Chip stock rally returns as US-Iran diplomacy and falling oil prices reshape market sentiment
The Philadelphia Semiconductor Index crossed 14,000 for the first time as two geopolitical shifts reignited investor appetite for semiconductor plays
Chip stocks surged to a record on June 15 as optimism around a preliminary US Iran agreement sent oil prices lower and pulled investors back into risk assets.
The Philadelphia Semiconductor Index, known as the SOX, rose more than 4% and broke above 14,000 for the first time.
The rally helped lift the broader US market, with the Dow Jones Industrial Average touching a record intraday high while the S&P 500 and Nasdaq also advanced.
The trigger was geopolitical relief. A preliminary agreement between the US and Iran raised hopes that the conflict could move toward a ceasefire and eventually reopen the Strait of Hormuz, one of the world’s most important oil chokepoints.
Oil prices fell sharply on the news. Brent crude dropped about 5% to below $83 a barrel, its lowest level in three months, easing concerns that energy costs would keep inflation pressure elevated.
Semiconductors were among the biggest winners. Micron rose more than 9%, AMD jumped more than 7%, and Nvidia added about 3% as investors returned to AI linked stocks.
The chip rally already had momentum before the latest geopolitical turn. The SOX has surged this year as hyperscalers including Microsoft, Amazon, Google, and Meta keep pouring capital into AI data centers, memory, networking, and advanced chips.
