On March 30, according to MarketWatch, JPMorgan's Hedged Equity Fund is set to reset its positions on March 31, raising concerns that the S&P 500 may face significant volatility this week. The fund employs a put-spread collar options strategy to protect against downside risk while capping upside potential. The current key strike price is 6475 points, which creates a 'kryptonite effect' on the market—repelling prices from both above and below this level. As of last Thursday, the S&P 500 had fallen below 6475 points and accelerated its sell-off. With the quarterly reset approaching, analysts believe this may trigger passive selling in the short term, leading to a 'disconcerting' gradual decline. After the new positions are established, volatility is expected to gradually ease.
