TUNIU CORP

Tuniu Corp's 18 tracked institutional holders show $6.2 million in total value, and more than 84% of it sits with four global banks — Morgan Stanley (50.5%), Goldman Sachs (15.3%), UBS (12.7%), and Bank of America (5.9%) — names whose 13F positions in a thinly-traded Chinese travel ADR are far more likely to reflect broker-dealer inventory and hedging books than genuine investment conviction. The payload itself flags several other holders explicitly by type: Dimensional Fund Advisors is tagged quasi_passive, Geode Capital Management is tagged passive_index, and both Jane Street Group and Two Sigma Securities are tagged market_maker — all four held roughly flat or added only modestly, consistent with mechanical index tracking and market-making rather than a fresh view on Tuniu. The one holder that made a real, sizable reduction is UBS, which cut its stake 52.6% (from 2,160,555 to 1,024,195 shares, -$550,914) — the largest dollar move in the dataset in either direction. Morgan Stanley and Goldman Sachs both trimmed shares modestly (-16.8% and -3.1%) but saw their position values rise anyway as the stock's price moved higher. Two small new holders, Baader Bank and Ground Swell Capital, opened token positions under $10,000 each.
