Trying to time when financial markets will go up or down is about as useful as betting your retirement money on a pair of dice. I’ve been a critic of this pseudo-science all of my life. However, there is one type of market timing that I agree with. It’s call secular market timing. The word secular is derived from the Latin word saecularis meaning of a generation, belonging to an age. A secular market includes many bull and bear markets within in one large generational move, in which valuations move from one extreme valuation to the other. These peaks and troughs occur over the long term, 25- to 35-year periods on average.
