e-MyStocks is an earnings tracker built for retail traders who want more signal than a calendar. — WHAT YOU GET — • Earnings calendar across thousands of US stocks (NYSE + NASDAQ + AMEX), sorted by days until report, with BMO / AMC timing. • Multi-quarter growth trends. Revenue and EPS year-over-year for the last 4 quarters, with acceleration/deceleration arrows that tell you at a glance whether the business is speeding up or slowing down. • Consensus & beat rates. Analyst consensus vs. historical actuals. See a company's beat streak and estimate-revision direction before the report lands. • Live momentum signal. BUY / SELL / HOLD tags for S&P 500 names, refreshed every 15 minutes during US market hours. Includes a "will flip on next bar" indicator so you can see setups about to trigger. • Post-earnings drift matrix. What actually happened to a stock 1, 3, 5, and 20 days after past reports — so you can see whether the market tends to fade or extend a beat. • Options implied move. The straddle-implied 1-day move priced in before each report, side-by-side with the actual historical reaction. • Playbook cards. For candidate stocks, a short plain-English breakdown of the setup: why the signal fired, where the risk is, what would invalidate it. • Insights hub. Market Movers, PEAD Drift Matrix, Earnings Duel head-to-head, Analyst Upside leaderboard, Earnings Scoreboard, Tonight's Hot List, 52-Week Range Position, Smart Screens, and Implied vs Realized Move — all in one place. • Personal watchlist with local earnings reminders, always-on daily change pill (live during market hours, "Fri close" qualifier outside of them), sector heatmap, and full analyst outlook on every detail page. — HOW IT WORKS — Fundamentals come from SEC EDGAR filings and Yahoo Finance. Prices, analyst ratings, and price targets come from Financial Modeling Prep. Everything is refreshed before market open, topped up every 15 minutes during hours, and republished 90 minutes after close so the day's actual closing prices land on your watchlist. — WHAT THIS IS NOT — e-MyStocks is an informational and educational tool. It is not investment advice, a brokerage, or a recommendation service. All decisions are yours. — PRIVACY — Watchlist and preferences live on your device — we never upload them. Sign-in (optional) only enables the live momentum signal stream. You can delete your account at any time from the profile menu. Full privacy policy: https://e-mystocks.web.app/privacy
