Nvidia’s earnings surpass expectations.

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

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, soaring 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%.

Rich Sparkle Holdings’ recent surge was mainly due to asset restructuring. According to 21st Century Business Herald, publicly available 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 viral influencer Khaby Lame (“Silent Brother”) holding 49% of shares, 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 earnings exceed expectations

Globally, Nvidia has once again delivered impressive financial results. As of January 25, for the fourth quarter of fiscal year 2026, the company’s key indicators all exceeded Wall Street expectations: revenue of $68.1 billion, up 73% year-over-year, surpassing 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 beating 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 closed up over 9%, Shudi Shares hit the daily limit. Additionally, Gaolan Shares hit the daily limit during trading, while Mingyang Circuit and Runze Technology also rose over 10%.

Unveiling high-growth concept stocks

Tianfeng Securities stated that before the holiday, the tech sector was not entirely weakening; the excess drag was mainly from overseas SaaS reflecting AI applications. The release of strong earnings reports and optimistic guidance have stabilized overseas SaaS stock prices, and the panic phase is nearing its end. Currently, the overall TMT sector is overweight by 17 percentage points, but marginal changes in overweight ratios are not highly significant for next quarter’s guidance. Moreover, the sector-specific overweight coefficients have not reached extreme convergence thresholds, and institutional holdings are not at their limits. Looking ahead, sectors with “rapid order improvement” or “order support” can be identified through indicators like “accounts receivable + contract liabilities.” In terms of industry cycle signals, storage cycles still show 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 profitability in stages. Taking Nvidia in the U.S. stock market as an example, this logical switch is clearly observable. Correspondingly, in 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 stage driven by earnings.

Within the AI industry chain, Nvidia concept stocks show relatively stronger performance realization. According to Data Treasure, among Nvidia concept stocks rated by more than three institutions, 17 stocks are forecasted to have net profit growth rates exceeding 30% for both this year and the next. Notably, stocks like Shenghong Technology, Helin Micro Nano, Dingtong Technology, and Magmet are expected to see net profit growth exceeding 50% over the next two years.
