Audio and video are produced for every briefing. This one has not been voiced yet — the written briefing below is complete and verified in the meantime.
Nasdaq ISE has filed a proposed rule change with the SEC to allow $0.50 strike price intervals on options over a select group of highly liquid ETFs priced below $100, for expirations between one and nine months out. The filing is open for public comment and sits with the Commission for approval. It matters to options market makers, listing desks and anyone building multi-month ETF hedges.
- The proposal permits $0.50 strike intervals for options on ETF Qualifying Securities where the strike is below $100, for expirations more than one month and less than nine months from expiry.
- Eligibility is restricted to ETFs meeting the Qualifying Securities criteria: AUM above $50 billion or $25 billion, specified monthly options volume thresholds, a position limit of at least 250,000 contracts, and participation in the Penny Interval Program.
- Series listed at $0.50 intervals may remain if an ETF later fails the criteria, but no additional such series may be listed until it re-qualifies, with eligibility reassessed each calendar quarter.
- Separate amendments clarify that Table 1 symbols trade their Short Term Option Daily Expirations regardless of Qualifying Securities status, while Table 2 expirations apply only in quarters a security qualifies; ISE states this does not substantively change the rules.
- Comments are due 21 days after Federal Register publication, and the SEC must approve, disapprove or institute proceedings within 45 days, extendable to 90.
