What is "Trading by Type of Investors"?
A statistic compiled by the Tokyo and Nagoya stock exchanges from reports by trading participants (securities firms) with capital of ¥3 billion or more, adding up trading value by type of investor. The previous week's figures are published at 15:30 on the fourth business day of each week (usually Thursday).
Net = purchases − sales (positive: net buying, negative: net selling)
- Foreign investors
- The main players in Japanese stocks, accounting for roughly 60–70% of trading value. Prices tend to rise while they keep buying, and they are the group most closely tied to the Nikkei 225.
- Individuals
- Cash and margin trading combined. They clearly trade against the trend: buying when prices fall and selling when they rise.
- Investment trusts
- Trading by public investment funds. Often net buyers, helped by inflows from new NISA accumulation plans.
- Business corporations
- Trading by ordinary companies, mostly share buybacks, so it reflects how much companies return to shareholders.
- Trust banks
- Manage money for pension funds and others. They tend to sell after big rises to rebalance, and buy after falls.
- Proprietary (securities firms)
- Securities firms trading on their own account. Affected by arbitrage with futures, so the weekly figures swing widely.
