Due to factors such as U.S. economic data falling short of expectations and persistent inflationary pressures, U.S. stocks have fallen below key support levels, triggering a sell-off?
Just two days ago, the S&amp;P 500 index had fallen below the 50-day moving average (and the 100-day moving average), and at one point approached the short-term CTA (Commodity Trading Advisor) trigger level of 6045 points, which means that the CTA, which was originally extremely bullish on stocks, will begin to sell.
With overnight U.S. stocks being severely impacted by tariff threats, the S&amp;P 500 index closed down 1.6%, at 5861 points, falling below the more important mid-term CTA trigger level of 5887 points.

Morgan Stanley's quantitative and derivatives strategy team pointed out that this means macro systematic strategies will sell over $40 billion in stocks within the next week, most of which will come from CTAs. Although there may be demand from pension/asset allocators of $10 billion to $15 billion by the end of the month to partially offset the selling pressure, overall market sentiment remains tense.
Morgan Stanley also stated that traders' long option Gamma positions have been reduced to low single digits (calculated per 1% change), indicating a significant reduction in their call option holdings and a corresponding decrease in sensitivity to market volatility.
However, Morgan Stanley also added that due to the presence of zero-day option positions, if the market continues to sell off, traders will increase hedging operations, leading to a short-term increase in Gamma positions, thereby slowing the pace of the market decline.
After Morgan Stanley issued a warning email, the market sell-off did not slow down but rather accelerated. Some analysts pointed out that unless a strong reversal occurs, institutional investors may join retail investors in the sell-off, further exacerbating the market decline.
