Aptiv PLC is an American[3][4] automotive technology supplier
Aptiv PLC is an American[3][4] automotive technology supplier with headquarters in Schaffhausen, Switzerland.[1] Aptiv grew out of the now-defunct American company, Delphi Automotive Systems, which itself was formerly a component of General Motors.[5]
History
The company was established as General Motors' Automotive Components Group in 1994, which changed its name to Delphi Automotive Systems in 1995.[6] G.M. also renamed the various divisions within the newly created Delphi unit. Packard Electric became Delphi Packard Electric Systems; Delco Chassis became Delphi Chassis Systems; Inland Fisher-Guide became Delphi Interior and Lighting Systems; Saginaw became Delphi Saginaw Steering Systems; Harrison Radiator became Delphi Harrison Thermal Systems, and AC Delco became Delphi Energy and Engine Management Systems.[6]
Why ServiceNow Stock Topped the Market Today
Why ServiceNow Stock Topped the Market Today
Not for the first time in recent weeks, the company has taken ownership of a cybersecurity specialist.
By Eric Volkman – Apr 21, 2026 at 6:07PM EST
Key Points
- These buys will enhance its native platform.
- Cybersecurity solutions are justifiably popular in a world loaded with hacking threats.
Enterprise software developer ServiceNow (NOW+0.42%) enjoyed a modest rally on the stock exchange Tuesday, with its shares gaining 0.4% on a day when the benchmark S&P 500 index landed in negative territory. Investors were cheered by the company's closing of its latest asset buy.
New month, new acquisition
Just after market close on Monday, ServiceNow divulged that it had completed its acquisition of cybersecurity company Armis. The deal was originally announced last December, with the two companies agreeing that ServiceNow would be Armis' new owner for roughly $7.75 billion in cash.
In its press release trumpeting the acquisition's close, ServiceNow said that owning Armis "extends ServiceNow's security platform into the physical and operational layers of the enterprise, adding the cyber asset intelligence foundation and business context that enterprises need to deploy agentic artificial intelligence (AI) with trust and control at scale."
ServiceNow has been on something of a cybersecurity shopping spree lately. Early last month it finalized the acquisition of identity security company Veza. In contrast to the Armis deal it did not disclose the price it paid, although reports from several media outlets put the cost at over $1 billion.
Spending while flush
ServiceNow wrote that it is funding the Armis deal with a combination of cash on hand and debt. It didn't provide more details. As of the end of 2025, it had a fairly solid position in cash and short-term investments of nearly $6.3 billion. Its long-term debt at that point stood at under $2.3 billion.
So while neither of these recent acquisitions is coming cheap, they're within ServiceNow's means to pay for them. And cybersecurity, in many forms, will always be mission-critical and important to a wide range of businesses worldwide. Both purchases look like clever, forward-thinking moves to me.

Order blocks with signals indicator | BSX stock | 2 hour Order block - Long area

BSX stock research | Order blocks with signals tradingview indicator
Top TradingView order block indicators with signals automatically identify institutional supply/demand zones, highlighting potential reversals or breakout areas, often with alert functionality for entry. Key options include vuetratrading's Order Blocks with signals, TehThomas's Order Blocks, and Algo Alpha's MA Order Blocks, which feature automatic mitigation, FVG filtering, and volume insights.
- Order Blocks with Signals (vuetratrading): A popular open-source script that automatically draws Blue (supply) and Green (demand) blocks, offering buy/sell alerts and options to mitigate blocks based on wicks or closes.
- Order Blocks (TehThomas): Uses 5-bar fractal patterns and Fair Value Gap (FVG) filtering to identify high-probability institutional zones, with automatic removal of tested (mitigated) blocks to keep charts clean.
- MA Order Blocks (Algo Alpha): Integrates a Hull Moving Average to determine the trend before identifying order blocks, providing a more structured, trend-following approach to order block trading.
- Order Blocks Zones with Signals (Uncle_the_shooter): Combines order blocks with Fair Value Gaps (FVG), highlighting areas where price moved strongly, indicating institutional activity.
- Order Blocks (flux chart): Highlights the last candle before strong moves (order blocks) and provides volume data (bullish/bearish ratio) to assess the strength of the zone.
- Breaker Blocks with Signals (LuxAlgo): Identifies "breaker blocks" (previously broken order blocks) which can act as support/resistance, providing signals for reversals when price breaks through a previously established order block.
- Automatic Mitigation: The indicator removes or fades the block once the price has passed through it, indicating it is no longer fresh.
- Volume Analysis: Some indicators provide the total volume and bullish/bearish volume ratio within the order block to gauge its strength.
- MTF (Multi-Timeframe): Allows viewing higher timeframe order blocks (e.g., 4-hour or Daily) on a lower timeframe chart.
- Alerts: Provides notifications when price re-enters a defined order block zone.
- Look for "Fresh" Blocks: The first time price returns to an order block (unmitigated), it is more likely to cause a significant reaction.
- Combine with Market Structure: Use order blocks in conjunction with market structure changes, such as a Break of Structure (BOS).
- Confirm with Volume: A strong move away from the order block with high volume confirms the zone's significance.
- Use Higher Timeframes: H1 or H4 charts often provide more reliable order blocks than lower timeframes, filtering out noise.
科技业寒冬?这家大厂惊传全球裁员3万 员工崩溃
全球软件巨头甲骨文(Oracle)惊传裁员消息。(示意图/pexels)
全球软件巨头甲骨文(Oracle)惊传大裁员,今(1)日不少员工一觉醒来发现自己公司系统登不进去,据悉甲骨文为了筹措建设人工智能数据中心的巨额资金,正在进行史上规模最大的裁员,预计全球将有高达3万人卷铺盖走人,包含美国、印度、加拿大与墨西哥都受到影响。
员工收信崩溃:连人资都没见到
根据《Washington Times》报导,许多员工在清晨6时许就收到来自甲骨文领导层的解雇邮件,内容中指出“由于组织调整,你的职位已被取消”,且当天就是最后一个工作日。不少苦主在社群论坛Reddit和Blind哀号,表示完全没有预警,甚至连跟主管、人资(HR)说再见的机会都没有,公司帐号权限在几分钟内就被锁死,有员工不舍直言,“没有面谈、没有电话,只有一封Email,我们就被踢出去了。”
砍掉3万人冲刺AI?
至于甲骨文这波裁员到底规模多大?虽然官方目前闭口不谈,但投资银行TD Cowen估计,这波裁撤人数可能落在2万到3万人之间,相当于全球总员工数的18%。根据内部流出的消息,这次影响主要集中在营收与健康科学部门以及SaaS虚拟营运服务,裁员比例甚至高达30%。外界分析,甲骨文之所以对老员工痛下杀手,是为了省下约80亿至100亿美元的现金流,全力冲刺AI数据中心。
事实上,甲骨文为了建设支撑AI运算的大型设施,在过去两个月内已经扛下580亿美元的新债务,甚至有报导指出,甲骨文与Open AI合作、耗资高达5000亿美元的“星际门(Stargate)”数据中心计划,正陷入筹资困境。尽管甲骨文上一季净利暴增95%,狂赚61亿美元,但投资人显然不买单,由于市场担心AI会取代传统软件,甲骨文股价今年已重挫近30%,比起2025年9月的高点,市值更是直接腰斩。
科技业裁员潮恐还没结束
今年以来,科技业裁员浪潮不断,包括亚马逊裁撤1.6万人、微软砍掉1.5万人,Meta上周也传出裁员数百人的消息,其中甲骨文在最新的财务报告中透露,已经编列了21亿美元的重组计划预算,其中大部分将用于支付员工的资遣费。
