# [Breaking News Analysis] Nvidia shares drop 9% in after-hours trading following reports of CEO's potential dismissal! What will happen to the Nikkei 225 at the 61,000 yen …
On the morning of November 12, 2026, news broke that shocked investors.
“Nvidia’s board of directors is preparing to dismiss CEO Jensen Huang”
This was reported by the American newspaper, The Wall Street Journal (WSJ).
Following this news, Nvidia’s stock fell nearly 9% in after-hours trading.
Meanwhile, the Nikkei 225 had risen for three consecutive days leading up to this, and it opened higher on the 12th as well, but this news caused it to temporarily fall into negative territory. It has since shown restless movement, attempting to recover.
In conclusion:
– The dismissal is currently at the stage of being a report that they are “preparing” for it; nothing has been decided yet.
– The issue is not about the company’s profits, but about the CEO’s personal conduct.
– Demand for AI itself remains strong, as seen in CoreWeave’s earnings from the previous day.
– However, for the Nikkei 225, there are many other factors to watch, such as the weak yen, interest rates, and the SQ.
That is the current situation.
In this article, I will summarize the following as simply as possible:
– What happened (the details of the news)
– How was the US market the previous day?
– The movement of the Nikkei 225 on the 12th
– Stocks likely to be affected in Japan
– Future scenarios and figures to watch
– How should beginners approach this?
I will summarize these as simply as possible.
* This article is based on information available as of approximately 11:30 AM (Japan Standard Time) on November 12, 2026. It does not include the closing price for the 12th. This is not a recommendation to buy or sell any specific products. Please invest at your own risk.
1. What happened? The details of the news
To summarize the content of the report simply:
– The WSJ reported that “Nvidia’s board of directors is preparing to dismiss CEO Huang”
– The reasons are two affairs involving Mr. Huang
– The first is a relationship with a woman suspected of having ties to Chinese intelligence agencies (Mr. Huang himself has admitted to the relationship)
– The second is a relationship with a vice president in the company’s healthcare division, as reported by The New York Times. This vice president is said to be a direct subordinate of Mr. Huang
The second point, in particular, is being perceived as an issue that calls into question his judgment as the head of the company.
In response to this, Nvidia’s public relations department commented:
“Jensen will continue to lead the company as CEO without interruption”
In other words, the company is currently denying the report.
However,
・Bloomberg reported that the company is “looking for a successor with an outside firm and is considering appointing an interim CEO.”
・There are also reports that some members of the board of directors are pushing for CFO (Chief Financial Officer) Colette Kress to serve as interim CEO.
・Analysts have also expressed concerns that “there is no succession plan, so dismissing the CEO immediately could cause chaos within the company.”
This has also emerged.
The important point is that this is at the stage of “being reported as preparing” rather than “the dismissal has been decided”. You need to be careful, as the way this is written varies depending on the article.
2. The previous day (November 11) in the US market was actually in great shape
In fact, until just before this news broke, US stocks were doing well.
Here are the results for the US market on November 11.
・S&P 500: 7,619.38 (+1.31%)
・Nasdaq Composite: 25,466.19 (+1.60%)
・Dow Jones: +0.49%
・Semiconductor stock index (SOX index): Over +5%
The reason for the rise was that the earnings of AI data center company CoreWeave were very good because of this. They also revised their sales outlook upward, and CoreWeave’s stock rose about 25% in a single day.
Nvidia also finished at $173.73, up 2.87%, during regular trading hours.
However, after trading ended, the WSJ report came out, and the stock plummeted in after-hours trading. It was, so to speak, a case of “cold water being poured on it right after it rose on good news.”
By the way, Nvidia’s stock had already fallen about 27% from its all-time high on October 6 ($239.24) as of the closing price on the 11th. There is a risk that this news will cause it to fall even further.
3. How did the Nikkei 225 move on the 12th?
Let’s look at the flow of the Nikkei 225 in chronological order.
・Closing price on the 11th: 61,248.59 yen (+789 yen, 3rd consecutive day of gains)
・It had risen over 3,800 yen in the three days leading up to the 11th
・Opening on the 12th: 61,475 yen (+226 yen), starting with a 4th consecutive day of gains
・Around 9:11 AM: 61,209 yen (-39 yen), briefly turning negative
・Around 10:00 AM: Recovered to 61,430 yen (+181 yen)
In other words,
“Started positive due to the rise in US semiconductors -> Sold off on Nvidia news -> Bought back again”
is the kind of up-and-down movement we are seeing.
During the same time period,
・Nasdaq futures were down about 1%
・Taiwanese and South Korean stocks also fell (South Korea turned negative)
・Oracle and CoreWeave, which are major Nvidia customers, also fell in after-hours trading
and the selling spread to semiconductor-related stocks in Asia as well.
4. Japanese stocks likely to be affected
Japanese stocks with deep ties to Nvidia are more susceptible to the impact of this news.
・Advantest: Deeply connected to Nvidia through its “test equipment” for AI semiconductors. A stock with a very large impact on the Nikkei 225
・Tokyo Electron: A major manufacturer of semiconductor production equipment
・SoftBank Group: Heavily invested in AI-related fields and easily swayed by the overall sentiment of AI stocks
These three have a large “weight” within the Nikkei 225, so the Nikkei 225 can move by several hundred yen just from the movement of these three stocks as well.
In fact, the rise on the 11th was driven by Advantest and Tokyo Electron alone, which pushed the Nikkei 225 up by about 512 yen. Because they were the stocks relied upon when the market rose, the impact will be significant when they fall.
5. Many other factors to watch besides Nvidia
The current market is not moving solely based on Nvidia news. There are other factors to keep an eye on.
① The yen is approaching 160 against the dollar
・The dollar-yen is around 159.70-80 yen
・As it nears 160 yen, there is caution regarding “currency intervention” (buying yen to stop the depreciation) by the Japanese government
・Vice Minister of Finance for International Affairs Mimura has also issued a warning, stating that “the movements of the past few days feel too fast”
A weak yen is a plus for export companies, but if intervention causes a sudden shift to a stronger yen, it can trigger a sell-off in stocks.
② Both the US and Japan are in a “rate hike” mood
・US consumer prices (CPI) in October were higher than expected
・A rate hike by the Fed (US central bank) in December is seen as almost certain (about 90% according to CME FedWatch)
・The yield on the US 10-year Treasury note is at a high level of about 4.99%
・The Bank of Japan is also expected to hike rates in December, with about 85% of the market pricing it in
When interest rates rise, it tends to be a headwind for stocks, especially high-tech stocks.
③ The 13th (Friday) is “SQ”
・November 13th is the SQ (Special Quotation) calculation date for options
・Market movements tend to be larger around the SQ date
・The US Producer Price Index (PPI) will also be announced on the night of the 13th
④ US earnings reports
・Earnings for Cisco and Applied Materials are scheduled
・Applied Materials, in particular, is a semiconductor equipment company, so it is likely to affect stocks like Tokyo Electron
6. Future scenarios
Depending on how the Nvidia news unfolds, three patterns can be considered.
Scenario A: Dismissal is officially decided
・In the short term, there is a possibility that Nvidia and semiconductor stocks will be sold off further.
・Especially if a successor remains undecided, the company’s future outlook becomes unclear, making it easier for selling pressure to intensify.
・In Japan, Advantest, Tokyo Electron, and SoftBank Group are likely to act as a drag on the market.
Scenario B: Mr. Huang’s continuation is confirmed
・There is a possibility that buybacks will occur as the market concludes that “the worst-case scenario has been avoided.”
・However, the affair issue itself remains, so things may not return to normal immediately.
Scenario C: Time passes without clarity
・An unsettled market will likely continue, with prices rising and falling every time new news emerges.
・With the addition of SQ and interest rate hike discussions, price movements are likely to become volatile.
What you should remember here is that this issue is not about “AI no longer selling.”.
Looking at CoreWeave’s earnings from the previous day, demand for AI remains strong. The issue is “who will be the head of the company,” so if the situation settles down and a new structure becomes visible over time, things may stabilize.
7. Numbers to watch on the Nikkei 225
I have summarized the numbers that are attracting attention in market analysis articles.
・Lower benchmark (weak if it breaks below this): 61,248 yen (closing price on the 11th)
・Upper benchmark 1: 62,019 yen (200-day moving average. The first hurdle is whether it can close above this)
・Upper benchmark 2: 63,000 yen (a round number)
・Upper benchmark 3: 64,831 yen (high on October 29th)
**”Whether it can close above 62,000 yen or break below 61,248 yen”** will likely be the turning point in the short term.
8. How should beginners approach this?
When such major news breaks, here is a summary of what I want beginners to keep in mind.
・”Reports” and “decisions” are different. Do not judge based on headlines alone.
・Price movements immediately after news tend to be large. Do not panic-buy or panic-sell.
・Do not focus too much on a single stock or a single theme (like AI only).
・If you are doing accumulation investing, the basic rule is to continue calmly even on days like this.
・Be aware that the week with SQ tends to have volatile price movements.
Stock prices can move significantly due to “people” issues like a CEO scandal. However, in the long run, what ultimately determines the stock price is how much profit the company makes.
If you develop the habit of thinking, “Is this related to the company’s earnings?” instead of being swayed too much by the news, you can avoid panicking.
Summary
・WSJ reported that “Nvidia’s board is preparing to dismiss CEO Huang.” Stock price fell nearly 9% in after-hours trading.
・The reason is two affair issues. The company denied it, saying “he will continue as CEO,” so it is not yet decided.
・The US market the previous day was in great shape due to CoreWeave’s strong earnings.
・The Nikkei 225 started with a 4-day winning streak on the 12th, then briefly turned negative, followed by a recovery.
・Pay attention to other factors such as the yen approaching 160, US-Japan interest rate hikes, and the SQ on the 13th.
・The turning point is “whether it can close above 62,000 yen or break below 61,248 yen.”
The market trend is likely to change significantly depending on how Nvidia’s board moves next. I will summarize again when follow-up reports come out.
