I see much more value in this (Click on 'Timeline'):

edition.cnn.com - Fear and greed

Especially if you recalibrate their scale a little, keeping 0 as the low end of fear (=strongest buy signal), but cutting the upper end already at 75 as the most extreme greed (=strong sell signal).

Compare that with a 1 year S&P chart and be amazed:
- Every single time this index got close to the (recalibrated) scale's end for extreme greed of 75 it was a precious signal to sell.
- Every single time it got close to the scale's end for extreme fear of 0 it was a perfects signal to buy.

I know of only one equally great signal this year: Jim's Major bottom indicator which signaled on Sep 29 --- which was perfectly in line with this index having been in the 'Extreme Fear' zone then (resulting in me having done heavy buying that day).
