Sino Biopharmaceutical Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the Founder & Senior Executive Vice Chairman, Ping Tse, for HK$51m worth of shares, at about HK$3.72 per share. That means that even when the share price was below the current price of HK$6.71, an insider wanted to cash in some shares. As a general rule we consider it to be discouraging when insiders are selling below the current price, because it suggests they were happy with a lower valuation. However, while insider selling is sometimes discouraging, it's only a weak signal. It is worth noting that this sale was only 0.8% of Ping Tse's holding. The only individual insider seller over the last year was Ping Tse.
