"Crazy Little Yang Brother" Concept Stock Surges 64x Then Plummets 96%! Nvidia Concept Stocks with Sustained High Growth Emerge (List Attached)

NVIDIA’s earnings exceed expectations.

“Crazy Little Yang Brother” concept stocks, soaring and plummeting

Recently, a U.S. listed company has attracted widespread market attention, with its stock price experiencing dramatic rises and falls.

Rich Sparkle Holdings went public on NASDAQ in July 2025, with an offering price of $4. Since then, the stock has seen astonishing volatility, rising above $50 in August 2025, then falling below $20 by the end of November 2025.

In January 2026, it started another surge, reaching over $180 on January 15, with a maximum increase of nearly 64 times. However, the stock’s rapid rise and fall intensified, dropping to around $8 within just over 20 trading days, with a maximum decline of nearly 96%.

The recent surge of Rich Sparkle Holdings is mainly due to asset restructuring. According to 21st Century Business Herald, public information shows that in January 2026, Rich Sparkle announced the completion of its acquisition of Step Distinctive. The target company operates e-commerce live streaming sales, with TikTok viral influencer Khaby Lame (“Silent Brother”) holding 49%, and Anhui Little Black Sheep Network Technology Co., Ltd. holding 13%.

This Anhui Little Black Sheep Network Technology Co., Ltd., in the full equity penetration chart, is wholly owned by Hefei Leading Culture Media Co., Ltd., which is held by Zhang Qingyang (“Crazy Little Yang Brother”) and Zhang Kaiyang (“Crazy Big Yang Brother”) with 51% and 49%, respectively. They are the founders of Three Sheep.

NVIDIA’s performance exceeds expectations

Globally, NVIDIA has once again delivered impressive financial results. As of the fourth quarter of fiscal year 2026 ending January 25, the company’s key indicators all surpassed Wall Street expectations: revenue of $68.1 billion, up 73% year-over-year, exceeding the expected $65.9 billion; adjusted earnings per share of $1.62, higher than the consensus of $1.53; adjusted gross margin of 75.2%, still rising despite a high base. Meanwhile, NVIDIA provided a revenue guidance of $78 billion for the current quarter, significantly surpassing market expectations.

Following this positive news, on the morning of February 26, related A-share sectors surged sharply, including circuit boards, optoelectronic switches, optical communications, and liquid-cooled servers. Some heavyweight stocks soared: Shenghong Technology (300476) closed up over 9%, and Shulian Co., Ltd. (002463) hit the daily limit. Additionally, Gaolan Co., Ltd. (300499) hit the limit during intraday trading, and Mingyang Circuit (300739), Runze Technology (300442), and others rose over 10%.

Unveiling high-growth concept stocks

Tianfeng Securities (601162) stated that before the holiday, the tech sector was not entirely weakening; the excess drag came from overseas SaaS reflecting AI applications. The release of earnings reports and optimistic guidance have stabilized overseas SaaS stock prices, and the panic phase is nearing its end. Currently, TMT (Technology, Media, Telecom) is over-allocated by 17 percentage points, but marginal changes in allocation have little significance for next quarter’s excess guidance. The sector’s segmented track record shows that the over-allocation coefficient has not reached extreme convergence, and institutional holdings are not at their limit. Looking ahead, sectors with “rapid order improvement” or “orders supported” can be identified through indicators like “accounts receivable + contract liabilities.” In terms of industry cycle signals, the storage industry still maintains high prosperity.

HuaFu Securities bluntly stated that the China-U.S. AI industry may rise again. In the industry transformation driven by technological revolutions, the core driving force often shifts from valuation to profit phase. Taking U.S. stocks like NVIDIA as an example, this logical switch can be clearly observed. For the A-share AI industry chain, represented by the Artificial Intelligence Index, the current market is still mainly valuation-driven. If companies within the industry chain can gradually realize performance, this sector may enter a second phase driven by actual results.

Within the AI industry chain, NVIDIA concept stocks show relatively stronger performance realization. According to data from Data Treasure, among more than three institutional ratings of NVIDIA concept stocks, 17 stocks are unanimously predicted by institutions to have net profit growth rates exceeding 30% in the next two years. Among them, Shenghong Technology, Helin Micro Nano, Dingtong Technology, and Magmet (002851) are expected to have net profit growth rates over 50% in the next two years.
