Are you asking about what investment strategy to choose at VIAC/finpension? Or is something else unclear?
For a 100% equity strategy, this thread may be useful:
Depending on your age, risk tolerance and investments outside pillar 3a, you may want to invest in less than 100% equity. The same applies if your pillar 3a investment horizon is shorter than usual (e.g. if you’re planning to withdraw your pillar 3a to buy a house).
