Building a Practical Strategy Model to Exploit Executive Stock Purchases in A-Share Markets

The Shanghai Stock Exchange (SSE) implements ex-post supervision over 'short-term trading'—defined as executives buying company shares and selling them within six months, or selling and then repurchasing within six months. Similarly, the Shenzhen Stock Exchange (SZSE) imposes restrictions on short-term trading by directors, supervisors, and senior management during their term of office: 'Directors, supervisors, and senior management of listed companies shall comply with Article 47 of the Securities Law.' This implies that executive stock purchase events reflect relatively prudent investment decisions by the transacting parties, and thus exhibit relatively sustained and stable event effects. Policy Support Following the 2015 stock market crash, both the SSE and SZSE issued notices on July 8, 2015, encouraging shareholders—including concerted action parties—and directors, supervisors, and senior management of listed companies to purchase their own company’s shares. According to the SSE’s 'Notice on Matters Related to Share Purchases by Shareholders, Concerted Action Parties, Directors, Supervisors, and Senior Management of Listed Companies on the Shanghai Market': According to the SZSE’s 'Notice on Matters Related to Share Purchases by Controlling Shareholders, Actual Controllers, Directors, Supervisors, and Senior Management of Listed Companies': We have compiled statistics since 2009 on the number of listed companies involved in executive stock purchase events each quarter, as well as the proportion of those companies whose purchases exceeded RMB 3 million: Figure 1 shows that prior to Q4 2013, the number of listed companies participating in executive stock purchase events was relatively low; thereafter, it rose steadily. Following the 2015 stock market crash, under regulatory policy guidance, the number of participating companies surged by over 600 in Q3 2015 and has since remained at historically high levels. Trading Window Restrictions Both the SSE and SZSE impose 'trading window' restrictions on shareholding changes by directors, supervisors, and senior management. Per the SSE’s 'Daily Information Disclosure Work Memorandum No. 8: Operational Guidelines for Shareholding Management of Directors, Supervisors, Senior Management, and Shareholders of Listed Companies' (ex-post supervision); and per the SZSE’s 'Rules for Managing Shares Held by Directors, Supervisors, and Senior Management of Listed Companies and Their Changes': We have compiled monthly statistics on the number of executive stock purchase events: Figure 2 shows that, aside from a sharp increase in July—driven by post-crash policy encouragement in 2015—executive stock purchase events generally occur less frequently during financial reporting periods. Thus, such events can be combined with earnings-related event-driven strategies (e.g., earnings forecasts, flash reports, and full financial statements). Analysis of Executive Stock Purchase Events We have compiled quarterly statistics since 2009 on both the number of executive stock purchase events and the total purchase amount: Figure 3 shows that, especially over the past two years, both the frequency and total value of executive stock purchase events have remained at high levels. Although regulations require listed companies to announce executive shareholding changes on the stock exchange website within two trading days after the change occurs, in practice, filings may be delayed—or occasionally submitted in advance. In addition to exchange filings, listed companies may also issue separate announcements regarding executive shareholding changes—including disclosure of planned or ongoing purchases/sales. If announcements lag significantly behind the actual shareholding change date, the impact of the purchase event on investor expectations is substantially diminished.
