The 13(f) securities list — what counts as a 13F holding?
TL;DR
Not every asset a hedge fund owns shows up on a 13F filing. The SEC publishes a quarterly Official List of Section 13(f) Securities defining which securities trigger reporting: sec.gov/divisions/investment/13f/13flist.txt. Roughly 17,000 securities — all U.S.-exchange-listed equities, ADRs, certain convertibles, certain ETFs, and a small set of options. Everything off this list is off-13F and invisible to retail readers tracking smart money.
Section 13(f) of the Securities Exchange Act of 1934 — enacted in 1975 — applies only to a defined universe of securities. The SEC publishes that universe quarterly as the Official List of Section 13(f) Securities, and managers' reporting obligations are precisely scoped to that list.
What's on the list
- U.S. exchange-listed common stocks (NYSE, Nasdaq, Cboe Equities) — the largest category, ~9,000 entries
- American Depositary Receipts (ADRs) — foreign stocks held via U.S. depository banks
- Certain convertible debt — corporate bonds convertible into 13(f)-listed equity
- Closed-end fund shares — equity-traded RICs (not the underlying fund holdings)
- Certain ETFs — exchange-listed shares of registered investment companies (NOT the underlying fund positions; the ETF share itself)
- Equity options — listed equity options on exchange-traded options markets; reported notionally as the underlying equity exposure
- Equity warrants and rights — when traded on registered exchanges
What's NOT on the list
Excluded categories are large, and they shape what 13Fs can and cannot tell you:
- Short positions — invisible. A fund could be net-short Apple and show it as a long position on 13F.
- Non-U.S.-listed equities — foreign stocks bought directly on London or Tokyo exchanges are excluded.
- Bonds (corporate, treasury, agency, municipal) — bond positions don't show up. A fixed-income hedge fund could be invisible.
- Most derivatives — futures contracts, total-return swaps, OTC swaps, and most options are excluded. A fund with synthetic exposure to AAPL via a TRS shows nothing on 13F.
- Cash and cash equivalents — not on the list.
- Private placements, private equity, real estate — entirely outside the regime.
- Cryptocurrency — bitcoin, ether, etc. are not 13(f) securities (BTC futures on CME are; BTC spot ETFs registered as ICs are on the list).
Why this matters for reading 13Fs
Three consequences for the practical reader:
- The 13F you're reading is incomplete by design. A fund with 60% gross exposure to U.S. equities + 40% to bonds shows 60%-of-portfolio on 13F. Don't mistake the 13F view for the full book.
- Short-biased funds look long-only on 13F. A market-neutral fund with $10B long + $10B short shows the $10B long as if the fund were directionally long-only. The hedge invisible.
- Cross-asset funds look smaller than they are. A multi-strategy fund with $50B AUM might show $15B on 13F because the rest is bonds, commodities, currencies, alternatives. The 13F filing is not the AUM.
Our view
The 13(f) securities list is one of the structural facts that makes 13F-based research work the way it does. Every position you read on HoldLens is necessarily in 13(f)-list scope — that's why we can compare across managers consistently. The flip side is that positions OUT of scope (shorts, bonds, derivatives, non-U.S.) are invisible to this analysis entirely.
For tracked-superinvestor reading, this means: 13F is the right tool for value-style long-only U.S. equity exposure (Buffett, Klarman, Burry on the long side, Greenblatt, Pabrai). It is NOT the right tool for fixed-income arbitrage, global-macro, derivatives- heavy strategies, or short books. Pick the right manager for the right reading.
