NVDA, AMD Chip Rout: Cramer Flags 'Monstrous' Margin Sellers

Jim Cramer warned that intraday reversals in semiconductor stocks are difficult to arrest when leveraged holders are forced to exit, as Nvidia fell 4.9%, AMD dropped 8.3%, and the SMH ETF slid 4.1% on July 27.

Chip stocks posted some of their steepest single-session losses in weeks on July 27, 2026, as Nvidia (NVDA) fell 4.9% to close at $196.51, Advanced Micro Devices (AMD) tumbled 8.3%, and the VanEck Semiconductor ETF (SMH) lost 4.1%. The move knocked Apple past Nvidia as the world's most valuable publicly traded company. CNBC host Jim Cramer captured the dynamic in a post on X: "When you have reversals like you have in the semis this morning, it is very difficult to reverse the downturn intraday as the sellers tend to be monstrous, motivated and often margined. So they have to get out."

What Happened

Monday's semiconductor selloff carried the hallmark of forced, not discretionary, selling. Chip stocks had been carried to elevated valuations by a concentrated group of leveraged investors. Once the complex began to roll, margin call desk activity accelerated the decline: positions built on borrowed capital must be unwound quickly to meet collateral demands, regardless of the seller's longer-term conviction.

The red stock chart pattern across the sector reflected this dynamic — sharp morning drops that found little intraday relief. Nvidia's five-year return stood at roughly 961% heading into the session, and AMD had rallied into all-time high territory in the first half of 2026, leaving both names vulnerable to rapid profit monetization under margin pressure.

Beyond NVDA and AMD, the damage spread across the supply chain. SK Hynix fell more than 7%, Micron Technology (MU) dropped more than 2%, and ASML also sold off. Intel (INTC) shed 3.5%. The Philadelphia Semiconductor Index (SOX), which had gained approximately 65% in the first half of 2026, extended a correction that began in early July.

The Circular-Financing Catalyst

The immediate fundamental trigger was a set of reports indicating Nvidia is in negotiations to backstop $250 billion in financing to support OpenAI's lease of computing power for a U.S. data center project. The arrangement raised alarms about circular financing — a structure in which suppliers become significant investors in their own customers, concentrating credit risk in the system. Nvidia's five-year debt-protection costs surged to record levels on Monday, a signal that institutional counterparties are pricing meaningful new tail risk.

Separately, Nvidia announced a strategic collaboration with SK Group — the parent of SK Hynix — covering a $500 billion-plus joint initiative spanning AI factories and next-generation memory development. While constructive for the long-term AI infrastructure thesis, the scale of announced commitments added to investor uncertainty about capital discipline and return timelines across the complex.

AI Overcapacity and Competitive Pressure

Broadening the structural pressure, Alphabet's shares dropped after the company announced further increases in capital expenditure during the latest earnings period, reinforcing concerns that return on AI infrastructure investment remains unproven at current spending levels. The question of when, and at what magnitude, AI capex translates to revenue has become the central debate for the sector.

Compounding the picture, a Chinese state-backed enterprise began mass production of critical semiconductor manufacturing equipment, intensifying pressure on equipment makers and narrowing the technology moat that U.S. and allied chip companies have maintained.

Market Reaction and Broader Context

Despite the severity of Monday's moves, retail sentiment data showed AMD posting an 82 (Very Bullish) score on social platforms and NVDA holding a 62 (Bullish) reading, suggesting individual investors are not yet capitulating. Institutional positioning told a different story, with hedging activity in listed options markets rising through the session.

Cramer himself, speaking on earlier broadcasts, had identified Micron, Applied Materials, and either Intel or AMD as preferred semiconductor exposures following the sector's earlier AI-driven selloff in late June — underscoring that his July 27 commentary was a near-term mechanical observation, not a reversal of longer-term thesis.

What Comes Next

The calendar provides clarity tests in the days immediately ahead. Microsoft, Amazon, and Meta are all scheduled to report earnings this week, with markets anticipating further announcements of AI infrastructure spending commitments. Any upside surprise on AI-related revenue or guidance could stabilize sentiment; a cautious capex tone from hyperscalers would likely extend the correction.

SK Hynix's next earnings report and ASML's order book data — a leading indicator of chipmaker capital spending — also carry significant weight for the sector's near-term direction.

Outlook

The July 27 semiconductor selloff bears the signature of leverage unwinding rather than a fundamental deterioration: chip stocks arrived at session open carrying both large gains and large margin exposure, and forced liquidation among chip sellers did the rest. The structural case — anchored in AI infrastructure spending, advanced memory demand, and sovereign chip investment programs — remains intact. Near-term risk is concentrated in the circular-financing overhang around Nvidia, in hyperscaler earnings guidance this week, and in the pace of Chinese chipmaking competition. Until margin positions are cleared, momentum reversals in the sector will remain difficult to arrest intraday.
