According to Fisher Investments, they only had one client and managed $2M in assets in 1995. Please allow me to congratulate you, if your family was in fact that one client! But it sounds like you started with $2M and not $1M, which would imply a very mediocre 7% average annual return. Also, Fisher Investments performance when they had $2M under management is of little relevance now that they reportedly have 20,000 times that amount to manage and thousands of clients. The ballgame is quite different now.

P.S. The link you provided reads like a promo piece for FI. It is an article in an industry magazine whose sole business it is to advertise investment advisers. How can you expect them to provide impartial information on their advertisers? In any case, there is no discussion of unhappy clients - only the company claim that their termination rate is very low.
