Quantactic helps you understand what changed in the market, why a move stands out, what may happen next, and how its forecasts have actually performed. FOLLOW WHAT CHANGED Track stocks and ETFs you care about and quickly see unusual price movement, volume activity, trend changes, and broader market context. UNDERSTAND THE MOVE Quantactic compares current activity with recent market behavior to show whether a move looks normal, unusual, sector-supported, or stronger than the broader market. EXPLORE PROBABILISTIC OUTLOOKS Run 7-, 30-, and 90-day scenario forecasts built from historical market behavior. Explore expected ranges, sampled upside and downside outcomes, confidence, and the factors influencing the outlook. SEE THE MODEL’S TRACK RECORD Quantactic keeps completed forecasts so you can compare previous outlooks with what actually happened. Review directional accuracy, forecast error, range coverage, and historical outcomes. GO DEEPER WITH SIGNALS Inspect explainable market signals, factor weights, trend conditions, risk context, and conditions that could weaken or invalidate a setup. COMPARE IN CONTEXT Compare multiple stocks and ETFs from a timestamp-aligned starting point instead of relying on disconnected percentage moves. PRIVATE AI-POWERED RESEARCH Use supported Apple Intelligence features for private, on-device explanations and research assistance. BUILT FOR RESEARCH — NOT TRADING Quantactic does not place trades, connect to brokerage accounts, accept deposits, or manage investments.
