NVIDIA Stock and the Gravity of Great Margins

The company’s extraordinary profitability has powered its historic run, but that very success creates a powerful incentive for the market to pull it back to earth.

After a run that has seen NVIDIA (NVDA) stock climb 55.1% in the last year, it’s easy to focus on the revenue growth. But for an investor holding the stock today, the more telling number—the one that holds the most risk—isn’t about the top line. It’s about what’s left over.

The figure worth your attention is the company’s net profit margin. It’s the simple percentage of revenue that NVIDIA keeps as pure profit, and right now, that figure is at a level that should give any long-term holder pause.

A Peak That’s Hard to Sustain

Over the last twelve months, NVIDIA has posted a net margin of 63.0%. To understand how notable that is, you have to compare it to the company’s own history. That 63.0% figure is the highest it has been in at least five years and stands far above its own 3-year average of 51.5%. Beyond being a good number, it’s an outlier, even for a company accustomed to success.

Profitability this high is fundamentally difficult to maintain. It acts as a strong beacon for competition, signaling that there are significant profits to be had for anyone who can challenge the incumbent. It also gives the company’s largest and most powerful customers—the hyperscale cloud providers who buy chips by the truckload—a strong incentive to push back, either by negotiating prices down or by investing in their own custom silicon to claw some of that margin back for themselves.

How Good Margins Go Bad

The mechanism here is simple economic gravity. When a company enjoys such a profitable position, the market works to correct it. Competitors will try to undercut on price to gain a foothold. Customers, aware of the high margins, will use their purchasing power to demand better terms. This isn’t a sign of failure; it’s the normal functioning of a competitive market.

For NVIDIA, this means its current pricing power could face pressure. If competition or customer negotiations force prices down, or if the company has to spend more to fend them off, that 63.0% margin would be the first to decline. And because the profit base is so large, even a small percentage change has a significant impact.

What’s Riding on Profitability

With annual revenue of $253.5 billion, every percentage point of net margin is worth billions in pure profit. A reversion to the company’s 3-year average margin would represent a significant hit to the bottom line that everyone watches.

The stock’s valuation appears to be banking on these margins holding firm. While its price-to-earnings multiple of 26.5 is not at the high end of its historical range, the price-to-sales ratio of 16.7 suggests the market expects a large amount of profit to be generated from that revenue. If margins compress, the earnings that justify the stock price shrink, which could lead to a re-evaluation of what investors are willing to pay.

For now, the profits are rolling in. But the higher a margin gets, the more it has to lose. The single thing to watch is whether the company can continue to defy gravity.

Don’t Bet It All On One Number

That is the risk of owning any single stock: your outcome rests on one company getting it right. You do not have to concentrate risk that way. Rather than depend on NVIDIA alone, the Trefis High Quality (HQ) Portfolio spreads exposure across 30 high-quality stocks and rebalances them with discipline so that no single name carries an outsized share of your returns, and it has a track record of outpacing the S&P 500, S&P Mid-cap, and Russell 2000. If the risk we just walked through gives you pause, a diversified alternative like this is worth a serious look today.
