Those following along with Atara Biotherapeutics, Inc. (NASDAQ:ATRA) will no doubt be intrigued by the recent purchase of shares by Brian Cherry, Independent Director of the company, who spent a stonking US$1m on stock at an average price of US$9.60. That purchase boosted their holding by 272%, which makes us wonder if the move was inspired by quietly confident deeply-felt optimism.
Notably, that recent purchase by Brian Cherry is the biggest insider purchase of Atara Biotherapeutics shares that we've seen in the last year. That means that an insider was happy to buy shares at around the current price of US$9.76. That means they have been optimistic about the company in the past, though they may have changed their mind. We do always like to see insider buying, but it is worth noting if those purchases were made at well below today's share price, as the discount to value may have narrowed with the rising price. The good news for Atara Biotherapeutics share holders is that an insider was buying at near the current price. Brian Cherry was the only individual insider to buy shares in the last twelve months.

It's certainly positive to see the recent insider purchase. And the longer term insider transactions also give us confidence. But on the other hand, the company made a loss during the last year, which makes us a little cautious. On this analysis the only slight negative we see is the fairly low (overall) insider ownership; their transactions suggest that they are quite positive on Atara Biotherapeutics stock. While it's good to be aware of what's going on with the insider's ownership and transactions, we make sure to also consider what risks are facing a stock before making any investment decision.
