Long term saving: Shares, Savings Account or Fund
There is no rule of thumb (although some may suggest there is). Everybody will have different goals, investment preferences and risk tolerances. You need to figure this out by yourself by either education yourself in the type of investments you are interested in or by engaging (and paying for) a financial advisor. You should not be taking advice from others unless it is specifically geared for your goals, investment DNA and risk tolerance. The only advice I would give you is to have a plan (whether you develop it yourself or pay a financial advisor to develop one). Also, don't have all your savings sitting in cash, as long-term you will fall behind the eight ball in real returns (allowing for inflation).
