Short selling in Japan

Positions open on August 6, 2026, disclosed to JPX. See the official publication.

JPX also publishes the positions of securities firms, far below the threshold other markets use. Its companies compare, its holders do not, so this market is kept out of the ranking of the busiest short sellers.

Sum of the short positions open on each company, as a percentage of capital.
