Shares of Black & Decker ( BDK) were among the NYSE's big winners Monday after the company reported better-than-expected second-quarter earnings and said full-year earnings would top analysts' expectations.

The Towson, Md.-based company reported a second-quarter profit of $1.50 a share on sales of $1.3 billion. Analysts polled by Thomson First Call had expected it to report earnings of $1.26 a share on sales of $1.24 billion. Black & Decker attributed the strong quarterly results to cost savings and sales volume leverage. A year ago it earned 98 cents a share on sales of $1.1 billion. Looking ahead, it expects to earn $1.25 to $1.30 a share in the third quarter and $5.05 to $5.15 for the full year. Analysts are looking for the company to earn $1.28 a share in the third quarter and $4.88 a share for the full year. Shares of Black & Decker traded up $7.17, or 11.9%, to $67.49.

Taser ( TASR) fell almost 10% after The New York Times reported on concerns about the safety of its stun-guns. The paper said Taser has conducted few meaningful studies on the guns, which are gaining increasing acceptance by U.S. police departments and resulted in six deaths last month alone. The company criticized the story, saying the Times made no mention of the many instances in which Taser's have provided a nonlethal option for police who otherwise would've used guns. The stock tanked $3.92 to $36.32.

Mattel ( MAT) rose after it reported better-than-expected second-quarter earnings and sales. Earnings of 6 cents a share topped analysts' expectations of 5 cents a share.

Strong sales in its American Girl and Fisher-Price divisions helped it overcome continued weakness in its Barbie brand. Shares of Mattel traded up 65 cents, or 3.9%, to $17.41.
