Alpha Cloning — Following 13F Filings
Copy (with a lag) the disclosed long holdings of selected 13F filers — a delayed clone of someone else’s book.
Definition
Alpha Cloning — Following 13F Filings refers to a delayed clone of someone else’s book. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
It is a named object desks use to frame risk, positioning, or process. When a delayed clone of someone else’s book shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what alpha cloning — following 13f filings is saying. If a delayed clone of someone else’s book moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Keep the definition fixed, then challenge it with cross-checks before sizing. Prefer a short written null hypothesis for Alpha Cloning — Following 13F Filings: what would falsify the current reading in the next window?
