The Short Answer
Keysight Technologies stock (KEYS) is generally considered halal by most Islamic scholars and Sharia screening agencies. Keysight makes precision instruments — oscilloscopes, signal analyzers, network analyzers, and software — used by engineers worldwide to develop and test electronics. This is neutral, enabling technology with no haram applications in Keysight's own business.
Keysight passes all Sharia financial screens with low debt and minimal interest income. It is one of the least controversial halal tech stocks available for Muslim investors.
Sharia Screening Methodology
Islamic scholars use several criteria to screen stocks:
- Business activity screen: Is the company's primary business halal?
- Debt ratio: Total debt / market cap must be under 33%
- Interest income: Interest income / total revenue must be under 5%
- Haram revenue: Revenue from haram sources must be under 5%
- Receivables ratio: Total receivables / total assets must be under 49–70% (varies by board)
What Keysight Technologies Does
Keysight Technologies (spun off from Agilent Technologies in 2014, which was spun off from Hewlett-Packard in 1999) is a global leader in electronic design and test instrumentation. Its two business segments are:
- Communications Solutions Group (~60% of revenue): Test solutions for wireless communications (5G, 6G research), network equipment manufacturers, data center networking, and aerospace/defense electronics. Products include signal generators, spectrum analyzers, and network test systems.
- Electronic Industrial Solutions Group (~40% of revenue): Test equipment for semiconductor manufacturing, automotive (EV battery testing, ADAS), general electronics manufacturing, and research universities. Products include benchtop instruments, oscilloscopes, and power analyzers.
In simple terms, Keysight makes the instruments that engineers use to measure, analyze, and verify that electronic systems work correctly. Without companies like Keysight, modern semiconductor chips, smartphones, 5G base stations, and electric vehicles could not be reliably developed and manufactured.
Financial Ratios (2025)
Based on Keysight's most recent financial statements:
- Total Debt / Market Cap: ~8% ✅ (threshold: under 33%)
- Interest Income / Revenue: ~1% ✅ (threshold: under 5%)
- Haram Revenue: None identified ✅
- Receivables Ratio: Within limits ✅
Keysight passes all Sharia financial screens with conservative debt levels and strong free cash flow generation.
Concerns to Be Aware Of
1. Defense and Aerospace Customers
Keysight sells test instruments to aerospace and defense customers, including US military contractors and defense agencies. Approximately 10–15% of revenue comes from this sector. Keysight sells measurement instruments — not weapons — and the same equipment it sells to defense customers is sold to telecom and semiconductor companies. The technology is neutral: an oscilloscope used to test a radar system is the same oscilloscope used to test a 5G base station.
Most Sharia scholars who review technology companies apply the materiality test: defense revenue under 5% is clearly fine; defense revenue that is the primary business is not. At 10–15% from a broad aerospace/defense segment (which includes civilian aerospace), Keysight is in a gray area that most screening agencies resolve in its favor.
2. Minor Interest Income
Keysight earns modest interest on its cash balance, representing approximately 1% of revenue.
Action required: Donate approximately 1% of any KEYS gains to charity as purification.
The Role of Test and Measurement in the Modern Economy
Test and measurement companies are the unsung enablers of the technology economy. The semiconductors in smartphones, the antennas in 5G towers, the batteries in electric vehicles — all must be designed, validated, and manufactured to precise specifications. Keysight's instruments make this possible. This is enabling infrastructure for beneficial technology, similar to how manufacturing equipment or precision tools are clearly permissible even though they can theoretically be used by anyone.
Verdict from Major Screening Agencies
Keysight Technologies stock is screened as compliant (halal) by:
- Zoya App — Compliant ✅
- MSCI Islamic criteria — Generally meets criteria ✅
- Most major Sharia advisory boards — Approved ✅
Bottom Line
Keysight Technologies (KEYS) is generally halal for Muslim investors. The electronic test and measurement business is entirely permissible, it passes all Sharia financial screens comfortably, and it has no direct haram revenue sources. A small purification amount for interest income is advisable.
KEYS is a high-quality industrial technology company with deep competitive moats — its instruments are deeply embedded in customer R&D workflows. For Muslim investors seeking halal exposure to the semiconductor and telecommunications supply chain without direct exposure to the chip manufacturing risks of companies like TSMC or Intel, Keysight is an attractive option.
