Fisher Investments Liars or incompetents or both? Woodside CA

My major question to Fisher Investments was:  What will you do if there's a sudden market downturn?  A number of strategies were outlined, but, when the 2008 economic disaster struck, they did exactly nothing.  Maybe the fact that they were making incredibly rosy economic forcasts had something to with their inertia.   Or, maybe they didn't know what to do is the answer.  Hence my conclusion that they're liars or incompetents or both.  

Also, considering our ages, they ignored the basic responsible investment strategy of dividing the investment portfolio up between equities and bonds.  Lost about 40% in the 2008 downturn.
