Nvidia's Record Buyback Can't Stop the Chip Selloff

Sep 28, 2026
Bobby Quant Team

💡 Key Takeaway

Geopolitical risk and 5.26% Treasury yields are repricing semiconductors faster than any single company's buyback can offset.

A Rejected Peace Deal, $100 Oil, and a Chip Rout

President Trump rejected Iran's weekend peace proposal, calling the terms unacceptable, and reportedly told aides he expects strikes to resume after November's midterms. The market reaction was immediate: Brent crude spiked above $108 before settling near $100, still up roughly 2.7% in 24 hours, while the United States Oil Fund rose 3.3%. Energy was the only S&P sector in the green, up 0.9%, though even the largest oil majors moved less than 2% — a sign traders see this as a geopolitical spike, not a structural supply shock.

Equities took the hit. The Nasdaq Composite fell about 1%, the S&P 500 dropped 0.8%, and the Dow declined 0.7%, with 17 of 30 Dow components trading lower. Nvidia was the glaring exception, up 2.1% after announcing a $150 billion expansion of its buyback program, bringing total authorization to $235 billion — the largest share repurchase ever presented by an American company. It also rolled out OpenShell, an AI agent-safety platform.

Every other major chip name sold off hard. SK Hynix fell 5.9%, Qualcomm 5.7%, AMD 5.2%, and Micron 3.7%. The proximate causes: rising yields and reports that OpenAI will pause back-end training until further notice. The 10-year Treasury yield climbed to 5.26%, its highest since spring 2002, which crushed gold nearly 4% as investors rotated into high-yielding safe havens. Meanwhile, the U.S. and China agreed to cut tariffs on $60 billion of goods through January 2027 — a quiet positive buried under the risk-off tape.

Rates Are Repricing Everything, Including AI

The story here isn't Nvidia's buyback — it's the 10-year Treasury at 5.26%, a level not seen since 2002. When the risk-free rate climbs that high, long-duration growth assets get repriced whether or not their fundamentals change. Semiconductors sit at the epicenter because they combine high multiples with cyclical exposure to energy costs and global trade. A buyback can support one stock's price, but it can't lower the discount rate applied to the entire sector.

The OpenAI training pause adds a second layer of uncertainty. If frontier labs throttle back-end compute spending even temporarily, the demand curve for high-end memory and accelerators gets questioned — which is exactly why Micron, SK Hynix, and AMD sold off harder than the broader market. This is a sentiment shock, not yet a confirmed demand shock, but markets price the former before they can verify the latter.

The week ahead is loaded: job openings Tuesday, core inflation and final Q2 GDP Wednesday, September jobs Friday with forecasts of just 84,000 new positions versus August's 162,000. Any upside inflation surprise or hot wage number could cement another Fed hike and push yields even higher. Micron's Wednesday evening earnings — awkwardly timed after memory stocks took the worst of Monday's selling — becomes the single most important datapoint for the chip complex this week.

Bobby Insight

Near-term pressure on semiconductors and rate-sensitive growth persists until the 10-year yield stabilizes below 5%, but this selloff is creating the entry points for the next leg higher.

The combination of $100 oil, a hawkish Fed path, and a 5.26% 10-year yield is a genuine headwind that buybacks alone cannot neutralize. However, the tariff de-escalation with China and Nvidia's willingness to deploy $235 billion signal that corporate fundamentals remain intact. If Friday's jobs report comes in soft, yields retreat and chips rally hard — position accordingly rather than chasing the panic.

What This Means for Me

means-for-me
If your portfolio leans toward growth and semiconductors, expect continued volatility this week — Micron's Wednesday earnings and Friday's jobs report are the two events that will set the tone. Bond holders should note that 5.26% on the 10-year is finally offering real income, making long-duration Treasuries genuinely competitive with equity risk for the first time in two decades. If you hold energy or commodities, the Iran standoff is a tailwind, but one that reverses instantly on any diplomatic breakthrough — treat oil strength as a trade, not a thesis.

Stock to Watch

StocksImpactAnalysis
NVDA
Positive
The $235 billion buyback authorization is the largest in U.S. corporate history and provides a powerful price floor, but it's fighting a sector-wide de-rating. Watch whether the relative strength holds if yields keep climbing.
AMD
Negative
Down 5.2% with no buyback cushion and direct exposure to AI accelerator demand. If OpenAI's training pause spreads to other labs, AMD's data-center growth narrative takes the hit first.
QCOM
Negative
Fell 5.7%, the second-worst in the group, despite limited direct AI-training exposure. This looks like beta-driven selling — which means it could snap back fastest if yields stabilize.
MU
Negative
Down 3.7% into Wednesday's earnings, with memory pricing directly tied to AI training demand. The report is now a binary event for the entire memory complex.
