NVIDIA fell sharply when Jensen Huang resigned over a personal scandal. We looked at 26 past cases where a CEO or founder was hit by personal-conduct news or left suddenly, and asked what the stock did next against the S&P 500.
Short answer: history does not support "buy the drop" as a rule here. When a hired CEO left over a scandal, the next year was close to a coin flip. When the departing leader was the founder or the dominant figure, all five stocks lagged the S&P 500 over the next year, by 21 to 46 points. The samples are small, and the cases were picked by hand.
Jensen Huang resigned as CEO on 12 November 2026, effective immediately. This followed reports of a relationship with a suspected Chinese intelligence asset, then a report of a relationship with an executive who reported to him. The board named CFO Colette Kress interim CEO, and reportedly there was no formal succession plan. JPMorgan said the risk of tighter limits on chip shipments into China has risen. Earnings are due 17 November.
NVDA opened 12% to 14% lower, depending on the report, and was trading at $164.34 at 2 p.m. New York time, down about 5% on the day. That is 20% below its 3 November close, while the semiconductor ETF (SMH) is down about 4% over the same days. The market is treating this as an NVIDIA-specific loss. Losing a 33-year founder with no successor is a business question, even though the trigger was personal.
When the leader stayed, 4 of 6 stocks were ahead of SPY at three months (median +11.2 points), but the gain did not reliably last a year. In 24 of 26 cases the stock fell at some point in the next three months, typically by about 10% against its market.
The "shock" is the two trading days around the news, so after-hours announcements are caught. Later returns run from the end of those two days. "vs SPY" is the stock's return minus SPY's, in percentage points. Returns include dividends.
| Case | Shock | SPY | 3 mo | SPY 3 mo | vs SPY | 1 yr | SPY 1 yr | vs SPY, 1 yr |
|---|
¹ US-listed shares (ADRs), in dollars. ² Home-market listing in its local currency (yen, Swiss francs, won), so "vs SPY" includes currency moves and the home market's own performance. Against their own markets, Nissan was −34 and BP −33 over the year, so part of their lag is the UK and Japanese markets trailing the US.
To see whether the pattern holds outside hand-picked cases, we took 48 large US companies from 2010 to 2026 and found every day a stock lagged the S&P 500 by 7% or more, counting at most one drop per stock in any 30 days. We split the drops by whether they came within three days of an earnings report, a rough stand-in for business news. "Normal" is the same stocks on any ordinary day, which corrects for the list being mostly today's winners.
| Median return vs S&P 500 | 1 month | 3 months | 1 year |
|---|---|---|---|
| Drop with no earnings report (n = 213) | +0.6 | +1.8 | +8.3 |
| Normal days, same stocks | +0.4 | +1.3 | +5.2 |
| Drop on earnings (n = 276) | −0.9 | −0.4 | +4.2 |
| Normal days, same stocks | +0.3 | +1.0 | +4.2 |
Drops on earnings news tend to keep drifting down for about a month. Drops without earnings news recover slightly better than normal. That matches published research (Chan 2003; Savor 2012): price shocks that carry information persist, ones without information partly reverse. The gap is small, about half a point at three months and three points at a year, and the averages look much better than the medians only because of a few huge winners such as Tesla and AMD.
The useful question is narrower than "is this a bargain": does Huang leaving change whether NVIDIA's chips stay the default for AI? The next real evidence is the 17 November report and its guidance, then who is named CEO and whether China export rules tighten. Waiting for that costs relatively little: after the CEO cases above, the stock's worst point in the following month averaged about −7%.
