COMT holdings

COMT reports 160 holdings and behaves like 55.8 equally weighted ones, computed from its SEC Form N-PORT filing for 2026-07-31. The fact sheet publishes the first number; this page computes the second, and traces it across 27 quarters of filings.

Measured concentration

as of 2026-07-31

This figure is not comparable with other funds

swap and futures notional is 99% of net assets: the fund's exposure is delivered by derivatives, and a count of its filed positions does not describe it. See the exposure section for what the notional is written on

97% held in short-term investment vehicles: this is a cash-like fund, and its holding count measures something different

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.

Who borrows COMT's shares

2020-01-31

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2020-01-31, $11m was out to 11 borrowers, 2.20% of net assets. The largest, JP MORGAN SECURITIES LLC, held 52.7% of it.

BorrowerOn loanShare of the loan
JP MORGAN SECURITIES LLC $6m 52.7%
Wells Fargo Bank, National Association $2m 19.2%
CREDIT SUISSE SECURITIES (USA) LLC $964,619 9.1%
CITIGROUP GLOBAL MARKETS INC. $714,500 6.7%
BARCLAYS BANK PLC $490,025 4.6%

Cash collateral reported against the loan: 2.31% of net assets, 104.8% 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 COMT has filed, with each borrower: COMT.json · all funds.

Since the previous filing

2026-01-31 → 2026-04-30

140 positions became 151: 85 added (50.0% of the fund at the later date), 74 dropped (46.7% at the earlier date). Half the sum of all weight changes, a turnover proxy: 62.5%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of COMT compared this way, as a feed: changes.xml · all funds: filings received.

Asset categories and pricing

as of 2026-07-31

96.67% short-term investment, 3.33% DCO as filed; 13.7% 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 2026-04-30

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 $1.16B. Notional of an interest-rate or currency swap is not equity exposure.
