Market Summary
Equities are charting fresh record territory at midday on October 6, with the S&P 500 (7840.25, +66.20, +0.85%) and Nasdaq Composite (27725.76, +227.41, +0.83%) both notching new all-time highs while the Dow Jones Industrial Average (51606.10, +338.29, +0.66%) keeps pace just below its own highs. The advance has broadened notably through the session — Briefing.com noted that by 11:55 ET, strength extended to all eleven S&P 500 sectors, a shift from the narrower, mega-cap-and-semiconductor-led pattern that has dominated much of the fall.
The dominant storyline is a wave of nuclear power purchase agreements tied to AI data-center demand. Constellation Energy (CEG) is surging on a 20-year PPA with Alphabet (GOOG) backing 890 MW of new nuclear capacity, lifting utility peers Vistra (VST) and NRG Energy (NRG) sharply higher and making Industrials (+2.4%) and Utilities (+2.3%) the session’s standout groups. Separately, semiconductor strength persists, with NVIDIA (NVDA) extending its breakout to fresh all-time highs and Marvell (MRVL) jumping after raising its FY28 revenue outlook to $20 billion.
A supportive macro backdrop is reinforcing the rally: WTI crude continues to slide toward the high-$80s on improved Middle East supply flows, and Treasury yields are modestly lower across the curve. Healthcare was the lone laggard earlier in the session (-0.7% at 10:55 ET) on weakness in Moderna (MRNA), though the sector reportedly turned positive as the broad-based rally took hold into midday. Small-caps have lagged, with the Russell 2000 slipping into slightly negative territory after an early gain, even as the S&P Mid Cap 400 rose a more modest 0.7%.

Stock Spotlight
Constellation Energy (CEG) is today’s most significant mover, surging 13.89% to $304.78 after announcing a landmark 20-year power purchase agreement with Alphabet (GOOG) supporting 890 MW of new nuclear capacity. The deal involves uprates at 11 existing units across six sites in the PJM grid, with the first uprate expected by 2028 and full capacity online before the end of 2032. A separate 15-year agreement covers an additional 2,700 MW of existing generation, enhancing CEG’s revenue visibility. Alphabet’s anchor-customer commitment is expected to enable more than $4.3 billion of investment by CEG in nuclear equipment and technology across Illinois, Pennsylvania, and New Jersey.
The agreement exemplifies a broader trend of large technology companies locking in long-term power commitments to support data-center growth, and mirrors Amazon’s recent 20-year, 690 MW deal with Constellation announced for Calvert Cliffs. The structure also responds to PJM’s “Bring Your Own Power” framework, incorporating demand-response provisions to address grid reliability concerns. While specific contract pricing and expected earnings contributions were not disclosed, the deal is driving sympathy rallies across the power complex, with Vistra (+10.95%) and NRG Energy (+7.87%) also among today’s top S&P 500 performers, and lifting the Industrials (+2.4%) and Utilities (+2.3%) sectors to the top of the sector leaderboard.
Bond Market & Treasuries
Treasuries are firmer at midday, extending a bounce from Monday’s weak start to the week. As of 11:30 ET, the 10-yr note was +11/32 with a yield of 5.260%.
Yield Check (as of 09:02 ET):
- 2-yr: 4.79% (-4 bps)
- 3-yr: 4.92% (-4 bps)
- 5-yr: 5.02% (-5 bps)
- 10-yr: 5.27% (-4 bps)
- 30-yr: 5.64% (-2 bps)
Key drivers include falling oil prices and relief in sovereign bond markets after French presidential candidate Marine Le Pen proposed increasing planned spending cuts to €140 billion over five years (up from €125 billion), easing pressure on French OAT yields that had been near year-highs. A $58 billion 3-year Treasury note auction is scheduled for results at 13:00 ET; the prior auction produced a high yield of 4.474%, bid-to-cover of 2.72, and indirect bid of 62.1%.

Economic Data
August Trade Balance: The U.S. trade deficit widened to $105.6 billion (Briefing.com consensus: -$93.7 billion) from a downwardly revised $92.8 billion in July (previously -$88.6 billion). Exports rose $4.5 billion versus July, while imports increased by a larger $17.2 billion. The key takeaway per Briefing.com: rising demand for crude oil and semiconductors drove both the export and import increases, which can be read as a constructive signal for global economic activity despite the larger-than-expected deficit.
Looking Ahead
- 13:00 ET today: Results of the $58 billion 3-year Treasury note auction
