...a 30% plunge only takes the S&P500 to levels last seen in March 2023. Which actually does not make it such a big deal.
...it is more likely it will go to 5900-6000 and then fall -40% to complete a X-mas tree at 3,580 (level last seen in Oct 2022) or -31% to 4117. Not coincidentally, the last lows were seen in Oct 2023 (4117) and Oct 2022 (3,583). Sept-Oct are months typically ominous for markets.
