Looks? It's already in correction territory.
Tho amusingly folks talk about how the 1966-1982 period in the market may never happen again.
We are now in similar phase of the market cycle. 1960-1965 saw very very h ealth gains in the market, then it stagnated for the next 16 or so year while struggling with insane amount of inflation.
Will it happen again? No idea, but i do know for a mature market you don't pump more money and add to the deficit when the economy is good.
