مؤشر يضم 30 شركة أشباه موصلات مدرجة في الولايات المتحدة — إنفيديا وتي إس إم سي وبرودكوم وغيرها — وهو مقياس لدورة الرقائق وشهية المخاطرة في قطاع التقنية.
مؤشر فيلادلفيا لأشباه الموصلات (SOX) هو مؤشر قطاعي يتتبع 30 من أكبر شركات أشباه الموصلات المدرجة في الولايات المتحدة، بما في ذلك إنفيديا وتي إس إم سي وبرودكوم وAMD. ويُعد مقياسًا لدورة الرقائق وقطاع التقنية ككل.
The Philadelphia Semiconductor Index, known as the SOX, tracks 30 U.S.-listed companies engaged in the design, manufacture, and distribution of semiconductors. It was launched in 1993 on the Philadelphia Stock Exchange and is now administered by Nasdaq following its acquisition of the exchange. Members include global chip leaders such as Nvidia, Intel, and TSMC through its U.S. listing. It is the most widely cited equity benchmark for the semiconductor industry.
Because chips go into nearly every modern product, from phones to cars to data centers, the SOX is often read as a leading gauge of global manufacturing and technology demand. The semiconductor industry moves through pronounced boom-and-bust cycles driven by inventories and capital spending, and the SOX is used to judge where the chip cycle stands. Outperformance versus the Nasdaq is frequently taken as a signal that markets expect the chip cycle to improve. The index is highly volatile, so trends usually matter more than day-to-day swings.
The SOX responds to memory and foundry conditions, data-center and AI-related investment, smartphone and PC demand, and geopolitical factors such as U.S.-China technology restrictions. Capital-spending plans and inventory levels reported by major chipmakers can move the index sharply. Asian supply-chain data, such as Korean semiconductor exports and Taiwanese chipmaker revenues, provide useful confirmation of industry conditions. The Nasdaq Composite, global manufacturing PMIs, and earnings from leading chip companies are common cross-checks.
