Nvidia is the most valuable company on the planet. It is also, by one common yardstick, trading as cheaply as it has in years — a paradox now drawing sharp attention from investors.

According to Yahoo Finance, Nvidia's valuation has slipped to its lowest level since before 2019, even as Wall Street analysts continue to see strong upside for the stock. The gap reflects a simple tension: the company's profits have grown so fast that its share price, however high, now looks modest relative to earnings.

The contrast is stark enough to make headlines. The Irish Times, citing a Bloomberg headline, notes that Nvidia — the company at the center of the AI revolution — now trades more cheaply on a valuation basis than chocolate maker Hershey. On that measure, the world's priciest company looks like a bargain next to a candy business.

Momentum has cooled, too. The Motley Fool points out that Nvidia "crushed the market" in 2023, 2024, and 2025, but is losing to the broader market in 2026. That reversal has prompted the question analysts keep posing: is it time to walk away or double down?

The bullish case leans on that low valuation and on expectations, noted by outlets including MSN, that Nvidia could have a strong second half of the year. The bearish case is the plain fact that a former market leader is now lagging, testing investors' faith in the AI trade.

Why it matters: Nvidia sits at the heart of the AI boom, so how investors judge its "cheap" stock is really a referendum on whether the entire AI rally still has room to run.
