Similarities between recent market activities and september 1987

Is a market crash coming ? Rarely, in the last 30 years, have we had a US market price action (SP500) that similar to the days preceding the 1987 crash.

There is no certainty that history will repeat but it might useful to consider that it is at least a similar technical setup.

Time to be cautious on the long side, as long we don't make new highs.
