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.

Buying streak — 1 quarter in a row: For 1 consecutive quarter, more hedge funds added MDB 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 — 57% buying: Last quarter: 525 funds bought or added vs 401 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.
Elite ownership — 54% AUM from top-100 funds: 70 of 865 holders are among the 100 largest funds by AUM, controlling 54% of total institutional value in MDB. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
52% of holders stayed for 2+ years: 456 out of 874 hedge funds have held MDB 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, MDB has moved -21.1% since the 2026 Q2 13F filing date (August 14, 2026), compared to -1.2% for the XLK sector ETF — an outperformance of -19.9%. Since the quarter end (June 30, 2026), MDB has gained +8.2% vs -1.5% for XLK. The stock is tracking its sector benchmark closely. The signal remains fresh and the entry point is still near the fund's implied reference.
