Market Sentiment Check: Greedy or Fearful?

You know the saying - 'Be greedy when others are fearful" - but I'm now wondering how quickly the speed of a rebound like last night/this morning (taco strikes again lmao) would cause a significant shift in market psychology. [CNN's fear and greed index](https://www.cnn.com/markets/fear-and-greed) was on the edge of Extreme Fear (score of 22 last i checked) and I think it will move up squarely into the Fear territory after markets open when VIX and other components are factored in. And emotionally, seeing that dramatic move up in my portfolio last night in the final hour of after-market and that gap up sustaining this morning in pre-market makes me think investors broadly won't be holding that fearful sentiment much longer. I wouldn't be surprised if it just kept rolling all the way up into Neutral by today's market close - assuming the gap up this morning pre-market sustains through the trading day - but not sure if it's even possible or ever been done. Would love to hear your thoughts (just opinions, not advice): How quickly have we seen the Index pivot from 'Extreme Fear' to 'Neutral' in past volatility spikes? Does this feel like a sentiment bottom, or just a technical gap-up?
