<p><strong>Nvidia</strong> <span class="ticker-mention inline-flex items-center font-bold">(NVDA <span class="ml-1 text-red-900">3.30%</span>)</span> stock has cooled off recently. After hitting a 52-week high of $212.19 in late October, shares closed out last week at $175.02 -- a decline of about 17%. This comes as sentiment around AI (artificial intelligence) has become less forgiving as investors demand clearer returns on the spending and look for evidence that the current AI boom can keep chugging along for the foreseeable future.</p><p>Nvidia, which sells the market-leading graphics processing units (GPUs) that power the data centers used to train and run AI models, has been a major beneficiary of the AI boom. But this also means that the stock could suffer if demand for AI computing slows.</p><p>However, despite sentiment toward AI turning more negative recently, demand for AI chips remains extremely robust. So, is the stock's recent sell-off a buying opportunity?</p><div><img alt="An AI chip." width="880" height="495" src="https://imageproxy.pbkrs.com/https://g.foolcdn.com/image//query-b3A9cmVzaXplJnVybD1odHRwczovL2cuZm9vbGNkbi5jb20vZWRpdG9yaWFsL2ltYWdlcy84NDcyMTkvaXMtbnZkYS1zdG9jay1hLWJ1eS1ub3cuanBnJnc9Mzg0MA?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" original-src="https://imageproxy.pbkrs.com/https://g.foolcdn.com/image//query-b3A9cmVzaXplJnVybD1odHRwczovL2cuZm9vbGNkbi5jb20vZWRpdG9yaWFsL2ltYWdlcy84NDcyMTkvaXMtbnZkYS1zdG9jay1hLWJ1eS1ub3cuanBnJnc9Mzg0MA"/><p>Image source: Getty Images.</p></div><h2>Demand is still rising</h2><p>A glance at Nvidia's fiscal third-quarter results certainly doesn't indicate that the AI boom is cooling off.</p><div><div id="foolcom_sidebar_top_container"></div></div><p>&#34;Blackwell sales are off the charts, and cloud GPUs are sold out,&#34; Nvidia CEO Jensen Huang said in the company's fiscal third-quarter earnings release. </p><div><div><div>Advertisement</div><div><div></div></div></div></div><p>The tech company's fiscal third-quarter revenue rose 62% year over year to $57.0 billion. That was faster than the 56% year-over-year increase Nvidia reported in fiscal Q2. This marked a return to accelerating growth after fiscal Q2's top-line growth rate decelerated.</p><div><div id="in_line_article_pitch_container"></div></div><p>The data center segment, where most AI hardware demand sits, told a similarly bullish story in fiscal Q3. The segment's revenue grew 66% year over year in the third quarter to $51.2 billion -- up from 56% growth in the prior quarter.</p><p>Further, Nvidia's profitability continued to impress.

At the midpoint, that implies about 14% sequential growth and roughly 65% year-over-year growth.</p><div></div><h2>A great business, but a risky stock</h2><p>For investors looking to get in on this growth story, the pullback in the stock price certainly helps. But the setback may not be significant enough to fully price in some of the stock's biggest risks.</p><p>Shares currently trade at about 43 times earnings. A valuation multiple like this makes sense if Nvidia can sustain its rapid growth and maintain its high gross margin in the 70s. But if investors start to see signs that either of these important factors behind Nvidia's valuation is at risk, the stock could take an even bigger hit.</p><p>The risk is not that Nvidia suddenly stumbles in execution. This is unlikely. The bigger risk is that the AI buildout takes a breather. After all, the semiconductor industry has been cyclical for years -- and it's unlikely that this will ever change.</p><p>Competition is also intensifying. Some customers, including deep-pocketed tech giants <strong>Alphabet</strong> and <strong>Amazon</strong>, are designing their own chips. If they come up with reasonable alternatives to Nvidia's GPUs, investors could get spooked.</p><div></div><p>And export rules remain another wild card. Nvidia has shown it can grow rapidly while even when China's demand fades in importance. But because of regulatory and geopolitical concerns about sales of AI chips to China, there's ultimately less visibility about Nvidia's potential in the important market than there is in the U.S.</p><section><div><div><div><small><div>Expand</div></small></div><div><img alt="Nvidia Stock Quote" width="64" height="64" src="https://imageproxy.pbkrs.com/https://g.foolcdn.com/image//query-b3A9cmVzaXplJnVybD1odHRwczovL2cuZm9vbGNkbi5jb20vYXJ0L2NvbXBhbnlsb2dvcy9tYXJrL05WREEucG5nJnc9MTI4?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" original-src="https://imageproxy.pbkrs.com/https://g.foolcdn.com/image//query-b3A9cmVzaXplJnVybD1odHRwczovL2cuZm9vbGNkbi5jb20vYXJ0L2NvbXBhbnlsb2dvcy9tYXJrL05WREEucG5nJnc9MTI4"/></div><div><h2>NASDAQ: NVDA</h2><div>Nvidia</div></div></div><div><div><div>Today's Change</div><div>(-3.30%) $-5.97</div><div>Current Price</div><div>$174.96</div></div><div></div></div></div><div><div></div><div><h3>Key Data Points</h3><div><div>Market Cap</div><div>$4.3T</div><div>Day's Range</div><div>$174.62 - $182.81</div><div>52wk Range</div><div>$86.62 - $212.19</div><div>Volume</div><div>6.2M</div><div>Avg Vol</div><div>191M</div><div>Gross Margin</div><div>70.05%</div><div>Dividend Yield</div><div>0.02%</div></div></div></div></section><p>Sure, the stock's pullback makes Nvidia shares more interesting than they were a few months ago.

<p>Nvidia's stock has dropped 17% from its 52-week high due to investor concerns about the sustainability of the AI boom. Despite robust demand for AI chips and strong fiscal Q3 results, including a 62% revenue increase, the stock's high valuation poses risks. Competition and geopolitical factors add uncertainty. While the pullback makes the stock more attractive, the lack of a sufficient margin of safety suggests caution for potential investors.</p>

- Nvidia's stock has declined about 17% from its 52-week high, reflecting investor concerns over the sustainability of the AI boom.  
- Despite this, Nvidia's fiscal third-quarter results show strong demand for AI chips, with revenue rising 62% year over year and guidance for continued growth.  
- However, the stock's high valuation poses risks, as any signs of a slowdown in AI demand could lead to significant price drops, necessitating caution for potential investors.
