Tactical asset allocation cannot be employed consistently

I personally feel that tactical asset allocation cannot be employed consistently for most parts of the market.  

However, this strategy can probably can be employed rationally at certain times when the market were obviously undervalued (1997/98, 2008/2009) or when it was highly overvalued  (bubble  in 1996/97). 

Therefore, in the long investment period that you are in, it is the rare occasions when you will be fully invested (80% equity:20% cash) or fully out of (50% equity: 50% cash) the market.  (My own asset allocation figures  ).  

Did you feel that the market was a bubble in 2008?
