As of Jun 30, 2026 quarter end · 13F disclosures lag ~45 days — long positions only, tracked filers only.
Among 11 institutional filers, five trimmed Robinhood and only three added as of the June 30 disclosures, with Renaissance Technologies, Millennium and Two Sigma all cutting sharply while ARK Invest stayed the anchor holder. Those filings are roughly 45 days stale and predate the quarter being reported tonight, so they say nothing about where these funds sit now, but the group went into the back half leaning lighter rather than heavier.
