Returns the fund reported
2019-09 – 2026-05Monthly total returns from Item B.5 of MGV'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 0.04 percentage points over 81 months, which is roughly the distributions. Every month with the filing it came from: MGV.json · all funds.
Who borrows MGV's shares
2022-08-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2022-08-31, $32m was out to 4 borrowers, 0.55% of net assets. The largest, BARCLAYS CAPITAL INC., held 95.1% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BARCLAYS CAPITAL INC. | $30m | 95.1% |
| MORGAN STANLEY & CO LLC | $630,474 | 2.0% |
| GOLDMAN SACHS & CO. | $495,482 | 1.6% |
| Mizuho Securities USA Inc | $432,588 | 1.4% |
Cash collateral reported against the loan: 0.03% of net assets, 5.4% 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 MGV has filed, with each borrower: MGV.json · all funds.
Since the previous filing
2026-02-28 → 2026-05-31125 positions became 122: 4 added (1.3% of the fund at the later date), 7 dropped (0.4% at the earlier date). Half the sum of all weight changes, a turnover proxy: 9.6%.

Asset categories and pricing
as of 2026-05-3199.63% equity, 0.37% short-term investment as filed; 100.0% carried at a quoted market price (fair-value level 1). Categories and levels are the filer's; what a low level-1 share does and does not mean is in the measure's page.
Derivative exposure and counterparties
as of 2026-05-31A position count cannot describe a fund that uses derivatives, because a swap is filed at its unrealised gain, not its exposure. These are the notionals the fund itself reported, against net assets of $12.66B. Notional of an interest-rate or currency swap is not equity exposure.
| Swap counterparty | Notional | % of net assets |
|---|---|---|
| Bank of America NA | $41M | 0.33% |
| CITIBANK, NATIONAL ASSOCIATION | $5M | 0.04% |
| Goldman Sachs International | $2M | 0.02% |
Financing leg as filed: the fund pays OBFR01 + 0% on $48M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
