When there are too many numbers but you don't know where to start
JubJub is an app that collects the financials, earnings, and estimates of each individual stock and compresses them into a 'JubJub Score' ranging from 0 to 100. It is updated every trading day, and the reasons behind the score are also noted.
■ New features in this version
· The screen layout has been reorganized into 5 categories: Home, Discover, PRO, My Stocks, and My.
· You can view US stocks on the same screen as domestic stocks.
· A screen has been added to select and view Electronic Disclosures (DART) by type.
· 'Consensus Revision' has been launched to aggregate 4-week changes in securities market estimates.
· You can add up to 10 domestic and 10 US stocks to your watchlist.
· Screen transitions and pop-up behaviors have been generally refined.
■ You can view without signing up
We don't hide stock names or scores. Login is only required for features that require an account, such as watchlists or notifications.
**When there are too many numbers but you don't know where to start** ■ What You Can See
· Bargain Score — We collect indicators from approximately 2,700 KOSPI and KOSDAQ stocks, narrow them down to 500, and display the top 100 daily on cards.
· Six-Structure Decomposition — Consensus, Quarterly Acceleration, Value Gap, Surprise Earnings, Financial Soundness, and Price Appeal. Explore which axis a stock earned points.
· Basis for Judgment — We don't just throw numbers at you. We attach a one-line summary and tags explaining which financial facts contributed to the score.
· Discover — Drag to narrow the score range and search directly by adding financial and consensus conditions.
· Consensus Revision — Compare this week's estimates with those from four weeks ago to count upward and downward revisions. We look at the direction the consensus is moving, not just what the current consensus is.
· Bargain Index — Start with the market before picking stocks. Record KOSPI overheating and investor sentiment daily on a scale of 0 to 100.
· Electronic Disclosures — View DART disclosures categorized into 9 types and jump directly to the original text.
· US Stocks — Update daily top 50 stocks based on financial and growth indicators.
■ Records Daily
We have been saving stock scores for every trading day since March 30, 2026. Instead of relying on just today's value, you can compare yesterday's and four months' worth of data using the same criteria.
