Anyone interested in Ambarella, Inc. (NASDAQ:AMBA) should probably be aware that the Senior VP of Systems & GM of Asia Design Centers, Chi-Hong Ju, recently divested US$239k worth of shares in the company, at an average price of US$57.11 each. However, the silver lining is that the sale only reduced their total holding by 2.3%, so we're hesitant to read anything much into it, on its own.

Ambarella Insider Transactions Over The Last Year

Notably, that recent sale by Senior VP of Systems & GM of Asia Design Centers Chi-Hong Ju was not the only time they sold Ambarella shares this year. They previously made an even bigger sale of -US$348k worth of shares at a price of US$81.81 per share. We generally don't like to see insider selling, but the lower the sale price, the more it concerns us. The good news is that this large sale was at well above current price of US$57.43. So it may not shed much light on insider confidence at current levels.
