How to Read Stock Sentiment Scores: A Practical Guide to the Whisper Index

A stock sentiment score is a numerical representation of the aggregate mood and conviction of investors discussing a particular stock across social media, financial forums, and news sources. Unlike a simple mention count or thumbs-up/down classification, a sophisticated sentiment score incorporates linguistic analysis, argument quality, cross-platform consistency, and conviction intensity. StonkWhisper's Whisper Index is an example of such a composite score, designed to give traders a single number that summarizes the directional conviction of the retail investor community on any given stock.

The Whisper Index runs on a 0-100 scale. Readings above 70 indicate strong bullish conviction — a substantial majority of retail discussion is directionally bullish and showing high confidence language. Readings below 30 indicate strong bearish sentiment. Readings between 40 and 60 indicate neutral or mixed sentiment where no clear directional conviction exists. The most actionable signals typically come from extreme readings (above 80 or below 20) or from rapid directional shifts in the score.

Context matters enormously when reading sentiment scores. A Whisper Index of 75 on a stock that has already risen 40% in the past month carries different signal value than a 75 reading on a stock that has been range-bound for six months and is starting to attract attention. StonkWhisper displays the Whisper Index alongside price trend, volume trend, and mention velocity to provide this context. A rising Whisper Index on increasing mention volume on a flat price chart is a classic accumulation signal.

Sentiment score divergences are particularly valuable. When a stock's Whisper Index is rising (increasingly bullish sentiment) but price is flat or falling, it can indicate that the retail community is building conviction ahead of a price move — particularly if the divergence coincides with insider buying or dark pool accumulation. Conversely, when price is rising but the Whisper Index is falling (weakening sentiment), it may indicate the rally is losing its retail support base and is vulnerable to a reversal.

The practical workflow for using the Whisper Index: start with scores in the extreme range (above 75 or below 25) as your attention universe. Then filter for stocks where the sentiment trend (direction of score change over the past week) aligns with the score level — a score of 80 that's been rising is more interesting than a score of 80 that's been declining. Finally, cross-reference with dark pool data and institutional flow to confirm the setup.
