The market has experienced a rapid shift from extreme fear to greed within approximately one month, as indicated by the CNN Fear & Greed Index rising from extreme fear to a level of 71, just four points shy of extreme greed. This surge in investor optimism is also reflected in the total put-to-call ratio, which has plunged to 0.55, the lowest since December 2010, and even down to 0.41 according to some sources. The S&P 500 has risen about 22% since its low on April 7 and continues to show gains. Market volatility has collapsed, and bullish sentiment has returned strongly, with investors increasingly confident despite questions about fundamental changes driving this rapid recovery. The swift transition from fear to greed is considered one of the fastest in market history, with some analysts noting the current environment as a continued melt-up phase. Insider buying activity has also been noted during this period of heightened market enthusiasm.
