So we get scored.

Last updated 2026-10-15 07:32 PDT

We show the reasons in numbers, then check whether every stock in the digest beat its index 5, 20 and 60 trading days later. Hits and misses, published as they come.

Not live tape. One issue a day — the reasons, then the score.

  • Reasons and warning signs — Why it could rise, what would prove us wrong, and whether we own it.
  • Every pick scored — Every stock we feature is compared with its index 5, 20 and 60 trading days later, in public. The rules are set in advance.
  • Korea and the US, side by side — Two markets, one set of rules, one scorecard. Free.

How we score: the weight of evidence

Each Korean stock in the digest gets four yes/no checks. The number of yeses is the weight of its evidence.

Results are recorded from the issue-date close to the close 5, 20 and 60 trading days later. Whether this method means anything was tested on a pre-registered sample of 60 (at five trading days), and the result is published on the scorecard as it came out. See the full public scorecard →
