Foolish take

Chief Accounting Officer George Clark's purchase of additional Biohaven stock suggests he believes shares will appreciate in value. He bought the stock just days after it hit a 52-week low of $7.48 on Nov. 11. That's a significant drop from its high of $47.75 reached nearly a year ago.

Biohaven shares fell after the U.S. Food and Drug Administration (FDA) rejected the company's request for approval of its lead drug, troriluzole, on Nov. 4. Days later, on Nov. 10, Biohaven announced cost-cutting efforts.

This action makes sense since Biohaven does not currently generate any revenue. As an early-stage biotechnology company, it needs regulatory approval of its drugs before it can start selling them.

Consequently, Biohaven suffered a net loss of $173.4 million in the third quarter, up from $160.3 million in the prior year. It exited Q3 with cash and investments totaling approximately $264 million, and to bolster its balance sheet, the company implemented an equity offering that generated about $200 million.

Despite these additional funds, Biohaven's business looks precarious. Given the FDA's rejection, the company may not survive over the long term. As a result, the prudent approach is to hold off investing in Biohaven at this time.
