After you stop working you can transfer your 2. pillar to two „Freizügigkeitskonti“. Swisscanto currently offers a fund with 75% stocks but TER plus account fees of the banks are quite high.
Offering a low cost solution would be a new business oportunity for someone like VIAC. Maybe the regulatory framework allows so,ething even closer to 100% stocks.
