Monitor for any future JPMorgan 13D conversion if JPMorgan later files an amendment with activist intent; otherwise, this is a routine passive index holding. Monitor next quarterly for any material changes in stake or intent.
Price Chart
Executive Summary
JPMorgan Chase disclosed a 5.3% passive stake in REGENXBIO Inc. via a new SC 13G filing, confirming passive intent. This is a new filing from JPMorgan (not an amendment), adding to a series of passive 13G filings from other institutions (State Street, Vanguard) over the past year. The stake is modestly above the 5% threshold, indicating routine index or passive fund management rather than high-conviction.
