Listen to the news

Zenas BioPharma, Inc. (NASDAQ:ZBIO) shareholders (or potential shareholders) will be happy to see that the Independent Director, Hongbo Lu, recently bought a whopping US$5.0m worth of stock, at a price of US$19.00. That increased their holding by a full 447%, which arguably implies the sort of confidence required for a shy sweet-natured nerd to ask the most popular kid in the school to go out on a date.

Zenas BioPharma Insider Transactions Over The Last Year

In fact, the recent purchase by Hongbo Lu was the biggest purchase of Zenas BioPharma shares made by an insider individual in the last twelve months, according to our records. Although we like to see insider buying, we note that this large purchase was at significantly below the recent price of US$26.59. Because the shares were purchased at a lower price, this particular buy doesn't tell us much about how insiders feel about the current share price.

While Zenas BioPharma insiders bought shares during the last year, they didn't sell. The average buy price was around US$16.58. To my mind it is good that insiders have invested their own money in the company. However, you should keep in mind that they bought when the share price was meaningfully below today's levels.

Insiders own 1.6% of Zenas BioPharma shares, worth about US$18m. We've certainly seen higher levels of insider ownership elsewhere, but these holdings are enough to suggest alignment between insiders and the other shareholders.

What Might The Insider Transactions At Zenas BioPharma Tell Us?
