Discover Alternative Stock Alerts

A stock alert is a real-time notification that flags significant movement in a specific stock — either in price or in an underlying alternative-data signal like social media mentions, web traffic, app downloads, hiring trends or insider trades. AltIndex sends stock alerts when any of more than 10,000 signals breaks out on a public company.

Our stock alerts are generated through analysis of alternative data from thousands of publicly traded companies. We examine factors beyond traditional price metrics — social media presence, web traffic, mobile app downloads, hiring trends, employee sentiment, insider activity and more — and surface stocks where any of those signals is breaking out of its normal range.

A traditional price alert fires when a stock crosses a threshold you set in advance. AltIndex stock alerts go further: they automatically flag stocks where the underlying alternative-data signals (Reddit mentions, web traffic, hiring activity, insider trades) are breaking out. Price alerts react to price moves. Alternative-data alerts surface shifts in the underlying signals that sit alongside price — useful context for understanding why a stock might be moving, or might be about to.

Stock alerts are signals, not guarantees. The full historical track record of every AI Stock Pick we have ever sent is published at altindex.com/results — including the wins and the losses. Historically, AltIndex AI Stock Picks (the high-conviction subset of alerts) have delivered roughly a 70% win rate. Past performance is not indicative of future results.

AltIndex is the only stock alert app powered by 10,000+ alternative-data signals — Reddit, web traffic, app downloads, hiring trends, insider trades and more. Most other stock alert apps (Robinhood, Yahoo Finance, etc.) only offer manual price alerts. Download AltIndex on iOS or Android.

AltIndex stock alerts trigger when any tracked alternative-data signal breaks abnormally above or below its baseline. Signal categories include: Reddit and social media mentions, web traffic, mobile app downloads, hiring activity, insider transactions, Congressional trades, sentiment scores, employer ratings, business outlook and the proprietary AltIndex AI Score.

Our system monitors thousands of companies every day, ensuring that stock alerts are generated and sent as soon as significant movements or events are detected. The frequency of alerts varies based on market conditions and the activity of individual stocks.

Subscribers can expect a diverse array of insights including stock sentiment, app downloads, job postings, web traffic, Reddit mentions, social media followers, employee ratings and AI Score. Each alert tells you which signal moved, by how much, and links to the full company dashboard.

Stock alerts are a tool for staying informed and making data-driven decisions. By receiving real-time notifications on a wide range of factors impacting stock performance, you can react promptly to market changes, adjust your strategy accordingly, and avoid missing catalysts buried in noisy news cycles.
