Nvidia (NVDA 6.18%) was the talk of the town in 2023, and it continues to be a Wall Street darling in 2024. It's arguably the single most important stock behind the artificial intelligence trend currently fueling the market.

As Nvidia has climbed higher and the broad market also reaches new all-time highs, skeptics have sounded the alarm for a stock market bubble. And while the market is stretched thinner than in years past, there's still reason to believe Nvidia is not necessarily overvalued, despite its 439% gain since the beginning of 2023.

Red hot growth

Say what you want about Nvidia stock's epic rise, but the company is delivering on every measure with a one-two punch of high revenue growth and expanding margins.

Revenue has more than tripled in the last year, while net income is up over 500%. That level of growth for a company as big as Nvidia is incredible.

An understandable valuation

The past year of gains has also pushed Nvidia to trade with a 66.2 price-to-earnings (P/E) ratio, a steep premium to even its "Magnificent Seven" peers. However, the average analyst estimate for Nvidia's fiscal 2025 earnings per share is $23.92, roughly double last year's result.

The surge in anticipated profits gives Nvidia a much more reasonable forward P/E ratio. In fact, Nvidia has a lower forward-looking valuation than Tesla, Amazon, and Microsoft.

You would be hard-pressed to find a growth stock that has nearly quadrupled in the last year with that low of a forward P/E ratio.

The pitfalls of cyclical stocks

At the same time, there are a few reasons why focusing only on forward P/E is dangerous for a company like Nvidia. First, Nvidia still has to double its profits in the current fiscal year -- a high bar for any company, let alone one this size. The even more significant risk to consider is that Nvidia operates in a cyclical industry.

Typically, cyclical stocks have low P/E ratios during an expansion and high P/E ratios during a downturn. The idea is that investors won't pay too high of a price during times of elevated earnings but also won't sell off a stock just because there's a contraction in the cycle. Over time, the median P/E ratio works itself out to something more reasonable.

A good example is agriculture and construction giant Deere. The company's earnings are slowing as the current expansion period nears an end. However, Deere's P/E ratio is just 10.6 because its trailing earnings are high, but investor sentiment is negative (shares are down 14% in the past year). Its 10-year median P/E ratio is a much higher 17.1 -- which makes sense -- the long-term median should be higher than Deere's current valuation. But in a downturn, investors can expect Deere's P/E to climb higher than that long-term baseline.

The opposite is happening with Nvidia. Its 66.1 P/E is higher than its 46.7 10-year median. But again, you could argue Nvidia deserves a much higher valuation given its scorching hot growth rate and earnings outlook for this year.

The story is getting better, but it's still a story

Nvidia is exciting because it's growing quickly, and it's already such a valuable company that it can drive the whole market. Nvidia has already become a bit of a story stock, a company valued based more on its hype and potential than its fundamentals. But Nvidia isn't priced for perfection, either -- its 32.1 forward P/E ratio is reasonable, especially relative to the other "Magnificent Seven" stocks. After all, Nvidia has almost always carried a premium, and there's no reason that should change in this part of its growth journey.

Personally, I'd prefer to buy Nvidia when the expectations are lower, and there's more margin for error. Nvidia's short-term performance could take a turn for the worse due to macroeconomic conditions and factors outside its control. And with the stock sitting at its peak, there's a heavy expectation its growth will march on uninterrupted. A forward P/E ratio above 30 is acceptable for a company likely to double its earnings this year, but that will change quickly if the company fails to deliver.

Prospective investors should be cautious about those expectations, as well as the behavior patterns of cyclical stocks. The easy money has already been made, and with Nvidia's market cap reaching $2 trillion, expecting the stock to again triple in the near term isn't realistic.

As an individual investor considering Nvidia for your portfolio, it's up to you to decide what kind of price you're willing to pay for the stock and what you expect from the business at that price.
