* Explain how contrarian investors can potentially use the FGI:

* Identify buying opportunities during periods of "Extreme Fear" when the market might be oversold.

* Exercise caution during "Extreme Greed" as it might indicate an overbought market primed for a correction.

* Emphasize the importance of combining FGI with technical and fundamental analysis for a more comprehensive market assessment.

Additional points to consider:

* Include a visualization of the FGI historical data to illustrate market sentiment trends.

* Briefly mention alternative market sentiment indicators for a more holistic view.
