FINANCIAL and AI experts have applauded NVIDIA for its stellar Q3 results but warned investors against being overexposed to the stock, saying “smart money buys the ecosystem, not just the poster child”. One wealth manager cautioned: “Don’t risk more than you’re comfortable losing.”
Last night, in a week where investors have been worried about a potential US recession, NVIDIA reported record revenue for the third quarter ended October 26, 2025, of $57 billion, up 22% from the previous quarter and up 62% from a year ago.
In a further boost to investors, the company said revenue, for the fourth quarter, is expected to be $65 billion, plus or minus 2%.
“Blackwell sales are off the charts, and cloud GPUs are sold out,” said Jensen Huang, founder and CEO of NVIDIA. “Compute demand keeps accelerating and compounding across training and inference — each growing exponentially. We’ve entered the virtuous cycle of AI. The AI ecosystem is scaling fast — with more new foundation model makers, more AI startups, across more industries, and in more countries. AI is going everywhere, doing everything, all at once.”
During the first nine months of fiscal 2026, NVIDIA returned $37.0 billion to shareholders in the form of shares repurchased and cash dividends. As of the end of the third quarter, the company had $62.2 billion remaining under its share repurchase authorization.
Colette Mason, AI Consultant at London-based Clever Clogs AI, has no doubt AI is the future but warned investors to be wary of being overexposed to a single stock: “Can you afford to sit this out? No. AI is the industrial revolution of our lifetime, and missing it is a financial misstep.
“However, betting your house solely on NVIDIA is reckless. NVIDIA currently bears the weight of the world and, while it is delivering, the entire sector is sensitive to short-term shocks.
“Smart money buys the ecosystem, not just the poster child; look for ETFs like the L&G Artificial Intelligence UCITS ETF (Ticker: AIAG) or VanEck Semiconductor UCITS ETF (Ticker: SMGB) to spread risk.
“A sensible portfolio keeps this high-octane “satellite” exposure to around 5%-10%. NVIDIA is printing money, but when the whole market leans on one pillar, the foundations get shaky.”
David Belle, Trader at Fink Money, also said it’s hard for investors to now ignore AI: “People keep saying AI is a bubble, but when you have the world’s leading AI firm beating earnings consistently, you have to wonder whether the detractors are looking at a different set of data — or in a different dimension altogether.
“People who refuse to hold AI in their portfolio are the same people who questioned the invention of the wheel.”
Tony Redondo, Founder at Newquay-based Cosmos Currency Exchange, said the NVIDIA results have heralded a brave new world and that “the virtuous cycle is real”.
But he warned: “Single-stock risk is brutal at 50x forward P/E. You can get AI exposure via ETFs without betting the farm.
“For the risk-averse, perhaps allocate up to 10%, for those with risk appetite, an aggressive 30% of the portfolio.
“Yes, markets are dangerously hooked on the Magnificent 7 that currently account for 37% of the S&P500, so cap AI at a third of equities and hedge with value/international. Own the trend, not the headline stock.”
Samuel Mather-Holgate, Independent Financial Adviser at Swindon-based Mather and Murray Financial, said NVIDIA “seems to be unstoppable, the demand for its chips insatiable, and it continues to smash market expectations”.
But he warned: “Even against these results, the valuation is high and significant further earnings growth would be needed to justify current price levels. Smaller ‘picks and shovels’ investments might be a wiser play in AI, like the Korean market as a whole to diversify portfolios.”
Rob Mansfield, Independent Financial Advisor at Tonbridge-based Rootes Wealth Management, also urged investors to be cautious and shared his tips for getting exposure: “NVIDIA is performing fantastically well at the moment but with a share price up over 1,300% in the past five years, how much future growth and expectations are already baked into the price?
“As an investor you could either follow the market with a tracker fund or take a more active approach. A tracker could be a broad-based market one or a more sector-specific one and so you’ve got lots of options as an investor. Some active managers will be holding lots of NVIDIA and others will be avoiding it.
“Personally, I’m wary that AI has a lot of hype and that the practical use cases are currently overstated but visionaries will say that the pace of development is so rapid, it’ll catch up. You only ever truly know after the event. Don’t risk more than you’re comfortable losing.”
Riz Malik, Director at Southend-on-Sea-based R3 Wealth, said: “The AI train has undoubtedly contributed to the growth in many portfolios over the past few years. However, fund managers will be watching the sector closely even after NVIDIA’s strong earnings call.
“The Magnificent 7 have a disproportionate impact on the markets and have performed well in many portfolios but how long that will last is another question.”
