WT Asset Management Ltd
"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.
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. Buying this fund's new positions the day each filing went public, over 27 quarters, returned +10.8% per quarter versus +3.0% from owning every 13F stock, beating that baseline in 63.0% of quarters (excess t = 2.07, statistically significant). Caveat: across all 5,072 funds we tested, past performance shows near-zero persistence (rank correlation −0.018) — with thousands of funds, some will look significant by chance alone.
Quarterly compounding, invested quarters only · entry 47 days after quarter-end (when 13F data becomes public)

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.
