Largest TWST holders by dollars invested
Diversified funds ranked by how much TWST they own: assets under management times the TWST weighting. A broad index fund with a modest weighting often owns more TWST than every concentrated fund combined, so this order differs from the weighting table below. Leveraged and single-stock funds are left out because their reported weight is swap notional or a cash sleeve, not dollars of TWST.
