The massive net selling by mega-passive funds (Vanguard, Fidelity) and quant funds (D.E. Shaw) suggests a structural de-rating thesis, possibly tied to ADR de-listing risk or deteriorating fundamentals. Monitor upcoming earnings for revenue/guidance confirmation and watch for any insider buying to counter the institutional exodus.
Executive Summary
Hesai Group saw a mixed institutional cluster in Q2 2026: 23 buyers added $32.7M in new holdings (led by JPMorgan, Nordea, and Goldman Sachs), while 16 sellers reduced positions by $152.0M, driven by massive exits from Vanguard (-$70.8M), Fidelity (-$35.5M), and Wellington (-$27.7M). The net selling pressure of ~$119M from mega-passive and quant funds far outweighs the buying, signaling broad institutional de-risking despite some active manager accumulation.

Key Facts
- 23 institutional buyers added $32.7M in net new holdings; 16 sellers reduced by $152.0M, for a net negative of ~$119M

- Quant funds D.E. Shaw and Millennium trimmed 74.1% and 33.8% respectively, removing $10.3M in combined exposure
- The cluster is dominated by mega-passive sellers (Vanguard, Fidelity, BlackRock) vs. a mix of passive and active buyers
Financial Impact
Net institutional selling of approximately $119M in Q2 2026, with total seller reductions of $152.0M versus buyer additions of $32.7M
Risk Factors
- Continued institutional liquidation could pressure the stock further, especially if passive index rebalancing is the driver
- The 45-day reporting lag means Q2 positions may already be stale; current quarter activity could differ
- No insider buying confluence to corroborate the buyer thesis — the sell-side signal dominates
