Your Korean stocks, watched every night.
Korean companies drop most of their worst news after the market closes — in Korean. We read every filing after each market day. If a stock you hold files something that matters — a dilution, a capital wipeout, an embezzlement charge — it's in your inbox before the next open, with the original document and the company's full pattern.

The guard
Watchlist alerts: when one of your stocks files a dilution or fatal event, the email goes out the same evening (KST) — before the next Korean open — with the filing and its pattern context. See a sample alert →

Hold $5,000 of a Korean small cap carrying our highest risk rating and history says 42.1% of such companies were later delisted for cause — close to a total loss when it lands. Membership is $9 a month at launch — pocket change standing guard against a four-figure tail risk. (Measured on 2,426 listed companies, outcomes tracked to 2026 — method.)
