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 announced a 10% trade tariff on all imports from the UK – as he unleashed sweeping tariffs across the globe.
Speaking at a White House event entitled “Make America Wealthy Again”, the president held up a chart detailing the worst offenders – which also showed the new tariffs the US would be imposing.
“This is Liberation Day,” he told a cheering audience of supporters, while hitting out at foreign “cheaters”.
He claimed “trillions” of dollars from the “reciprocal” levies he was imposing on others’ trade barriers would provide relief for the US taxpayer and restore US jobs and factories.
Mr Trump said the US has been “looted, pillaged, raped, plundered” by other nations.

His first tariff announcement was a 25% duty on all car imports from midnight – 5am on Thursday, UK time.
Mr Trump confirmed the European Union would face a 20% reciprocal tariff on all other imports. China’s rate was set at 34%.
The UK’s rate of 10% was perhaps a shot across the bows over the country’s 20% VAT rate, though the president’s board suggested a 10% tariff imbalance between the two nations.
It was also confirmed that further US tariffs were planned on some individual sectors including semiconductors, pharmaceuticals and critical mineral imports.

Trump’s tariffs explained
The ramping up of duties promises to be painful for the global economy. Tariffs on steel and aluminium are already in effect.
The UK government signalled there would be no immediate retaliation.
Business and Trade Secretary Jonathan Reynolds said: “We will always act in the best interests of UK businesses and consumers. That’s why, throughout the last few weeks, the government has been fully focused on negotiating an economic deal with the United States that strengthens our existing fair and balanced trading relationship.
“The US is our closest ally, so our approach is to remain calm and committed to doing this deal, which we hope will mitigate the impact of what has been announced today.
“We have a range of tools at our disposal and we will not hesitate to act. We will continue to engage with UK businesses including on their assessment of the impact of any further steps we take.
“Nobody wants a trade war and our intention remains to secure a deal. But nothing is off the table and the government will do everything necessary to defend the UK’s national interest.”

Who showed up for Trump’s tariff address?
The EU has pledged to retaliate, which is a problem for Northern Ireland.
Should that scenario play out, the region faces the prospect of rising prices because all its imports are tied to EU rules under post-Brexit trading arrangements.
It means US goods shipped to Northern Ireland would be subject to the EU’s reprisals.
The impact of a trade war would be expected to be widely negative, with tit-for-tat tariffs risking job losses, a ramping up of prices and cooling of global trade.
Research for the Institute for Public Policy Research has suggested more than 25,000 direct jobs in the UK car manufacturing industry alone could be at risk from the tariffs on car exports to the US.
The Society of Motor Manufacturers and Traders (SMMT) had said the tariff costs could not be absorbed by manufacturers and may lead to a review of output.
The tariffs now on UK exports pose a big risk to growth and the so-called headroom Chancellor Rachel Reeves was forced to restore to the public finances at the spring statement, risking further spending cuts or tax rises ahead to meet her fiscal rules.
A member of the Office for Budget Responsibility (OBR), David Miles, told MPs on Tuesday that US tariffs at 20% or 25% maintained on the UK for five years would “knock out all the headroom the government currently has”.
But he added that a “very limited tariff war” that the UK stays out of could be “mildly positive”.
He said: “There’s a bit of trade that will get diverted to the UK, and some of the exports from China, for example, that would have gone to the US, they’ll be looking for a home for them in the rest of the world.
“And stuff would be available in the UK a bit cheaper than otherwise would have been. So there is one, not central scenario at all, which is very, very mildly potentially positive to the UK. All the other ones which involve the UK facing tariffs are negative, and they’re negative to very different extents.”
Actors, directors and celebrity friends have paid tribute to Val Kilmer, after he died aged 65.
The California-born star of Top Gun, Batman and Heat died of pneumonia on Tuesday night in Los Angeles, his daughter Mercedes told the Associated Press.
She said Kilmer was diagnosed with throat cancer in 2014 but later recovered.
Tributes flooded in after reports broke of the actor’s death, with No Country For Old Men star Josh Brolin among the first to share their memories.

World leaders have begun reacting after Donald Trump announced sweeping tariffs across the world.
Mr Tump announced a 10% trade tariff on all imports from the UK.
He said he would impose a 10% baseline tariff on all imports to the US and higher duties on some of the country’s biggest trading partners.
Speaking at a White House event entitled ‘Make America Wealthy Again’, the president held up a chart detailing the worst offenders, hitting at foreign “cheaters”.
These are some of the world leaders’ reactions.

Trump’s tariffs explained
Irish Prime Minister Micheal Martin has said there is “no justification” for US tariffs.
“I deeply regret the US decision to impose 20% tariffs on imports from across the European Union,” the taoiseach added.
“We see no justification for this. More than €4.2bn worth of goods and services are traded between the EU and the US daily.
“Disrupting this deeply integrated relationship benefits no one. Tariffs drive inflation, hurt people on both sides of the Atlantic, and put jobs at risk.”

Manfred Weber, the president of the largest party in the European Parliament, the EPP, said: “To our American friends, today isn’t liberation day – it’s resentment day. Donald Trump’s tariffs don’t defend fair trade; they attack it out of fear and hurt both sides of the Atlantic.
“Europe stands united, ready to defend its interests, and open to fair, firm talks.”
What to expect from the EU
There will be a response from the European Union – the question is how soon, and how tough.
A symbolic reprisal is one choice – putting tariffs on classic American products such as Harley-Davidson motorbikes or bottles of bourbon.
That won’t damage the European economy, but it won’t make much of a difference, either.
There’s a reluctance to slap wide-ranging, indiscriminate tariffs simply because that would increase costs for many European manufacturers.
So something more targeted may look appealing and that could mean going after the tech giants – Facebook, Apple, Google, Amazon, for example.
Companies who have already had rows with EU regulators and are seen as being, to varying extents, close to the White House.
If Europe could specifically target Tesla, it probably would.
There are also those suggesting the EU should hold fire for the moment, confident that Trump’s tariffs will backfire and keen that the effects are visible.
One fear is that some of the cheap goods that were destined for US markets will now be diverted to Europe, flooding its market.
Another fear is how the Windsor Framework will be affected, now that there are different US tariffs on either side of the Irish border.
And finally there is that insult from the President, who called the European Union “pathetic”. A few minutes later, a senior EU diplomat sent me a message saying “the US is Brexiting the world, but you can’t stop the march of folly”.
Transatlantic relations are getting even icier.
Canadian Prime Minister Mark Carney said his country would fight tariffs with countermeasures.
“It’s essential to act with purpose and with force, and that’s what we will do,” he told reporters ahead of a cabinet meeting to discuss Canada’s response.
Australian Prime Minister Anthony Albanese said: “It is the American people who will pay the biggest price for these unjustified tariffs.
“This is why our government will not be seeking to impose reciprocal tariffs. We will not join a race to the bottom that leads to higher prices and slower growth.”
Italian Prime Minister Giorgia Meloni, seen as close ally of the US president, called the tariffs “wrong” and said they would not benefit the United States.
“We will do everything we can to work towards an agreement with the United States, with the goal of avoiding a trade war that would inevitably weaken the West in favour of other global players,” she said.
The Spanish Prime Minister Pedro Sanchez vowed to protect the country’s companies and workers and to “continue to be committed to an open world.”
His Swedish counterpart, Ulf Kristersson, said: “We don’t want growing trade barriers.
“We don’t want a trade war.
“We want to find our way back to a path of trade and cooperation together with the US, so that people in our countries can enjoy a better life.”
