Philadelphia Semiconductor Index opens 4% higher as chip stocks rally

The Philadelphia Semiconductor Index opened 4% higher Tuesday as chip stocks rallied after oil prices plunged and Middle East tensions eased.

Bernstein's Varun Govindaraj, senior analyst, maintained his buy rating on Nvidia in a note to clients Monday, predicting the stock could breach $300 next and urging institutional investors to accumulate shares. The firm set a price target of $315, implying roughly 53 percent upside from Nvidia's close near $206.

The advance was broad-based. Micron jumped 4.8 percent, AMD gained 4.91 percent, Broadcom rose 2.97 percent, ASML added 3.62 percent, TSMC climbed 2.24 percent and Nvidia advanced 1.9 percent. The move extends a rebound after the index fell for five consecutive sessions following Alphabet's earnings, then bounced 8.2 percent on July 30.

The rally comes as the broader market approaches records. The Dow closed at an all-time high of 53,178.41 on Monday, while the S&P 500 rose 1.48 percent and the Nasdaq gained 2.13 percent. Nvidia, which reports earnings Aug. 26, is the next major catalyst for the sector.

Traders pointed to three catalysts for the chip rally: President Donald Trump's decision over the weekend to cancel large-scale airstrikes on Iranian energy facilities, which sent WTI crude down 5.11 percent to $80.34 a barrel; strong Big Tech earnings from Palantir, Amazon, Microsoft and Meta; and a rebound in the Nasdaq-100, which had fallen 11.3 percent between June 2 and July 29.

The drop in oil eased inflation concerns, sending the 10-year Treasury yield down 6.1 basis points to 4.68 percent. The dollar index slipped 0.003 points to 99.936. Microsoft, Nvidia, Amazon and Meta added about $537 billion in combined market value on Monday.

The semiconductor sector has been volatile this year. Nvidia, the world's leading GPU maker, has hovered around the $190 to $215 zone for most of 2026, opening August at $200 before climbing to $206 on Monday. Cathie Wood's Ark funds bought 73,166 Nvidia shares on July 28, valued at about $14.3 million, according to Ark's daily trade information.

Nvidia's forward price-to-earnings ratio of 17.53 is its lowest since April 2015, according to Barron's, even as the company faces risks including heavy dependence on a small group of hyperscaler customers, which account for 54 percent of revenue.

The rebound in chip stocks comes after a sharp correction. The Nasdaq-100 declined 11.3 percent between June 2 and July 29, a move CFRA Research expects the index to recoup within two months before rising another 6 percent. Big Tech capital spending on AI infrastructure remains a key driver, with Microsoft, Meta and Alphabet all raising or holding their fiscal 2026 capex outlooks in recent earnings.

The strength in semiconductors shows investors rotating back into the AI trade after a volatile stretch, even as questions persist about whether hyperscaler spending can sustain the sector's growth. With Nvidia's earnings due Aug. 26 and the Federal Reserve's policy path in focus, chip stocks remain the highest-beta bet on the AI infrastructure buildout.
