Just one week ago, Nvidia became the world’s most valuable company.
The chipmaker – whose shares had risen nine-fold since the end of 2022 – overtook Microsoft as its stock market valuation reached $3.34trn (£2.63bn).
Since then, the shares have fallen by 13%, declining in each of the last three trading sessions.
That has been enough to clip more than $500bn (£394bn) from Nvidia’s stock market valuation reached when, last Thursday, the shares hit an all-time intra-day high of $140.76 (£110.94) each (taking into account the 10-for-one share split completed earlier this month).
To put that into context, Exxon Mobil – the 14th biggest company in the S&P 500 index and itself one of only a dozen companies ever to achieve the status of the world’s most valuable company – has a stock market valuation of $511bn.
So what is going on?
There are a number of factors at play.
The first is profit-taking. Nvidia shares, prior to last Thursday, had enjoyed a fantastic run and had attracted a lot of hot money from so-called “momentum buyers” who see a stock moving higher and jump on board to profit from the ride.

It was natural for such buyers to lock in profits by selling.
Added to that is that speculative money has moved on. A report published over the weekend in the Wall Street Journal that Meta Platforms, the parent of Facebook, has held talks with Apple about integrating Meta’s generative AI model into the recently unveiled Apple Intelligence system sent shares in both higher as profits from Nvidia’s recent strong run were recycled.

Last week: Nvidia overtakes Microsoft
That money has not left the market – it has simply been redeployed from Nvidia to other stocks, not least Meta and Apple, but also elsewhere.
That can be shown by the fact that the sell-off in Nvidia, while also dragging down peers such as Broadcom, Taiwan Semiconductor, and Super Micro Computer (a server maker which is a heavy buyer of Nvidia’s chips), did not lead to a wider sell-off.
The Dow Jones, admittedly not as good a barometer of the US stock market as the S&P 500, hit its highest level for a month on Monday even as the S&P 500 and Nasdaq, both of which have a heavier weighting in Nvidia, were falling.
Also contributing to the sell-off was the revelation – via a filing to the main US financial regulator, the Securities & Exchange Commission – that Jensen Huang, Nvidia’s founder and chief executive, has taken advantage of the recent rise in the share price to reduce his holding.
Mr Huang, who founded Nvidia in 1993, sold just under $95m (£74.9m) worth of shares between Thursday 13 June and Friday 21 June. Nor is Mr Huang – who still owns more than 866 million shares in Nvidia worth $102.3bn (£80.3bn) at Monday evening’s closing price – the only director to have been selling recently.

Mark Stevens, a veteran venture capitalist who has been on the Nvidia board since 2008, has offloaded $28m (£22m) worth of shares this month while Tench Coxe, another VC who was one of Mr Huang’s earliest backers and who has been on the board since the start, has sold $119.5m (£94.1m) worth.
Selling by directors is not always a reliable guide to a company’s prospects. Sometimes it reflects personal factors, such as a divorce or estate planning, rather than indicating what a director thinks of a company’s prospects. Rightly or wrongly, though, it is usually taken as a negative signal.
Perhaps the most significant factor in the sell-off, though, is that some investors have been looking at Nvidia through traditional investment yardsticks.
The main one of these is the price/earnings (P/E) ratio. The higher the P/E ratio is, the more expensively a stock is valued.
Last week, after its latest gains, shares of Nvidia were changing hands at 45 times expected earnings.
To put that in context, the forward P/E of the S&P 500 is 22 times and the Nasdaq only slightly more. Put another way, investors were ascribing more than twice the value to Nvidia’s future earnings as they were to those of its peers.
Moreover, as the influential investment magazine Barron’s pointed out at the weekend, Nvidia was being valued at some 20 times its expected sales for the year to the end of January 2026 – a racy valuation, to say the least.

Stocks with those kinds of valuation have to justify it with spectacular earnings growth.
Yet, as Barron’s columnist Eric Savitz pointed out, Nvidia’s quarter-on-quarter earnings growth has, over the last four quarters, slowed from 88% to 34% to 22% to 18%. Now, quarter-on-quarter earnings growth of 18% is still pretty spectacular. But it does not quite justify a price/earnings multiple that has gone from 25 to 45 over the last year.
Pointing out that from 1976 to 2020, stocks trading at P/E rations of over 15 tended to underperform, Mr Savitz added: “I know what you’re thinking. It’s different this time. This is AI! And sure, maybe AI really is the most important thing to happen in technology since cloud computing, or the internet, or mobile phones, or even the personal computer. But the numbers worry me.
“Nvidia’s market value is now nearly five times the industry estimate for next year’s global chip sales-yes, the total from every company worldwide. Microsoft has seven times the number of employees Nvidia does, and twice the sales. Apple has five times the staff, and triple the sales volume. Nonetheless, this past week, Nvidia’s market cap vaulted past them both.”
Mr Savitz was not the only investment columnist suggesting that, perhaps, Nvidia’s shares might be over-valued.
Some of Monday’s sell-off was also fuelled by the highly influential ‘Heard on the Street’ column in the Wall Street Journal which, at the weekend, invited readers to cast their minds back to the dot-com bubble at the beginning of the century and, in particular, to the gyrations seen at that time in shares of Cisco Systems.
Cisco, the Journal reminded its readers, was favoured along with stocks such as IBM, Lucent and Intel – companies whose hardware were at the forefront of connecting households and businesses to the internet. By the end of 1999, it had become the world’s most valuable company.
The comparison with Cisco has undoubtedly dented sentiment towards Nvidia in some quarters.
Pointing out that today Cisco is now valued at 40% less than it was back then, the Journal highlighted that, at its peak in March 2000, Cisco shares were valued at 131 times forward earnings despite a less impressive financial performance than that recently shown by Nvidia.
Stressing that Nvidia was not is frothily valued as Cisco had been, the column added: “That doesn’t necessarily make Nvidia’s shares safe at their current level, though.
“The stock has seen a big influx of individual investors since the company’s latest financial results last month. Daily retail inflow has averaged nearly $141m since the earnings compared with a daily average of about $39m during the month prior, according to Vanda Research.
“Sell-side analysts are also getting rather exuberant. Several have pushed up their price targets since the stock’s 10 June split. And at least four of those targets are now at $160 and higher, which would put Nvidia’s market capitalization near $4trn at its current share count.
“Nvidia may be the top gun of AI, but investors should be careful not to write checks the stock can’t cash.”
Quite so.
AI is still a nascent technology and it is impossible to know, from here, who may be the greatest winners from it over time.
Just as investors back in 1999, trying to predict who would be the world’s biggest winners from widespread adoption of the internet, could not have known.
Donald Trump has said he plans to hit Canada with a 35% tariff on imported goods, as he warned of a blanket 15 or 20% hike for most other countries.
In a letter to Canadian Prime Minister Mark Carney, the US president wrote: “I must mention that the flow of Fentanyl is hardly the only challenge we have with Canada, which has many Tariff, and Non-Tariff, Policies and Trade Barriers.”
Mr Trump’s tariffs were allegedly an effort to get Canada to crack down on fentanyl smuggling, and the US president has expressed frustration with Canada’s trade deficit with the US.
In a statement Mr Carney said: “Throughout the current trade negotiations with the United States, the Canadian government has steadfastly defended our workers and businesses. We will continue to do so as we work towards the revised deadline of August 1.”
He added: “Canada has made vital progress to stop the scourge of fentanyl in North America. We are committed to continuing to work with the United States to save lives and protect communities in both our countries.”
The higher rates would go into effect on 1 August.
Shortly after Mr Trump unveiled his “Liberation Day” tariffs on 2 April, there was a huge sell-off on the financial markets. The US president later announced a 90-day negotiating period, during which a 10% baseline tariff would be charged on most imported goods.

“We’re just going to say all of the remaining countries are going to pay, whether it’s 20% or 15%. We’ll work that out now,” he said.
He added: “I think the tariffs have been very well-received. The stock market hit a new high today.”
The US and UK signed a trade deal in June, with the US president calling it “a fair deal for both” and saying it will “produce a lot of jobs, a lot of income”.
Sir Keir Starmer said the document “implements” the deal to cut tariffs on cars and aerospace, adding: “So this is a very good day for both of our countries – a real sign of strength.”
It comes as Russia’s deputy foreign minister, Sergei Ryabkov, said a new round of talks between Moscow and Washington on bilateral problems could take place before the end of the summer.
A Palestinian activist who was detained for over three months in a US immigration jail after protesting against Israel is suing Donald Trump’s administration for $20m (£15m) in damages.
Lawyers for Mahmoud Khalil have filed a claim against the administration alleging he was falsely imprisoned, maliciously prosecuted and smeared as an antisemite as the government sought to deport him over his role in campus protests.
He described “plain-clothed agents and unmarked cars” taking him “from one place to another, expecting you just to follow orders and shackled all the time”, which he said was “really scary”.

Mahmoud Khalil reunites with family after release
Mr Khalil said he was not presented with an arrest warrant and wasn’t told where he was being taken.
He said the detention centre he was taken to was “as far from humane as it could be” and “a place where you have no rights whatsoever”.
“You share a dorm with over 70 men with no privacy, with lights on all the time, with really terrible food. You’re basically being dehumanised at every opportunity. It’s a black hole,” he added.
Mr Khalil said he would also accept an official apology from the Trump administration.
The Trump administration celebrated Mr Khalil’s arrest, promising to deport him and others whose protests against Israel it declared were “pro-terrorist, antisemitic, anti-American activity”.
Mr Khalil said after around 36 hours in captivity he was allowed to speak to his wife, who was pregnant at the time.
“These were very scary hours, I did not know what was happening on the outside. I did not know that my wife was safe,” he said.
Mr Khalil said administration officials had made “absolutely absurd allegations” by saying he as involved in antisemitic activities and supporting Hamas.
“They are weaponising antisemitism, weaponising anti-terrorism in order to stifle speech,” he said. “What I was engaged in is simply opposing a genocide, opposing war crimes, opposing Columbia University’s complicity in the war on Gaza.”
A State Department spokesperson said its actions toward Mr Khalil were fully supported by the law.

Asked about missing the birth of his son while he was in prison, Mr Khalil said: “I don’t think there’s any word that can describe the agony and the sadness that I went through, to be deprived from such a divine moment, from a moment that my wife and I had always dreamed about.”
Meanwhile, the deportation case against Mr Khalil is continuing to wind its way through the immigration court system.
Donald Trump has praised the Liberian president’s command of English – the West African country’s official language.
The US president reacted with visible surprise to Joseph Boakai’s English-speaking skills during a White House meeting with leaders from the region on Wednesday.
After the Liberian president finished his brief remarks, Mr Trump told him he speaks “such good English” and asked: “Where did you learn to speak so beautifully?”
Mr Trump seemed surprised when Mr Boakai laughed and responded he learned in Liberia.
The US president said: “It’s beautiful English.
“I have people at this table who can’t speak nearly as well.”
Mr Boakai did not tell Mr Trump that English is the official language of Liberia.
The country was founded in 1822 with the aim of relocating freed African slaves and freeborn black citizens from the US.

Later asked by a reporter if he’ll visit the continent, Mr Trump said, “At some point, I would like to go to Africa.”
But he added that he’d “have to see what the schedule looks like”.
Trump’s predecessor, President Joe Biden, promised to go to Africa in 2023, but only fulfilled the commitment by visiting Angola in December 2024, just weeks before he left office.
