MRK +12.6% on cancer vaccine push; Treasury buybacks cut yields to 4.71%

The 10-year Treasury yield settled at 4.71% Wednesday after the Treasury Department expanded its long-bond buyback program, knocking rates off a 20-month high and pulling the dollar lower with them. Gold climbed to $4,500. The VIX held at 15.8. WTI crude closed at $86.48. Two distinct catalysts ran on top of that macro reset.

$MRK +12.6% — personalized cancer vaccines

The day's largest single-name move belonged to $MRK, which gained 12.6% after Merck deepened its commitment to personalized cancer vaccines — a positioning move that raises the competitive stakes for $PFE and BioNTech in biotech's fastest-growing race. Pfizer shares rose in sympathy on the mRNA vaccine read-through. $LLY added 4.5%; today's news flow produced no clean dateable catalyst for Eli Lilly — the move tracked the broader healthcare session.

Rate-relief trade: $NEM, $COIN, $FCX

The Treasury's buyback program drove a clean rate-relief trade across three distinct categories. $NEM advanced 7.8% as gold's move to $4,500 translated directly into margin expectations for Newmont. $FCX gained 4.2% — copper demand from AI infrastructure and grid electrification remains the structural bid, with the weaker dollar adding a session-specific tailwind. $COIN jumped 9.6%, with three forces converging: falling Treasury yields, a Bitcoin price rally, and growing legislative optimism around the CLARITY Act, a bill that would establish federal crypto market structure.

Salesforce, Broadcom, GE

$CRM gained 5.1%. The Agentforce AI agent platform is reportedly tracking toward $1 billion in annual recurring revenue — a number the market continued to re-rate on Wednesday. $AVGO fell 4.6%; semiconductor chart sentiment turned bearish, and session momentum shifted further from Broadcom when Marvell surged after Google announced a separate AI chip deal — the warrant gives Alphabet an option on a $12.2 billion Marvell stake tied to nearly 59 million shares. $GE dropped 5.0%; no clean catalyst surfaced from today's filings or news flow.

Tesla and Thermo Fisher

$TSLA added 4.2%; today's headlines offer no dateable corporate catalyst — the move tracked the session's broad risk-on tone. $TMO also gained 4.2% on no company-specific filing.

Filings desk

$ABBV completed a $9.5 billion public bond offering Wednesday, with maturities running from 2028 to 2066 and coupons reaching 6.1% fixed. An AbbVie EVP separately sold $5.6 million in shares following option exercises. Routine scheduled sales arrived from $META (CFO Susan Li, $5.5 million), $RTX (General Counsel Maharajh Ramsaran, $3.1 million from exercised stock appreciation rights), $V (CFO, $2.5 million), $CVX (president, $1.3 million), and $BAC (CEO, $1.17 million).

What we set aside: One proxy/governance filing, 14 filings whose underlying events were more than 36 hours old, and nine tickers examined with no substantive news in the window were held from the lead.

The desk is watching for Treasury's use-of-proceeds disclosure on the long-bond buyback program and any Senate floor-vote timeline on the CLARITY Act.
