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.
In 2026 Q1, 157 hedge funds were net buyers of ADPT (54 opened a new position, 103 added to an existing one), while 133 reduced or exited (94 trimmed, 39 sold completely) — a 54% buyer ratio, indicating a slight buying edge. This marks 7 consecutive quarters of net institutional buying — a persistent conviction signal. 30% of total institutional value in ADPT is held by top-100 AUM funds, reflecting strong institutional quality. Net fund flow last quarter: +15 funds (more new holders than closures). Total institutional holders: 293.

Signal Freshness measures how much ADPT has moved relative to its sector benchmark (XLV) since the 2026 Q1 13F filing. A stock that has barely outrun its sector is still a relatively fresh entry point — the fund's thesis has not yet been priced in by the broader market.
ADPT outperformed XLV by +21.9% since March 31, 2026.
Since the filing became public, ADPT outperformed XLV by +31.2% .
Interpretation: The stock has significantly outperformed its sector benchmark — the original entry opportunity has largely been captured by earlier investors. Learn more →

Buying streak — 7 quarters in a row: For 7 consecutive quarters, more hedge funds added ADPT than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.
Slight buying edge — 54% buying: Last quarter: 157 funds bought or added vs 133 that reduced or exited. It's nearly a 50/50 split — some institutions are convinced, others are taking profits. This mixed picture is normal near price highs.
Strong quality — 30% AUM from major funds: 54 of 293 holders rank in the top 100 by AUM, accounting for 30% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
54% of holders stayed for 2+ years: 159 out of 293 hedge funds have held ADPT for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.
As of today, ADPT has moved +37.2% since the 2026 Q1 13F filing date (May 15, 2026), compared to +6.0% for the XLV sector ETF — an outperformance of +31.2%. Since the quarter end (March 31, 2026), ADPT has gained +26.8% vs +4.9% for XLV. The stock has significantly outperformed its sector benchmark — the original entry opportunity has largely been captured by earlier investors.
