STOCK SELL-OFF NOT OVER, GOLDMAN TRADERS SAY Goldman Sachs warns that US stocks could face more selling this week, driven by trend-following funds known as CTAs, which have already hit sell triggers in the S&P 500. The bank estimates CTAs could dump up to $33 billion this week — and as much as $80 billion over the next month if the S&P 500 keeps falling. Even in a flat or rising market, these funds are still expected to sell. Market stress remains high, liquidity is thin, and options positioning (“short gamma”) could amplify price swings, making trading more volatile. Other systematic strategies, including risk-parity and volatility-control funds, also have room to reduce exposure if volatility stays elevated. With weak seasonal trends and retail investors showing signs of fatigue, Goldman says market turbulence is likely to persist.(*Walter Bloomberg)
