WSJ.com - Ahead of the Tape: "Monday night, the CBS network ran a report about Taser, the maker of 'nonlethal' stun guns for police departments, raising questions about whether Taser's products were associated with some people getting stunned in a rather permanent sense. Taser responded with another stock split.
Stock splits have nothing to do with what a company is doing to earn -- what is the word? -- a profit. Therefore, by one quaint reckoning, they shouldn't affect the stock price. Though this reality was repeated thousands of times between 1996 and 2000, it seems not to have sunk in too well.
Yesterday, Taser rose $13.75, or 18%, to $92.25 on volume of 19.8 million shares. (The stock had fallen 7.7% on Monday ahead of the CBS report.)"
