Returns the fund reported
2019-09 – 2026-05Monthly total returns from Item B.5 of TLH's own filings, 81 months on record. Not computed here and not from a price feed.
Cross-checked against a series computed separately from prices: median difference 0.07 percentage points over 81 months, which is roughly the distributions. Every month with the filing it came from: TLH.json · all funds.
Who borrows TLH's shares
2026-02-28The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-02-28, $2m was out to 1 borrower, 0.02% of net assets.
| Borrower | On loan | Share of the loan |
|---|---|---|
| GOLDMAN SACHS & CO. | $2m | 100.0% |
Cash collateral reported against the loan: 0.02% of net assets, 126.8% of the amount lent. That is a floor on the collateral, not the whole of it — collateral the fund does not hold as a position is not in this filing, so a figure under 100% is not evidence of under-collateralisation. How that figure behaves across all funds. Every quarter TLH has filed, with each borrower: TLH.json · all funds.
Since the previous filing
2026-02-28 → 2026-05-3168 positions became 67: 2 added (3.8% of the fund at the later date), 3 dropped (0.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 4.0%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of TLH compared this way, as a feed: changes.xml · all funds: filings received.
