Anyone interested in Spero Therapeutics, Inc. (NASDAQ:SPRO) should probably be aware that the CEO, CFO, Esther Rajavelu, recently divested US$207k worth of shares in the company, at an average price of US$2.36 each. The eyebrow raising move amounted to a reduction of 34% in their holding.
In fact, the recent sale by Esther Rajavelu was the biggest sale of Spero Therapeutics shares made by an insider individual in the last twelve months, according to our records. That means that an insider was selling shares at below the current price (US$2.39). When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent valuation. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. We note that the biggest single sale was only 34% of Esther Rajavelu's holding.
