Don't Ignore The Insider Selling In Ambarella

Listen to the news

We'd be surprised if Ambarella, Inc. (NASDAQ:AMBA) shareholders haven't noticed that the Co-Founder, Feng-Ming Wang, recently sold US$395k worth of stock at US$64.83 per share. However, the silver lining is that the sale only reduced their total holding by 0.8%, so we're hesitant to read anything much into it, on its own.

Ambarella Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Senior VP of Systems & GM of Asia Design Centers, Chi-Hong Ju, sold US$909k worth of shares at a price of US$81.29 per share. While we don't usually like to see insider selling, it's more concerning if the sales take place at a lower price. It's of some comfort that this sale was conducted at a price well above the current share price, which is US$66.15. So it may not shed much light on insider confidence at current levels.

In the last year Ambarella insiders didn't buy any company stock. The chart below shows insider transactions (by companies and individuals) over the last year. If you click on the chart, you can see all the individual transactions, including the share price, individual, and the date!

Does Ambarella Boast High Insider Ownership?

For a common shareholder, it is worth checking how many shares are held by company insiders. A high insider ownership often makes company leadership more mindful of shareholder interests. Ambarella insiders own about US$133m worth of shares (which is 4.6% of the company). Most shareholders would be happy to see this sort of insider ownership, since it suggests that management incentives are well aligned with other shareholders.
