Goldman Sachs has projected significant buying activity from Commodity Trading Advisors (CTAs) and corporate buybacks, estimating that CTAs will purchase approximately $86 billion in global stocks over the coming week, the highest estimate on record. This surge in buying is expected to occur under various market conditions, including flat, up, or down scenarios. Additionally, Goldman Sachs anticipates that U.S. stocks will rally over the next four weeks, driven by momentum traders and a robust corporate bid, with an estimated $10 billion in daily purchases from CTAs and corporate buybacks combined. Over the next month, total CTA demand could reach $138 billion globally. The firm also noted that volatility is stabilizing, which may contribute to the expected stock market rally, with the S&P 500 potentially hitting new highs in the coming months.
