"13F equity value" = market value of this filer's US-listed long equity positions only. It excludes cash, bonds, non-US and short positions, so it understates a fund's true assets under management — often by a lot.

Not significant Verdict

13F holdings are disclosed ~45 days after quarter-end, and they never reveal when within the quarter a fund actually bought. So any 13F-based summary is structurally late and blurred — this applies to every fund, including this one.

We backtested copying it anyway. Buying this fund's new positions the day each filing went public, over 20 quarters, returned +11.1% per quarter — versus +3.2% per quarter from simply owning every 13F stock. It beat that baseline in only 70.0% of quarters (excess t = 1.20, not statistically significant). Its filings tell you what it bought — not what you should buy.

New positions in 2026 Q1

Method & Limitations

Method: a "new position" = held this quarter, absent last quarter (options excluded; stocks with <50 prior holders excluded to filter spin-off artifacts). Entry 47 days after quarter-end — the first day the public could act on the filing. Benchmark = equal-weighted universe of all 13F-held stocks. Limitations: quarterly snapshots can't see intra-quarter trades; survivorship bias — funds that shut down are absent, which flatters the sample. Statistics, not advice.
