Taser Calls Surge, Shares Gain Before Earnings Report Next Week

Trading of bullish Taser International Inc. options jumped to the highest in almost two years as investors boosted wagers that the world’s largest maker of stun guns will pare this year’s loss after reporting results next week.

More than 12,000 calls to buy the stock changed hands, 38 times the four-week average and 36 times the number of puts to sell. The shares climbed 8.3 percent to $4.17 at 12:09 p.m. in New York. Taser has rebounded from an almost 16-month low of $3.70 on July 1. It peaked in 2010 at $7.63 in February.

Taser, based in Scottsdale, Arizona-based, will report a second-quarter loss of 1 cent a share on July 27, according to the average of four analyst estimates in a Bloomberg survey.
