The language of market attention.
Plain-English definitions for the stock, crypto, prediction market, and social-intelligence concepts used throughout Nebula.
Market intelligence signals
The shared language behind attention and sentiment research across markets.
Social Sentiment
The bullish, bearish, or neutral stance expressed in public market conversation. A useful sentiment model reads each post in context instead of treating isolated positive and negative words as a trading signal.
Mindshare
An asset’s share of relevant tracked conversation during a defined period. Rising mindshare means the asset is capturing more attention, but it does not reveal whether that attention is positive, informed, or durable.
Social Volume
The number of relevant posts, comments, or mentions about an asset or market theme. Sudden changes can surface a catalyst early, while consistently high volume may simply reflect an asset’s normal level of attention.
Narrative Rotation
The movement of market attention from one theme, sector, or group of assets to another. Researchers use rotation to identify where conversation is accelerating and then investigate the catalyst, participants, and price context.
Emotional Intensity
A measure of how strongly emotions such as excitement, confidence, anxiety, or panic appear in market discussion. Extreme readings can add context to a crowded narrative, but should be compared with volume and price behaviour.
Stock market terms
Core concepts for reading company-specific attention, tone, and catalysts.
Stock Sentiment
The aggregate tone of public conversation about a listed company or ticker. It is most useful when scoped to a clear time window and read alongside earnings, filings, news, price action, and the sources driving the change.
Stock Fear & Greed
A company-specific reading that combines social tone, attention, price momentum, volatility, and emotional intensity. Unlike a broad market index, it describes the current research context around one stock at a time.
Ticker
The short symbol used to identify a publicly traded security, such as NVDA for NVIDIA. The same company can have different symbols across exchanges, so a reliable research workflow also checks the company name and listing venue.
Catalyst
An event or development capable of changing expectations for a company, sector, or asset. Earnings, product launches, regulation, analyst actions, management changes, and macroeconomic releases can all become market catalysts.
Bullish and Bearish Stocks
A ranking of stocks by the positive or negative tone of their tracked conversation. These lists help researchers find unusual shifts, but strong sentiment is a starting point for investigation rather than a recommendation to buy or sell.
Crypto market terms
Language for market-wide emotion, token attention, and crypto-native participants.
Crypto Fear & Greed Index
A 0–100 score that summarises broad crypto market emotion from extreme fear to extreme greed. Nebula combines social sentiment and attention with price momentum, volatility, and emotional intensity to build its reading.
Crypto Market Sentiment
A market-wide measure of whether tracked crypto conversation is leaning bullish, bearish, or neutral. It measures public mood rather than price direction and can diverge from the market during fast-moving events.
Altcoin Season
A market regime in which a broad group of crypto assets outside Bitcoin gains relative participation or attention. Definitions vary, so every index should state its universe, methodology, thresholds, and measurement window.
Crypto KOL
A key opinion leader whose analysis, commentary, or audience can influence crypto attention. Reach alone does not establish expertise; source quality, conflicts, historical calls, and the accounts amplifying a narrative all matter.
Smart Money
A broad label for market participants considered informed or historically effective. Because the definition is subjective, researchers should check the exact inclusion criteria and avoid assuming that any wallet or account remains reliable forever.
Prediction market terms
The mechanics needed to interpret event-contract prices responsibly.
Prediction Market
A market where participants trade contracts tied to the outcome of a future event. Prices often resemble probabilities, but fees, liquidity, participant mix, contract rules, and market access can all affect that interpretation.
Event Contract
A contract that settles according to whether a defined event occurs. Its wording, deadline, data source, and resolution rules determine what traders are actually pricing, so the title alone is never enough.
Market-Implied Probability
The probability suggested by a contract’s current price after accounting for its payout structure. It reflects the market’s aggregate position at that moment, not an objective forecast or a guarantee that the event will occur.
Resolution Criteria
The written rules used to determine a prediction market’s final outcome. Good criteria identify the authoritative source, cutoff time, exceptional cases, and how ambiguous or delayed results will be handled.
Calibration
The relationship between forecast probabilities and observed outcomes over many predictions. A well-calibrated forecaster should be correct roughly 70 percent of the time when repeatedly assigning a 70 percent probability.
