Riding the hardware wave

TTM Technologies (NASDAQ:TTMI) jumped on Monday, November 9, 2026, appearing among the bigger mid-cap gainers. The S&P MidCap 400 member climbed as investors rushed back into the companies that Supply the physical components behind artificial intelligence computing.

No company-specific news was found to explain the move. TTM appeared to trade with its sector, and the sector was having one of its best days in months.

What TTM makes

TTM is one of the largest makers of printed circuit boards in North America, along with radio frequency components and other engineered products. Its boards end up in data-center servers and networking gear, as well as aerospace and defense systems, cars and medical devices.

The data-center Business has become a bigger part of the story as AI servers Demand more advanced, multilayer boards that can handle high speeds and heavy power loads. That has tied TTM's share price closely to sentiment around AI infrastructure spending, which swung sharply over the past week. When investors fear a slowdown in AI spending, component suppliers tend to sell off hard; when that fear lifts, they can rebound just as quickly, as Monday showed.

A violent Reversal in chips

The prior week had been punishing. After the November 3 midterm elections, investors worried that Democratic wins could bring restrictions on data centers, according to news reports. On Thursday, November 5, the PHLX Semiconductor index tumbled, and the Nasdaq slid into correction territory, according to market coverage.

Monday reversed much of that pain. The semiconductor index rallied to 10,033.93, its best day since July 30, according to market reports. Advanced Micro Devices (NASDAQ:AMD) soared after Oppenheimer upgraded it to Outperform with a $600 target, and Applied Materials (NASDAQ:AMAT) and Lam Research (NASDAQ:LRCX) posted big gains.

Hardware suppliers closer to TTM joined in. Amphenol (NYSE:APH) and Dell Technologies (NYSE:DELL) both closed higher, according to market data, while Flex (NASDAQ:FLEX) jumped. Fellow electronics manufacturer Sanmina (NASDAQ:SANM) soared after the bell on Blowout results, a reminder of how strong AI hardware demand has been.

Not every chip name joined

The rally had one notable exception. Nvidia (NASDAQ:NVDA) was the only decliner in the semiconductor index, according to news reports, as an independent review by Nvidia's board involving CEO Jensen Huang weighed on the stock. The board said it has "no reason to believe" national security or company secrets were compromised, according to market coverage.

The broader market roared regardless. The S&P 500 jumped 173.08 points to 7,549.94, its best day since April 8, and the S&P MidCap 400 finished at 3,715.23. Brent Crude fell $5.75 to $92.57 a barrel on hopes of progress in US-Iran talks, easing Inflation worries.

A strategist framed the recent turmoil, according to market reports: "we see this more as an intra-cycle reset and another deleveraging event in the AI supercycle."

AI Hardware Demand Signals

For TTM, the next signals will come from the big AI spending reports. Nvidia reports on November 17, and Earnings this week from Applied Materials and Cisco (NASDAQ:CSCO) will offer clues on demand for data-center hardware.

Political noise around data centers is another wild card, given the worries that hit the group after the midterms. Any proposals from the incoming Congress on data-center permits or power costs could quickly change the mood. On the macro side, October's Consumer Price Index arrives Tuesday, the last inflation report before the Federal Reserve's December 8-9 meeting, where traders see a rate hike as likely.
