Woofun AI notes that Goldman Sachs Partner Mark Wilson identifies the current sell-off as primarily driven by crowded positions, concentrated leverage, and deleveraging rather than macroeconomic deterioration. The momentum factor for US stocks has retraced 28% from its peak, while the technology, media, and telecom sectors have dropped by 40%, marking the fastest and deepest retracement on record.

Specific market declines include a 27% fall in the KOSPI, a 25% retraction in US AI beneficiary stocks, and drops of 36% and 23% in global and European semiconductor stocks, respectively. High-beta momentum portfolio volatility is approximately 10 times that of the S&P 500 Index, with individual stock implied volatility reaching 2.8 times the index average. Wilson indicates that the unwinding process is nearing its end, though short-term catalysts for a market reversal remain absent.
