Vivani Medical Insider Transactions Over The Last Year

Notably, that recent purchase by Gregg Williams is the biggest insider purchase of Vivani Medical shares that we've seen in the last year. That implies that an insider found the current price of US$1.69 per share to be enticing. 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. In this case we're pleased to report that the insider purchases were made at close to current prices.

While Vivani Medical insiders bought shares during the last year, they didn't sell. The average buy price was around US$1.33. To my mind it is good that insiders have invested their own money in the company. However, we do note that they were buying at significantly lower prices than today's share price. You can see the insider transactions (by companies and individuals) over the last year depicted in the chart below.
