UBS analysts, led by Nicolas Le Roux, identify option delta hedging and CTA flows as major price‑movement amplifiers driving volatility.
They note S&P 500 closed at 6,611.83 and could trigger buying pressure if it reaches the 6,950 technical level.
CTAs are positioned at 46% of maximum short capacity, remaining bearish after March equity sell‑off, while BofA reports continued CTA selling bias.
Gold and precious metals, which hit record highs pre‑Iran war, now see reduced CTA exposure as investors move to neutral.
