Nvidia Slides 3.52% as SK Hynix's Record 15% Plunge Rattles Chip Stocks

Contagion Across the Chip Sector: Anatomy of a Red Session

The semiconductor sector had one of its roughest sessions of the summer yesterday. Nvidia (NVDA) closed down 3.52% at $203.53, on volume of 121.4 million shares. It wasn't an isolated move: Advanced Micro Devices dropped 4.2%, Intel fell 6.12%, Texas Instruments slid 3.93%, and the leveraged bearish ETF SOXS jumped 14.34%, reflecting a wave of selling and downside hedging that swept across the entire chip supply chain.

Context: The Story Starts in Seoul

The Debut That Lit the Fuse

On Friday, July 10, SK Hynix — the world's second-largest memory chipmaker — debuted on the Nasdaq through an ADR (American Depositary Receipt) offering priced at $149 per share, raising $26.5 billion to fund its capacity expansion. The listing was a resounding success: shares jumped 13% on their first day of US trading, riding a wave of investor appetite for anything tied to memory and AI infrastructure.

Monday's Whiplash

But on Monday, July 13, the euphoria reversed sharply: SK Hynix plunged 15.4% in Seoul, its worst session on record. According to Bloomberg and CNBC, the move combined profit-taking after the debut pop with uncertainty over how the US-listed shares should be valued relative to the Korean stock, since the ADR effectively created a new valuation benchmark for the company.

Domino Effect

The shockwave hit Wall Street immediately. According to Yahoo Finance, Micron Technology fell nearly 6% in premarket trading, alongside Western Digital, Seagate Technology, and SanDisk. Among the major AI chip designers, Nvidia, AMD, Broadcom, and Qualcomm all traded lower, while equipment makers — Applied Materials, Lam Research, and KLA — each lost around 3%. ASML slipped ahead of its earnings report, and Taiwan Semiconductor Manufacturing (TSM) also gave up ground ahead of its own quarterly results.

Some names faced additional, company-specific pressure: Texas Instruments fell 3.93% on weaker-than-expected industrial and automotive demand amid prolonged inventory digestion, while ASE Technology Holding dropped 5.13% on cooling consumer electronics demand and rising material costs.

Technical Picture: RSI in Neutral Territory

Nvidia's 14-day RSI stood at 49.92 at Monday's close, down from 57.00 the previous Friday. The indicator has moved from mildly bullish to neutral territory, without yet entering oversold conditions (below 30). That suggests that despite the sharpness of the decline, the market isn't (yet) pricing in technical panic on the stock — this looks more like an orderly correction within a range.

Volume Analysis

The most telling data point of the session is the behavior of SOXS, the 3x leveraged bearish semiconductor ETF: it jumped 14.34% to $4.665, on volume of 598.9 million shares — one of the highest of any ticker in the market that day. This points to:

1. Active bearish positioning: this wasn't just organic selling, but a meaningful volume of hedges and directional downside bets
2. Conviction behind the move: Nvidia's volume (121.4 million shares) was clearly above normal session levels, a sign of institutional participation
3. A sector-wide event, not an isolated blip: the breadth of the move — memory, design, and equipment names all affected — points to a sector-wide recalibration rather than a single-company problem

Market Sentiment

News flow around Nvidia remains mostly neutral-to-moderately-bullish over the medium term — MarketBeat noted the company reported 85.2% year-over-year revenue growth and approved an $80 billion share buyback program — suggesting the session's decline is more of a tactical reset tied to SK Hynix noise than a shift in the underlying AI demand thesis. Still, some coverage flagged caution: Texas Instruments drew clearly bearish sentiment over its industrial demand woes, a reminder that not every corner of the chip sector moves in lockstep with AI.

Levels and Keys to Watch

1. $200 on Nvidia: a round psychological level just below the close; losing it on volume would open the door to testing deeper support
2. SK Hynix's price action in Seoul: until it stabilizes, it will remain the source of imported volatility for the rest of the sector
3. TSM and ASML earnings: their quarterly reports, with commentary on CoWoS packaging capacity and equipment demand, will be the next real catalyst for the sector
4. RSI below 30: if reached, this would mark a technically oversold zone that has historically preceded rebounds in quality names like Nvidia

Implications for Investors

For those already holding exposure to the sector, this episode is a reminder that idiosyncratic events — like a single stock's debut in a new market — can generate imported volatility that has little to do with the fundamentals of the companies caught in the crossfire. Separating SK Hynix's technical noise from the long-term AI demand thesis is key to avoiding overreaction.

For those weighing an entry, the combination of a double-digit jump in leveraged-bearish SOXS alongside an RSI still in neutral territory suggests the market is digesting the move rather than capitulating. Prudence argues for waiting for confirmation — either stabilization in Seoul or the upcoming TSM results — before treating the pullback as a buying opportunity.

Conclusion

The July 13 session offers a clear lesson: in a sector as interconnected as semiconductors, volatility from a single listing — in this case, SK Hynix's post-debut adjustment in Seoul — can drag down the biggest AI names within hours, with Nvidia falling 3.52% despite fundamentals that, for now, haven't changed. A neutral RSI and heavy bearish positioning via SOXS point to a short-term correction rather than a cycle shift, but TSM and ASML's upcoming earnings will be the real test of whether AI demand still supports the sector's narrative.
