It's one of those days where the market feels like it's being pulled in two directions at once. On one hand, you've got oil spiking above $100 a barrel for the first time since July, which is reviving all those inflation worries that just won't quit. On the other, you've got some genuinely exciting AI news from the likes of Meta and Cloudflare that's giving tech stocks a reason to smile. But overall, the scales tipped toward the negative, and U.S. equities slid across the board by midday Wednesday.

Let's start with the oil story. West Texas Intermediate crude rose 3.6% to $96.35 a barrel, while Brent added 3.5% to $101.33. The catalyst? U.S. forces destroyed five Iranian tankers near Kharg Island in retaliation for attempted missile attacks on a U.S. warship. It's a reminder that the war with Iran is far from over, and the energy market is feeling every bit of it.

That energy move fed straight through to rates. The 10-year Treasury yield climbed six basis points to 4.85%, the highest since October 2023. And here's the kicker: this happened even after the Treasury Department tripled its scheduled buyback to $6 billion of off-the-run notes and bonds for Thursday. So much for that attempt to calm things down.

Rate-hike expectations are doing the rest of the damage. Markets are pricing roughly a 60% chance of a 25-basis-point Fed hike after Friday's strong jobs report. A Reuters poll released Wednesday showed a rising number of economists now expect at least one increase. So the narrative is clear: oil goes up, inflation fears go up, and the Fed might have to act.

Across U.S. equity markets by midday Wednesday, losses were broad-based. Only energy held positive territory among the eleven S&P 500 sectors. The S&P 500 fell 0.5% to 7,631, while the Dow Jones Industrial Average dropped 439 points, or 0.8%, to 52,348. The Nasdaq 100 held up better, down 0.4% to 29,398, cushioned by a violent rotation inside big tech.

Meta Platforms Inc. (META) and Cloudflare Inc. (NET) were the standout exceptions, up 6.7% and 10%, respectively, on fresh AI product news. We'll get into the details in a bit, but suffice it to say, these two are having a good day.

The Russell 2000 was the clear laggard, falling 1.2% to 2,925. Higher borrowing costs hit the most rate-sensitive corner of the market hardest, and small caps are feeling the pinch.

Wednesday's Performance In Major U.S. Indices

For those tracking via ETFs, the Vanguard S&P 500 ETF (VOO) fell 0.5%, the SPDR Dow Jones Industrial Average ETF Trust (DIA) slid 0.8%, the Invesco QQQ Trust (QQQ) eased 0.4%, and the iShares Russell 2000 ETF (IWM) dropped 1.2%.

Energy Outperforms Among Sectors

As mentioned, energy was the only sector in the green. The Energy Select Sector SPDR Fund (XLE) was up 0.7%, while the Utilities Select Sector SPDR Fund (XLU) was the worst performer, down 1.3%. That makes sense: when rates go up, utilities, which are bond proxies, tend to suffer.

The Consumer Discretionary Select Sector SPDR Fund (XLY) and the Industrials Select Sector SPDR Fund (XLI) both fell 1.2%. The Consumer Staples Select Sector SPDR Fund (XLP) and the Real Estate Select Sector SPDR Fund (XLRE) were close behind. The Technology Select Sector SPDR Fund (XLK) was effectively flat, and the Health Care Select Sector SPDR Fund (XLV) and Financial Select Sector SPDR Fund (XLF) each shed less than half a percent.

Wednesday's Stock Movers

Now let's talk about the movers and shakers. On the upside, Sunbelt Rentals Holdings, Inc. (SUNB) was the single best performer in the Russell 1000, rallying 11% after reporting adjusted fiscal first-quarter EPS of $1.18 that beat consensus on better-than-expected revenue. Specialty rental revenue rose 25.3% year-over-year, the company raised full-year fiscal 2027 revenue growth guidance to 6%-9% from 4.5%-7.5%, and declared its first quarterly dividend at $0.30 a share. That's a lot of good news in one report.

Cloudflare, Inc. jumped 10% after unveiling a security partnership with OpenAI around its Daybreak service. This is a concrete validation of CEO Matthew Prince's pitch that Cloudflare sits at the center of machine-to-machine internet traffic. And the market seems to agree. Zscaler, Inc. (ZS) rose about 3% in sympathy, and the read-through bid extended across the edge and observability complex. Datadog, Inc. (DDOG) climbed 6.6% and Akamai Technologies, Inc. (AKAM) added 6.3%. These moves appear to be a read-through bid rather than anything stock-specific.

Meta's 6.5% advance rounded out the top five, driven by the Muse launch. Mizuho called it "the beginning of a substantial product cycle," and KeyBanc reiterated that the market underestimates Meta's AI positioning. It's a good day to be in the AI game, apparently.

Astera Labs, Inc. (ALAB) and Micron Technology, Inc. (MU) also finished among the stronger large caps, up 5.7% and 2.3% respectively. SK Hynix Inc. (SKHY) rallied over 5% after Korean brokerage firm Mirae raised the stock price target.

On the downside, Casey's General Stores, Inc. (CASY) was the worst name in the index, plunging 14.3% after Tuesday's post-close fiscal first-quarter report. Revenue of $5.68 billion topped the $5.57 billion consensus, but management guided fiscal 2027 inside same-store sales growth to just 2%-5% and same-store fuel gallons to roughly flat, plus or minus 1%. That conservative outlook overwhelmed the top-line beat. Sometimes it's not about what you did, but what you say you're going to do.

Chewy, Inc. (CHWY) fell 9.5% after this morning's fiscal second-quarter print. Adjusted EPS of 36 cents landed in line with consensus, and net sales rose 7.3% to $3.33 billion, narrowly ahead of the $3.32 billion estimate. But management raised only the low end of its full-year adjusted EBITDA margin outlook and said it is not counting on a meaningful consumer recovery. That's a cautious tone that investors didn't appreciate.

Ubiquiti Inc. (UI) dropped 10.5%, extending a multi-week de-rating tied to gross margin compression and rising component and shipping costs. It's been a rough patch for Ubiquiti, and today is no exception.

Vertiv Holdings Co (VRT) slid 8.5% and X-Energy, Inc. (XE) lost 9.3%. Both sit at the long-duration end of the AI power and data center trade, the part of the market most exposed to a 10-year yield at three-year highs. The selling looks like positioning ahead of this week's CPI and PPI prints rather than a news event. When rates are rising, the stocks that benefited from low rates for long-duration projects tend to take a hit.

So, what's the takeaway? Oil is back above $100, and that's a big deal. It's feeding into rate expectations, and that's putting pressure on stocks, especially the rate-sensitive ones. But there's still money to be made in AI, as evidenced by the moves in Meta, Cloudflare, and their peers. It's a market of two halves, and the key is to know which half you're in.

As always, keep an eye on the upcoming CPI and PPI prints. They could set the tone for the next leg of this market. And with oil at these levels, inflation is likely to be a hot topic. Stay tuned.
