Jim Cramer's Hedge Fund Instinct Kicks In on 2 AI Stocks

Nvidia and CrowdStrike have surged roughly 1,400% and 875%, respectively since January 2023. Those kinds of gains can feel like confirmation that AI is the trade of the decade.

CNBC Mad Money host Jim Cramer, a former hedge fund manager who earned 24% annually over 14 years, recently weighed in on both names, and his verdict may help you check if you're financially ahead of the curve or chasing a rally that has already run.

Nvidia's Q2 delivered another blowout quarter

Nvidia Corp. (NASDAQ: NVDA) continued to print numbers that would have seemed implausible two years ago. The company reported Q2 fiscal 2027 revenue of $96.2 billion, up 106% year over year, with non-GAAP earnings of $2.22 per share, according to its earnings release.

That per-share figure represented a 120% jump from the same period a year earlier, driven largely by accelerating demand for its AI training and inference chips. Your portfolio's AI exposure likely traces back to this one chipmaker in some form.

Why Cramer says the valuation still works

Despite a market cap that dwarfs most economies, Cramer argued that Nvidia remains attractively priced relative to its growth. He pointed to a PEG ratio of 0.5, meaning the stock trades at roughly half the level its projected earnings growth would justify, according to the Motley Fool.

At 36 times earnings with projected annual growth of 72% through January 2028, that ratio stands out among mega-cap tech names. Wall Street's median price target of $318 implies about 42% upside from recent levels near $223.

The data center engine behind the numbers

Data center revenue hit $89 billion in the quarter, up 117% and accounting for roughly 93% of total sales, Nvidia's filing noted. That concentration is both the bull case and the risk. Nvidia's GPUs account for nearly 90% of AI accelerator sales, Cramer noted, giving it pricing power few competitors can match right now.

The company also leads in networking and CPU supply for data centers. For you as an investor, that dominance means the company's fortunes are tightly linked to how long hyperscalers keep spending on AI infrastructure.

Margins and shareholder returns held firm

Gross margins held at 75% during the quarter, and the company returned roughly $26 billion to shareholders through buybacks and dividends, according to Nvidia's filing. That level of capital return signals management's confidence in its cash generation.

If you are reinvesting dividends, that payout adds compounding on top of share price gains. Cramer described the combination of high margins, strong buybacks, and a sub-1 PEG ratio as a setup more typical of a value stock than a growth name near record highs, the Motley Fool added.

CrowdStrike's Q2 hit records across the board

CrowdStrike Holdings Inc. (NASDAQ: CRWD) posted its own strong quarter, clearing expectations on several fronts. Key highlights from the Q2 fiscal 2027 earnings release.

• Revenue of $1.47 billion, up 26% year over year
• Annual recurring revenue of $5.84 billion, up 25%
• Record net new ARR of $332.8 million, a 51% acceleration from the prior year
• Record Q2 free cash flow of $377.4 million

Subscription revenue accounted for $1.40 billion of the total, growing 27%, which confirmed the platform's hold on recurring enterprise contracts.

Cramer's split signal on CrowdStrike

Cramer acknowledged CrowdStrike's strength but warned that the stock's valuation, at roughly 230 times earnings, makes it hard to recommend buying today, according to the Motley Fool. With shares already up 115% year to date, much of the good news appears priced in.

The median analyst target of $245 sits slightly below the recent price near $255, suggesting limited near-term upside. His advice was to keep the name on a watchlist and wait for a pullback that resets the risk-reward balance.

Why CrowdStrike's AI security thesis matters long-term

CrowdStrike's Falcon platform spans 34 cybersecurity modules covering endpoint security, identity protection, cloud workloads, and threat intelligence, the Motley Fool explained. As companies adopt more AI tools, the attack surface grows, and the company appears positioned to capture that demand.

Management raised its full-year net new ARR growth outlook by 630 basis points to 34% at the midpoint, a sign that deal pipelines remain healthy. Cramer indicated the business earns its premium over time, even if the stock price has gotten ahead of itself for now.

What could go wrong with both names

Nvidia's Q3 fiscal 2027 guidance of $108 billion in revenue implies growth is already decelerating from the triple-digit pace, and any signal that hyperscaler spending is plateauing could weigh on the stock.

CrowdStrike faces projected earnings growth of 28% annually through January 2028, solid but perhaps not enough to justify the current multiple if competition from Palo Alto Networks or Microsoft tightens. For your portfolio, sizing positions to match your risk tolerance matters more than picking a side in the AI race.

Bottom line

Cramer's hedge fund background shapes how he reads these two stocks. Nvidia's PEG ratio of 0.5 signals a rare gap between price and growth, while CrowdStrike's 230 times earnings multiple calls for patience even after a record quarter.

If you are weighing where to start investing in AI, the contrast between these two names shows why valuation discipline can matter as much as picking the right business. Both are growing, but only one is priced to reward new buyers today.
