according to my valuation, their offer is closest to the low cost index fund investment popular among mustachians. VZ had a similar offer before, but with max. 80% stocks, lots of currency hedging, and a bit more expensive in fees. after that come the swisscanto passive funds. MP made a blogpost about it.
everything after that (UBS/CS funds, life insurances, cash depots) are somewhere between worthless, ripoff and scam. see this as bad example
