Measured concentration

Read this figure with the following in mind

3.4% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 123.7

The figure below is what the filing says, published unchanged. What it may not do is sit beside a plain long-only fund and be read as the same quantity. How comparability is decided.

As filed, collateral included

3.43% collateral

MDYG's filing lists 246 positions including 3.43% of net assets in securities-lending cash collateral. Counted as filed the fund reads 123.7 effective holdings with a top ten of 16.54%; on its own investments — the figure above — it reads 144.6 with a top ten of 14.43%. The collateral is matched by a liability and is not a holding the fund chose; since 2026-09-18 every figure on this site sets it aside (methodology). Both numbers are in the data.

Who borrows MDYG's shares

2026-06-30

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $231m was out to 21 borrowers, 7.89% of net assets. The largest, BARCLAYS BANK PLC, held 54.9% of it.

BorrowerOn loanShare of the loan
BARCLAYS BANK PLC $127m 54.9%
CITIGROUP GLOBAL MARKETS INC. $36m 15.7%
BofA Securities, Inc. $16m 7.1%
MORGAN STANLEY & CO LLC $11m 4.9%
Wells Fargo Securities LLC $5m 2.3%

Cash collateral reported against the loan: 3.43% of net assets, 43.5% 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 MDYG has filed, with each borrower: MDYG.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

243 positions became 244: 6 added (4.4% of the fund at the later date), 5 dropped (3.5% at the earlier date). Half the sum of all weight changes, a turnover proxy: 12.6%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.
