Semiconductor index nears bear market as chip selloff deepens

The Philadelphia Semiconductor Index fell below the closely watched 12,000 level on Thursday, closing at approximately 11,841 — a decline of about 4.5% on the day — as the chip selloff that has gripped markets for weeks accelerated into what analysts warn could become a full bear market.marketwatch+1

The index is now roughly 19% below its record closing high set on June 22, according to MarketWatch, which identified a close at or below 11,707.78 as the threshold that would officially mark a 20% drawdown from the peak — the standard definition of a bear market. On Friday morning, Bloomberg reported that U.S. stock futures were sliding further, with the SOX "on the cusp of a bear market and set to extend Thursday's losses."bloomberg+1

A Rotation Away from AI Winners

The selloff marks a sharp reversal for chip stocks, which had more than doubled between late March and mid-June on the back of soaring AI-related demand. Yahoo Finance's Jared Blikre noted that many of the index's 30 components have fallen 25–30% over the past 10 trading days, describing the price action as a "head and shoulders top" that could signal further downside if buyers fail to reclaim the 12,000 level.investopedia+1

SK Hynix, which debuted its American Depositary Receipts on the Nasdaq ↘ 0.37% on July 10, has been a flashpoint for the selloff. After surging 13% on its first day, the ADR fell 9.6% the following session and continued to decline, while shares in Seoul posted a record 15% single-day drop. Memory chipmakers more broadly have borne the brunt of the selling, with Yahoo Finance data showing the Roundhill Memory ETF already in bear-market territory.finance.yahoo+3

Mechanics of the Decline

Analysts have pointed to several forces amplifying what might otherwise be an orderly profit-taking episode. Reuters reported that hedge funds sold chip stocks for a fourth consecutive week heading into July. The proliferation of leveraged ETFs tied to individual semiconductor names — particularly in South Korea, where retail-driven leveraged funds ballooned to roughly $9 billion in assets — has created a mechanical feedback loop in which falling prices trigger forced rebalancing sales.finance.yahoo+2

Investing.com analysis noted that the semiconductor trade became "so popular and so heavily leveraged, that when sentiment turns even slightly, forced selling takes over," making normal pullbacks look far more alarming than fundamentals warrant.investing

What Comes Next

Markets are now looking ahead to the next round of big tech earnings from Alphabet ↗ 0.95%, Microsoft ↘ 0.71%, Meta ↘ 1.31%, and Amazon Amazon.com, Inc. ↘ 1.82% for clarity on whether AI capital expenditure growth remains intact. Contracts on the Nasdaq 100 were down 1.9% in early Friday premarket trading, while S&P 500 futures fell 0.9%, with Nvidia ↘ 3.55% leading the Magnificent Seven lower.marketwise+1

"If we close underneath 12,000 today and then Friday or Monday we pop back up above strongly, that would suggest that's a false breakdown," said Yahoo Finance's Blikre on Thursday. "But that's getting a little bit ahead of the trade right now."finance.yahoo
