thanks for the clarifications:

then the easiest will be to create a row object that contains a flattened view of the data. This will make the template trivial.

public class FundStockRow {
    private Fund fund;
    private Stock stock;
    //constructor/getters
}

You then simply populate a flat ListModelList<FundStockRow>:

grid.setModel(new ListModelList<FundStockRow>(buildFlatFundStockRows(funds)));

and the template can look like this:

<grid>
  <template name="model">
    <row>
      <label value="${each.fund.name}"/>
      <label value="${each.stock.name}"/>
      <label value="${each.stock.price}"/>
    </row>
  </template>
</grid>
