Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.

Selling streak — 2 quarters in a row: For 2 consecutive quarters, more hedge funds reduced or closed their ATMC positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
Heavy selling pressure — only 0% buying: Last quarter: 10 funds sold vs only 0 buyers. This is widespread institutional distribution — not a few funds rebalancing, but a broad exit. High conviction bearish signal.
