Based on the daily short-selling aggregation for 2 November, short selling accounted for approximately 36.9% of trading value. The amounts by category and the difference between short interest and trading value are explained.
Based on the daily “Short-Selling Aggregation” published by Japan Exchange Group (JPX), the data covers trading on 2 November 2026. Short selling is classified into 2 categories, with and without price restrictions, and the total trading value in the original table is 83,521,02 million yen. The combined value of the 2 short-selling categories is ¥3,078,262 million. Dividing this by total trading value gives approximately 36.9%.
Adding the percentages shown in the same table gives 36.8%, a difference of 0.1 percentage points due to rounding. The daily aggregation shows only the percentage of trading value for that day and does not indicate changes in outstanding short positions. Short interest is disclosed separately, but because only positions at or above 0.5% are covered, the overall trend in outstanding short positions cannot be fully captured.
The article points out that the criteria for daily trading-value percentages differ from those for disclosing short interest, and cautions against attributing reasons to individual stocks or reaching conclusions about market trends based on a single source. It also explains that the name of the source, the period covered and the unit should be specified when conducting research.
