iShares Technology Opports Act ETF SEC Filings

BlackRock ETF Trust – iShares Enhanced Short-Term Bond Active ETF submitted a routine Form N-PORT for the period ended 30 April 2025. The filing shows total assets of $96.89 million, offset by minimal liabilities of $32 k, resulting in net assets of $96.86 million. Cash and cash equivalents not otherwise classified amount to $122 k.

Portfolio risk metrics indicate limited duration and credit exposure: a 1 bp parallel shift in rates (DV01) would change value by $771 at the 3-month tenor and –$1.77 k at 1-year; a 100 bp shift (DV100) would move the same tenors by $39.34 k and $4.71 k respectively. Credit-spread sensitivity remains modest, with investment-grade CS01 of $449 at 3 months and high-yield CS01 of $77.

The ETF reported three consecutive positive total-return months of 0.30%, 0.33%, and 0.33%. However, derivatives activity produced realized losses and unrealized depreciation in both foreign-exchange forwards and interest-rate futures, with cumulative unrealized FX losses exceeding $118 k across the first two months.

No borrowings, preferred shares, or material off-balance-sheet leverage are disclosed, and securities-lending collateral was entirely cash. Management does not mark this as the fund’s final N-PORT filing.

BlackRock U.S. Carbon Transition Readiness ETF (Series ID S000071281, CIK 0001761055) filed its monthly Form N-PORT for the period ended 30 April 2025.

The fund reported $1.152 billion in total assets and $1.146 billion in net assets, with liabilities of just $6.45 million (≈0.6 % of assets), indicating a conservative balance sheet. Securities-lending exposure is modest at roughly $2.9 million (≈0.25 % of net assets) across six prime brokers, led by Barclays Bank PLC.

Performance was weak: three-month total returns were -1.74 %, -6.16 %, and -0.65 %. Equity futures produced realized losses of $551 k in Month 2 and cumulative unrealized swings (±$209 k). Non-derivative holdings showed sizeable unrealized depreciations of $35 m and $82 m in Months 1-2, outweighing realized gains. Cash and cash equivalents stood at $383 k.

No borrowings, preferred stock, or controlled-foreign-corporation assets were reported, and credit-spread risk metrics were blank, suggesting minimal fixed-income exposure. Overall, the filing shows a well-capitalised fund facing recent negative returns and valuation markdowns.

BlackRock ETF Trust – iShares A.I. Innovation and Tech Active ETF (Series ID S000086268, LEI 529900A898KGKVGZQ177) filed its monthly Form NPORT-P for the period ended 30 April 2025. The fund reported total assets of $138.66 million, offset by liabilities of $8.48 million, resulting in net assets of $130.18 million. No borrowing, preferred stock, delayed-delivery payables or controlled foreign corporation exposure was disclosed, underscoring a low-leverage balance sheet. Cash not otherwise classified totaled $3,482.63.

Performance: Monthly total returns for the last three months were -8.93 %, -14.68 %, and +3.40 %, reflecting elevated volatility. Realized and unrealized activity shows sizeable losses in Months 1-2 (realized losses of $0.91 m and $4.03 m; unrealized depreciation of $8.85 m and $10.95 m) followed by a reversal in Month 3 (realized loss $5.11 m offset by unrealized appreciation of $12.53 m).

Securities lending: Six counterparties held securities on loan totaling roughly $4.19 million, led by UBS AG ($1.58 m), Wells Fargo ($0.96 m) and Citigroup Global Markets ($0.76 m). The filing indicates non-cash collateral may have been accepted, but specifics were not provided.

Risk metrics: Item B.3 credit-spread risk fields were left blank, implying debt exposure below the 25 % NAV threshold. No derivatives data were supplied in Item B.5(c).

The registrant signals this is not a final NPORT filing. Contact and submission fields were blank, typical for automated filings.

The ETF remains small ($6 m net assets) and experienced material drawdowns in the first two reported months, partially offset by a recovery in Month 3. Absence of debt and modest cash reserves limit balance-sheet risk, while securities-lending activity provides incremental income but concentrates counterparty exposure.

BlackRock ETF Trust – iShares Long-Term U.S. Equity Active ETF (symbol: TEK) has filed its Form N-PORT for the period ended 30 April 2025. The Series discloses total assets of $6,772,041 against liabilities of just $18,221, leaving net assets of $6,753,821; leverage is therefore negligible (≈0.3% of assets).

Recent performance was mixed and volatile. Monthly total returns were -4.43%, -7.86% and +1.66% over the last three months. Realised and unrealised results reflect this pattern:

• Month 1: realised loss $51,524; unrealised depreciation $462,243.
• Month 2: realised loss $404,596; unrealised depreciation $467,763.
• Month 3: realised loss $203,825; unrealised appreciation $17,957.

Risk and balance-sheet profile. The fund reports no borrowings, preferred stock, delayed-delivery payables, or controlled foreign corporation exposure. Securities-lending activity is noted but the collateral type is not specified. Cash and cash equivalents outside Parts C and D are reported at zero.

Other disclosures. Flow information, derivative breakdowns, and a final-filing indication are left blank, limiting insight into shareholder activity and future reporting status.

In sum, TEK remains a small, unlevered portfolio that experienced two materially negative months before a modest rebound in the latest month.
