Anyone interested in Sera Prognostics, Inc. (NASDAQ:SERA) should probably be aware that the President, Evguenia Lindgardt, recently divested US$364k worth of shares in the company, at an average price of US$9.37 each. On the bright side, that sale was only 4.1% of their holding, so we doubt it's very meaningful, on its own.

Sera Prognostics Insider Transactions Over The Last Year

Notably, that recent sale by Evguenia Lindgardt is the biggest insider sale of Sera Prognostics shares that we've seen in the last year. That means that even when the share price was slightly below the current price of US$9.46, an insider wanted to cash in some shares. As a general rule we consider it to be discouraging when insiders are selling below the current price, because it suggests they were happy with a lower valuation. However, while insider selling is sometimes discouraging, it's only a weak signal. It is worth noting that this sale was only 4.1% of Evguenia Lindgardt's holding.
