Super Micro’s stock sinks 33% after co-founder’s indictment. Here are Wall Street’s biggest questions.

While Super Micro wasn’t named in a recently unsealed lawsuit, analysts say the charges raise concerns about credibility and controls

Super Micro Computer’s stock saw one of its biggest single-day drops in history on Friday, as Wall Street assessed the fallout of a co-founder’s indictment for alleged export-control violations.

While the server maker itself wasn’t named in a newly unsealed indictment, federal prosecutors have charged Wally Liaw, a Super Micro 

 co-founder and vice president of business development, with participation in a scheme that unlawfully diverted advanced Nvidia  chips to China.

Liaw resigned from Super Micro in 2018 after an accounting scandal, but was rehired as a full-time employee in 2022 and named to the company’s board of directors the next year.

The company announced after Friday’s closing bell that Liaw had resigned from the board. A day earlier, Super Micro said he had been put on administrative leave.

“It’s one thing being duped once by rogue employees (allegedly) committing crime right under your nose, but [it’s] quite another hiring the same person back (as a board director too) and later for that same person to (allegedly) do something worse like this,” Bernstein analyst Mark Newman wrote in a note to clients.

The indictment “raises serious credibility issues that could impact business,” he added.

Raymond James analyst Simon Leopold agreed that “the incident will reflect poorly on a company with a tarnished history.”

Super Micro shares fell 33% on Friday, in what was its second-steepest daily drop on record.

The company immediately tried to distance itself from the two employees and one contractor indicted by the U.S. government. “The conduct by these individuals alleged in the indictment is a contravention of the company’s policies and compliance controls, including efforts to circumvent applicable export control laws and regulations,” Super Micro said in a press release on Thursday.

The company “maintains a robust compliance program and is committed to full adherence to all applicable U.S. export and re-export control laws and regulations,” it added at the time.

Super Micro didn’t respond to a MarketWatch request for comment. MarketWatch was not immediately able to contact Liaw or other individuals named in the indictment.

Here are some of Wall Street’s biggest questions in the aftermath of the charges.

How deep does the problem go?

Liaw, along with fellow Super Micro employee Ruei-Tsang Chang and contractor Ting-Wei Sun, was accused of working with a company in Southeast Asia to order “large allocations” of the U.S. company’s servers, then supporting the “onward transshipment to China.”

The indictment alleges that the three arranged for servers valued at $2.5 billion to be illegally diverted. Prosecutors charge that the scheme involved using hair dryers to transfer serial numbers from real Super Micro servers to “dummy” versions to conceal from inspectors that the actual Super Micro servers were in China.

“The key question is whether this is an isolated case of ‘rogue employees’ or evidence of systemic compliance gaps inside [Super Micro’s] global sales and channel operations,” Bernstein’s Newman wrote.

The indictment “introduces a new legal/compliance overhang” for the company, Raymond James’s Leopold wrote. And Liaw’s status as a board member invites a more expansive list of reputation-related questions, he added.

The magnitude of the charges “may affect customer trust and supply chain relationships,” Leopold said, particularly with Nvidia and other U.S. hyperscalers and customers that are bound to comply with export controls.

Super Micro announced after Friday’s close that it had named DeAnna Luna its acting chief compliance officer. She is the company’s vice president of global trade and sanctions compliance.

Will Super Micro lose out on sales?

Newman wondered whether Nvidia will “feel the need to further distance” itself from Super Micro in the wake of the scandal.

If so, Super Micro could lose out on its supply of Nvidia graphics processing units, “which in turn could have devastating impact” on the server maker, Newman wrote.

Wedbush’s Matt Bryson also saw “room for concern as to how this
development might affect [Super Micro’s] business, including its relationships with suppliers and customers.”

Does Dell stand to gain?

Dell Technologies shares 

 were up more than 8% at session highs, but gave back most of their gains by the close. Still, analysts suggested the server company could capitalize on its rival’s struggles.

“Dell might be the most immediate beneficiary as Dell has emerged as the other significant supplier of AI servers/equipment to large non-hyperscale AI customers,” Bryson wrote.

He also flagged Cisco Systems 

 and Hewlett Packard Enterprise 

 as companies that could benefit if Super Micro sees its operations severely disrupted.

Did Nvidia know anything?

Nvidia’s stock fell more than 3% on Friday, though Bernstein’s Newman doesn’t think the company appears to have “any fault” in the alleged scheme involving Super Micro employees, he said.

“Nowhere” in the indictment “does it suggest that Nvidia had any knowledge or inkling as to what may have (allegedly) been going on, and we are confident that the company takes their responsibilities around the current export control regime extremely seriously,” Newman noted.

In a statement, an Nvidia spokesperson said: “Unlawful diversion of controlled U.S. computers to China is a losing proposition across the board.” The company “does not provide any service or support for such systems, and the enforcement mechanisms are rigorous and effective,” the spokesperson added.

美超微高层与承包商合谋将AI技术转移中国遭起诉

 路透社华盛顿消息,美国司法部周四19日表示,与人工智能优化伺服器制造商美超微公司(Super Micro Computer Inc)有关的一名台裔高层与两名台人,包括其共同创办人,被指控合谋非法将美国人工智能技术转移至中国。


据路透社引述美国联邦调查局表示,廖益贤(Yih-Shyan Liaw)、张瑞沧(音译,Ruei-Tsang Chang)和孙廷伟(音译,Ting-Wei Sun)“涉嫌合谋向中国买家出售价值数十亿美元的伺服器,这些伺服器集成了受管制的敏感图形处理单元(GPU),违反了美国出口管制法律。” 许多高性能人工智能伺服器使用英伟达的芯片,其中部分受到出口限制。

总部位于加利福尼亚州圣何塞的美超微表示,公司已于周四收到联邦检方关于该起诉的通知,但公司本身并未被列为被告。

美超微还说,已让廖益贤和张瑞沧停职,并终止了与作为承包商的孙廷伟的合作关系。

按美超微官网资料,廖益贤于1993年共同创立了美超微,原是董事会的一员,自2022年起担任负责业务发展的资深副总裁。

美国司法部指控这三人参与了一项系统性计划,将大量人工智能技术转移给中国客户。

司法部声明未直接点名美超微,但表示廖益贤是“一家总部位于美国、设计并制造高性能人工智能与云计算伺服器(包括集成人工智能GPU伺服器)的上市公司的共同创办人、董事会成员及业务发展高级副总裁。”

据悉,张瑞沧是超微台湾办公室的销售总经理,孙廷伟则为承包商。

这份起诉书于周四在曼哈顿联邦法院解封。美国司法部表示,美国公民廖益贤和台湾公民孙廷伟已于周四被捕,而台湾公民张瑞沧目前在逃。

美国司法部称:“被告及其同伙合谋,在未获得美国商务部许可的情况下,系统性地将该美国制造商搭载特定GPU的伺服器转移至中国。”

美司法部还指,被告涉嫌伪造文件、通过摆放虚假设备以通过库存审计,并利用“中间公司”掩盖不当行为及真实客户名单。

另综合台媒报道表示,这些服务器在美国组装完成后先运往美超微位于台湾的设施,再从台湾出货至东南亚。

美国司法部说,从监视器画面可见,东南亚公司的员工用吹风机将服务器上的卷标移除,并把卷标贴上充当检查替身的假服务器上,而真正的服务器则在没有标签的包装下送到中国客户手上。

与此同时,美超微则表示,公司正配合政府调查。

公司表示:“起诉书中指控的这些个人行为违反了公司的政策与合规控制,包括试图规避适用的出口管制法律和法规。”

据美联社最新消息,廖益贤周四已交保获释,而孙廷伟的保释庭将于周五召开。

本文更新截稿前,美超微 (SMCI-US) 周五盘前股价下跌 26.08%,每股暂报 22.76 美元,市值报 184.89 亿美元。

受 AI 需求带动,美超微市值曾在 2024 年攀升至约 670 亿美元高点,但随着高成本伺服器压缩利润,加上过去遭放空机构兴登堡 (Hindenburg) 质疑,公司股价近来承压。此次司法风波进一步加剧市场对其营运前景的疑虑。

Which stock trading systems, such as ORB strategy?

 

Which stock trading systems, such as ORB strategy?

Besides the ORB (Opening Range Breakout) strategy, stock trading systems are mainly categorized into trend-following, reversal, momentum, and quantitative strategies. Classic strategies include the Turtle Trading System, MACD/EMA moving average system, Bollinger Band breakout, SAR stop-loss reversal system, and breakout strategies based on volume (OBV) or volatility (ATR).
Main stock trading strategy systems:
  1. Trend Following System:
    • Turtle Trading System:  A classic rule-based trend-following system that buys and sells based on Donchian Channel breakouts.
    • Moving average crossover system:  For example, buy when the fast line (such as 10-day) crosses above the slow line (such as 30-day) and sell when it crosses below.
    • MACD/EMA Trading System:  Use the MACD histogram or EMA trend line to determine bull and bear market trends.
  2. Volatility/Breakout System:
    • ORB Strategy:  Focus on the breakout of the highest/lowest price in the 15-60 minutes before the market opens to capture the trend throughout the day.
    • Volatility Breakout:  Calculates buy and sell ranges using ATR (Average True Range) to adapt to markets with different volatility levels.
    • Box/Channel Breakout:  Buy when the price breaks through the upper edge of the previous consolidation box.
  3. Classic Quantitative and Technical Indicator Systems:
    • OBV (On Balance Volume) trading system:  volume-balanced trading confirms the authenticity of price trends.
    • Parabolic SAR (Stop and Reverse SAR):  Used for trend following and setting trailing stop-loss levels.
    • Triple Screen:  Combining different timeframes (such as weekly trends, daily pullbacks, and hourly entry points) to improve win rate.
  4. Short-term/intraday strategy:
    • Scalping:  High-frequency profiting from small fluctuations in liquidity over a period of seconds to minutes.
    • Mean Reversion:  This theory suggests that price fluctuations will revert to their mean after deviating from it. It is commonly seen in RSI overbought and oversold trading scenarios.
These systems are typically used in conjunction with professional apps such as Eastmoney and Huatai XX (Zhangle Wealth Pass) for quantitative evaluation and execution.

how to short adbe stock today at 6:46 AM PST using options

 To short Adobe (ADBE) stock using options before the market opens at 6:46 AM PST (9:46 AM ET), you must use pre-market trading, although most options trading occurs during regular hours (9:30 AM–4:00 PM ET). The primary strategies include buying Put Options (long put) for a directional bearish bet or implementing a Bear Call Spread (sell call, buy higher call) to profit from a price drop or stagnation.

Steps to Short ADBE Options Pre-Market
  1. Access Pre-Market: Log into a brokerage that supports pre-market option trading (e.g., thinkorswim, Tastytrade) between 4:00 AM and 8:00 PM ET.
  2. Select Strategy:
    • Long Put: Buy a Put option with a strike price below the current ADBE price, betting on a further decline.
    • Bear Call Spread: Sell a call and buy a higher-strike call to limit risk while betting on a downward trend, as noted in this YouTube video.
  3. Execute Order: Use a Limit Order rather than a Market Order to avoid poor pricing caused by low liquidity in the pre-market.
  4. Identify Strike/Date: Select a near-term expiration (e.g., Friday of this week) to maximize sensitivity to immediate price drops, according to Barchart.com.
Key Considerations
  • Liquidity: Options liquidity is lower at 6:46 AM PST, often leading to wider bid-ask spreads.
  • Risk: Shorting via options can lead to losing the entire premium paid for puts, while uncovered call selling can have unlimited risk.
  • Market Context: ADBE has experienced high volatility recently due to earnings and structural changes, which impacts option premiums as shown in this YouTube video.
Disclaimer: Options trading involves high risk and is not suitable for all investors. Ensure you understand the risks before trading.

哪些股票交易系统, 比如ORB strategy

除了ORB(开盘区间突破)策略,股票交易系统主要分为趋势跟踪、反转、动量和量化策略等类别。经典策略包括海龟交易系统、MACD/EMA均线系统、布林带突破、SAR停损转向系统以及基于成交量(OBV)或波动率(ATR)的突破策略。
主要股票交易策略系统:
  1. 趋势跟踪系统 (Trend Following):
    • 海龟交易系统 (Turtle Trading): 经典的规则化趋势跟踪系统,基于唐奇安通道(Donchian Channels)突破进行买卖。
    • 均线交叉系统 (MA Crossover): 例如快线(如10日)上穿慢线(如30日)买入,下穿卖出。
    • MACD/EMA交易系统: 利用MACD柱状图或EMA趋势线确定牛熊走势。
  2. 波动性/突破系统 (Volatility/Breakout):
    • ORB 策略: 聚焦开盘前15-60分钟最高/最低价的突破,捕捉全天趋势。
    • 波动性突破 (Volatility Breakout): 利用ATR(真实波动幅度均值)计算买卖区间,适应不同波动率市场。
    • 箱体/通道突破: 价格突破前期整理箱体上沿买入。
  3. 经典量化与技术指标系统:
    • OBV 交易系统 (On Balance Volume): 成交量平衡交易,确认价格趋势的真实性。
    • SAR 停损转向 (Parabolic SAR): 用于趋势追踪和设定移动止损位。
    • 三重滤网 (Triple Screen): 结合不同时间周期(如周线趋势、日线回调、小时线入场)提高胜率。
  4. 短线/日内策略:
    • 剥头皮 (Scalping): 在几秒到几分钟内利用流动性小幅波动高频获利。
    • 均值回归 (Mean Reversion): 认为价格波动偏离均值后会回归,常见于RSI超买超卖操作。
这些系统通常通过如东方财富、华泰XX(涨乐财富通)等专业APP结合进行量化测评和执行。
