S&P 500 (sometimes the past...comes back...):

from the high of January 4, 2022 to today's low:= -27.5%

practically similar to the period: 1980-1982 (see image), but it could fall as low as -28% (3469), or as low as -28.5% (3445),
so if it were to rise sharply from any of these 3 levels, then perhaps (maybe) the minimum might have been reached;
if, on the other hand, it were to fall further, it could reach -33.5% or -33.9% (as in 1987 or 2020)
