Edit: provided I have understood correctly that you want to use your VIAC account for stocks only, as part of the stocks allocation of your permanent portfolio, you can use the CSIF SMI, CSIF SPI Extra, CSIF World ex CH - Pension Fund Plus, CSIF World ex CH Small Cap - Pension Fund and CSIF Emerging markets funds to build up a worldwide cap weighted allocation, or tilt it in the ways you want with potentially other funds.
