Apple shares reached a fresh all-time high on September 21, 2026. The stock touched nearly $345 intraday before settling near $339.
NVIDIA, meanwhile, trades near record levels, even as its forward valuation multiple has compressed sharply from earlier this year.
What’s Really Driving Apple’s Record-Breaking Rally
A forward price-to-earnings ratio measures a stock’s current price against analysts’ projected future earnings. It offers a snapshot of how expensive a company looks relative to expected growth. That distinction matters for understanding what’s happening between these two tech giants right now.
Apple’s rally reflects renewed confidence in its hardware and services ecosystem. Strong demand for the latest iPhone models, particularly the iPhone 18 Pro and the upcoming foldable iPhone Duo, has extended delivery times and lifted upgrade-cycle expectations.
Improvements to on-device Siri AI and a smooth CEO transition have further reassured investors that Apple can monetize artificial intelligence without the massive capital spending required by hyperscalers.
The stock has climbed more than 36% over the trailing 12 months, according to TradingView data, pushing its market cap above $5 trillion.
Services revenue and high-margin software continue expanding Apple’s cash-generation machine, giving investors a steadier growth story than many of its AI-exposed peers currently offer.

Why Has NVIDIA’s Valuation Compressed So Much?
NVIDIA’s fundamentals remain exceptional on paper. Recent quarterly revenue exceeded $96 billion, up more than 100% year over year, with data-center sales driving the bulk of that growth.
Yet NVIDIA’s forward price-to-earnings ratio has fallen sharply from levels above 25x earlier this year, even as shares trade near record territory.
Investors appear to be pricing in risks around potential slowdowns in AI capital expenditure, competition from custom chips, memory-cost pressures, and the sheer scale of expectations already embedded in current forecasts.
This de-rating has occurred even as NVIDIA shares remain well above prior-year levels and are still up meaningfully in 2026. The stock simply hasn’t kept pace with the explosive rise in its own earnings power, creating a valuation gap rarely seen for the company in recent years.
The divergence highlights two very different investor mindsets at work. Apple is being rewarded for steady, high-quality growth and capital discipline. NVIDIA is being scrutinized for whether its extraordinary growth rate can hold, even though that growth remains genuinely robust today.
Whether NVIDIA’s more modest multiple represents a buying opportunity or an early warning will likely depend on upcoming hyperscaler earnings and capital-spending guidance in the months ahead.
