Qnity Is Added to the PHLX Semiconductor Index. Why the Stock Is Down.

Coming into Tuesday’s trading, Qnity stock was up almost 50% this year. Still, shares were well off from their 52-week high of $177.28. (NYSE)

Key Points

• Qnity Electronics was added to the Philadelphia Semiconductor Index on Monday.
• Qnity shares fell in premarket trading Tuesday, missing out on a typical indexation boost.
• All nine Wall Street analysts covering Qnity rate the stock a Buy, with an average price target of about $180.

Qnity Electronics was added to the Philadelphia Semiconductor Index on Monday.

Investors generally like it when their companies are added to indexes. Qnity stock, however, isn’t getting a boost.

Shares of the semiconductor materials supplier were down 0.2% in premarket trading Tuesday at $121.53, while S&P 500 and Dow Jones Industrial Average futures were up 0.1% and 0.3%, respectively.

To be sure, indexation is a positive. It can mean increased demand for shares from passively managed funds that track the index. (More demand with fixed supply can increase the price of anything, including stocks.)

Only tens of billions of dollars are linked to the index, however. That isn’t all that much. For comparison, trillions are indexed to the S&P 500. (Qnity is in the S&P 500.)

Coming into Tuesday’s trading, the Philly Sox index, as it is sometimes referred to, was up about 100% over the past 12 months, according to FactSet. Many chip stocks have soared on higher demand linked to AI computing.

Qnity doesn’t make semiconductors. It makes materials that semiconductors need to make semiconductors. Other industry suppliers such as Entegris and KLA are included, though.

Qnity spun off from DuPont de Nemours on Nov. 1, 2025. Shares were trading at roughly $100 at the time of the spin. They traded above $175 in June before selling off, along with much of the tech sector, amid rising AI fears. The AI trade has come back, with the Nasdaq Composite closing at a record high on Monday.

Qnity has been a laggard, though. Shares are off roughly 30% from recent highs. That mirrors the semiconductor index’s performance. Investors have focused on some other technology stocks in the recent run.

Wall Street sees opportunity. Nine analysts cover the shares. All nine, or 100%, rate them Buy, according to FactSet. The average Buy-rating ratio for S&P 500 stocks typically ranges from 55% to 60%. The average analyst price target for Qnity shares is about $180.
