Last week, SinoMab BioScience Limited's (HKG:3681) stock jumped 11%, but insiders who sold CN¥4.3m worth of stock in over the past year are likely to be in a better position. Selling at an average price of CN¥1.80, which is higher than the current price, may have been the wisest decision for these insiders as their investment would have been worth less now than when they sold.

While insider transactions are not the most important thing when it comes to long-term investing, we would consider it foolish to ignore insider transactions altogether.

SinoMab BioScience Insider Transactions Over The Last Year

The President of China & Executive Director, Shanchun Wang, made the biggest insider sale in the last 12 months. That single transaction was for HK$4.3m worth of shares at a price of HK$1.80 each. While insider selling is a negative, to us, it is more negative if the shares are sold at a lower price. The good news is that this large sale was at well above current price of HK$1.34. So it is hard to draw any strong conclusion from it. Shanchun Wang was the only individual insider to sell over the last year.

It certainly does suggest a reasonable degree of alignment.
