Options in 13F: The Distortion Problem

Back to Tutorial

Many 13F websites blend equities and options into a single portfolio percentage. This is simple, but can be misleading.

In SEC 13F reports, option rows (PUT/CALL) are reported with underlying exposure values, not premium cash paid/received.

What BLARKAD changed

  • Sector and industry trend analytics are equity-focused (SH, no PUT/CALL).
  • Holdings % weighting is bucketed to avoid options-driven distortion.
  • Instrument charts explicitly label exposure context.

How to read the data

  • Use Trends/Sectors/Industries/ETF views for equity rotation analysis.
  • Treat options values as SEC-reported exposure, not premium cash deployment.
  • Use instrument mix charts to evaluate exposure composition.

Why numbers can differ from other platforms

BLARKAD favors defensible methodology and explicit labeling over visually inflated single-percentage portfolio views.
