Absolutely, but if your are investing directly yourself through a stocks and share ISA then it makes sense to cash out every few years and reinvest In safer options and begin a new stock/share investment and run the cycle again. Of course if it’s your company/private pension then your options are more limited. But “generally” speaking it works well over a period of time and my point that it had risen significantly recently before falling away again was correct despite Brum Hatters comment below.
