Is RxSight (RXST) stock Halal?

RxSight is a healthcare company specializing in the development and commercialization of innovative ophthalmic implantable devices. Its primary product line includes light adjustable lenses, which allow patients to adjust and customize their vision post-cataract surgery, enhancing visual outcomes. This ability to fine-tune vision is achieved using proprietary technology that utilizes ultraviolet light to adjust the lens power after surgical implantation and healing. Before any of that matters to a Muslim investor, one question comes first: is RxSight stock Halal?

Is RxSight Shariah compliant?

No. In the October 2026 screening RxSight (RXST) does not pass AAOIFI screening: it fails the interest-bearing investments screen. Healthcare rarely troubles the activity screen; treating illness is permissible work. For RxSight, the AAOIFI Shariah Standard No. 21 verdict turns on the balance sheet instead: research is capital hungry, and interest bearing debt and investments must each stay below 30% of market capitalisation.

Does RxSight pass the business activity test?

The activity screen is only part of the picture this month: RxSight currently fails the interest-bearing investments screen, so the overall verdict is not compliant regardless of the business itself. Treating illness is permissible work; the scrutiny belongs to the financing behind it.

Is RxSight's income Halal?

Yes, within AAOIFI's tolerance. RxSight's income from non-permissible sources stays below 5% of revenue in the October 2026 screening.

Does RxSight meet AAOIFI's debt and investment ratio requirements?

Not in full. Interest bearing investments currently exceed the 30% cap, measured against a market capitalisation of $204M (market data as of 1 October 2026), while the other ratio stays within it. One breach is enough to fail the screening; the ratios are reassessed monthly under our Shariah Supervisory Board.

Why do other halal screeners show a different verdict for RxSight?

Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.
