–0.20% ahead of the open, with all eyes on the 8:30 a.m. ET PPI release.
Two Narratives, One Session — and They're Pulling in Opposite Directions
Wednesday told two distinct stories. The first was relief: inflation is cooling, and the Fed may have room to hold in September. That's the bond market's message — yields slipped, short-duration Treasuries outperformed, and rate-hike probability faded below 50%. For equities, that backdrop is fuel.
The second story is more complicated. Energy prices remain elevated because the Strait of Hormuz — through which roughly one-fifth of the world's oil supply transited before the 2026 Iran conflict — remains effectively closed. Iran's newly appointed Secretary of the Supreme National Security Council stated the waterway will not reopen until the U.S. meets specific ceasefire conditions, including easing sanctions and paying war reparations. WTI crude settled near $82–$83 per barrel. That keeps a persistent risk premium in the energy complex, which feeds upstream inflation — and that's exactly what Thursday's PPI report is designed to capture.
The CPI-PPI sequencing matters here. CPI measures what consumers pay; PPI measures what producers receive. When energy costs are structurally elevated, PPI tends to lag CPI on the way down — but can spike faster when supply chains absorb new shocks. A hot July PPI this morning would signal that pipeline inflation hasn't cleared, even if headline CPI looks benign. That would be unwelcome news for the Fed members already dissenting toward a hike.
From CPI Relief to PPI Risk: How Wednesday's Calm Could Unravel by 9 a.m.
CPI Cleared. PPI Is the Next Gate. Here's What's at Stake in Each Corner of the Market.
The 10-year yield at ~4.65% reflects a market that believes the Fed is more likely to hold in September than hike. A soft PPI today would cement that view and could push the 10-year toward 4.55%–4.60%. A hot PPI — particularly if energy service costs spike — would reignite hike pricing and could lift yields back above 4.70%, inverting Wednesday's relief trade.
Tech and AI names have been the clearest beneficiary of the rate-hold narrative: lower rate-hike risk = higher DCF valuations for growth stocks. The Nasdaq's 0.54% gain Wednesday was powered by CoreWeave, Super Micro Computer, Dell, and Nvidia. If PPI stays tame, that group leads again. If yields spike, expect rotation out of growth and into defensives — a pattern that has played out twice already this summer.
The Q2 GDP advance estimate came in at 1.5% annualized — down from 2.1% in Q1. That's enough growth to keep recession fears at bay, but not enough to make a strong case for additional Fed tightening on demand grounds alone. The Hormuz disruption remains the wild card: energy costs elevated via a supply shock are stagflationary, not demand-driven, and rate hikes are a blunt tool for that problem.
Beyond PPI: weekly jobless claims also print today. Retail sales follow Friday. FOMC minutes on August 19 will reveal how serious the three dissenting hawks actually are. And Nvidia reports August 26 — the ultimate litmus test for whether the AI capex cycle Cisco and CoreWeave are describing is translating into chip demand.
July PPI (Final Demand), released 8:30 a.m. ET today. Consensus: +0.2% MoM. The prior month (June) showed a −0.3% decline in final demand — a low base. Energy services are the variable to watch. A print above +0.4% MoM would likely force markets to reprice September Fed odds above 50% and cap today's equity rally.
Tech Wins Cleanly; Utilities and Defensives Benefit From Rate-Hold Optimism; Energy Stays Complicated
Technology was the strongest S&P 500 sector on Wednesday, driven by CoreWeave's afterhours surge and Cisco's record beat reported during the session. Nvidia gained 3.03% on the day — its best single-session move in weeks — while Dell advanced nearly 10% and Micron rose ~5%, all riding the AI infrastructure narrative. The XLK benefited directly from both cooling CPI (lower discount rates for growth stocks) and the earnings confirmation that capex spending is accelerating, not slowing.
Note: XLC's −2.1% decline reflects Tuesday's session (Aug. 11), driven by AppLovin's sharp drop as the sector's biggest loser. Wednesday's CPI day partially offset that, but XLC remains under pressure from Hormuz-related uncertainty in advertising-sensitive names and ongoing volatility from social media platform ad spending concerns. AppLovin (APP) was cited as the S&P 500's major loser in Tuesday's session.
Energy is in an unusual position: WTI crude near $82–$83 is elevated by historical standards due to Hormuz supply disruption, which should theoretically boost E&P names. But the same supply shock creates stagflation risk that weighs on the broader market and introduces uncertainty about demand destruction. Watch how XLE responds to today's PPI — energy services in the PPI basket will be a key inflation signal for the Fed's September calculus.
When Earnings, Inflation, and Geopolitics All Collide — This Is the Job
Wednesday was a perfect encapsulation of the multi-variable environment finance professionals navigate daily: a macro print (CPI), two major earnings releases (CoreWeave, Cisco), a geopolitical overhang (Hormuz), and a forward-looking catalyst (PPI this morning). Being able to explain how each of these interacts — rather than treating them as isolated events — is what separates strong interview candidates from average ones.
Clients with fixed-income exposure need to understand why a 3.4% CPI print can move bond prices even when it matches expectations. The market reaction is about expectation management, not just the number itself. This is a great week to reinforce why duration matters: the 10-year yield's 3 bps drop after CPI is small, but it translates to meaningful price changes for long-duration bond portfolios. High-net-worth clients also want clarity on how Hormuz-driven energy inflation affects their real purchasing power — a nuanced conversation that goes beyond the headline number.
Cisco's Q4 report is a case study in guidance credibility. The company raised AI infrastructure order guidance from $5 billion to $9 billion mid-year and then delivered $9.3 billion — a pattern of systematic upside that signals operational visibility rather than one-time luck. Analysts covering networking, cloud infrastructure, and semiconductors should model the FY2027 $7.5 billion AI infrastructure revenue target against consensus and flag whether the implied growth rate is already in the stock. CoreWeave's adjusted operating income margin of 5% versus a 2.7% consensus estimate is a meaningful inflection — but do not call it a profitability story until GAAP losses narrow materially from the current $626 million quarterly net loss level.
The AI infrastructure spending cycle — confirmed again by Cisco and CoreWeave this week — is generating significant M&A and capital markets activity. CoreWeave itself went public in March 2025 and has already raised substantial debt capital to fund its GPU buildout. The Cisco result signals that networking supercycles attract enterprise buyers, not just hyperscalers. For IB candidates, this is the backdrop for data center REIT transactions, infrastructure debt issuance, and strategic acquisitions in the semiconductor supply chain. Understanding why Cisco's Q4 product orders grew 40% YoY — and what that means for the next layer of the value chain — is exactly the kind of sector intelligence interviewers probe for.
Three Questions You Could Face in a Finance Interview Today — and How to Answer Them
- "CPI came in at 3.4% YoY and markets rallied. But inflation is still above the Fed's 2% target — how does that make sense?" A strong answer explains that markets price on the margin of surprise, not the absolute level. CPI matching consensus removed the tail risk of a hawkish shock. The Fed's September decision is still live, but the probability shifted below 50%, which is enough for growth stocks to rally on lower expected discount rates.
- "Cisco's non-GAAP EPS beat consensus by roughly 23 cents. Is that a genuine operational beat or a financial engineering story?" Point to the revenue beat ($17.3B vs. ~$16.8B consensus), the 35% product order growth, and the FY2027 guidance raise. Those are real demand signals. The non-GAAP adjustment to exclude stock-based compensation is standard for tech companies — the key is whether the underlying cash generation supports it. Q4 cash flow from operations of $5.4 billion, up 27% YoY, suggests it does.
- "The Strait of Hormuz has been disrupted since March 2026. Why hasn't oil spiked to $120+ again like it did initially?" The initial closure drove Brent above $120. Since then, U.S. naval escorts, Strategic Petroleum Reserve releases, and demand destruction have capped prices. Markets have partially priced a prolonged disruption rather than a binary reopen event. The current ~$82–$83 WTI still reflects a meaningful risk premium relative to pre-conflict levels.
- What NOT to say: Don't say markets rallied because "inflation is under control." At 3.4% YoY, it is not under control — it is simply not accelerating. There's a crucial difference, and interviewers in macro-oriented roles will catch that imprecision immediately.
The PPI measures the average change over time in prices received by domestic producers for their output — essentially, what businesses charge each other before goods and services reach the consumer. It is a leading indicator of consumer inflation: when producer input costs rise, companies often pass those increases downstream, eventually showing up in CPI. Today's July PPI release is particularly important because the Hormuz disruption has elevated energy commodity prices throughout the production pipeline. If Tuesday's CPI showed a cooling consumer price environment while PPI shows rising producer costs — especially in energy services — it signals pipeline inflation that could pressure future CPI readings and inform the Fed's September decision.
Sound Smart Before 9 a.m.
"Wednesday's CPI was a permission slip, not a victory lap. Inflation at 3.4% matched expectations, which was enough to push September rate-hike odds below 50% and let tech run on the CoreWeave and Cisco beats. But this morning's PPI is the more interesting print — if energy service costs show through in the producer pipeline, the Fed's three hawkish dissenters from the July meeting get louder, and this rally has a ceiling. I'm watching the 8:30 print closely before deciding how to read today's open."
