Find the stocks worth watching before the crowd does.
StockHark spots stocks gaining real traction across financial communities and market news, then runs ML models to predict where they are heading. You get a ranked list of the most relevant plays, updated every hour.
From raw chatter to a price direction signal.
Every stock runs through the same five steps, refreshed once an hour, ending in an ML prediction.
Collect
Thousands of posts pulled from 25+ financial subreddits, plus breaking headlines from Finnhub news.
Score
FinBERT, a transformer trained on financial text, reads each one and rates it bullish, bearish, or neutral.
Weight
Recent and high-volume mentions count for more. A single viral post cannot skew the picture.
Surface
Tickers rank by momentum and sentiment shift. Stocks that cross signal thresholds are flagged for the next step.
Predict
Four HistGradientBoosting models score each triggered stock on 1-day and 5-day direction and magnitude, using 23 features including sentiment, RSI, MACD, and VIX.
Cut the noise. Focus on what actually matters.
Most stocks getting talked about online are just noise. StockHark filters through thousands of posts and breaking news every hour to surface the ones genuinely gaining momentum, whether that is an earnings surprise, a sentiment spike, or a price move the crowd has not priced in yet.
When a stock clears our signal thresholds, it enters the prediction queue. Four ML models then score its likely 1-day and 5-day direction using 23 features: technical indicators, sentiment trends, analyst positioning, and macro context. The result is a short, ranked list of stocks actually worth your attention right now.
We built this because screeners show you everything and analysts show you what they want you to see. StockHark shows you what the market is actually moving on, with a prediction on where it is going.
Built around one screen you will actually watch.
The dashboard, your watchlist, history charts, alerts that respect your inbox, and ML predictions that tell you where the signal is pointing.
An instant read on every trending stock.
Each card gives you mention volume and an AI sentiment score at a glance, so you can spot what the crowd is watching before it goes mainstream.
- Live mention tracking across Reddit's top financial communities.
- AI sentiment scores with bullish, bearish, or neutral classification.
- 2h / 6h / 24h / 48h windows to match your trading horizon.

A scanner tuned to your tickers.
Mark the stocks you care about and StockHark watches them for you. As long as one stays in the top 100 most discussed, you stay in the loop. When it goes quiet, alerts pause on their own.
- Instant search to add any ticker in one click.
- Top-100 presence alerts the moment a favourite enters the conversation.
- Auto-pause when a stock drops out of the top 100.
- Pinned access every time you open the dashboard.
These alerts are separate from trending alerts. You'll get an email when your picks make the Top 30, regardless of sensitivity.
Thirty days of sentiment, at a glance.
See how the crowd's mood around any stock has shifted over the past month. Knowing what they thought yesterday helps you read what they might do next.
- 30-day history of mention volume and sentiment in one view.
- Sentiment momentum shows exactly when opinion flips.
- Volume spikes surface unusual activity immediately.
- Side-by-side comparison across multiple stocks.
Two alert channels, one inbox.
StockHark watches the market for you and emails the moment something worth knowing happens. Per-stock cooldowns keep it useful instead of noisy.
- Trending alerts when a top-30 stock surges in mentions or sentiment.
- Watchlist alerts when a stock you track enters the top 100.
- Sensitivity control from quiet, strong-signal-only to early-and-often.
- 72-hour cooldown per stock to prevent repeat noise.
Direction and magnitude, backed by 23 features.
Gradient-boosting models trained on price action, sentiment trends, VIX, and earnings proximity score triggered stocks each cycle. You see the top calls ranked by confidence, not noise.
- 1-day and 5-day direction calls rated up, down, or neutral with a confidence percentage.
- Magnitude estimates show how large a move the model expects.
- Three signal triggers: earnings proximity, sentiment spike, and price move above threshold.
- Continuous retraining as new labeled outcomes arrive, so the model stays current.
A side project that got out of hand.
We are a group of developers from Austria who got hooked on making sense of Reddit's stock chatter. What started as a side project, fueled by curiosity and late-night coding sessions, turned into StockHark.
No corporate backing, no fancy office, just genuine interest in building something useful. We believe good tools should not be locked behind institutional walls, so we are putting everything we have into making sentiment analysis accessible to everyone.
Built with dedication, powered by coffee, and driven by the simple goal of making something we would want to use ourselves.
Track what the market is actually saying.
Live sentiment, watchlist alerts, history charts, and ML price direction predictions, all in one place.
