Quick Reference

A clarification on the two trim rows above: BNY Mellon genuinely reduced its NVDA and MU share counts, but the dollar value of each position rose because the stocks' price gains over the quarter exceeded the value of the shares that were sold -- neither row represents buying.

Q: Did Bank of New York Mellon buy or sell Nvidia (NVDA) in Q2 2026? Bank of New York Mellon sold Nvidia (NVDA) in Q2 2026, actively trimming the position instead of adding to it. The stake's dollar value nevertheless rose from $26.82B to $30.45B (+$3.63B) because the stock's price gained more than the trimmed shares were worth, and its portfolio weight ended the quarter at 5.00%, up from 4.93%.

Q: Why did BNY Mellon's Micron (MU) position gain value while the fund was selling shares? The value rose because Micron's share price gained more than the trimmed shares were worth, so the price move outran the genuine reduction in share count. In dollars, the position went from $2.51B to $8.25B (+$5.73B), lifting its portfolio weight from 0.46% to 1.35% even though BNY Mellon held fewer MU shares at quarter-end.

Q: What is Bank of New York Mellon's biggest holding after the 2026-Q2 13F? Nvidia (NVDA) is the largest position disclosed in the filing, worth $30.45B and representing 5.00% of the portfolio -- a stake BNY Mellon trimmed even as its price-driven value climbed. Microsoft follows as the next-largest line at $19.95B, and Microsoft is one of the names the fund actively added to during the quarter.

Q: Did BNY Mellon completely exit any major position in Q2 2026? Yes -- the fund sold out of Honeywell (HON) entirely, taking a stake previously valued at $1.43B (0.26% of the portfolio) down to zero. Honeywell was the only full exit among the quarter's largest position changes.

Q: What new position did Bank of New York Mellon open in Q2 2026? The filing's headline new buy is reported under the identifier 438516205, a brand-new position valued at $732.9M and equal to 0.12% of the portfolio. Unlike every other increase this quarter, this line had no footprint in the prior-quarter filing, which makes it a true initiation.

Q: Which semiconductor and hardware stocks did BNY Mellon add to in Q2 2026? Within chips and data-storage hardware, the fund built up Marvell Technology (MRVL), KLA (KLAC), Western Digital (WDC), and Seagate (STX). Marvell posted the largest build, rising to 0.39% of the portfolio (+$2.06B), with additional builds at KLA (+$1.21B), Western Digital (+$1.18B), and Seagate (+$826.6M).

Q: How did the size and activity level of the portfolio change in the quarter? The position count expanded to 4274 holdings from 4175, and the turnover ratio rose to 0.217952 from 0.186535. Concentration (HHI) ticked up to 0.009875 from 0.009731, the momentum tilt widened to 0.012193 percentage points from 0.006385, and information technology remained the largest sector allocation.

Q: Which other large stakes did BNY Mellon trim besides Nvidia and Micron? The fund also trimmed Apple (AAPL), AMD, Intel (INTC), Broadcom (AVGO), both Alphabet share classes (GOOGL and GOOG), Eli Lilly (LLY), Cisco (CSCO), Caterpillar (CAT), Exxon Mobil (XOM), and Chevron (CVX). Share counts fell across every one of these lines, making trimming the dominant action among the filing's largest position changes.

Q: What's the easiest way to track Bank of New York Mellon's future filings? The easiest way to follow the fund going forward is to check its next quarterly 13F with the SEC, which is due roughly 45 days after the close of each quarter and will refresh share counts, dollar values, and any newly reported identifiers such as 438516205. Setting this 2026-Q2 disclosure as the baseline makes each subsequent round of adds, trims, and exits straightforward to spot.
