Palantir Technologies (PLTR 3.34%) has amazed investors quarter after quarter with its earnings growth -- this is thanks to a more than 20-year-old, well-established software business and the company's integration of artificial intelligence (AI) into its platforms. Customers from governments to commercial players have flocked to Palantir for software that's helped them become more efficient and has supercharged their operations.
Palantir's stock performance has reflected this success, as the shares have soared more than 2,400% over the past three years. This is fantastic news for those who got in early on this company's story, but in recent times, even as Palantir continues to report explosive growth, some analysts have expressed concern about one big problem that this company and its investors face. In fact, most Wall Street analysts who cover the stock don't recommend buying it right now -- the most common recommendation currently is a "hold."
Let's find out why Wall Street is warning investors about this AI player that's seen its shares skyrocket.

Palantir's success story
First, though, it's important to take a look at how and why Palantir has become so successful. As mentioned, the company isn't new to the software business, and over time developed high-quality platforms that help its customers analyze and make better use of their data -- which often are quite scattered. This unorganized data is no problem for Palantir. The company has been able to bring this valuable information together for its customers so they may use it to launch game-changing decisions or plans.
In Palantir's early days, it relied on the U.S. government for most of its business, but in recent quarters -- especially after the launch of its Artificial Intelligence Platform (AIP) two years ago -- the commercial customer has emerged as a key growth driver. Companies from United Airlines to mining leader Rio Tinto Group have turned to Palantir and are seeing results. For example, Rio Tinto says AIP has helped it access its unstructured data and take on problems that before seemed too complicated.
Commercial revenue skyrockets
Palantir's latest earnings report, delivered this week, confirmed the ongoing strength of the company's platforms. In the quarter, the tech player recorded double-digit gains in U.S. government revenue, and a triple-digit increase in U.S. commercial revenue. Total revenue advanced 63% to more than $1.1 billion, and importantly, Palantir once again demonstrated that it's balancing this tremendous growth with profitability.
We can see this in its Rule of 40 score, which reached a mind-boggling 114%. To put this into perspective, consider that, generally, a score of 40% is considered good, showing a software player has managed growth and profitability.
On top of this, Palantir raised annual forecasts for revenue, U.S. commercial revenue, adjusted income from operations, and adjusted free cash flow.
In spite of this show-stopping performance, Palantir stock declined after the news. And this brings me back to the problem Palantir faces right now -- the one that has prompted Wall Street to warn investors about buying the stock.

Key Data Points
Palantir's big problem
This problem is valuation. Though Palantir is seeing tremendous growth, some say the stock performance well accounts for that and for growth in the coming months. This is because Palantir stock right now trades for more than 300x forward earnings estimates. By comparison, AI chip giant Nvidia, a company with much higher earnings levels, trades for about 45x forward earnings estimates today.

So, analysts worry that, at this valuation, Palantir stock may be ripe for a decline -- in fact, the average forecast calls for a 16% decrease over the coming 12 months.
Now the big question is: What should investors do? After all, Palantir's earnings are rock solid, demand for its software continues at a healthy pace, and signs such as customer count and deal size suggest we may be in the early days of commercial customer growth.
It's important to remember that valuation includes earnings estimates for the year to come -- but doesn't consider the company's potential a few years down the road. At that point, the valuation picture could change. Still, today's valuation may scare off some investors and put the brakes on Palantir's stock performance in the near term.
All of this means the decision about whether to buy Palantir depends on your investment style. If you're a cautious or value investor, Palantir clearly isn't the right choice for you. But if you're an aggressive investor who owns a diversified portfolio and who aims to hold onto investments for the long term, any dip in Palantir stock could represent a great buying opportunity.
