4. Star Scientific ( CIGX) Company Profile: Star Scientific develops dissolvable smokeless tobacco products, which are billed as delivering fewer carcinogenic toxins. Shares of Star Scientific began surging in March on reports that compound RCP-006, which the company says is a "nutritional supplement," has potential in treating Alzheimer's. TheStreet's Adam Feuerstein notes that RCP-006, also known as anatabine, "might one day be a cure for Alzheimer's, but it's very premature to make such a claim since this nutritional supplement (not even a drug) has not yet been tested in humans, let alone humans with Alzheimer's." That skepticism hasn't kept the shares from rising. The stock did take a hit in April before the Food and Drug Administration said it will regulate smokeless electronic cigarettes as it does with traditional tobacco products. Shares are now near their all-time high. Current Share Price: $4.96 (June 27) 2011 Total Return: 154% Analyst Ratings: No research analyst follows Star Scientific.
