The 8 stock trading signals we publish
Each signal has its own daily leaderboard. Click into any signal to see the top stocks ranked by that input today.
How AltIndex generates each stock trading signal
Every signal we publish follows the same three-step pipeline:
- Collect. We ingest 10,000+ alternative-data points per stock per day — Reddit posts, Employee reviews, Job postings, web-traffic estimates, app-store rankings, social-media follower counts, sentiment scores — alongside traditional financial data (price, volume, fundamentals).
- Score. Each signal is normalized into a percentile rank against its own historical range and the broader universe. Outsized moves (a stock’s Reddit mentions jumping 3× weekly average, web traffic rising 30% MoM, hiring doubling YoY) trigger inflection flags.
- Publish. When multiple signals inflect in the same direction, the stock earns a buy or sell signal that lands on the AI Stock Picks feed and is logged on the Track Record page. Members get push and email alerts on stocks they’re watching.
Worked example: on Jan 17, Duolingo (DUOL) received a buy signal because three alternative-data inputs inflected together — social-media followers, mobile app downloads, and employee business outlook were all accelerating month-over-month, alongside healthy financials. That combination is the kind of forward-looking pattern traditional signals don’t see until price has already moved.

Stock trading signals are data-driven buy or sell alerts that flag when a stock is likely to move based on quantifiable inputs. Traditional signals come from price action, technical indicators, and earnings revisions. AltIndex’s signals add an alternative-data layer: Reddit mentions, web traffic, hiring activity, employee business outlook, app downloads, social-media followers, and an AI Score that combines them — signals that often move before price reacts.
AltIndex ingests 10,000+ alternative-data points per stock per day — consumer behaviour, hiring trends, social attention, sentiment, financials — and runs them through a daily scoring model. Stocks whose signals inflect (e.g. a sharp rise in Reddit mentions paired with rising web traffic and positive employee outlook) trigger a buy signal; the reverse triggers a sell. The full AI Score and underlying signal breakdown is published daily for every monitored stock.
AI stock trading means using machine-learning models to decide what to trade and when, instead of relying on charts and gut feel alone. AltIndex applies AI to 10,000+ alternative-data and financial signals per stock and turns them into daily AI-scored buy and sell signals. It’s built to inform your trading decisions with data, not to place trades for you — you stay in control of execution and risk.
Every AltIndex stock pick is published transparently with its entry price and tracked through time. The full historical record — win rate, average return, every signal-driven pick we’ve made — is available on the Track Record page. Past performance isn’t a guarantee, but transparency keeps us honest.
Eight signal categories: AI Score (composite 0–100 read), Reddit mentions, Sentiment, web traffic to company sites, hiring activity (open job posts and headcount), employee business outlook (Glassdoor), app downloads for consumer apps, and social media followers (Instagram, X, TikTok). Each signal has its own leaderboard at /toplist.
TradingView, TipRanks and Benzinga are excellent for price action, analyst ratings, and news. They lean almost entirely on market-derived data. AltIndex layers in alternative data — behavioural signals from Reddit, hiring boards, app stores, Glassdoor, web-analytics providers — that the major platforms don’t track. Use both: market data confirms what’s already happened; alt data hints at what’s about to.
Daily. The full universe of monitored stocks is rescored every morning using the most recent available data. Members can receive near-real-time alerts when a stock in their portfolio inflects on a key signal.
Yes. The same alternative-data framework powers the Crypto Fear & Greed Index and per-coin scores. Crypto signals lean more heavily on Reddit, Stocktwits, news mentions and Wikipedia pageviews (attention-driven market), while stock signals add hiring and Glassdoor.
