Exploitation risk from opaque and discretionary corporate action adjustments (especially derivatives)
Definition
While major public fraud cases are not widely documented for splits/dividends workflows, market makers highlight that opaque, discretionary handling of corporate actions in options and derivatives creates opportunities for unfair advantage and information asymmetry. Optiver notes that case‑by‑case exemptions and non‑transparent rules for how options are adjusted around corporate actions increase uncertainty and risk to investors in derivative securities[2].
Key Findings
- Financial Impact: Not explicitly quantified, but potential losses arise from mispriced options, widened spreads, and adverse selection borne by less‑informed participants when corporate action adjustments are unclear or applied inconsistently[2].
- Frequency: Event-driven but recurring (whenever complex actions affect listed options or derivatives)
- Root Cause: Lack of uniform, transparent decision rules and standardized language for how corporate actions impact listed options and other derivatives, allowing discretionary interpretations that can advantage some participants over others[2].
