How to interpret index sentiment
Read the direction, participation, and history of the conversation together, then compare the social move with price and market events.
Bullish, bearish, or neutral
Nebula classifies the stance of relevant index conversation instead of treating every mention as an expression of conviction.
Participation gives the score weight
Post counts and conversation balance stay visible so a broad change in tone is not confused with a small burst of commentary.
Direction matters more than one point
Use the historical view to see whether sentiment is strengthening, weakening, or reversing across the selected timeframe.
Breadth changes the meaning
Compare index-level tone with constituent breadth and sector leadership to see whether the mood is broad or concentrated.
Investigate the index conversation
Compare one benchmark with the S&P 500 sentiment tool and use the stock-index sentiment guide to investigate breadth, constituent tone, sector leadership, and concentration.
