We wouldn't blame Teradata Corporation (NYSE:TDC) shareholders if they were a little worried about the fact that Hillary Ashton, the Chief Product Officer recently netted about US$1.6m selling shares at an average price of US$29.10. Probably the most concerning element of the whole transaction is that the disposal amounted to 100% of their entire holding.

Teradata Insider Transactions Over The Last Year

Notably, that recent sale by Hillary Ashton is the biggest insider sale of Teradata shares that we've seen in the last year. So it's clear an insider wanted to take some cash off the table, even below the current price of US$29.79. We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. This single sale was 100% of Hillary Ashton's stake.

In the last year Teradata insiders didn't buy any company stock. You can see the insider transactions (by companies and individuals) over the last year depicted in the chart below.

Insider Ownership Of Teradata

Many investors like to check how much of a company is owned by insiders. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. Teradata insiders own about US$23m worth of shares. That equates to 0.8% of the company. This level of insider ownership is good but just short of being particularly stand-out. It certainly does suggest a reasonable degree of alignment.
