2026-Q1 BANK OF AMERICA CORP /DE/ 13F Filing: BofA buys $3.76B of AZN stock

Every quarter, institutional money managers with more than $100 million in equities must disclose their U.S.-stock holdings on Form 13F. This walkthrough uses Bank of America Corp.'s 2026-Q1 filing to show you exactly what to look for in these reports.

1. What a 13F filing discloses. A 13F provides a quarterly snapshot of an institution’s equity portfolio, including the number of positions and summary metrics. For Bank of America, the filing shows a holding count of 5689 and a turnover ratio of 0.158828, a direct measure of trading activity for the quarter.

2. How to spot a new position. The action field labels each change. A "new_buy" means the stock was not held the previous quarter. AZN is a new_buy with a current value of $3.76B. Since there is no prior value, this is a fresh addition.

3. How to read a trim vs. an addition. "Trim" and "add" both change the number of shares. MSFT was trimmed, reducing its value from $35.36B to $26.20B. IEMG was added, growing from $11.64B to $15.34B. Both are active decisions, not price movements.

4. How to read a full exit. A "sold_out" action means the position was eliminated entirely. AZNN previously held $2.42B and now has zero shares, representing a complete exit.

5. What the overall pattern tells you. The filing shows trims in large tech positions like MSFT, AAPL, and TSLA alongside additions to ETFs such as IEMG and VCIT and a new buy in AZN. This pattern highlights a rotation from individual equities toward diversified funds and a new healthcare bet.
