What happened
Shares of the commercial stage pharmaceutical company Siga Technologies (SIGA 0.91%) are on fire Monday. Specifically, the drugmaker's stock was up by a hefty 23%, on higher-than-normal volume, as of 10:28 a.m. ET Monday morning.
What's sparking this double-digit gain? Siga's stock is bolting higher in response to the World Health Organization's decision to declare the ongoing monkeypox outbreak a global health emergency. To date, there have been over 16,000 cases of monkeypox across 75 countries.
So what
Siga's Food and Drug Administration (FDA)-approved smallpox medication, known as Tpoxx (generic name: tecovirimat), was previously approved as an oral treatment for monkeypox in the United Kingdom and Europe. The company, in turn, will likely see a sizable surge in demand for this antiviral medication overseas. In fact, Siga already reported a significant uptick in orders for the drug from multiple international jurisdictions last month.

Key Data Points
In the U.S., Tpoxx also may also end up being used against the monkeypox outbreak. But such a move is far from certain. As things stand now, the drug can only be prescribed for monkeypox in the U.S. on a compassionate basis. Unfortunately, this rather stringent regulatory pathway is insufficient to deal with a full-on epidemic.
Now what
Is Siga's stock still a red-hot buy? Given the unpredictable nature of U.S. regulatory agencies in emergency situations such as this one, investors may want to take a cautious approach with this speculative monkeypox play right now. Siga's shares, after all, are now trading at an all-time high after today's latest move northward.
