AMD Surges 11% on November 6: A Bottom Signal for AI Chip Stocks? What Drove the Nasdaq Rebound and What’s Ahead

On November 6, 2026 (local time), AI chip stocks rebounded across the U.S. market, partially easing the impact of the previous day's sharp drop. AMD surged 11.04%, while the Philadelphia Semiconductor Index rose 4.21%.The market recouped some of the previous day's steep losses.

​

As Nvidia, Micron, and TSMC also rose, hopes emerged that AI chip stocks may have found a bottom.

However, the move could also be viewed as a technical rebound following a sharp decline. It is still too early to conclude that the market has returned to an upward trend.

The tech-heavy Nasdaq rose, but the Dow fell. Rather than a broad market rally, buying may have concentrated in semiconductor stocks, which had previously suffered steeper losses.

Among the stocks leading the semiconductor rebound, AMD stood out the most.

After plunging about 17% the previous day, AMD rebounded by more than 11% as bargain hunters stepped in.

Earnings growth is also cited as a factor supporting investor sentiment. AMD's revenue in the third quarter of 2026 was about $13.38 billion, up 44.7% year over year, while data center revenue grew about 97%.

​

Continued demand for AI accelerators and server CPUs alsoappears to have supported investor expectations.

Key companies across the AI semiconductor supply chain also rose. Nvidia supplies AI GPUs, Micron produces memory such as HBM, and TSMC handles contract manufacturing of advanced semiconductors.

​

The simultaneous gains in these stocks can be interpreted as buying spreading across the AI infrastructure supply chain.

On November 5, the Philadelphia Semiconductor Index plunged about 12.25%. Concerns that regulations on AI data center construction could tighten after the U.S. midterm elections were cited as a key factor.

​

Following the Democrats' election victory, concerns arose over data centers' electricity and water use, environmental regulations, and permits for new facilities, increasing uncertainty around the expansion of AI capital investment.

​

The next day, November 6, semiconductor stocks rebounded as the view spread that the previous day's sell-off had been excessive.

However, keep in mind that a 4.21% gain in one day does not make up for the previous day's loss of more than 12%.

For example, if the index falls 12.25% and then rebounds 4.21%, it remains about 8.56% below its starting point.

​

Therefore, this rally recovered only part of the losses; it does not mean that uncertainty about the semiconductor industry outlook or policy has disappeared.

Even on the day semiconductor stocks rebounded, U.S. markets were mixed. Stronger-than-expected jobs data drew attention as a factor that could increase interest rate pressures.

​

U.S. nonfarm payrolls increased by 165,000 in October, and the unemployment rate fell to 4.1%.

Solid employment is positive for the economy, but it could also increase the likelihood of the Federal Reserve (Fed) raising interest rates.

​

Markets are watching the possibility of an interest rate hike in December. However, the actual decision may depend on upcoming inflation and employment data.

​

When interest rates rise, the discount rate used to convert future earnings into present value also increases, which can weigh on high-valuation growth stocks.

​

AI semiconductor companies in particular have high growth expectations reflected in their stock prices, making them relatively sensitive to both earnings growth and interest rate changes.

So, have AMD, Nvidia, and Micron already hit bottom?

What we can confirm at this point is that a short-term rebound has occurred, but it is difficult to say definitively that a medium- or long-term bottom has formed.

​

The Nasdaq rose on November 6, but was down about 3.4% for the week, marking its fourth consecutive weekly decline.

To assess whether the rebound will continue, it is worth watching three things.

First, determine whether discussions of U.S. AI data center regulations actually lead companies to scale back investment.

Second, watch whether demand for AI accelerators from Nvidia and AMD, and Micron's HBM supply expansion, translate into sustained earnings growth.

Third, assess how U.S. Treasury yields and changes in Federal Reserve monetary policy affect technology stock valuations.

​

In the South Korean market, Samsung Electronics and SK Hynix's HBM competitiveness, as well as foreign investors' trading activity, are also key areas to watch.

​

In summary, the sharp rise in semiconductor stocks on November 6 may signal a recovery in investor sentiment, but it cannot be conclusively called a signal of a trend reversal.

​

If further gains in the semiconductor index, corporate earnings, and continued data center investment are confirmed together, market confidence in a bottom forming could also increase.
