IGM holdings

IGM reports 297 holdings and behaves like 25.9 equally weighted ones, computed from its SEC Form N-PORT filing for 2026-06-30. The fact sheet publishes the first number; this page computes the second, and traces it across 28 quarters of filings.

Measured concentration

as of 2026-06-30

Read this figure with the following in mind

1.3% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 25.8

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

1.26% collateral

IGM's filing lists 298 positions including 1.26% of net assets in securities-lending cash collateral. Counted as filed the fund reads 25.8 effective holdings with a top ten of 55.57%; on its own investments — the figure above — it reads 25.9 with a top ten of 55.57%. 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 IGM'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, $140m was out to 22 borrowers, 1.31% of net assets. The largest, UBS AG, held 34.6% of it.

BorrowerOn loanShare of the loan
UBS AG $49m 34.6%
JP MORGAN SECURITIES LLC $21m 15.0%
CITIGROUP GLOBAL MARKETS INC. $18m 12.7%
GOLDMAN SACHS & CO. $9m 6.8%
MORGAN STANLEY & CO LLC $8m 5.8%

Cash collateral reported against the loan: 1.26% of net assets, 96.1% 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 IGM has filed, with each borrower: IGM.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

289 positions became 297: 16 added (0.2% of the fund at the later date), 8 dropped (0.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 12.7%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

98.60% equity, 1.40% 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 2026-06-30

A 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 $10.71B. Notional of an interest-rate or currency swap is not equity exposure.
