Margin Call: AI Stock & Crypto

Margin Call is an AI stock market app for stock picks, live stock prices, charts and crypto prices. Track stocks across 7 markets — US (NASDAQ, S&P 500), Korea, Japan, Germany, France, Spain and Brazil — plus cryptocurrencies like Bitcoin and Ethereum in one stock tracker, with AI-powered analysis of companies, sectors and positions. It does not execute trades; every output is reference information to support your own decisions.

■ Key features

• AI company analysis
AI summarizes fundamentals, technical indicators and market context for each stock. Market cap, P/E ratio, dividend yield and 52-week highs and lows are read alongside RSI and moving averages, so strengths, risks and points to watch are laid out in plain language. You get the current state of a stock without reading a full report.

• Watchlist & portfolio tracker
Track US stocks, Korean stocks, Japanese stocks and European and Brazilian names in a single watchlist with live quotes. Enter your average cost and share count to see unrealized P&L, return percentage and position weight calculated automatically. Switch between USD and KRW, and see pre-market and after-hours moves for US listings.

• Exit strategy tool
Analyze the structure of your position against your entry, target and stop-loss levels. Distance to target, gap to your stop and whether the trend is intact are summarized as observational labels, so you can read where a position stands in numbers rather than emotion.

• AI stock picks & stock screener
Quantitative signals combined with AI valuation surface stock and crypto candidates worth a closer look. Volume spikes, trend reversals and valuation gaps are scanned, and each candidate comes with the reasoning behind it. You can also review how past picks performed on a public track record page.

• Sector analysis & diversification
See how the 11 GICS sectors are moving along with their leading names, and check how concentrated your holdings are in any one sector using an HHI score. Review the balance of your portfolio from a diversification perspective.

• Crypto scanning & early signals
Live prices and quantitative scans for top coins by market cap, including Bitcoin, Ethereum and Solana. Volume- and trend-based early signals help you follow altcoin movement.

• Home screen widget & alerts
Check current prices and daily change for your watchlist from a home screen widget without opening the app. Market alerts help you catch intraday moves.
