Reddit is where a large share of retail conviction forms in public. Communities like r/wallstreetbets, r/stocks, and r/options generate a continuous stream of opinion that, scored carefully, becomes a leading read on which names retail traders are crowding into.
The challenge is signal-to-noise. Reddit is sarcastic, meme-heavy, and gameable — naive keyword scoring is easily fooled by irony or coordinated hype. Reliable Reddit sentiment requires a model that understands tone and context, plus volume normalisation so a quiet ticker is not over-read on a handful of posts.
Reddit sentiment is most useful in combination. On its own it can be a contrarian indicator near extremes; confirmed by rising news tone and search interest, it is a momentum signal. The crowd is sometimes early and sometimes the last to know — context decides which.
Sintinel ingests and scores Reddit activity as one weighted input into the composite sentiment score, never as the whole picture.
