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 2026-07-31This 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.
Computed by this site from the fund's SEC Form N-PORT filing; what the measure does not tell you · every fund in one table · hold it with other funds? X-ray the mix. Pricing: 13.68% at a quoted market price (level 1), 17 issuer countries.
What stands out
as of 2026-07-31The largest line in COMT's filing is not a stock but BlackRock Cash Funds: Treasury, SL Agency Shares, a short-term position at 15.57% of net assets. Between the 2026-01-31 and 2026-04-30 filings 85 positions were added and 74 dropped; 62.5% of the weight moved. the United States is the largest country at 64.27% of the portfolio, across 17 countries in the filing.
Each sentence is read from the fund's own SEC filing; the class median is computed across the comparable short-term funds on this site. Nothing here is a view on the fund.

Returns the fund reported
2019-08 – 2026-04Monthly total returns from Item B.5 of COMT'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 0.19 percentage points over 81 months, which is roughly the distributions. Every month with the filing it came from: COMT.json · all funds.
Who borrows COMT's shares
2020-01-31The 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.
| Borrower | On loan | Share 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 → 2026-04-30140 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.

Asset categories and pricing
as of 2026-07-3196.67% 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 2026-04-30A 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.
