How is AltIndex different from just checking Reddit or Twitter myself?

AltIndex aggregates sentiment across many sources (Reddit, social media, news, options flow, app downloads, insider trades) and gives you a single dashboard with baselines, alerts, and historical context. Manually checking sources misses the comparison to normal activity — AltIndex tells you when mention volume is 5x baseline, not just that people are talking.

Can sentiment analysis predict stock price movement?

Not reliably. Sentiment is a leading indicator that can identify when interest is building or fading, but stocks move on many factors (earnings, macro events, technicals). Use sentiment as one input alongside fundamentals and price action, not as a standalone signal.

Is the free tier enough to be useful?

The free newsletter tier covers basic AI picks and limited insights. For serious use — unlimited picks, real-time alerts, full alternative data access — you need a paid plan. Most retail traders start with free, then upgrade once they're actually using the data in their workflow.

AltIndex

AltIndex is purpose-built for sentiment and alternative data analysis, aggregating signals retail traders can't easily access otherwise: Reddit mention spikes, app download trends, insider trading activity, and social sentiment shifts in real time. Mobile push alerts notify you the moment a sentiment signal triggers on stocks you watch. Unlike general scanners that include sentiment as one of many inputs, AltIndex's entire product is built around catching sentiment shifts before they show up in price action. Free tier available, with premium plans for unlimited picks and predictions.

Before vs. after using this prompt

Before — without the prompt

A trader watching a stock pulls up StockTwits, scrolls Twitter, checks WallStreetBets, opens a news aggregator, glances at options flow on another site, and tries to mentally combine 15 minutes of fragmented data into a single read on whether sentiment is improving or deteriorating.

After — with the prompt

Same trader opens AltIndex on their phone, sees [TICKER]'s sentiment dashboard with Reddit mentions up 240% vs. baseline, social sentiment shifted bullish over 48 hours, app downloads up 18% month-over-month, and insider buying flagged this week — clear directional signal in under 60 seconds.
