** Brokerage UBS starts coverage on TASER maker Axon Enterprise AXON.O with "neutral" rating and $820 PT

** PT implies a 9.94% upside to the stock's last close

** UBS expects Axon’s revenue to grow by 21% annually over the next five years, fueled by expansion in U.S. and international public safety markets, increased enterprise adoption, and the development of new technologies such as drones

** Brokerage says Axon’s strong growth prospects are already factored into the current share price, so risk and reward are balanced

** UBS notes that while Axon's international and enterprise segments are currently smaller contributors, international revenue grew 37% last year, and could become the company’s largest segment in the future, though both remain in the early stages of growth

** As of last close, AXON stock up 25.5% YTD
