Track record: for every new report (a position crossing 0.5%) published since 2026-06-01, the stock's return from the next trading day's open to the close 20 trading days later. "vs all reports" compares it with the average for all stocks reported on the same days (all new reports: n=6,499, average +1.43%, share that fell 44.2%). Delisted stocks drop out (survivorship bias). This is a record of the past, not a sign that following any institution produces a result.

FAQ
What is short interest in Japanese stocks?
Kaburadar uses the term for the sum of disclosed short positions of 0.5% or more of shares outstanding that JPX publishes for each stock. Positions below 0.5% are not disclosed, so the actual total short position is larger.
How often is Japan short interest data published?
JPX publishes the short-selling position reports every business day, about two business days after the calculation date. This page is rebuilt every weekday evening (Japan time).
Does a large short position mean the stock price goes down?
No. Reported positions include hedging and arbitrage by brokers and market makers. The institution table shows the past record after new reports; on average it is close to the average for all reported stocks.
