Trade Signal app
Market Cap Rankings & Alerts
Free · Designed for iPad. Not verified for macOS.
TradeSignal tells you when market-cap rankings change.
Get an alert the day a market's #1 changes, a company enters or leaves the Top 10, or an index addition is announced. Everyone gets the same facts in the same words, and we never recommend buying or selling.
WHAT WE ALERT YOU ABOUT
- A new #1 by market cap
- Entries and exits in the Top 10, 20, 30 and 50
- The #1–#2 gap narrowing past 10%, 5% and 1%
- A new #1 within a sector
- Index additions and removals announced for the S&P 500, Nasdaq 100, Dow 30, KOSPI 200 and KOSDAQ 150
SEVEN MARKETS
US, KOSPI, KOSDAQ, Japan, Hong Kong, UK and Germany. Each market is ranked separately by market cap at each trading day's close.
YOU CHOOSE WHAT YOU GET
Pick markets, sectors, rank range (Top 10 to 50) and indexes, then choose Instant, Daily or Weekly delivery. You can also set quiet hours for push notifications.
EVERY ALERT SHOWS ITS BASIS
Who passed whom, that day's closing moves, rank and market-cap gap trends, company basics, and related news headlines with their sources, all on one screen.
RANKS TAB
See market-cap rankings for each market every day. Narrow them by index or sector, and tap a company for its profile, rank and closing-price history, recent events and related news. No sign-in needed to view rankings.
DATA SOURCES
Korea: official market cap from the Public Data Portal (Financial Services Commission). Other markets: market cap at close from Yahoo Finance. Index changes come from announcements by index providers and exchanges.
