SIGNUM HQ is a US stock earnings app. Before a company reports, see the move that option prices imply. After it reports, see what the stock actually did. Earnings calendar, weekly scorecard, premarket and after hours prices, a watchlist with a home screen widget, and plain-language market briefings, all in one app for US stocks and the Nasdaq.

EXPECTED MOVE VS WHAT ACTUALLY HAPPENED
Option prices imply a range for each earnings report: the expected move. Once the company reports, SIGNUM HQ shows the real one-session reaction next to it, so you can see which stocks stayed inside the range and which went past it.

WEEKLY EARNINGS SCORECARD
Each week the app tallies the companies that have reported against their expected moves. For example, in the week of Nov 2, 2026, 18 of 27 stocks moved within the expected range and 9 went beyond it. The expected move reflects market pricing, not a forecast, and past results do not predict future ones.

EARNINGS CALENDAR
Who reports before the open and after the close, how many days to go, and the EPS estimate. The expected move is shown for stocks where data is available.

SELL-OFF BRIEFING
When the market drops sharply, the home screen shows a briefing: how far the indexes and volatility moved, a short explanation of why, and which earnings reports were behind big moves.

WATCHLIST AND HOME SCREEN WIDGET
Tap the heart on any stock to follow it. Each stock's price, options levels and earnings date sit in one line. Add the Android home screen widget to check your watchlist without opening the app.

PREMARKET AND AFTER HOURS
See what moved outside regular hours and why, plus a morning brief before the open and a closing report after the bell, with push alerts when they are published.

SECTORS AND THE MARKET
A sector heatmap and AI sector reports for all 10 sectors show which parts of the US stock market led or lagged today, explained in plain language.

OPTIONS DATA, WHEN YOU WANT MORE
Options are the basis for the expected move, and the app also covers options flow, put/call ratio, max pain, gamma exposure (GEX) and dark pool volume for those who want to go deeper.

TERMS IN PLAIN ENGLISH
• Expected move (implied move): the size of the move that option prices expect around an earnings report. It does not say whether the stock will go up or down.
• Premarket and after hours: the trading sessions before the open and after the close.
• Max pain: the strike price at which option buyers as a group lose the most at expiration. It does not always predict where price ends up.
• Gamma exposure (GEX): shows whether option dealers' positioning tends to amplify or dampen price moves.
• Dark pool: off-exchange trading where large orders are matched. Dark pool volume is its share of total volume.
