Evidence
Why these signals fired — only backtest-proven edge, told honestly
Not this one stock, but every strong-buy pick we actually published (Korea market). When this stock flashes the signal, it is treated by the same rule.(as of 2026-08-03)
Beat the market on 62.1% of picks (each pick vs its own day’s market average).
Entry is the latest close at publish time; next-day is the following close. “Market” is the equal-weighted average of every stock in the same market that day; delisted names are excluded from both. Fees, taxes and slippage are not included. An observed record over a short window, not a pre-registered backtest. Not investment advice.
No statistical flag
