It is an important question how asset price growth stimulates the economy. It certainly does, based on the relationship between boom bust cycles, observed
in 1929, 2008, etc. I agree it is not obvious how. During the housing boom, the assumption of perpetually rising prices made people willing to increase credit and spending. I think it might have been similar in 2000 and 1920s: the rising asset prices made debt increase possible, as GRG says.
