Dell, Super Micro, or HPE: Which AI Server Stock Crushed It in April?

The April scoreboard is in for the three biggest pure plays on artificial intelligence (AI) server hardware, and the spread between first and last is wider than the headline gains suggest. Shares of Dell Technologies (NYSE:DELL | DELL Price Prediction) closed the month up 28%, pulling away from Hewlett Packard Enterprise (NYSE:HPE) at 21% and Super Micro Computer (NASDAQ:SMCI) at 20%.

Dell, HPE, and SMCI all rode the same multi-trillion-dollar AI capital expenditure (CapEx) wave, yet each business model translated that tailwind into very different April returns. The reasons say a lot about where the smart money is concentrating right now.

The year-to-date (YTD) results sharpen the picture. Dell stock is up 67% in 2026, HPE is up 20%, and SMCI sits at -7% despite the April rebound.

Dell Takes April With Scale and No Legal Overhang

Dell stock rose from $163.64 on March 31 to $208.95 on April 30, its best month of the year. The Q4 FY2026 print from late February still sets the tone, with AI-optimized server revenue hitting $8.95 billion, up 342% year over year (YoY).

Management’s FY2027 outlook calls for AI server revenue near $50 billion, roughly doubling YoY, on top of a $43 billion backlog entering the new fiscal year. Dell paired the report with a 20% dividend hike and a $10 billion buyback authorization increase, both supporting per-share metrics.

Retail sentiment confirmed the institutional shift. r/stocks scored DELL at 68 (bullish) on April 25, a sharp reversal from the bearish 22 reading on April 1. With no legal overhang, hyperscaler request for proposal (RFP) wins on PowerEdge, and PowerStore storage benefiting from the same data buildout, Dell entered May atop the leaderboard.

HPE Earns Second on Juniper and Margin Inflection

HPE stock climbed from $23.81 to $28.77 in April, riding momentum from the March 9 earnings beat. Q1 FY2026 revenue of $9.3 billion grew 18% YoY, with the networking segment surging 152% to $2.71 billion on Juniper Networks integration.

CEO Antonio Neri called it “one of our most profitable quarters on record,” declaring the integration ahead of plan. HPE raised full-year non-GAAP earnings per share (EPS) guidance to $2.30 to $2.50, while free cash flow swung to $708 million from negative $877 million a year earlier.

The catch is HPE’s enterprise tilt. Enterprise customers ramp AI deployments more slowly than hyperscalers, and the Cray high-performance computing (HPC) franchise is well-positioned for sovereign AI, but those revenues are lumpy. Strong quarter, slower translation to monthly stock returns.

SMCI Lands Third Despite Pure-Play Status

Super Micro shares rose from $22.77 to $27.40, a solid gain that still trailed peers. CEO Charles Liang described the company as “scaling rapidly to support large AI and enterprise deployments,” and the direct liquid cooling (DLC) franchise remains tightly tied to graphics processing unit (GPU) buildouts.

A major issue may have capped the rally: the Department of Justice (DOJ) overhang and pending shareholder lawsuits continue to compress the multiple. Super Micro’s CEO commentary on AI buildout still puts the company at the heart of the cycle, but the legal overhang gates the re-rating.

SMCI stock also entered April recovering from a deeper hole, down 14% over one year. Reddit reflected the whiplash, with sentiment swinging from 12 (very bearish) on April 4 to 62 (bullish) by April 22, before going unclassified after the Oracle news.

What to Watch Into May

Keep an eye on hyperscaler CapEx commentary as the largest cloud players report May earnings, since those numbers feed directly into Dell, HPE, and SMCI order books. PowerEdge sell-through and any fresh Dell hyperscaler win could extend the leadership.

For HPE, the next Juniper integration update and Q2 FY2026 revenue guidance of $9.6 billion to $10 billion set the bar. For SMCI, watch for whether the legal overhang shows signs of resolution, since that’s the gating factor for multiple expansion. Through April, Dell wears the crown, and prudent investors may want to size positions accordingly while monitoring the May data.
