Methodology:
sector metrics are equities-only;

Why this matters.
How this table is calculated:
SEC
VALUE ($000) is used as reported.
For derivatives (PUT/CALL/WARRANT/RIGHT), SEC value represents reported underlying exposure, not premium cash paid/received.
Column % is bucket-based:
non-options share is calculated inside non-option total, options share is calculated inside options total.
