How to Read a 13F Filing
A 13F becomes much more useful when every field is read in context. The key is to separate what the filing reports from what you might infer from it.
1. Check the report period
The report period tells you the portfolio date covered by the filing. It is not the same thing as the date the filing was submitted.
2. Read the reported value and position
Reported value and shares or principal amount describe the position reported for the security. RealitySeller keeps the source fields visible rather than manufacturing a trade price.
3. Check put/call and security type
Some reported positions are equity shares while others may be listed as principal amounts or options. The security classification changes how the position should be interpreted.
4. Treat filing changes carefully
A difference between two reporting periods can be a useful signal, but it is not a substitute for a transaction record. It should be described as a change in reported holdings unless a transaction disclosure independently supports more detail.
5. Open the source
For material decisions, verify the filing at the original regulator source.
