Below the headlines, a quieter move was underway. The seven best-performing stocks in the Russell 2000 each more than doubled Micron’s return in a single month. ## The May Small-Cap Leaderboard The table below ranks the seven Russell 2000 names by month-to-date performance. Company Month-To-Date Return **Hyliion Holdings Corp**. (NYSE:HYLN) +213.6% **agilon health, inc.** (NYSE:AGL) +209.1% **Rackspace Technology, Inc.** (NASDAQ:RXT) +184.3% **Entravision Communications Corp.** (NYSE:EVC) +161.0% **NextNRG, Inc**. (NASDAQ:NXXT) +132.5% **Innodata Inc.** (NASDAQ:INOD) +126.1% **Ambiq Micro, Inc.** (NYSE:AMBQ) +117.9% _Data as of May 25, 2026_ **Read Also: Forget About Micron: The Hottest US Semiconductor Stock Is Already Up 100% This Month** ## What Actually Drove Each Move? Each of the seven rallies had a specific trigger, and most of them landed in the first two weeks of May. Here is the catalyst behind each name. - **Hyliion Holdings Corp.**: Two catalysts, two legs. Hyliion reported on May 12 with revenue up 479% year over year and a narrower net loss, and the stock jumped roughly 30% on the print as the company confirmed it had cleared UL certification testing for its KARNO Power Module. The second leg came late in the month: the U.S. Navy selected the KARNO platform for power trials on the unmanned USX-1 Defiant vessel, and the stock surged another 40% in the days that followed, trading near $6. An earnings pop, then a defense headline on top. - **agilon health, inc.**: The senior-care company reported stronger first-quarter profitability and raised its full-year 2026 sales guidance, a combination that reversed a long stretch of weak sentiment. The stock gapped up 117.8% the next session, opening near $44 and closing above $60. It did not stop there. Shares climbed for most of the rest of the month, reaching the mid-$80s. Deutsche Bank upgraded the stock to Buy from Hold during the month. - **Rackspace Technology, Inc**: Rackspace reported on May 6, and the stock posted back-to-back daily gains near 55% in each of the two sessions that followed, lifted by a swing to first-quarter profit and a multi-year AI infrastructure partnership with **Advanced Micro Devices, Inc**. (NASDAQ:AMD) announced on May 7. With roughly 21% of its float sold short heading into the news, the move was amplified by short covering. Shares ran from roughly $2.50 to above $7.50 in days. The retracement was just as sharp: by late May the stock had fallen back near $4.  - **Entravision Communications Corporation**:The media and ad-tech company reported first-quarter results on May 5 showing revenue up 114% year over year to about $197 million and a return to profitability. The gain was driven by its Advertising Technology and Services segment, where revenue rose 204%. Management also pointed to the 2026 political advertising cycle as a coming tailwind. Shares rallied 94% in the post-earnings session and continued to drift higher thereafter. - **NextNRG, Inc.**:The AI-driven energy and mobile-fueling company reported that April 2026 was the highest single revenue month in its history, with monthly revenue of roughly $21 million. The move is best read as a sharp rebound: the stock remains down about 41% year to date, and its financing leans on convertible notes that can dilute shareholders. - **Innodata Inc.**:The data-engineering supplier reported first-quarter results on May 7 with revenue up 54% year over year and lifted its full-year 2026 growth target above 40%. The stock gapped 86% higher on the print and extended through the month. Wedbush raised its price target to $100 from $80 the following week, the clearest analyst endorsement in the group. - **Ambiq Micro, Inc.**: The ultra-low-power chipmaker reported first-quarter net sales up 59% year over year on May 12, with more than 80% of units shipped running AI algorithms on the device. Management guided second-quarter sales higher still. **Read Also: A New Chipmaker Just Topped Micron's 2026 Return, Thanks To Nvidia** ### Related Stocks - [AGL.US](https://longbridge.com/en/quote/AGL.US.md) - [RXT.US](https://longbridge.com/en/quote/RXT.US.md) - [HYLN.US](https://longbridge.com/en/quote/HYLN.US.md) - [IWN.US](https://longbridge.com/en/quote/IWN.US.md) - [IWO.US](https://longbridge.com/en/quote/IWO.US.md) - [TNA.US](https://longbridge.com/en/quote/TNA.US.md) - [VBK.US](https://longbridge.com/en/quote/VBK.US.md) - [IWM.US](https://longbridge.com/en/quote/IWM.US.md) - [MU.US](https://longbridge.com/en/quote/MU.US.md) - [EVC.US](https://longbridge.com/en/quote/EVC.US.md) - [NXXT.US](https://longbridge.com/en/quote/NXXT.US.md) - [INOD.US](https://longbridge.com/en/quote/INOD.US.md) - [AMBQ.US](https://longbridge.com/en/quote/AMBQ.US.md) - [AMD.US](https://longbridge.com/en/quote/AMD.US.md) - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) ## Related News & Research - [HYLN: Record Navy contract and higher revenue guidance drive focus on military and data center deployments](https://longbridge.com/en/news/295577530.md) - [RXT: Q2 2026 revenue grew 0.6% to $670M; net loss widened to $68M; FY 2026 revenue guided at $2.45–$2.55B](https://longbridge.com/en/news/295454040.md) - [RXT: Q2 2026 saw modest revenue growth, a wider net loss, and major investments in Enterprise AI](https://longbridge.com/en/news/295449638.md) - [Rackspace Q2 revenue beats analyst estimates on private cloud growth](https://longbridge.com/en/news/295445130.md) - [Hold Rating Maintained on agilon health as Turnaround Progress and Improved Guidance Appear Priced In](https://longbridge.com/en/news/295021794.md)
