Continuously high-growth NVIDIA concept stocks released (with list) NVIDIA's performance exceeded expectations. The "Crazy Little Yang Brother" concept stock has seen wild fluctuations. Recently, a U.S. listed company has attracted widespread attention in the market, with its stock price experiencing dramatic rises and falls. Rich Sparkle Holdings went public on NASDAQ in July 2025 at an issue price of $4. Since then, the stock has experienced astonishing volatility, climbing above $50 in August 2025 and then dropping below $20 by the end of November 2025. In January 2026, the stock surged again, reaching over $180 on January 15, with a maximum increase of nearly 64 times. However, the volatility was even more extreme, as the stock plummeted to around $8 within just over 20 trading days, with a maximum decline of nearly 96%. The recent surge in Rich Sparkle Holdings is primarily due to asset restructuring. According to the 21st Century Business Herald, public information shows that in January 2026, the U.S. listed company Rich Sparkle announced the completion of its acquisition of Step Distinctive. The target company operates an e-commerce live streaming business, with TikTok phenomenon influencer Khaby Lame holding 49% and Anhui Little Black Sheep Network Technology Co., Ltd. holding 13%. This Anhui Little Black Sheep Network Technology Co., Ltd. is fully owned by Hefei Leading Sheep Cultural Media Co., Ltd., which is held 51% by Zhang Qingyang ("Crazy Little Yang Brother") and 49% by Zhang Kaiyang ("Crazy Big Yang Brother"), who are the founders of San Zhi Yang. NVIDIA's performance exceeded expectations. With global attention, NVIDIA has once again delivered impressive financial results. For the fourth quarter of fiscal year 2026 ending January 25, the company's core metrics significantly surpassed Wall Street expectations: revenue reached $68.1 billion, a 73% year-on-year increase, exceeding the expected $65.9 billion; adjusted earnings per share were $1.62, higher than the consensus of $1.53; and the adjusted gross margin was 75.2%, still rising despite a high base. Additionally, NVIDIA's revenue guidance for the current quarter is as high as $78 billion, greatly exceeding market expectations. Under the influence of this positive news, on the morning of February 26, related sectors in the A-share market saw significant increases, with concepts such as circuit boards, optical circuit switches, optical communications, and liquid-cooled servers all surging. Some heavyweight stocks rose sharply, with Shenghong Technology closing up over 9% in the morning, and Hu Dian Co., Ltd. hitting the daily limit. Furthermore, Gao Lan Co., Ltd. saw a "20cm" limit up during the day, while Mingyang Circuit and Runze Technology also rose over 10% Revealing the Concept Stocks of Sustained High Growth Tianfeng Securities (Rights Protection) stated that the technology sector is not experiencing a comprehensive downturn before the holiday; the excessive drag comes from AI applications mapped by overseas SaaS. The release of financial reports and optimistic performance guidance have stabilized the stock prices of overseas SaaS, and the panic sentiment phase may be nearing its end. Currently, the overall TMT sector is overweight by 17 percentage points, but the marginal change in the overweight ratio has little significance for the excess guidance in the next quarter, and the overweight coefficient of segmented tracks has not reached the extreme threshold of excess convergence, with institutional holding density not reaching its limit. Looking ahead, one can look for segmented industries with "rapid improvement in order status" or "orders supported" along the "deferred revenue + contract liabilities" indicators. In terms of industrial prosperity clues, the large cycle of storage still shows high prosperity. Huafu Securities bluntly stated that the AI industry in China and the United States may rise again. In the industrial transformation triggered by the technological revolution, the core driving force of the market often presents a phased characteristic of transitioning from valuation to profitability. Taking NVIDIA in the U.S. stock market as an example, one can clearly observe this driving logic switch. Corresponding to the A-share AI industry chain, represented by the artificial intelligence index, the current market may still be in a phase primarily driven by valuation. If companies within the industry chain can gradually realize performance, this sector may gradually enter the second phase of performance-driven market. In the AI industry chain, the performance realization of NVIDIA concept stocks is relatively stronger. According to data from Data Treasure, among NVIDIA concept stocks rated by more than three institutions, 17 stocks are expected by institutions to have a net profit growth rate exceeding 30% in the next two years. Among them, Shenghong Technology, Helin Micro-Nano, Dingtong Technology, and Magic Microelectronics are expected to have a net profit growth rate exceeding 50% in the next two years. ### 相關股票 - [Rich Sparkle (ANPA.US)](https://longbridge.com/zh-HK/quote/ANPA.US.md) - [Direxion Daily NVDA Bull 2X Shares (NVDU.US)](https://longbridge.com/zh-HK/quote/NVDU.US.md) - [YieldMax NVDA Option Income Strategy ETF (NVDY.US)](https://longbridge.com/zh-HK/quote/NVDY.US.md) - [AXS 1.5X NVDA Bear Daily ETF (NVDS.US)](https://longbridge.com/zh-HK/quote/NVDS.US.md) - [T-Rex 2X Inverse NVIDIA Daily Target ETF (NVDQ.US)](https://longbridge.com/zh-HK/quote/NVDQ.US.md) - [Direxion Daily NVDA Bear 1X ETF (NVDD.US)](https://longbridge.com/zh-HK/quote/NVDD.US.md) - [GraniteShares 2x Short NVDA Daily ETF (NVD.US)](https://longbridge.com/zh-HK/quote/NVD.US.md) - [T-Rex 2X Long NVIDIA Daily Target ETF (NVDX.US)](https://longbridge.com/zh-HK/quote/NVDX.US.md) - [GraniteShares 2x Long NVDA Daily ETF (NVDL.US)](https://longbridge.com/zh-HK/quote/NVDL.US.md) - [NVIDIA (NVDA.US)](https://longbridge.com/zh-HK/quote/NVDA.US.md) ## 相關資訊與研究 - [LPU: Nvidia popularizes a new AI acronym](https://longbridge.com/zh-HK/news/279662346.md) - [Planet to build world’s first GPU-native AI engine for planetary intelligence with Nvidia](https://longbridge.com/zh-HK/news/279330399.md) - [Bones Studio to Release BONES-SEED - the First Multimodal Motion Dataset Purpose-Built for Humanoid Robotics | NVDA Stock News](https://longbridge.com/zh-HK/news/279340216.md) - [Nvidia Asked by US Senators to Provide Details on Groq Deal](https://longbridge.com/zh-HK/news/279931631.md) - [Nvidia's $20B Groq Deal Draws US Antitrust Questions](https://longbridge.com/zh-HK/news/279978880.md)
