CEG +12.3% on a 20-year, 890 MW nuclear PPA with GOOGL dragged the whole IPP complex higher (VST +10.8%), OPCH ripped ~33% on a $32.05/sh cash takeout from CD&R and MCK, and MRVL squeezed higher on a bigger long-term AI model at its Investor Day. On the other side, storage got hit again on Toshiba capacity fears (STX -9.2%, WDC -6.9%) and MRNA -7.8% gave back its index-add pop. The tape faded from noon highs into the bell, but SPX still banked a record 7,818.93 while the Russell finished red.
SPX +45 pts to 7,818.93, its first-ever close above 7,800 and a fresh record, one session after the Nasdaq printed its own. The open was clean (SPX tagged a record minutes after the bell) and the index was running roughly +0.85% at the noon high around 7,840 before sellers leaned on it through the afternoon. We closed about two-thirds of the way up the range, giving back roughly a third of the day's gain. That's a decent close, not a strong one. Monday's 7,774 close is first support, with 7,800 the line bulls need to defend on any rate wobble tomorrow.
NDX/Comp +0.45% to a record 27,599.79 behind NVDA (pushing toward a $6T cap) and AMD on Lisa Su's "compute demand still outrunning supply" comment and the Foxconn print. But the internals were weak. Nasdaq decliners beat advancers 1,925 to 1,463, so the Comp record came from a handful of megacaps. With NVDA, AAPL and MSFT now above 21% of SPX, that kind of concentration is the story under the record. The Dow +0.49% was led by CSCO +4.5%, WMT +2.0% and HD +2.0%, with CRM -2.1% and BA -1.5% the drags.
RTY is the tell. The Russell opened +0.5%, flipped red by lunch and closed -0.57% at 2,830.97, the only major index lower. Small-cap health care did the damage: only 48 of 428 Russell health care names finished higher. Small caps won't hold a bid with the 10Y above 5.25% and the Fed in hiking mode (25bp to 3.75–4.00% in September), even on a day when yields fell.
NYSE advancers beat decliners 1,642 to 1,075 (~1.5:1), but Nasdaq ran 1,463 up / 1,925 down (~1:1.3). Ten of 11 SPX sectors finished green, led by XLU +2.96%, with only XLV -0.17% red. Large-cap breadth was respectable while small-cap and Nasdaq breadth was negative, so this was a cap-weighted record. Breadth faded with the index into the close.
VIX -0.51 to 15.01 (-3.3%) after trading a 14.96–15.54 range, so vol sellers kept control all session. A sub-15 handle is in reach, but with $61B of 10s and 30s still to clear this week and minutes tomorrow, owning cheap downside here is better than selling more.

Utilities put up their best day in a while, and this was an AI capex move more than a rates move. GOOGL's 20-year PPA with CEG funds 890 MW of uprates across six existing plants in IL, NJ and PA, with Constellation committing more than $4.3B to the build-out. That reprices the whole fleet of PJM nuclear and gas assets as contracted AI infrastructure. VST +10.8% and NRG moved in sympathy, and TLN caught a bid too. The read-through is straightforward. Every hyperscaler without a signed nuclear deal now has a reason to sign one, and the IPPs with uncontracted megawatts near load (VST, TLN, NRG) hold the scarce asset.
Technology lagged the index (+0.51%) despite the Nasdaq record because the group split in two. Compute was bid: NVDA and AMD printed highs and MRVL raised its long-term revenue targets, putting custom silicon back in the leadership group. Storage got hit for a second time on fears that Toshiba will add HDD capacity (STX -9.2%, WDC -6.9%), and KLAC slipped. A rotation inside semis is healthy. The worry is that the leaders keep narrowing.
Health Care was the only red sector and the main weight on small caps. MRNA -7.8% gave back its Nasdaq-100 re-entry pop (the add is effective before the open Friday, 10/9), ILMN pulled back from 52-week highs and SYK traded lower on the CEO transition. Russell biotech got hit much harder than the large-cap index shows. OPCH's take-private is the one bright spot and keeps the healthcare-services M&A theme alive.
This is the biggest corporate nuclear contract to date by size and tenor. The 20-year PPA covers 890 MW of new capacity from uprates (turbines, steam generators, digital controls) at six existing plants on the PJM grid, and Constellation will spend more than $4.3B on the build-out across 11 reactors. Because these are uprates rather than greenfield builds, timelines are shorter and execution risk is lower. Google pays for the capacity, so ratepayers don't carry it, which defuses the political problem of AI raising power bills. Gemini Enterprise gets embedded in CEG's outage management as a kicker. The stock went out at the $300 handle. The setup into next week is whether VST and TLN can announce deals of their own.
The deal is $32.05/sh cash, a ~37% premium to Monday's close, valuing the company at about $5.8B including debt. CD&R takes about 51% and MCK puts in roughly $1.4B for 49%, with close targeted in 1H27 pending the shareholder vote and regulators. The stock is trading just below the deal price, a tight spread that says the market sees low antitrust risk. For MCK, it's a capital-light way into home infusion. Read-through: watch other home-health and alternate-site names for a takeover bid.
Investor Day did what the bulls needed. Management dramatically raised its long-term revenue targets and gave a bullish multi-year outlook for AI infrastructure and custom silicon. Oppenheimer was already at $325, and Needham and Rosenblatt are at $300. The stock had fallen more than 10% after its last beat-and-raise, so this unwinds that disappointment. It closed back near $298, right at the cluster of Street targets. From here, holding the gap matters more than chasing it.
This is the second straight day of selling on reports that Toshiba may add HDD capacity, which threatens the pricing discipline behind the storage rally. Neither stock has fundamental news. This is positioning in two of the most crowded AI-adjacent longs this year (STX ~$806, WDC ~$411). We'd want to see this stabilize before calling it a buyable dip, because a second-day gap lower on volume points to de-grossing.
The stock gave back the index-add pop. MRNA rejoins the Nasdaq-100 before the open on Friday 10/9, so passive demand lands at Thursday's close. Fading index adds into the event is a well-worn trade, so expect chop into Thursday's MOC.
Cisco led the Dow on networking demand tied to the AI build-out, the same pattern as CEG and MRVL. The market is paying for picks-and-shovels exposure outside the GPU names.
STZ ~flat: FQ2 adj EPS $3.74 beat ~$3.61 consensus and revenue of $2.63B beat $2.54B. It reaffirmed FY27 EPS of $11.20–$11.90, but the midpoint sits below the ~$11.72 consensus, beer depletions fell 0.6% and beer operating margin compressed 160bp to 39.0%. Quality was fine but volumes are still soft. The 8:00 AM call decides whether the stock re-rates from 11x. The broader after-hours tape is quiet, with megacaps flat to fractionally higher (NVDA, AAPL, AMZN within ±0.1%).
Rates gave equities the room. The front end led the rally (2Y -4.2bp, 3Y -4.3bp) while the long end barely moved (30Y -1.7bp to ~5.65%). That bull steepener eases near-term hike pricing without solving the term-premium problem. Supply comes next: the 3Y cleared today, and the Treasury still has to sell a $39B 10Y reopening tomorrow (Wed) and a $22B 30Y reopening Thursday. Foreign demand has been thin, with indirects taking just 57.2% at the last 7Y versus a 64.6% average. If the 10Y tails, 5.30%+ is back in play fast, and that is the main threat to small caps and the bond-proxy rally in utilities and REITs.
Crude is the other variable. Oil sold off overnight on the G7's 100M-barrel release (front-loaded diesel) and Gulf exports running above pre-war levels on several days, then fully reversed. WTI closed +0.5% near $90 and Brent above $101, as reports of roughly 20 tanker attacks around Hormuz over the past month keep a floor under prices. Diesel above $6/gal is a tax on the consumer that the discretionary rally isn't pricing. Cheaper crude has been doing half the work of easing rate fears, so if crude rallies, the yield relief is likely to fade too.
SPX: Resistance at the 7,840 session high and 7,850 above it. Support at 7,800 (round number and breakout level), then 7,774 (Monday's close). A close back below 7,774 would turn the breakout into a failed one. Nasdaq Comp: 27,600 record close. Hold 27,477 (Monday's close) or the leadership is cracking. RTY: 2,850 is the pivot. It can't reclaim that without the 10Y moving below 5.20%, and 2,800 is the line to watch on the downside.
8:00 AM STZ earnings call. 1:00 PM $39B 10Y note reopening (the swing factor). 2:00 PM FOMC minutes from the Sept 15–16 meeting (the 25bp hike to 3.75–4.00%, 12-0); the bar is how many participants penciled in another hike. 3:00 PM G.19 consumer credit. After the close: LEVI Q3 (call 5:00 PM ET). Thu 10/8: PEP Q3 ~6:00 AM ET (Q&A 8:15 AM) opens staples earnings; $22B 30Y reopening; Gov. Waller speaks in Istanbul at 4:30 AM ET. Fri 10/9: DAL Q3 (call 10:00 AM ET); MRNA's Nasdaq-100 add effective pre-open. Mon 10/12: Columbus Day, with equities open and the bond market closed.
Power: CEG, VST, NRG and TLN all posted outsized single-day gains. Don't chase at the open. The second-day setup is to buy VST/TLN on a dip toward VWAP, since they are the names with uncontracted MW and deal optionality. Storage: STX and WDC are not catchable until the Toshiba story clears, so wait for a day that holds the low. MRVL: Keep long if the gap holds above ~$290. STZ: Treat it as a call-driven name. Owners at 11x get paid if management talks to depletion stabilization, while a guide toward the low end of $11.20–11.90 likely retests lows. Rates hedge: If you're long IWM or XLRE into 1 PM, consider TLT puts or a short in 10Y futures as auction insurance.
SPX closed at its first record above 7,800 and the Nasdaq added another, but the session faded from noon highs and the Russell finished red, so this was a narrow, cap-weighted advance. The important development was the CEG–Google nuclear contract. It confirms that power is now priced as AI infrastructure, and it rotated money into utilities on a day when yields helped only at the margin. The binary is 1:00–2:00 PM tomorrow, with a $39B 10Y reopening into thin foreign demand followed by minutes from a Fed that just hiked. A clean auction makes 7,800 a floor, while a tail puts 5.30%+ and a 7,774 retest back in play. Our lean: hold core long exposure in AI compute and power overnight, stay underweight small caps and long-duration bond proxies into the auction, and buy any 7,775–7,800 dip after 2 PM if the 10Y holds below 5.30%.
