The Last 12 Months Of Insider Transactions At Generation Bio

Over the last year, we can see that the biggest insider purchase was by Independent Director Anthony Quinn for US$203k worth of shares, at about US$0.97 per share. So it's clear an insider wanted to buy, even at a higher price than the current share price (being US$0.42). While their view may have changed since the purchase was made, this does at least suggest they have had confidence in the company's future. To us, it's very important to consider the price insiders pay for shares. As a general rule, we feel more positive about a stock when an insider has bought shares at above current prices, because that suggests they viewed the stock as good value, even at a higher price. Anthony Quinn was the only individual insider to buy shares in the last twelve months.

Does Generation Bio Boast High Insider Ownership?

I like to look at how many shares insiders own in a company, to help inform my view of how aligned they are with insiders. We usually like to see fairly high levels of insider ownership. Insiders own 6.1% of Generation Bio shares, worth about US$1.6m, according to our data. Whilst better than nothing, we're not overly impressed by these holdings.

So What Does This Data Suggest About Generation Bio Insiders?

It doesn't really mean much that no insider has traded Generation Bio shares in the last quarter. On a brighter note, the transactions over the last year are encouraging. We'd like to see bigger individual holdings. However, we don't see anything to make us think Generation Bio insiders are doubting the company. So these insider transactions can help us build a thesis about the stock, but it's also worthwhile knowing the risks facing this company.
