Some interesting insider buying activity at AIA over the last month, as originally covered by Robert Halili in the SCMP:

• 27th February, 2017: Independent non-executive director Lawrence Lau purchased 100,000 shares on the exchange at an average price of HKD 50.10 per share (total consideration is about ~US$645k). Following the purchase, his total shareholding in the company increased from 40,000 to 140,000 shares.
• 15th February, 2017: CEO Mark Tucker also made a (smaller) purchase of 205 shares on the exchange at an average price of HKD 47.51 per share. Following the purchase, his stake in the company increased marginally to 25.513m shares (0.21% of the company’s total shares outstanding). 

Separately, Capital Group also increased their stake in AIA via the purchase of a net 1.25m shares on the exchange at an average price range of HKD 47.55 to 48.69 per share. Those purchases were made between the 15th and 17th of February. As a result, Capital Group now holds an ~8.01% stake in AIA (up from 7.99% before the event).
