Sell in May

PROFESSIONAL MARKET ANALYSIS. COMPLETELY PRIVATE. Sell in May brings institutional-quality market intelligence to your iPhone and Mac. Combining historical pattern recognition with optional on-device LSTM deep learning, it reveals what history suggests about any stock's future — under current market conditions — and can now keep watch on your Watchlist while you're away. WHY SELL IN MAY IS DIFFERENT Unlike simple charting apps, Sell in May is regime-aware: it classifies market conditions (volatility, trend, sentiment, macro regime) and only shows you patterns from similar historical periods, because markets don't behave the same in bull runs and bear markets. DUAL-ANALYSIS ENGINE • Pattern Matching: Scans 10+ years of data to find similar price patterns from comparable market regimes • Optional LSTM AI Forecasting: Probabilistic predictions for 5, 10, and 20-day horizons, with a clear "unavailable" indicator on the rare occasion the on-device model can't load • Two complementary perspectives reduce prediction bias REGIME-AWARE INTELLIGENCE Automatically detects volatility (Low/Medium/High), trend (Trending/Mean-Reverting/Neutral), risk sentiment (Risk-On/Risk-Off/Neutral), and macro regime (Recession, Slowdown, Recovery, Expansion, Stagflation). Historical patterns are filtered to match YOUR current regime. WATCHLIST & DAILY BRIEF (Optional) • Track the symbols you care about with an opt-in Morning Brief notification • Overnight pattern scanning surfaces real high-confidence matches found across your Watchlist while you slept • Optional mid-day pattern-alert pass for a second check during market hours AI CHAT • Ask questions about any analysis in plain language, powered by an on-device LLM • Conversations persist as you navigate instead of resetting on every tap • Dynamic suggestion chips surface the forecast direction and top historical pattern for the symbol you're viewing FUNDAMENTALS & DCF CALCULATOR • Per-ticker discounted cash flow calculator with live free cash flow / net debt auto-populated from market data • Peer correlation heatmap and risk & performance metrics against a configurable benchmark MACRO-ECONOMIC CONTEXT (Optional) With a FRED API key, integrates Federal Reserve data: interest rates, yield curve, credit spreads, CPI year-over-year, unemployment, sentiment, and recession probability. Patterns from similar economic conditions receive a similarity boost. PROBABILISTIC FORECASTING Never just a single number — always a range: multi-horizon predictions with confidence intervals, return percentiles (10th/25th/median/75th/90th), downside risk probabilities, and expected volatility. 100% PRIVACY-FIRST Complete on-device processing — your data never leaves your phone or Mac.
