Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Star Scientific were flying out of the gate this morning, jumping as much as 15% after promising results were released on a study of its Anatabloc medication.

So what: The preliminary report on the anti-inflammatory supplement showed "a clear and statistically significant difference in the treated group as compared to the placebo group." The full report has not been completed yet, but a doctor working on said it was "remarkable" that a dietary supplement like Anatabloc could lower thyroid antibody activity.


Now what: Anatabloc, introduced in 2011, is one of Star Scientific's two major products along with CigRx, a dietary supplement designed to help quit smoking, so any additional proof of Anatabloc's effectiveness could be a major driver of future sales. If the full report confirms the initial results, the stock should move higher, but I'm still a bit wary. Based on the stock history and the current valuation, the company operates and behaves like a development-stage pharmaceutical company, and the share price has dropped off a cliff several times. Clearing the preliminary hurdle is definitely good news, but I'd feel more confident about the stock once the full report is in.
