A-Share T+1 Rules, Short Selling, and Intraday Trading Claims

Summary

This article argues that China’s A-share T+1 settlement rule can constrain retail traders who buy shares during a session, while some institutions may approximate intraday trading through previously held inventory or short selling. It describes two proposed mechanisms: selling borrowed shares after a price rise and buying them back later, or selling eligible older holdings and replacing them at a lower price. It attributes retail disadvantages to funding requirements and limited access to securities lending.

The article gives illustrative price moves and a claim about institutional control of securities-lending capacity, but it offers no source data, transaction records, or empirical analysis to substantiate its portrayal of deliberate price manipulation or reliable profits. Its claims should therefore be read as an opinionated explanation, not as established market evidence or a dependable strategy description. Actual access, rules, borrow availability, costs, and execution outcomes can vary, and the article does not quantify those constraints in a tested framework.

Key ideas

• The article contrasts retail investors’ T+1 selling restriction with institutions’ ability to trade using older inventory.
• It describes a short-selling scenario in which borrowed shares are sold and later repurchased.
• It argues that capital and securities-lending access limit retail investors’ ability to replicate these approaches.
• The article provides no empirical verification for its claims about manipulation, profitability, or lending-market concentration.
