指数
Nasdaq CTA Cybersecurity Index(NQCYBR)
The Nasdaq CTA Cybersecurity Index™ is designed to track the performance of companies engaged in the Cybersecurity segment of the technology and industrial sectors.
The Index includes companies primarily involved in the building, implementation and management of security protocols applied to private and public networks, computers and mobile devices in order to provide protection of the integrity of data and network operations.
The Index began on June 23, 2015 at a base value of 1,000.00
To be included in the index, a security must be listed on an index-eligible global stock exchange and issued by a cybersecurity company that fits the classification of either Core or Complementary as determined by the Consumer Technology Association (CTA):
- Core: Cybersecurity companies that provide products, services, and/or solutions including application security, data security, endpoint security, identity & access management, networking security, and security observability.
- Complementary: Cybersecurity companies that offer products, services, and/or solutions including consultants, contractors, and managed service providers that implement cybersecurity solutions for clients, diversified technology providers, governance risk and compliance solutions, and security operations.
Eligible securities must meet size, float, security type and liquidity requirements. CTA then ranks securities based on their notional thematic revenue.
The top 50 Core companies with positive notional thematic revenue are selected. If there are less than 50 Core companies, the remaining positions are filled with top ranked Complementary companies.
The index employs a modified free float market capitalization weighting methodology.
The top 5 Core companies are capped at 8%, remaining Core at 4%, all Complementary are capped at 2%.
No security may be weighted less than 0.10%.
The index is rebalanced quarterly and reconstituted semi-annually.

博通
2019年，博通以 107 亿美元收购了全球网络安全巨头赛门铁克（Symantec）的企业安全业务，获得了 Symantec 旗下行业顶尖的端点安全（Endpoint Security）、数据防泄露（DLP）、网络安全网关（Web Security Service）以及身份验证等核心产品。
2023年末，博通完成了对全球虚拟化与云计算巨头 VMware（610亿美元）的巨额收购。
- 云安全（Cloud Security）：VMware 拥有著名的 Carbon Black（端点与云安全防护平台） 以及 NSX（软件定义网络与微隔离防火墙）。
- 零信任（Zero Trust）：VMware 的软件架构是现代企业搭建云原生安全和零信任网络架构（Zero Trust Architecture） 的基础设施底座。
除了软件，博通在传统半导体与网络芯片（如交换机芯片、路由器芯片、ASIC）领域占据垄断地位，提供具备 硬件级加密、数据包深度检测（DPI）、流量监控和防火墙加速功能的底层网络芯片，为企业数据中心和云服务商提供硬件维度的物理安全防护。
纳斯达克与美国消费技术协会（CTA）在编制指数时，采用 “名义主题营收（Notional Thematic Revenue）” 机制，尽管 Broadcom 也是半导体巨头，但其通过 Symantec + VMware 产生的网络安全业务绝对收入体量极高，在网络安全赛道产生的商业价值甚至超越了大部分中小型纯网络安全公司（Pure-Play）。
因此，按照 CTA 的行业分类标准，Broadcom 符合指数的入选资质，并成为 CIBR ETF 中的重要权重成分股。
