Morning Money Memo:

The unrest in Ferguson, Missouri, is having a dramatic effect on shares of Taser International Inc. (TASR). The Scottsdale, Arizona-based company, best known for its electroshock "stun" guns, has seen its share price jump 19 percent in the past five trading days. Investors are betting that allegations of heavy-handed police tactics, including the shooting of an unarmed teenager, will lead to a big increase in sales of Taser's "body cameras" that can be worn by officers while on patrol.

The latest sign of U.S. economic revival comes in the second-quarter earnings report by America's biggest home improvement chain. Profits at Home Depot jumped 14 percent thanks to a rebound in its spring selling season. Sales at U.S. stores open at least a year jumped 6.4 percent and the retailer raised its full-year profit estimate. Spring is the biggest season for home-improvement retailers, as homeowners and others work on their yards and gardens. While the season started off cold and stormy, weather improved and shoppers headed out to stores to pick up supplies. The report from Home Depot beat Wall Street forecasts. The company's share price is up more than 3 percent this morning.
