My first instinct is I want to see index ticker symbols overlaid on top of the sentiment chart to how well they do or don't correlate. Just showing periods of on/off correlation between tickers and sentiment in general would be an interesting visualization. Have you considered this?
The candlesticks do actually track the price data just like most stock charts. The purple line does however track the rolling sentiment, and the 'volume' bars represent the volume of bullish / bearish trades actually mentioned
My recommendation is take your data, find 10-years if you can, and then rank the top 100, or 500 stocks, I recommend 100. Now create a portfolio which rebalances itself monthly based on the sentiment from each network.
So you can have the WSB69, TWTR140, ST50, and such, to see which one is the most accurate. From my testing with sentiment analysis ages ago, I believe it doesn't work, but there are people who would jump onto those because it's fun for them.
So far it’s seems the most bullish sentiments are predicting the market incorrectly. I guess that’s why they say go against the popular sentiment on wallstreet bets.
The NLP I use is all custom and does a kind of hierarchical pattern matching. It identifies low level meaing and uses that as building blocks for higher level.
And yes it has been my observation that the market often reverses for the most popular plays
