Its proprietary SNAP platform enables rapid iteration and optimization, supporting a competitive edge in early-stage drug discovery.
Foolish take
Director Robert More's $5 million share sale in November was part of a Rule 10b5-1 trading plan and does not indicate any change in conviction in the part of the insider. More still retains nearly 4 million shares of the biotech company, in fact, valued at current prices around $77.6 million.
The stock is up more than 80% year to date as of Dec. 23, trouncing the S&P 500's impressive total return of 18.4% over the same period. It announced its third-quarter financial results in early November, before More's recent share transaction. In it, the company reported slightly higher research and development (R&D) and selling, general, and administrative (SG&A) expenses as well as a slightly higher net loss over the year-ago period.
In December, the company announced two new appointments to the management team: Bhavesh Ashar as Chief Operating Officer and Heather Faulds as Chief Regulatory Officer.
Wall Street analysts forecast significant upside potential for the stock, generally rating Tyra a moderate buy or buy. However, the biotech company is early-stage and doesn't generate any revenue, which makes it an inherently risky investment.
