Quiksilver Shares Slip for Second Straight Day

Quiksilver Inc.’s stock has tumbled 17% in the two days since the Costa Mesa-based company announced impressive second-quarter financial results, including a 78.6% profit jump.

The sportswear company issued a new release Thursday saying it is unaware of any events or developments that would account for the slumping price and heavy trading.

Analysts said the price may have slipped because the company did not bolster Wall Street’s expectations for the second half of the year during a conference call Wednesday morning.

But analysts remained positive about the company, which also reported a sales jump of 63.9% for the quarter ended April 30. “I feel like this sell-off is overdone,” said Mitchel J. Kummetz, an analyst with A.G. Edwards. “I still feel very strongly about the company and everything that’s going on.”

The stock closed Thursday at $24, down $2.25 a share, as more than 1 million shares changed hands on the New York Stock Exchange, more than five times higher than the average daily volume over the past three months. The shares fell $2.69 on Wednesday.
