Thursday's Health Winners & Losers

Health stocks were still down on mixed earnings Thursday, as biopharmaceutical concern Dendreon(DNDN) continued its nosedive.

Dendreon fell an additional 12%, or 79 cents, to $5.54 Thursday, a day after a 64% plunge sparked by a regulatory setback. The Food and Drug Administration on Wednesday requested more information about Provenge, the company's prostate cancer treatment.

Micrus Endovascular (MEND) slid 11% after reporting a quarterly loss. The neurological device maker reported a loss of $1.4 million, or 9 cents a share, compared with a loss of $2.5 million, or 18 cents a share in the year-ago quarter.

Even companies exceeding expectations suffered declining share prices.

MedCath(MDTH), which owns and operates hospitals, reported net income of $6.3 million, or 30 cents a share, compared to a loss of $1.9 million, or 10 cents a share in the same period last year. That beat analysts' earnings expectations of 27 cents a share. The 2006 figure includes "unusual items" that unfavorably affected the stock by 4 cents a share. Despite the profit, the company's shares were recently down $1.86, or 5.6%, to $31.35.
