Nvidia's P/E is 22.6x, the lowest of its weekly readings in five years. AMD's EV/Sales is 18.4x, about the 90th percentile of its own five-year range. Broadcom's P/E of 40.8x sits below its five-year median of 46.1x. Those are the November 9 readings, from the day Nvidia fell more than 4% and the other two rose sharply. Same industry, same news, three very different starting points.
What happened to the three stocks
The facts below are as reported. The allegations about Nvidia's chief executive are not established, and the board's investigation is not complete. Our first piece on the Nvidia probe covers that story and Nvidia's own history.
- CNBC reported on November 10 that Nvidia shares fell 5.53% on Tuesday after closing more than 4% lower on Monday, as investors weighed the fallout from CEO Jensen Huang's affair with an alleged Chinese spy. (CNBC)
- In the same report, CNBC said some of Nvidia's chip rivals were seeing a boost. AMD gained 13% on Monday and Broadcom just over 10%. On Tuesday AMD was up another 1.3% and Broadcom nearly 4%.
- NBC News reported on November 10 that the move had erased almost $500 billion of Nvidia's value in two days, and that the shares were down 31% from their October 6 record high. It also reported that Nvidia's independent directors retained former acting U.S. Attorney Joon H. Kim and the law firm Wachtell, Lipton, Rosen & Katz to run the investigation. (NBC News)
- Tuesday was also the day of a hot inflation report. CNBC reported that October consumer prices rose 0.4% against a 0.3% forecast, that stocks fell and Treasury yields jumped. (CNBC) Tuesday's moves therefore mix at least two stories.
Where each one sits against its own history
We rank each stock's current multiple against its own weekly readings from the last five years. As of the November 9 close:
| Stock | Measure | Now | Five-year median | Rank in own range |
|---|---|---|---|---|
| Nvidia | P/E | 22.6x | 55.9x | Lowest reading |
| Nvidia | EV/Sales | 14.2x | 25.1x | 8th percentile |
| Nvidia | EV/EBITDA | 21.4x | 47.9x | Lowest reading |
| AMD | P/E | 110.6x | 108.2x | 52nd percentile |
| AMD | EV/Sales | 18.4x | 8.9x | 90th percentile |
| AMD | EV/EBITDA | 75.0x | 34.4x | 84th percentile |
| Broadcom | P/E | 40.8x | 46.1x | 44th percentile |
| Broadcom | EV/Sales | 17.9x | 17.4x | 54th percentile |
| Broadcom | EV/EBITDA | 31.0x | 37.5x | 40th percentile |
Three things stand out.
Nvidia is at the bottom of its range on every measure. Its P/E and EV/EBITDA are the lowest of roughly 260 weekly readings. A week earlier it was higher on all three.
AMD is near the top on sales and EBITDA. Its EV/Sales of 18.4x compares with a five-year median of 8.9x and a five-year high of 25.2x. Its P/E tells you little. Over the same window it ran from 23.6x to 1,611x, because earnings were thin for part of it, so a 52nd-percentile P/E is not a sign of a middling price. Only about 170 of its weekly readings also have a usable EV/EBITDA, so that rank rests on a shorter record.
Broadcom is in the middle. All three of its ranks fall between the 40th and 54th percentiles. Of the three, it is the one whose current price looks most like its own recent past.
What the rank does not tell you
Why the prices moved. CNBC reported that the rivals got a boost during Nvidia's turmoil. A valuation history cannot say whether that was money rotating out of Nvidia, a reaction to something specific to AMD and Broadcom, or the market on a day when all three were already volatile. Our weekly readings do not isolate the cause.
Whether a high or low rank persists. AMD's EV/Sales has been higher than it is now, and was 24.2x five weeks ago. Nvidia's has been lower, at 9.3x. A rank describes where the price sits relative to the past, not where it goes.
Forward earnings. Yahoo Finance's forward P/E snapshots put Nvidia near 13.3x, Broadcom near 16.6x and AMD near 30.0x. Those are single figures from one source, not ranked against any history and not our calculation. They rest on analyst estimates that can change quickly with news like this.
How long the story lasts. CNBC quoted Dan Ives of Yorkville Ives & Co saying a board investigation could take four to six weeks and weigh on the stock until more news emerges. That is one analyst's estimate.
How to use this today
We do not make buy or sell calls, and nothing here is a recommendation or a price prediction. The useful comparison is narrower. If you own more than one of these, the week showed they can move in opposite directions on the same day, so check how much of your portfolio each one is and whether the mix still matches what you intended before the news. If you are weighing one against another, put the multiples side by side with each one's own range, and look past the current price alone.
The AI infrastructure theme page ranks the group against each member's own history. You can check live readings on the pages for Nvidia, AMD and Broadcom. Our earlier Nvidia vs AMD comparison shows how far apart two chip makers can sit in their own ranges, and what a valuation percentile is explains how each rank above is built.
