3 Reasons Why Nvidia Stock Is Still Undervalued and Worth Buying in March

Nvidia (NASDAQ: NVDA) has produced jaw-dropping returns in recent years, with the stock price up 1,110% since the start of 2023. With that kind of gain, calling Nvidia undervalued seems ludicrous.

Here are three reasons Nvidia stock is still a bargain for investors considering it now despite trading near its all-time high set in late October 2025.

1. Nvidia continues to generate high-margin growth

On Feb. 25, Nvidia reported $215.9 billion in fiscal 2026 revenue. For context, Nvidia booked $27 billion in fiscal 2023 revenue -- representing an eightfold jump in three years.

The massive increase illustrates how artificial intelligence (AI) has fundamentally changed Nvidia. Data center growth deserves virtually all the credit, as Nvidia earned $193.7 billion in data center revenue in fiscal 2026, up from $15 billion in fiscal 2023.

Despite being a much larger company, Nvidia's margins are actually higher now than they were a few years ago -- a testament to its pricing power and customer willingness to pay a premium price for performance.

In fiscal 2026, Nvidia achieved 71% gross margins, 60.6% operating margins, and 55.6% net profit margins -- allowing it to rake in a staggering $120.1 billion in net income.

2. Nvidia is relentless about innovation

One of the main arguments against buying Nvidia has been the risk that its margins will decline due to weaker pricing power, lower demand, and competition. But Nvidia continues to prove the doubters wrong, not because it is overcharging for its products and squeezing customers, but because it is delivering massive improvements that justify premium pricing.

In its latest earnings release, Nvidia cited research stating that Blackwell Ultra, which is an upgrade to the initial Blackwell architecture, delivers up to 50 times better performance and 35 times lower costs for agentic AI compared to the Nvidia Hopper platform, which predated Blackwell.

Nvidia's next platform, called Rubin, uses six different chips that achieve even greater performance improvements and cost reductions through what Nvidia calls "extreme codesign." This is basically integrating software and hardware for rack-scale data center applications -- such as designing Nvidia's graphics processing units alongside NVLink switches rather than as separate offerings.

Agentic AI follows generative AI as the next step on Nvidia's AI roadmap. With Nvidia forecasting exponential future growth in physical AI (autonomous vehicles and general robotics), the company should be able to retain its high margins for years to come.

3. Nvidia is raising its stock repurchases

Nvidia's high margins allow it to generate substantial excess cash flow beyond what it needs for its long-term investments, which means Nvidia can freely buy back boatloads of its own stock without impacting its balance sheet or taking dry powder away from innovation.

In fiscal 2026, Nvidia bought back $40.1 billion in stock compared to $33.7 billion in fiscal 2025 and $9.5 billion in fiscal 2024.

Given Nvidia's $4.3 trillion market cap, it's hard for buybacks to make a dent in its share count. But they will add up over time by reducing Nvidia's share count and accelerating earnings-per-share growth.

At 39.9 times fiscal 2026 earnings, Nvidia may not look undervalued. But when factoring in its high margin earnings, runway for future earnings growth, and ability to buy back increasing amounts of stock, Nvidia is arguably a much better value than the S&P 500, which trades at 29.9 times earnings.
